line signals from audio preamplifiers. Balanced signals are carried via a three way cable that connects all
three pins at each end of the interconnect cable.
AMPLIFIER CONFIGURATION SELECTOR (ACS)
The Amplifier Configuration Selector (ACS) is a unique switching method that exploits all of the
operational features of your Plinius SA-250 Power Amplifier. By using this switch it is possible to operate
your 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 high
fidelity system, then another SA-250 will be required for the other channel. This will provide an extremely
high performance option.
