The Proton DJ Series Amplifiers are the equivalent of an iron fist in a velvet glove. The main attraction of the DJ Series is its over 97% reliability and the excellent tonal quality, no mean feat considering the compact size and superb power to weight ratio. These amplifiers are equipped with independent sweepable high and low pass filters on each channel so you can optimize output for subwoofer or full range systems to provide peak audio quality and performance from any speaker system you may be using. The popular DJ801 offers 800W + 800W RMS @ 4 Ohms, and the DJ501 follows its success with 500W + 500W RMS @ 4 Ohms, to give the user more choice based on which model suits their needs. Very good savings are realized with a unique added feature – the built-in crossover to make the amplifier a subwoofer amplifier or a midhighs amplifier, besides being a full range device of course, thereby eliminating the need for external crossovers and simultaneously ensuring, easy, no complication, safe operation even if a novice is handling the setup. All these features coupled with the extremely competent pricing, makes the DJ Series the natural choice for the discerning audio professionals.
