INPUT TERMINALS

Input terminals for your Plinius SA-250 Power Amplifier are easily accessible and fitted to the top centre area of the rear panel. A brief summary of connection possibilities is listed below, while a more detailed explanation follows later in this instruction manual.

RCA INPUTS LEFT & RIGHT: These standard RCA terminals are for use with unbalanced signals from most signal sources such as audio preamplifiers.

XLR BALANCED INPUTS LEFT & RIGHT: XLR connectors fitted to this amplifier are for use with balanced 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.
