Primarily designed for use in bars and restaurants, where separate control of the music in several areas is required, these designs may be applicable for use in any situation where a number of low-power amplifiers are required, such as for cue-feeds, effects-loudspeakers, museum displays etc.

Three models are available; each combines four separate low-impedance amplifiers in a single 2U rack-mounted case. Each amplifier has an individual, XLR/A-gauge jack combination balanced input connector, a level-control with associated signal-present and clip LED’s, and binding-post speaker terminals. An input-selector switch allows each pair of amplifiers to be driven either separately, with inputs in parallel, or bridged into mono. Both models are fan-cooled with circuit-protection and turn-on delay.
