Hearing Helper™ Wireless FM Listening System System Overview Thank you for purchasing the Hearing Helper™ T800 transmitter from Williams Sound. This wide-band FM transmitter operates on the 863 MHz bandwidth and connects directly to your facility’s sound system; alternatively, it can used with a microphone as a stand-alone system. The T800 is designed for use with the optional R863 FM receiver to provide hearing assistance or language interpretation to a listening audience.

Hearing Helper™ Wireless FM Listening System Step 3: Connect the Audio Source On the back of the T800, two audio input jacks are available: an RCA-type jack for line-level, unbalanced audio sources; and a combo XLR (3-pin) and 1/4” TRS jack for connecting an unbalanced/balanced audio source. Note: Microphone must be dynamic (no phantom power supplied). If both inputs are used simultaneously, audio will be mixed. Connect the desired audio source to the T800 transmitter.
Hearing Helper™ Wireless FM Listening System Step 6: Adjust the audio Level Locate the “Gain Control” on the rear of the T800. With the audio source playing, rotate the “Gain Control” clockwise “+” to increase or counterclockwise “-” to decrease gain. Monitor the audio indicator “bars” on the display as you make your adjustments. As a general guideline: No audio indicator bars present = Audio source is TOO LOW.
