The SIGNAL SWITCH STEREO module continues the variation of the “SIGNAL SWITCH” module (“MUTE” module), this time with a module dedicated to stereo signals.
Using quality ‘vactrols’ helps avoid annoying clicks when turning your signals on/off through the module, and adds an interesting fade out. The MUTE of the signals is therefore clean and discreet.

Explanations:
An incoming “IN” L&R and outgoing “OUT” L&R stereo signal can be muted by the activation of a single illuminated push button.

ON = Button pressed, blue LED lit, the incoming stereo signal is routed to the output and therefore remains audible.
MUTE = Button off, the incoming stereo signal is muted. The use of “vactrol” avoids an unpleasant click and brings a slight fade OUT.

The internal routing (normalization) is a passive multiple, per channel, of the 1L&R inputs:
The incoming signal on input 1L is also routed to the other 3 outputs 2L to 4L which retain their own “MUTE” function. Inserting a jack into one of the inputs (2 to 4) breaks the downstream routing. This allows different combinations for its use, depending on your needs. Same for the R channel.

Trick ! You can hijack this mode to invert the routings: stereo signals entering OUTs 1, 2, 3 & 4 can be routed to IN 1 (Attention, only activate one stage at a time, the module is not a mix!).

Two jumpers at the rear (corresponding to the two L&R channels) allow the module to be split into two independent stages:
Thus, the signal entering the 1L input is also routed to the 2L output (which retains its own “MUTE” function). Inserting a jack into the 2L input breaks the downstream routing. Same for the R channel.
AND
The signal entering the 3L input is also routed to the 4L output (which retains its own “MUTE” function). Inserting a jack into the 4L input breaks the downstream routing. Same for the R channel.
