The SIGNAL SWITCH module is a “MUTE” module composed of two independent stages, depending on the position of a jumper located at the rear (2x mono or 1x stereo).
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” and outgoing “OUT” signal can be muted by activating a selector.

ON = selector up, the incoming signal is directed to the output and therefore remains audible, a yellow LED lights up.
MUTE = selector down, incoming signal is muted. The use of “vactrol” avoids an unpleasant click and brings a slight OUT fade (the LED goes out).

Internal routing (normalization) is a passive multiple of input 1:
The incoming signal on input 1 is also routed to output 2 (which retains its own “MUTE” function). Inserting a jack into input 2 breaks the downstream routing. This allows different combinations for its use, depending on your needs.

Other option:
A jumper at the back allows the module to be split, either:

• in two independent stages for two mono signals (mode A)
• in one stage for a stereo signal (mode B). Thus, input 1 becomes the L channel and input 2 the R channel (same for the OUTs). The input 1 selector controls both channels (LEDs indicate the status of both channels).
