Active re-amplifier with two outputs allowing the engineer to play a pre-recorded track back through guitar amplifiers and pedals. The re-amp employs a unique class-A circuit design that has been optimized for use with guitars. Features include balanced line level input with LED peak indicator and level control, class-A circuit topology for optimal reach and frequency response, a transformer isolated output to eliminate hum and buzz caused by ground loops, a 180o polarity reverse switch to bring both amps into phase, and a dual ground lift switch for noise-free operation. Reamping works equally well on bass, keyboards, drums and voice. The X-Amp is built like a tank to provide years of trouble-free performance. The dimensions are 50 x 140 x 89 mm and the weight 907 g.
