e MX300 lets you switch effect routings easily via front
panel controls, so you don’t have to spend time behind your
rack changing cables. Dual Mono sends the Left and Right input
signals through Effect 1 and Effect 2 respectively. Each signal
is then routed to its respective output, completely independent
from the other. Cascade (Series) sends Left and Right input
signals first through Effect 1, then through Effect 2, and then
routed as a stereo signal to their respective outputs.
Dual Stereo (Parallel) routes Left and Right input signals through
both effects independently. Both Effects’
output signals are then mixed
together, and routed to both
the outputs as a single stereo
signal.
Mono Split sends Left input
signal through Effect 1, while
the Right input signal is sent
through Effect 2. e output
signals of both Effects are then
mixed together, and routed to
both the outputs as a single
stereo signal.
Stereo routing provides a single
stereo effect path for Left and
Right signals. is routing
removes one of the effect
modules for users requiring a
streamlined signal path with
only a single effect for their
needs — but taking advantage
of all of the MX300’s process-
ing horsepower.
