DESCRIPTION JP2005252328
PROBLEM TO BE SOLVED: To monitor a CUE signal in real time when detecting a signal of an
input channel. SOLUTION: When an input channel is CUE, a changeover switch SW is
automatically switched to a contact b side, and a CUE signal from a CUE bus 46 bypasses a CUE
delay unit 80. Thereby, it is possible to cue the signal of the real time input channel. When the
output channel is CUE, the changeover switch SW is automatically switched to the contact a side,
and the CUE signal from the CUE bus 46 is delayed by the CUE delay unit 80. This makes it
possible to absorb the time difference between the sound heard from the main speaker and the
CUE signal that the operator is listening to. [Selected figure] Figure 6
Mixing equipment
[0001]
The present invention relates to a mixing apparatus capable of detecting a signal of an input
channel or an output channel.
[0002]
Conventionally, the levels and frequency characteristics of the signals output from a large
number of microphones or electric and electronic musical instruments are adjusted, mixed,
combined into several mixing groups, and sent out to power amplifiers and various recording
devices, effectors and performances. A mixing device is known which delivers to the playing
player.

The operator who operates the mixing device adjusts the volume and timbre of each audio signal
of instrument sound and singing to the state considered to be most representative of the
performance by operating various panel controls on the mixing console. doing. The mixing
apparatus includes a plurality of input channels as an input signal series, a bus for mixing the
signals output from the input channels, and an output channel which is an output series for
outputting the mixed signals. Each input channel controls the frequency characteristic and
mixing level of the input signal and outputs it to each mixing bus, and each mixing bus mixes
each input signal and outputs it to the corresponding output channel. Each output channel
controls and outputs the level of the mixing signal input from the mixing bus.
[0003]
In such a mixing apparatus, a CUE function for detecting a signal of an input channel or an
output channel without changing the mixing state in the mixing means, and a signal output from
the output channel and supplied to a speaker A monitoring function to monitor is generally
provided. In a mixing device having a CUE function, the signal of the selected input channel or
output channel is input to the CUE bus by turning on the CUE switch of the channel strip
controlling each input channel or each output channel, and the CUE bus Signal (CUE signal) is
output from a headphone, a speaker or the like which is a sound system for monitoring by the
operator.
[0004]
In this case, at least the output channel is provided with channel delay means for setting a
channel delay for controlling the delay amount of the signal of the output channel in order to
adjust the phase relationship with the signal of the other output channel. The channel delay of
the output channel is adjusted to adjust the localization at the listening position of the audience
in the sound output from the main speaker. In the monitor function, the signal from the channel
delay means is used as a monitor signal so as to monitor the signal delayed by the channel delay
means. Also, at the position of the operator of the mixing apparatus, the sound heard from the
main speaker is accompanied by a propagation delay, and the monitor signal is delayed to absorb
the time difference with the monitor signal or CUE signal observed by the operator. A monitor &
CUE delay unit is provided which includes delay means for delaying and CUE signal delaying
means.

[0005]
In this monitor & CUE delay unit, CUE delay is applied to the CUE signal even when the signal of
the input channel is CUE. However, since the signal of the input channel is a signal before mixing
and is only a part of the acoustic signal output from the main speaker, there is no need to
monitor the acoustic signal in phase. . Rather, it is desirable to monitor undelayed real-time CUE
signals when listening to the input channel signal, but in conventional mixing devices, when
monitoring the input channel signal, the monitor & CUE delay unit There is a problem that the
real time CUE signal can not be monitored because it is delayed.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a mixing
apparatus capable of monitoring a CUE signal in real time when detecting a signal of an input
channel.
[0007]
In order to achieve the above object, the mixing device according to the present invention does
not delay the signal of the input channel to be listened to by monitoring and CUE delay means
being bypassed when the signal of the input channel is selected by the CUE means That is the
most important feature.
