AMPLIFIER CONFIGURATION SELECTOR (ACS)
The Amplifier Configuration Selector (ACS) is a unique switching method that exploits all
of the operation features of this amplifier. By using this switch it is possible to operate
this amplifier with either balanced or unbalanced signals and achieve a stereo or mono
output.
Stereo or Mono use of this amplifier will depend on the type of ancillary equipment
employed with your system. If you wish to use this amplifier as a single channel (mono)
power amplifier in a stereo Hi Fi system, then another amplifier the same as this will be
required for the other channel. This will provide an extremely high performance option.
STEREO.
This SA-50 is a dual channel or stereo amplifier.
Both left channel and right channel signals are amplified and output to a stereo pair of
loudspeakers. This is the most common use of this amplifier.
MONO.
Using the built in switching facility (ACS) both channels of this amplifier
combine (electronically) to form one single amplifier channel. Special input and output
wiring requirements apply and are explained throughout this manual.
Balanced or unbalanced input options will depend on the type of signal available from
your preamplifier or other equipment.
The SA-50 provides both options to allow you to choose the most suitable preamplifier
for your purpose.
Plinius preamplifiers offer both balanced and unbalanced output options.
BALANCED LINE
is normally used to transmit signals in a professional environment.
Because balanced line effectively reduces or eliminates noise pickup by the cabling, it has
become increasingly more important in high quality domestic HiFi systems.
