The APG20 is a receiver gateway, designed to be used in combination with the Wall LineInput (WLI) and Wall Microphone Input (WMI) flush mount wall input units. It converts the signal transmitted over UTP CAT5 cabling into signals corresponding Line andMicrophone levels, and makes them available on RCA and XLR connectors. The maximum distance that can be covered between the input unit and the receiver gatewayis 300 m. By applying a ARJ03P junction box halfway the cabling, which provides the requiredpower supply for the input units, the maximum distance can be extended to 600 meters.
