audio signal. The tone is helpful when conducting a sound check or for trou-
bleshooting the audio signal chain. The level of the tone is adjustable from
-60 dB to 0 dB and the frequency can be set to 400 Hz or 1000 Hz.

2. Set the frequency to 400 Hz or 1000 Hz.
3. Select Level and use the arrow buttons adjust the value between -60 dB

Matching Audio Levels with Offset
When linking two or more transmitters to a receiver, there may be a difference
in volume levels between microphones or instruments. If this occurs, use the
Offset function to match the audio levels and eliminate audible volume differ-
ences between transmitters. If using a single transmitter, set Offset to 0 dB.
1. Turn on the first transmitter and perform a sound check to test the audio
level. Turn off the transmitter when finished.
2. Turn on the second transmitter and perform a sound check to test the
audio level. Repeat for any additional transmitters.
3. If there is an audible difference in the sound level between the transmit-
ters, navigate to the Offset menu (Audio>Offset) in the transmitter to in-
crease or decrease the Offset in realtime to match the audio levels.