[0008]
According to the present invention, when the signal of the input channel is selected by the CUE
means, the monitor / CUE delay means is bypassed so that the signal of the input channel to be
listened to is not delayed. It becomes possible to monitor real-time CUE signals when listening to
the signals.
[0009]
When the signal of the input channel is selected by the CUE unit, the monitor / CUE delay unit is
bypassed and the input channel is listened to when monitoring the signal of the input channel.
This is realized by not delaying the signal of.

Next, FIG. 3 shows an equivalent functional block diagram in which the mixing process is
performed in the digital mixer 1 of the configuration shown in FIG. 1 according to the present
invention. In FIG. 3, an analog signal input to an analog input unit (A input) 40 having a plurality
of analog input ports is converted into a digital signal by an incorporated AD converter and input
to an input patch 43. The digital signal input to the digital input unit (D input) 41 having a
plurality of digital input ports is input to the input patch 43. Further, the digital mixer 1 is
provided with a built-in effector 42 composed of, for example, eight effectors, and a signal to
which an effect is applied by the built-in effector 42 is also input to the input patch 43. Here,
each effector of the built-in effector 42 has a plurality of virtual digital output ports as input
portions of a plurality of signals to the effector and a virtual portion as output portions of a
plurality of signals to which an effect is applied by the effector. And a plurality of digital input
ports.
[0016]
The input patch 43 selectively patches (connects) any one input port of the plurality of input
ports which are the signal input sources for each input channel of the plurality of input channel

units 44, for example, 24 channels. Each input channel is supplied with the signal from the input
port patched by the input patch 43. Each input channel in the input channel unit 44 is provided
with a limiter, a compressor, an equalizer, a channel delay means, a level adjustment unit to the
MIX bus 45 and the CUE bus 46 of the fader, and in these input channels, frequency
characteristics and The levels sent to the MIX bus 45 and the CUE bus 46 are controlled. The
digital signals of 24 channels output from the input channel unit 44 are selectively output to one
or more of 12 mixing buses (MIX buses) 45 of MIX 1 to 12 and are output to the CUE bus 46.
[0017]
The MIX bus 45 mixes one or a plurality of digital signals selectively input from any one of 24
input channels in each of 12 buses, and a total of 12 MIX output is a MIX output channel. It is
output to the unit (MIX output ch) 47. This makes it possible to obtain 12 channels of MIX
output mixed in 12 ways. The output from the MIX bus 45 is often supplied as a final output to a
speaker or the like. Each output channel in the output channel section 47 is provided with a
compressor, an equalizer, channel delay means, and a level adjustment section to the output
patch 48 of the fader, and these output channels are sent to the frequency characteristic and
output patch 48 Level is controlled. The CUE bus 46 selectively receives the digital signal of 24
channels output from the input channel unit 44 and also selectively receives the digital signal of
12 channels output from the MIX output channel unit 47. It is done. The CUE mode in the CUE
function has two modes, the last CUE and the mix CUE, and the two modes will be described
below.
[0018]
In the last CUE mode, when the CUE switch 21d of the channel strip 21 that controls a channel
not performing CUE is operated, the CUE of the channel that was performing CUE so far is
canceled, and the operated channel of CUE switch 21d Only the channel controlled by the strip
21 will be cueed. That is, in the last CUE mode, only the CUE of the new channel operated by the
CUE switch 21d is performed, and at the same time, only one channel can be used for CUE. The
CUE switch 21d is self-illuminating, and only the CUE switch 21d of the channel strip 21 being
CUE is turned on, and the CUE switches 21d of the other channel strips 21 are turned off. In
addition, the signal to CUE is made to be able to select the point before or behind the motorized
fader 17 in each channel. In this case, the point from which the CUE signal is taken out is
selected not for each channel but for all channels in common. When the CUE switch 21d of the
channel strip 21 which has already been CUE is further operated, the CUE of the channel is
canceled and the CUE switch 21d is turned off.

