The SA-4200™ amplifier’s inputs are configurable for two modes of operation, and its outputs for two modes of
operation.
INPUT MODES
The channel inputs can be connected in three different ways to achieve the following modes of operation.
Dual-Dual Mono Mode
For Dual-Dual Mono operation, all four channels operate independently of each other, with their input
attenuators controlling each respective input level. As a result, a signal at the input of channel A produces
an amplified signal at the output of channel A. Likewise, a signal at the input of channel B produces an
amplified signal at the output of channel B, and so on. The loudspeaker load is connected to the amplifier
output terminals matching the positive loudspeaker connection with the positive output terminal. Likewise,
the negative loudspeaker connection is matched with the negative output terminal. See OUTPUT MODES
below.
