Specifically designed for applications requiring up to three microphone inputs, without compromising output power and overall performance. Each model features three inputs which can be configured for either microphone or line level operation. A 4375 and A 4385 conservatively deliver 125W and 250W RMS power respectively. Frequency response extends from 50Hz to 15kHz ±3dB 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 240V AC mains or 24V DC permitting battery backup operation during mains power failure. Output can be 100V line, 70V line or low impedance (4 - 16O) loads. Thermal overload, overcurrent/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.
