AMPLIFIER FEATURES – FRONT PANEL

FRONT PANEL LAYOUT SHOWING MUTE AND BIAS SWITCHES

MUTE SWITCH

It is not recommended practice to interfere with the input cables while the amplifier is switched on and

connected to the loudspeakers, so a Mute button is fitted to interrupt the input signal. This allows you to

connect and disconnect the input cables without the necessity of turning the amplifier off.

When the amplifier powers up from start, the Mute automatically closes and has to be switched for normal

listening. Press the button once to open the mute, and again to close it. The mute also disconnects the

speakers while the LED is on.

CLASS A SWITCH

This switch on the right of the panel alters the operating bias of the amplifier. Press once to activate Class

A, and again for Class AB. In Class A the LED is ON. Either mode may be used for listening, with Class A

preferred.

CLASS AB: This position reduces the bias on the output stage to operate the amplifier in Class AB. This

is a bias configuration used by the majority of high fidelity amplifiers. In Class AB your Plinius SA-103

produces very high quality sound, suitable for all occasions where ‘super critical’ listening is not a

priority. The quality of performance in this mode may exceed that of many other amplifiers so a dual

benefit exists in that this facility provides the user with a much cooler operating temperature, and a much

reduced demand on electricity particularly at idle (while the amplifier is not reproducing music). This

unique feature allows you to leave the Plinius SA-103 switched ON at all times, rendering the amplifier

ready for use and requiring only a few minutes of warm-up in Class A before the very best of the

amplifier's sonic qualities may be experienced.
