4 channel Amplifier

Top end brand 

60w at 4 ohm


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.
