Effectivement il est mentionné dans la notice de ne pas connecter les sorties switchs sur les amplis Mesa Boogie.

5.2 Amp channel / function switching:
SW1-6 OUTs are used for controlling the amp channels as well as other functions, e.g. the amp’s built-in reverb.
G LAB consults with amp manufacturers in regards to their proprietary wiring of amp controlling/switching. Information can be found in our website
www.glab.com.pl which explains how to control a given amp model and what cable or adapter is required. Many amps are equipped with a 1⁄4’ female Jack( footswitch input). If your amp is equipped with such type of connector, please check on
www.glab.com.pl or ask your dealer and amp manufacturer if it is possible to connect and control your amp directly (with mono or stereo Jack/Jack or Y type cable) by using relay outputs.
Warning! DO NOT CONNECT THE SW1&2, SW 3&4 and SW5&6 OUTPUTS TO THE EXTERNAL SWITCHING INPUTS OF THE MESA BOOGIE AMPS. To control these types of amps use G LAB MIDI AMP CONTROLLER MAC-4.4 (product code 00876). The diagram below indicates the layout connections of the SW1&2, SW3&4 and SW5&6 outputs.
