1. INTRODUCTION

Audiophile Circuits League. -GATE MIX is a 4 channel Audio signal mixer,

consisting two 2-in-1 mixers (1+2 & 3+4), whose outputs are summed together

to the master output. All 4 channels can be switched ON/OFF controlled by

switches and/or gate or even CV signals. Further there is an AUX-input, which is

routed unity gain (no attenuator) to the SUM. The logic of switching the signals

on and off can be negated (inverted), meaning a high control signal could switch

the signal on (gate=on) - or the opposite behaviour; a high control signal could

switch the signal off (gate=mute).

So you can always switch the channels on and off using the switch, by just

�lipping the channel s state (on or off). No disturbing clicks or glitches should be

heard when switching an audio input signal on and off due to a fast „slew

ramping" takes place in the circuit, controlling the amplitude of the signal when

switched on and off.

Each Channel got a LED which is lighting up, when the channel is switched on, so

ll it let a audio input signal going through to the outputs.
