Installation / Operation Instructions
Unpack the amplifier and power supply from the box. Place the amplifier in a dry location,
usually behind the shelf where the monitors are located.
The unit has integrated mounting brackets that are pre-drilled in case the user wishes to
screw the unit to the shelf (screws supplied by user).
Connect the source device outputs to the appropriate input jacks on the AV501HDXi.
Connect cabling from the AV501HDXi outputs to the desired display or recording device.
The loop output may be used as normal or connect to the next distribution amplifier to
create more outputs.
Insert the power supply connector into the power jack of the AV501HDXi. Plug the wall
transformer into a 120Vac outlet. The power LED should be on and the unit is ready to
use.
This unit is very effective in breaking AC ground loops that cause moving video hum bars.
If a system using non-isolated distribution amplifiers is exhibiting hum bars, place the
AV501HDXi between the video source and the first distribution amplifier. This should
eliminate or greatly reduce visible hum bars. Larger display systems may contain more
than one AC ground loop, and require more than one isolated input amplifier to totally
eliminate the issue.

This unit 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.
