The X-Amp 500 is an active Re-amp device that interfaces the balanced line-level output from professional recording systems with guitar effects and amplifiers. Two active buffered high impedance outputs with active level controls connect to effect pedals and instrument amplifiers. Each output is transformer isolated to eliminate hum and buzz caused by ground loops. Output-2 includes polarity invert for achieving proper phase alignment between two amps. When installed in a Workhorse 500 series rack the user has access to the Omniport connector. The X-Amp’s Omniport is configured as an instrument preamp allowing a guitar to connect and drive the amplifier outputs.
