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.

AV501HDXi
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.
Note: the loop output may be used to daisy chain several units together as is
typically done in store displays.
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.
