BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of
the present invention, in which S5 and S6 are 2-channel source selectors and S7 is a 4-channel
mode switch. −117−
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the use of a 4channel stereo amplifier. 04 amplifier amplifiers and power amplifiers are required to drive four
speakers when playing a 4-channel stereo system! Oh, these are housed in one case is called 4
channel 1 yannel stereo amplifier 01 This 櫨 channel stereo amplifier is used effectively in all
channels when playing 4 channels stereo. At present, there are very few signal sources
(broadcasting, recording board 1, etc.) compared to the signal sources provided for 鵞 channel
performance. Therefore, it is considered that the frequency of what was manufactured as a fourchannel amplifier provided for two-channel stereo performance is high. In this case, the 02
channel other than the 2 channel provided for performance O is not used effectively and is
wasted. At the time of this 3 channel performance, as a means to utilize the remaining 2 channel
amplifier which is not used and to increase the value, 4 power amplifiers of 4 channel stereo
amplifier are combined and connected in parallel and equivalently output power per channel
Method of constructing a large-scale 鵞 channel stereo amplifier (parallel connection method), or
BTL (BALANOBD-IIIBλN8FORMIn-LH8B) connecting two power amplifiers similarly combined,
and so on. There is a method of configuring a large two-channel stereo amplifier (BTL connection
method) (鵞) 婁. This device can be used as a completely independent two-channel stereo
amplifier if the unused two-channel amplifier can be used as a method of more effectively
utilizing the unused two-channel amplifier of the four-channel stereo amplifier in two-channel
stereo performance. ◎ 1: The 4-channel stereo amplifier is originally used for: the intended 4channel stereo performance □ 1 except when providing the 4-channel stereo amplifier with the
changeover switch. It is possible to construct an independent 2-channel stereo amplifier system
13 · · ·: Figure 0 illustrates this invention according to the illustrated embodiment is a block

the position shown Hata wins, speaker output terminal T7.
At T8, a 4-channel output voltage corresponding to the input of DI803ITIi input terminal T3 is
obtained. In the figure, 2 channels (matrix 4 channels 8Q or RM) signals selected by 87 and CK
are selected and decoded by the 8Q circuit FA-2X or the company RM + 8Q circuit PA-90. Matrix

this 4-channel matrix signal is obtained. In the figure, when 8 points are turned down to the
position of d, T-f, T8 Ktl) each 3 channel source selector '# number. And the output of 2 channels

of the record connected to the input terminal TIK is obtained at T7, and the output of the FM
broadcast tuned by the chenna is obtained at T (4) 8. When two switches for selecting a 2channel signal source and a switch for selecting a 4-channel signal source are arranged as in the
case of 86.86.87 like this, a 4-channel stereo amplifier becomes an original 4-channel stereo
amplifier from K. It is possible to provide for use as an independent two-channel 3-channel stereo
amplifier other than providing for
