REFERENCE AMPLIFIER A500 User Manual 1. Introduction The A500 features special circuitry that protects your speakers from transients during start-up and your amp from overheating. The amp is not put at any risk even if there is a short on its outputs. Various operating modes, such as parallel and mono mode, open up different possibilities for effective implementation with the rest of your audio equipment, leaving little to be desired.

Connect the signal source whose output needs to be amplified. ◊ Please use only one of the three input connectors per channel at any one time! Here you will connect an output of your mixing console, your HiFi preamp or another signal source. Our rack mixing console EURORACK PRO RX1602, with its eight mono-usable balanced stereo channels, is an ideal choice for signal processing and source selection.

This results in a doubling of voltage, quadrupling of the peak power value and roughly trippling of the continuous power output on a single channel. The input and the gain control on channel 1 are used in mono-bridged mode. Thechannel 2 control elements are not used.
