CONNECTING AUDIO EQUIPMENT
The NET4001A provides an audio channel via the audio in and out jacks.
1.
Connect a pre-amplified microphone to the Audio In jack on the transmitter and/or receiver.
2.
Connect a loudspeaker to the Audio Out jack on the transmitter and/or receiver.
The audio signals are transmitted bi-directionally and simultaneously with the video signals. This allows control of a loudspeaker or door
intercom system, for example, at the monitored location. Bi-directional audio applies to box-to-box connectors only. MPEG2 should be
selected in order to receive a good audio signal.
