The Redback A 4395 is a 500 Watt Mixer amplifier for installations requiring a high power zone amplifier. Ideally suited for use in shopping centres, pedestrian precincts, public transport facilities and convention centres.

The amplifier has two audio inputs, with input 1 either a balanced XLR input or dual RCA line input, and input 2 a dual RCA. There is also a music input on the front of the amplifier for connection of portable devices. This input when connected, over-rides the rear input 2 audio source and is adjusted via the volume 2 level control.

A VOX circuit with front panel sensitivity adjustment, allows input 1 to mute input 2. Phantom power (15 volts) is available at the 3 pin XLR on input 1 and both inputs 1 and 2 have adjustable input sensitivies. The amplifier has a host of protection circuitry including over current, over voltage and short circuit protection.
