The Redback A 4395A 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 Mic 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 Mic XLR on input 1, and both RCA inputs 1 and 2 have adjustable input sensitives. The amplifier has a host of protection circuitry including over current, over voltage and short circuit protection.
