Wi Wi Wi s . Loudspeakers 41 of W than before! The pupil is used, but these oit amount, the
sound quality adjustment method can be roughly divided into the following two if roughly
divided. As shown in FIG. 1A, a voice from a 1 / 1jlIIIg- shown is applied as 1-alk, and 2-- "for the
input terminal 1 and for high-pitched and mid-tone, each speaker for sound 2. 11, 4 and am tube

pressure! It is 40 of the composition which can spend IIJ wave number paradox. As shown in tz
@, one is a high-pitched, middle-tone (14+) wave circuit S,... And a high-pitched, mid-tone Ospeaker 2, an attenuator 8 for easy-to-high-pitched and mid-tone , 9t-inserted in series and
adjusting the attenuator 9, 9 by changing the speaker laziness, the input level to S ? ?,
changing the frequency inertia of the entire device Ii! ????????? However, in any of the
above-mentioned devices, the control of the frequency range of the control itself as well as the
level town variable is IIL! If the characteristics of the l-path and the speaker are large enough,
there is a drawback. The present invention overcomes the disadvantages of the subject, and will
be described in conjunction with the river, 4 $ -J, about 0'11894 below. Gran, No. 311, grade 1-,
same as component Wc, same letter-letter No. and detailed 11 @ omitted. In II, it is a level
control-path, and since it has a beak characteristic or a pitch 41, it is configured as a Jliij path,
and it is 11J34 that it is possible to rebuke an arbitrary frequency level. O 8-? input the level