[0019]
Further, in the mixed CUE mode, a plurality of channels belonging to each group can be
simultaneously CUEd. The groups are divided into groups of input channels and groups of output
channels. When the CUE switch 21d of a new channel is operated in the mixed CUE mode, if the
previous CUE channel belongs to the same group as the newly CUE-operated channel, the
previous CUE channel remains, The channel on which the CUE switch 21d is operated is also
CUE. In this manner, in the mixed CUE mode, it is possible to simultaneously CUE multiple
channels, and the signals of the CUE points in each channel to be CUE are output to the CUE bus
46, and the signals of the plurality of channels CUE on the CUE bus 46 are mixed It is output as a
CUE signal. In this case, since the input channel group is different from the output channel group,
when the CUE switch 21d that controls the output channel is operated when the input channel is
CUE, the CUE of the input channel is canceled and newly added. A group of output channels
operated by the CUE switch 21d can be mixed CUE.
[0020]
The last CUE mode and the mix CUE mode can be switched by a mode selector switch (not shown
in FIG. 2), and the CUE signal is output from the CUE bus 46 and supplied to the delay &
switching unit 53 regardless of which mode is set. Be done. A signal of one or more channels
selected by the monitor selector 51 is mixed in the monitor mixer unit 52 and supplied to the
delay & switching unit 53 as a monitor signal in addition to the CUE signal. Then, the delay &
switching unit 53 switches the supplied CUE signal and the monitor signal and inputs the signal
to the monitor analog output unit 54. Furthermore, the delay & switching unit 53 delays the CUE
signal and the monitor signal so as to absorb the time difference between the sound heard from
the main speaker and the monitor signal or CUE signal being observed by the operator at the
position of the operator. doing. The monitor analog output unit 54 converts the input digital
monitor signal into a monitor analog signal by a built-in DA converter, and outputs the analog
signal from the monitor analog output port. The monitor analog signal output from the monitor
analog output port is amplified and output from the monitor speaker and headphone terminal
25.

The MIX output of 12 channels output from the MIX output channel unit 47 is supplied to the
output patch 48. In the output patch 48, any one of the 12 channels of the MIX output channel
unit 47, which is an input source of the signal, is output from each of the analog output port unit
(A output) 49 and each digital output port unit (D output) 50. Each output port can be selectively
patched (connected), and each output port is supplied with the signal from the channel patched
by the output patch 48. Further, in the built-in effector 42 to which the signal patched by the
output patch 48 is input, reverb, echo and chorus effects are added to the digital audio signal.
The built-in effector 42 is also realized by the DSP constituting the signal processing unit 15. In
the built-in effector 42, an output obtained by applying an effect to the input signal is returned to
the input patch 43.
[0022]
Also, the digital output signal supplied to the analog output port unit (A output) 49 having a
plurality of analog output ports is converted into an analog output signal by the built-in DA
converter and output from the analog output port. Then, the analog output signal output from
the analog output port unit (A output) 49 is amplified and emitted from the speaker. The digital
audio signal output from the digital output port unit (D input) 50 having a plurality of digital
output ports is supplied to a multitrack recorder, DAT or the like so that digital recording can be
performed.
[0023]
Next, FIG. 4 shows a configuration example of an input channel 44 a for one channel in the 24
channel input channel section 44. As shown in FIG. 4, in the input channel 44a for one channel,
the signal input from the input patch 43 has its level and frequency characteristics adjusted by
the processing unit 60 such as a limiter, compressor, equalizer (EQ), etc. The predetermined time
is delayed at 61. The signal is delayed by the channel delay means 61 in order to match the
timing with the signal in the other input channel. By this channel delay means 61, in the case of a
stereo signal, the timing of L and R channels can be matched. The signal output from the channel
delay means 61 is supplied to the fader (FADER) and to the contact a of the pre-post changeover
switch (PP) for CUE. A signal whose level is controlled by the fader (FADER) is supplied to the
contact b of the pre / post changeover switch (PP) via the input channel switch (CH_ON). A signal
output from the movable contact c of the pre / post changeover switch (PP) is supplied to the
CUE bus 46 via the CUE switch (CUE_ON). This pre-post switch (PP) allows the signal to be cueed
to be switched to the signal before or after the fader (FADER).

