Scheme and signal path description
M2L has true passive signal path (without signal boosting and buffering
elements). Owing to this the M2L doesn’t influence the guitar tone (doesn’t
change the tone and doesn’t cut the signal). It is recommended to use the
M2L to "exclude" from the effects’ signal path the effects without true bypass
function. Controlling by MIDI provide galvanic separation from controlling
device. It is recommended to use 9V DC from separated source. Every time
after switching on the power supply both effect loops are switched off and the
signal path is “opened”.
Manual loops switching
To manual loops switching there are used two buttons signed LOOP1
and LOOP2. To switch on/off the loop press corresponding button.
MIDI channel setting
To set the MIDI channel use the rotatable knob signed as MIDI
CHANNEL. To switch the channel use the small screwdriver to turn smoothly
central part of the switcher to the right or to the left. The arrow-head indicates
set channel (letter A, B, C, D, E, F correspond successively with the channel
numbers 10, 11, 12, 13, 14, 15, and number 0 indicates channel 16).
Controlling via MIDI commands
M2L can by controlled by Program Change commands. DS1 micro switch
serves to choose the digit in Program Change commands that should be
considered by the M2L.
DS1=ON – received is the decimal digit of program number (units’ digit
is ignored)
