Product Description

These multi-purpose amplifiers are constructed using solid-state dual-mono amplifiers plus a single stereo headphone channel combined into one module allowing either pre-amp drive or headphone listening. ZAX Amps unleash the bass and fidelity held captive in your music and transform headphones into the instruments they were meant to be, significantly enriching your listening experience. The PreAmp and Speaker amplifier circuits feed separate right (ch1) and left (ch2) outputs for maintaining channel separation and optimizing the power to each secondary amp circuit. They are configured in differential bridged mode format eliminating the need for output coupling capacitors, maximizing power efficiency, and providing unattenuated full audio bandwidth. These high efficiency circuits make an excellent pre-amp servo for coupling portable audio devices to stationary amplification equipment. Additionally, due to the outstanding circuit efficiency, they can be used stand-alone to transform low power audio devices into systems capable of driving most full size speakers to a level of 85-90db SPL.
