Figure 4.6
The system pre-amplifier has a master and a music output that can be connected to 1 or 2 boosters for single or dual
channel operation. For single channel operation connect the Master output to the booster. The signal from the
booster must be returned to the 'Call in' (terminal) of the system pre-amplifier. For dual channel operation you must
also connect the Music output to a second booster. The signal from this booster must be returned to the 'Music in'
(terminal) of the system pre-amplifier.
