"The highly renowned OMP/MF range of Mos-Fet power amplifier modules offers no compromise, high quality audio power at exceptionally realistic prices. All models are supplied as one complete built and tested unit.

These amplifiers are used both nationally and internationally by professionals in the leisure, disco, public address and studio industries, to name but a few, where they are well known for their quality, reliability and price/power/performance ratios. The OMP/MF series, whilst being the choice of the professional, is equally well suited to the domestic applications of discerning audiophiles. They have also successfully found a niche in industry and university research establishments

The OMP/MF range utilizes the latest Mos-Fet output devices, together with a sophisticated circuit design, both of which serves to achieve an enviable specification. These factors result in the exceptional clarity and realism which is essential to compliment today's high-technology sound equipment.

Realizing that reliability is of primary importance, generous power supplies are employed, incorporating a toroidal transformer. Glass fibre printed circuit boards are utilized, mounted on solid aluminium chassis with extensive heatsinking. These features, and many more, combined with rugged construction deliver a superlative level of reliability.