[0024]
Here, when the CUE switch (CUE_ON) is turned on by switching the pre-post switch (PP) of the
input channel 44a to the contact a side, the signal from the channel delay means 61 is supplied
to the CUE bus 46, It becomes possible to cue the input channel signal before being levelcontrolled by the fader (FADER). Also, when the pre-post switch (PP) is switched to the contact b
side and the CUE switch (CUE_ON) is turned on, the signal from the input channel switch
(CH_ON) at the rear stage of the fader (FADER) is supplied to the CUE bus 46 As a result, it
becomes possible to cue the input channel signal after being level-controlled by FADER.
[0025]
Further, the signal output from the channel delay means 61 is supplied to the contact a of the 12
mixing pre-post changeover switches (PP1 to PP12). The signal level-controlled by the fader
(FADER) is supplied to the contact b of the 12 mixing pre-post changeover switches (PP1 to
PP12) via the input channel switch (CH_ON). The signals output from the movable contacts c of
the 12 mixing pre-post switches (PP1 to PP12) have their transmission levels adjusted by 12
transmission level adjustment means (SND_L1 to SND_L12), respectively, and 12 signals Each of
12 MIX buses 45 is supplied via the transmission switch (SND_ON1 to SND_ON12).
[0026]
Here, when the 12 mixing pre-post changeover switches (PP1 to PP12) are switched to the
contact a side and the transmission switches (SND_ON1 to SND_ON12) are turned on, the signal
before being level-controlled by the fader (FADER) Are supplied to the 12 MIX buses 45 and
mixed on the MIX buses 45. Also, when the 12 mixing pre-post switches (PP1 to PP12) are
switched to the contact b side and the sending switches (SND_ON1 to SND_ON12) are turned on,
the signal before level control is performed by the fader (FADER) The 12 MIX buses 45 are
supplied to be mixed on the MIX bus 45. The setting of the pre / post changeover switches (PP1
to PP12), the transmission level adjustment means (SND_L1 to SND_L12) and the transmission
switches (SND_ON1 to SND_ON12) is performed as desired for every 12 MIX buses 45.
[0027]

Next, FIG. 5 shows a configuration example of an output channel 47 a for one channel in the 12
output channel sections 47. As shown in FIG. 5, in the output channel 47a for one channel, the
signal output from any of the 12 MIX buses 45 has its level and frequency characteristics
adjusted by the processing unit 70 such as a compressor or equalizer (EQ). Ru. The signal output
from the processing unit 70 is supplied to the fader (FADER) and also supplied to the contact a of
the pre-post changeover switch (PP) for CUE. The signal whose level is controlled by the fader
(FADER) is supplied to the channel delay means 71 and also supplied to the contact b of the pre /
post changeover switch (PP) via the output channel switch (CH_ON). The channel delay means
71 is adjusted to adjust the localization at the listening position of the audience in the sound
output from the speaker to which the output from the output port is supplied. Further, a signal
output from the movable contact c of the pre / post changeover switch (PP) is supplied to the
CUE bus 46 via the CUE switch (CUE_ON).
[0028]
Here, when the pre-post switch (PP) of the output channel 47a is switched to the contact a side
and the CUE switch (CUE_ON) is turned on, the signal from the processing unit 70 is supplied to
the CUE bus 46, and the fader It becomes possible to cue an output channel signal before being
level-controlled by (FADER). Also, when the pre-post switch (PP) is switched to the contact b side
and the CUE switch (CUE_ON) is turned on, the signal from the output channel switch (CH_ON)
that is the subsequent stage of the fader (FADER) is supplied to the CUE bus 46 It becomes
possible to cue the output channel signal after being level-controlled by the fader (FADER). The
output from the channel delay means 71 is output to the output patch 48 and to the monitor
selector 51. The input channel switch (CH_ON) in the input channel 44a and the output channel
switch (CH_ON) in the output channel 47a correspond to the channel switch 21b of the channel
strip 21 that controls the channel, and the fader of the fader (FADER) is Similarly, the CUE switch
(CUE_ON) corresponds to the CUE switch 21d, which corresponds to the fader knob 21c of the
electric fader 17.
