Amp should be set to AUX.
Plug audio jack from amp into audio-technica receiver. The port is on the bottom labelled monitor out.
The receiver is capable of receiving two mic transmissions. To turn the receiver on, slide the top EXT-OFF-1-BOTH to the right one click for one transceiver or two clicks to the right for two transceivers.
To turn on the 'mics' (audio-technica transmitter), press the top power/mute button until the unit comes on.
The receiver and transmitters will stay on the shelf under the table-top to protect them from getting damaged.
At the end-of-the-Expedition they will be returned to the Imaging Office.
