Adjusting the transmitter gain

The sensitivity of the transmitter microphones can be adjusted using the gain control. It can be set on the transmitter itself, provided the transmitter is not connected to the receiver. When the transmitter is connected, this feature is disabled and controlled by the receiver.

Note:

Once the transmitter and receiver are connected, the gain can be adjusted via the transmitter menu on the receiver (see Accessing the transmitter menu, navigating through menu items and making settings).

To adjust the gain on the transmitter:

When the receiver is powered on, press the ON/OFF button twice in quick succession to enter gain mode.
Pressing one more time changes the gain in three steps from -6, to 0 to +6 dB. The green feedback LEDs indicate the selected setting (see Meaning of the LEDs on the transmitter).
After a short time, the last selected value is saved and the transmitter returns to normal operating mode.