[0029]
Next, an example of the configuration of the delay & switching unit 53 is shown in FIG. As shown
in this figure, the delay & switching unit 53 is supplied with the CUE signal from the CUE bus 46
and the monitor signal from the monitor mixer unit 52. The CUE signal from the CUE bus 46 is
supplied to the contact b of the changeover switch SW, and is delayed for a predetermined time
in the CUE delay unit 80 and supplied to the contact a of the changeover switch SW. The CUE
10-04-2019
11
signal output from the movable contact c of the changeover switch SW is level-controlled by the
gain unit 81 and is supplied to the mixer (MIX) 84. The CUE delay unit 80 compensates for the
delay time of the channel delay means 71 in the output channel unit 47 and the propagation
time until the sound emitted by the speaker reaches the operator. That is, the CUE delay unit 80
can absorb the time difference between the sound heard from the main speaker at the position of
the operator and the monitor signal or CUE signal being observed by the operator, and the user
can listen to the sound without discomfort. become able to.
[0030]
Further, the monitor signal from the monitor mixer unit 52 is delayed for a predetermined time
in the monitor delay unit 82, level-controlled by the gain unit 83, and supplied to the mixer (MIX)
84. In the mixer (MIX) 84, the CUE signal output from the gain unit 81 and the monitor signal
output from the gain unit 83 are mixed, and the mixed signal is output from the monitor analog
output unit 54. Similar to the CUE delay unit 80, the monitor delay unit 82 compensates for the
delay time of the channel delay means 71 in the output channel unit 47 and the propagation
time until the sound emitted by the speaker reaches the operator. .
[0031]
When the group of channels to be CUE is made the group of output channels, the changeover
switch SW is automatically switched to the contact a side, and the CUE signal is delayed by the
CUE delay unit 80 for a predetermined time as described above. This makes it possible to listen
to the signal of the output channel without a sense of incongruity with the sound from the
speaker. When the group of channels to be CUE is set as the group of input channels, the
changeover switch SW is automatically switched to the contact b side, and the CUE signal
bypasses the CUE delay unit 80. This is because the signal of the input channel is a signal before
mixing and is only a part of the acoustic signal output from the main speaker, so it is necessary
to listen to the acoustic signal in phase. Rather, it is desirable to monitor real-time CUE signals
without CUE delay when monitoring signals on the input channel.
[0032]
Furthermore, when either the input channel or the CUE switch (CUE_ON) of the output channel is
turned on, the gain of the gain unit 83 is automatically reduced and the monitor signal from the
10-04-2019
12
monitor mixer unit 52 is attenuated. At the same time, the gain of the gain section 81 is raised to
increase the CUE signal from the CUE bus 46. Although setting of gains by the gain units 81 and
83 can be arbitrarily set, when monitoring a CUE signal, some monitor signals can be heard. Also,
when any of the CUE switches (CUE_ON) is turned off, the gain of the gain section 81 is
automatically narrowed to the maximum, and the CUE signal from the CUE bus 46 is hardly
output, and The gain of the section 83 is raised to increase the monitor signal from the monitor
mixer section 52. Thus, the CUE signal can not be heard when monitoring the monitor signal.
