Front Panel Functions The front of the Plinius Reference A-150 power amplifier incorporates all the facilities you will require on a daily basis. 1. DISPLAY LED An LED in the centre of the front panel indicates the power is on. When first switched on, the display will vary in brightness until the initialisation sequence is completed, after which the LED remains lit. - Page 8 This feature allows you to leave the Reference A-150 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.

Page 9: Rear Panel Functions
1. INPUT TERMINALS Input terminals for your Plinius Reference A-150 power amplifier are easily accessible and fitted near the top centre area of the rear panel. RCA INPUTS: These standard RCA terminals are for use with unbalanced signals from most signal sources such as audio preamplifiers. - Page 10 Unbalanced leads such as single ended, RCA or coaxial are common and are used in the majority of audio signal systems. The terminal plug and socket are most commonly called RCA and can be found on your Plinius Reference A-150 for use as the standard input terminals for both left and right inputs.
- Page 11 In order to integrate more effectively into a home theatre or multimedia system, the Plinius Reference A-150 has a remote trigger socket on the rear panel. By connecting a preamplifier or processor with a remote trigger output signal to these terminals, the Reference A-150 can be put in and out of Class AB/Mute by the component to which it is connected.
