Amp’s control connecting

The SW1 to SW4 outputs are used to control an amp by its footswitch input. Depending on the features of

your amp they can be used for switching channels, switching on/off reverb or effects loop, BOOST function

or other.

SW1&2 and SW3&4 outputs’ circuit diagram is shown below.

SW1 to SW4 lit indicators mean short-cutting of the adequate relay’s contacts (latching type). This circuit is

separated from the rest of the MGC-6 circuits. It is recommended to use connectors with plastic shielding

to avoid incidental connection with a signal grounding. Lot of amps are equipped with such type of a foot-

switch input so if your amp is equipped with footswitch input connector you should contact your dealer or

the manufacturer of your amp to settle if such type of connection is possible to apply. Depending on an

amp model this connection have to be done using mono or stereo Jack/Jack cable, Y type cable (stereo

Jack – 2 x mono Jack) or need dedicated cable or adapter offered by G LAB. The actual list of available

cables and adapters you’ll find at 

www.glab.com.pl

 If you don’t find on our site the cable you need please

AUX connectors

MGC-6 has four  AUX connectors for additional modules to extend the controller’s functionality e.g.

AUX A/B SWITCH or AUX 2xLOOP. The actual list of modules you’ll find in accessories for the controller

at 

www.glab.com.pl

.

Single AUX output circuit diagram is shown below.

AUX 2xLOOP connection

AUX 2xLOOP enables controlling by MGC-6 two additional effect loops connected for e.g. to an amp

effects loop or between OUT output and amp input. Looper has passive signal path and true bypass circuit

for switched off effects.

Connection of the devices should be done by using the cable supplied to the AUX 2 x LOOP. With this

cable we connect AUX IN connector of the AUX 2xLOOP with one of the  AUX1-4 connectors of the MGC-