[0033]
Next, FIG. 7 shows a flowchart of operation event processing of CUE (i) SW executed when any of
the CUE switches 21d of the input channel or the output channel is operated. The program for
executing the operation event processing of the CUE (i) SW is one of the mixing control programs
stored in the flash memory 11. When one of the CUE switches 21d of the input channel or the
output channel is operated, the operation event processing of the CUE (i) SW is activated, and in
step S10, CH (LN) for identifying the operated channel of the CUE switch 21d. , I) are replaced by
channel c. In this case, CH (LN, i) is indicated by the identification number LN indicating either
master 1, layer 1 or layer 2 controlled by the channel strip 21 and the i-th of the channel strips
21 for 12 channels, The ith channel strip 21 corresponds to either an input channel or an output
channel to be controlled. Also, channel c is a channel number that can indicate any one of the
input and output channels. Here, when the channel controlled by the channel strip 21 is layer 1
(1 to 12 input channels), the channel c is one of the channels 1 to 12, and the channel controlled
by the channel strip 21 is layer 2 (13 Channel c is one of channels 13 to 24 when it is set to 24
input channels, and channel c is a channel when the channel controlled by channel strip 21 is set
to master 1 (1 to 12 output channels) It is considered as one of 25-36. Thus, all input channels
and output channels are identified by channels 1 to 36.
[0034]
Next, in step S11, it is determined whether the CUE switch (CUE_ON) on the channel c is off and
CON (c) = 0. CON (c) indicates the on / off state of the CUE of channel c. When CON (c) is “0”,
CUE is off and when CON (c) is “1” CUE is turned on. Here, if the CUE switch (CUE_ON) in the
channel c is off (CON (c) = 0), it is determined as YES, and the process branches to step S17. In
this case, since the CUE switch (CUE_ON) that has been turned off is operated and turned on, the
following on-event processing is performed. That is, at step S17, the value of CS indicating the
group in the CUE is confirmed. In this case, when CS is "0", CUE of any group is turned off, and
when CS is "1", the group of input channels is CUE and CS is "2". In this case, a group of output

13
channels is being cueed. Therefore, as a result of confirming the value of CS and determining
whether the group to which channel c belongs is CUE, if it is determined that the group to which
channel c operated CUE switch (CUE_ON) belongs is CUE, step S22. Then, it is determined
whether the value of MC is "0". MC is a value indicating the state of the CUE mode. When MC is
“0”, it indicates that the single CUE mode, that is, the above-mentioned last CUE mode is
selected, and when MC is “1”, MIXCUE It indicates that the mode, that is, the above-mentioned
mixed CUE mode is selected.
[0035]
When the value of MC is "0" in this step S22 and it is determined that the single CUE mode is set,
the process branches to step S24 and the CUE switch (CUE_ON) is operated with CON (c) set to
"1". The CUE of the other channel c is turned ON, and the CON of all the other channels is set to
"0" to cancel the CUE of all the other channels. Then, the operation event processing of CUE (i)
SW ends. If it is determined in step S22 that the value of MC is "1" and it is not determined that
the single CUE mode is set, the process proceeds to step S23, and CON (c) is set to "1", and the
CUE switch (CUE_ON) The CUE of the operated channel c is turned on. In this case, channel c is
CUE simultaneously with the channel on which another CUE is turned on. Then, the operation
event processing of CUE (i) SW ends.
[0036]
When it is determined that the group to which the channel c operated by the CUE switch
(CUE_ON) belongs is not in CUE when the value of CS is confirmed in step S17, the process
branches to step S18. In this case, since the group to be CUE is changed, the CON of all channels
is set to "0" in step S18, and the CUEs of all channels are turned off. Next, in step S19, it is
determined whether to bypass the CUE delay unit 80 according to the group to which the
channel c operated by the CUE switch (CUE_ON) belongs. In this case, when it is determined that
the group is a group of input channels, the changeover switch SW is switched to the contact b
side to bypass the CUE delay unit 80 and to obtain a CUE signal that is not delayed. When it is
determined that the group is the output channel group, the changeover switch SW is switched to
the contact a side, and the CUE delay unit 80 delays the CUE signal. Thereby, it is possible to
eliminate the time difference between the sound heard from the main speaker at the position of
the operator and the CUE signal that the operator is listening to.

