quality voice reproduction into several bands, and uses dedicated voice amplifiers and speakers
for each frequency band @ The exogenous device is considered, and the acoustic device 1lllc of

1. , M, H 0, and the low end, middle sound, and 4 sound are respectively dedicated power
increasers, 1. It is exposed to radiation, and the speaker for large bass W1 is the speaker for f
during f, the sound is squeezed 4 by the ? ? f city Sbi cate -1. The equivalent number of power
amplifiers is eight. In general, a power amplifier is essentially one, and it can not be overwhelmed
by the number of cycles required to complete it with a single t4. If the above-mentioned
conventional reproduction device is not economical. Book-J # draft: in view of the above points,

speaker WtIP and a speaker for high-pitched sound are both positive shield Vc @. However, it is
preferable that a large signal in the low frequency range be added to the speaker T during the II

filter with a single cost filter, you can use a general Lo1m + network store as shown in Figure 4.

it is amplified without mousing in # L- in the low-pitched edge and the middle a-range butterfly 1
power 111 B and 4 m, respectively, and it is the sci-ka W for tii-. It is pronounced from 4 sound

other by the power -4 power, and the middle sound speaker 4f4 peak f speaker 8! It is also
pronounced. Also in the case of Jin, VC AK may be continued to # # of the output of 44 AK 71 'C

to the multi-channel audio reconnaissance unit 111 / c of the present invention, the power
increase SS of 1 @ / 1 and / or multiple frequency bands in close proximity to each other is used.
Therefore, the number of the power amplification IIO used can be greatly reduced to 1I111Il, and
has an f-value and a ^ -characteristic configuration. A brief description of the surface 4a The first
