A-A4377 – REDBACK PHASE 4 PUBLIC ADDRESS AMPLIFIER 125W 4 INPUT

PRODUCT DESCRIPTION

Specifically designed for applications requiring up to three microphone inputs, without compromising output power and overall performance. The A-A4375A features three inputs which can be configured for either microphone or line level operation. A-A4375A conservatively delivers 125WRMS power. Frequency response extends from 50 Hz to 15 kHz ±3 dB at a total harmonic distortion (THD) of less than 0.5% @ 1kHz. Vox muting is provided on inputs one and two, which, when activated, automatically mutes the other inputs. Bass/treble controls and phantom powering capability enable unparalleled flexibility for a wide scope of applications such as factories, workshops, mine sites, sports clubs and office buildings. Operates from 240 volt AC mains or 24 volt DC permitting battery backup operation during mains power failure. Output can be 100 volt line, 70 volt line or low impedance (4 – 16 Ω) loads. Thermal overload, over-current/load protection circuitry and fuses on both AC and DC provide excellent fault condition protection and robust performance. Tape output sockets are provided for recording purposes or feeding into additional power amplifiers.
