The sound source should come directly from the system mixer or amplifier as an unprocessed signal. NOTE: If using a Williams Sound MIC 044 headset microphone with a 3.5mm plug, you MUST use it with a WCA 083 electret adapter. The T35 will not supply simplex (phantom) power through the 1/4” jack without an adapter. -

If tuned too close to the transmitter, with a strong signal, the most accurate tuning of the receiver is not possible. -
