IC Audio AMP 120 Bedienungsanleitung Seite 30

9.3 Operation of several power amplifiers on one audio
source
Generally amplifiers can be connected individually to one
audio source or can be configurated in a
MASTER/SLAVE arrangement. The difference is to have
one level control only in the master unit for all amplifiers
in the MASTER/SLAVE-configuration. The SLAVE units'
level controls here are out of order.
If the units are operated single ("STAND ALONE"), levels
can be controlled individually for each unit of course.
The operating mode can be set up by the internal
jumpers SW403 and SW404 – see drawing above and
adjacent table.
Factory setting is STAND ALONE.
