(with SYNC group, on the top right of the display is shown the name
of the synchronized receiver).
Use the selector to change values (<+/->) and <click> to confirm.

Using quick channel setup buttons (<CH>), it is possible to enter
quickly in the tuning menu. Note that the menu has a different
layout (see the side image)

The sensitivity of the audio input is settable between “AF Gain”
(measured in dB) or “AF Level” (measured in dBu).

To help proper audio gain setting, an audio bar is supplied (with
maximum peak indicator) indicating the headroom to audio peak
(0 dB , nominal deviation 40KHz). Set the gain, with the maximum

input signal, avoiding the peak on the audio bar.

TRY TO SETUP TO HAVE A MAX PEAK HOLD BAR CLOSE TO -6dB.

Using quick gain setup buttons (<GAIN>), it is possible to enter
quickly in the audio gain menu. Note that the menu has a different
layout (see the side image)

The second <AUDIO> menu allows to set:

- audio phase (0° or 180°)

- High Pass filter (Flat, 60, 80, 120, 170, 250, 400 Hz)

The third <AUDIO> menu allows to set the noise reduction:

 ENR-Wisy: designed for maximum noise reduction
 ENC-Wisy: designed for maximum audio fidelity (use this in

case of special vocal application or to remote instruments)

RF power can be setup to 10mW, 50 mW or 100mW (depending