When the process of step S19 ends, the gain of the gain unit 83 is automatically narrowed so
that the CUE signal becomes a main monitor analog output in step S20, and the monitor signal is
attenuated and the gain of the gain unit 81 is reduced. CUE signal is enlarged. Next, a number
indicating that the group to which the channel c operated by the CUE switch (CUE_ON) at step
S21 belongs to CUE ("1" when the group is the input channel, the group is the output channel In
the case, the CS is rewritten to "2", and the process proceeds to step S22. As described above,
when the CUE mode is set to the single mode (last CUE mode) as described above, only the
channel c operated by the CUE switch (CUE_ON) is CUE, and the other group is the same. The
CUEs of all channels of are processed to be canceled. When the CUE mode is set to the MIXCUE
mode (mix CUE mode), the channel c on which the CUE switch (CUE_ON) is operated is processed
so as to be added to the channel being CUE of the same group. Thus, the operation event
processing of CUE (i) SW ends.
[0038]
Further, when the CUE switch (CUE_ON) on the channel c is turned on in step S11 (CON (c) = 1),
it is determined as NO and the process proceeds to step S12. In this case, since the CUE switch
(CUE_ON) that has been turned on is operated and turned off, the following off event processing
is performed. That is, in step S12, CON (c) is set to "0", and the CUE of the channel c on which the
CUE switch (CUE_ON) is operated is turned off. Next, at step S13, the value of MC is set to "0",
and it is determined whether or not the single CUE (last CUE) mode is set. Here, if it is
determined that MC = 0 and the single CUE (last CUE) mode is determined, the CUEs of all the
channels are turned off, so the process branches to step S15 and the monitor signal is an analog
output for monitoring. As a result, the gain of the gain unit 81 is automatically reduced to the
maximum so that the CUE signal is hardly output, and the gain of the gain unit 83 is raised to
increase the monitor signal. Then, in step S16, "0" is set to CS indicating the state of CUE, and the
CUEs of all channels are turned off. When the process of step S16 ends, the operation event
process of CUE (i) SW ends.
[0039]
If it is determined in step S13 that MC is not 0 and it is determined that the single CUE (last CUE)
mode is not set, the MIX CUE (mix CUE) mode is set, and the process proceeds to step S14. It is
determined whether channel CON is "0" and CUEs of all channels are off. Here, when it is
determined that the CON of all channels is “0” and the CUE of all channels is turned off, the
10-04-2019

process branches to step S15 and the monitor signal becomes the monitor analog output as
described above. As described above, the gain control of the gain unit 81 and the gain unit 83 is
performed, “0” is set to CS, and the CUEs of all the channels are turned off, and the operation
event processing of CUE (i) SW ends. . If it is determined in step S14 that the CONs of all the
channels are not set to "0" and the CUEs of all the channels are not turned off, the channels CUE
in the MIXCUE (Mix CUE) mode remain. Because of this, the operation event processing of CUE (i)
SW ends as it is.

In the mixing apparatus according to the present invention described above, an input SOLO
function that turns on only the signal of the input channel specified by SOLO among the specific
input channel signals for each bus and outputs the signal, or a plurality of output channels Some
mixing devices have an output SOLO function that turns on and outputs only the signal of the
output channel designated SOLO. Even when this SOLO function is enabled and the input channel
is designated SOLO or the output channel is designated SOLO, the monitor signal for detecting
and listening to this is sent to the monitor analog output unit 54 through the monitor delay unit
82. It is output and delayed by the monitor delay unit 82 regardless of whether it is an input
channel or an output channel.
[0041]
In the above description, although the input channel, the MIX bus 45, the output channel, and
the CUE bus 46 are described in monaural for simplification of the description, they can be
stereo in configuration. In that case, the monitor selector 51, the monitor mixer unit 52, and the
delay & switching unit 53 also have a stereo configuration so that a stereo signal can be
monitored or cueed. Furthermore, further configurations such as 5.1 ch and 7.1 ch can be
realized in the same manner. As described above, the mixing apparatus of the present invention
can have a stereo configuration or a multi-channel configuration.
