Lifeforms 2+2 Mixer

the lifeforms 2+2 mixer is a low noise, ambidextrous four channel mixer for both audio and cv signals. the signal path is extremely versatile allowing it to function in five different configurations.

a four channel mixer
a pair of two channel mixers
four independent attenuators
two attenuators and a two channel mixer
one attenuator and a three channel mixer

the channel controls utilize a logarithmic volume curve tuned for audio signals but the module will work with cv as well. the diagram below illustrates the signal path of the 2+2 mixer. patching the output of channel 1 or 3 will remove it from the mixer circuit. patching the mix 1+2 output removes channels 1 and 2 from the mix (3+4) output and creates two, two channel mixers. channel 4 can not be removed from the mixer circuit, however if channel 1, 2, and 3 are all being used as attenuators, channel 4 is the only input remaining in the mixer allowing it to be used as a buffered attenuator.



controls:
in 1 jack - channel 1 input jack.
out 1 jack - channel 1 output jack. plugging in a cable removes channel 1 from the mixer and allows it to be used as a passive attenuator.
level 1 knob - channel 1 level attenuator.
in 2 jack - channel 2 input jack.
mix 1+2 out jack - channel 1 and 2 output jack. plugging in a cable removes channel 1 and 2 from the mix (3+3) output and allows channel 1 and 2 to act as separate a 2 channel mixer.
level 2 knob - channel 2 level attenuator.
in 3 jack - channel 3 input jack.
out 3 jack - channel 3 output jack. plugging in a cable removes channel 3 from the mixer and allows it to be used as a passive attenuator.
level 3 knob - channel 3 level attenuator.
in 4 jack - channel 4 input jack.
mix (3+4) out jack - main mixer output.
level 4 knob - channel 4 level attenuator.

specifications:
panel size: 8hp
depth: 24mm
power usage: +12v 7ma, -12v 7ma. does not require +5v. reversed power polarity protection.
