location, usually behind the shelf where the monitors are located.
The unit has integrated mounting brackets that are predrilled 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 CHO4053.
Connect cabling from the CHO4053 outputs to the desired display or recording device.
The loop-thru 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 CHO4053.
Plug the wall transformer into a power outlet.
The power LED should be on and the unit is ready to use.
