The AV501HDXi incorporates isolation circuitry on the input connectors that helps to eliminate AC hum bars associated with ground loops. The ground connection on the inputs is isolated by a high impedance that effectively breaks the AC ground loops.
The AV501HDXi has one set of inputs and five sets of outputs (Output #5 is designated as the loop output, but may be used to drive a monitor directly). The unit allows any Audio/Video source, with Y, Cb, Cr, or Y, Pb, Pr Outputs (component), to distribute Audio and Video to five different locations without any signal loss. The amplifier also supports composite video and digital audio.
