The Redback A 4395A is a powerful 500 Watt mixer amplifier designed for installations that require a high-power zone amplifier. It is ideal for shopping centers, pedestrian precincts, public transport facilities, and convention centers.

This amplifier features two audio inputs: input 1 offers a balanced XLR Mic input or dual RCA line input, while input 2 provides a dual RCA input. Additionally, there is a music input on the front panel for connecting portable devices. When connected, this front input overrides the rear input 2 audio source and can be adjusted using the volume 2 level control.

The VOX circuit, with a 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 sensitivities. The amplifier also includes comprehensive protection circuitry, including overcurrent, overvoltage, and short circuit protection, ensuring reliable operation in any setting.
