Q-MOS Stereo Power Amplifiers

Product Description

This 2U range of power amplifiers is intended for venues where amplifier racks are not on display, and once installed, are out of sight.  The Q-MOS range has all the same reliable attributes as the MA series but the twin VU bargraph and heavy duty laser-cut illuminated front panel and associated components have been removed.  The other components and power levels all remain the same as the MA Series.  These amplifiers are distinguished as a cost effective rack mount solution offering exceptional value for demanding applications where reliability is essential.
