The following is a main of the
mixer-6 Ch circuit. The circuit constituted by six input channels. The
channels are from monophonic channels CH 1-4 and CH 5-6, are intended
for stereo use. The number of input channels they want as long Itself
Can Increase You Want.
Skema mixer 6 channel The
output of Each channel drives the RV1-6, that regulation potesometer
level of sound. With RV7-12 We create conditions of balance Between two
channels (BALANCE). All the signals from the input channels in this
point are added by two adders [IC1a-b], for Each channel Here exist two
Trimmer TR1-2 That adjust the gain of Each IC, adapting the level of
signal of the output, in the level That We Want. They Can be suppressed
if you do not need something and Standard and Poor. The next stage is a
,
three bands of regulation. The IC3α-b, constitute the output of the
mixer, they want a one acre have gain and they want the make the
essential isolation of the previous stages, with the unit That We Will
drives. For whoever they want want they want use headphones, it exists
a classic circuit drive of headphones, round the IC2a-b, that give the
output in the JF13. It Can Also Also exist optical clue of audio
levels, with a stereo VUMETER.
