3. Detailed description of the invention The present invention relates to mode control second
setting of non-emergence type stereo amplifier, and its purpose is σ, by using one side of human
power as the signal 1 j 婢 signal of mode switching, stereo main amplifier The mode switch is a
stereo mode state 1 \ 1 channel, 1 channel 'banner 〃 人 manual power n η 1 even if the left
and right power of the stereo main amplifier can be obtained even if the point tic 4 H − Ru. In
the conventional stereo amplifier, in the fall spring of the stereo mode, if V1 is added to the sum
channel hole, if the force is added to the sum channel hole, then the exit blade is also only on the
left side, and 7) h still tin, hence mono-7 / L If you do not switch to / mode, 晋 tTA-: u + jVC 、 中,

source. い1. If it is assumed that the input 16 'is added only to the human-car child (1) and the
input terminal (1' lvc moves and there is no 1g issue), the human-power beat (11 input signals
are increased to the level of the circuit (61 at Ifri # level -1, transistor 1) and the base of 1 is
stopped at the base of lijfM, 'ti, child t1J7J] (7) Step 1111 is turned on, and the transistor fill's
collector output σ m + mm nat 'j JII is driven to the level of the foot, and -2 left-hand drive force

Therefore, since the input terminal V is distributed and supplied to the output terminal + 4 ++ 41

father. 1) In the process of receiving 4 stereos, the input terminal (1) has an eccentricity with an
equal bell, and the input and terminal (the 48th level of 11 has become 0 level Because there is 1

is transmitted to one cylinder) is timed according to a time number of C / and p /. H91 / (-4,-can
be selected in the m-V valve to be loaded. Since the transistor 171 'is turned on when the bias is
applied again, the position of the drain sensor (-of the transistor +7 (the result of the reduction of
the transistor -7 is rapidly reduced to 1 and responds to human power' ¥ 5) . In the case of stereo
paternity, even if the human power No. 48 of the 1 ° 11 channel is temporarily lost, it will be
held in the condition that there is a W-force r input signal of 8113 Ill in one field. -Switch switch
