<TUNING> menu
This menu can be entered by pushing .
In this menu channel/group and frequencies can be setup.
The name of the group is shown on the top right of the display.
SYNC group is a quick self-settable channel synchronized by
receiver (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 <
SEL > 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)
<AUDIO> menu
In the AUDIO menu are shown all the audio parameters (this menu can be entered by pushing ).
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: applies different audio HP filter: Flat/ 60Hz/
80Hz/ 120Hz/ 170Hz/ 250Hz/ 400Hz.
The third <AUDIO> menu allows to set the noise reduction and
setup the limiter:
- MTB40S supports 2 different type of “Companding systems”:
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).
-
Limiter: if is set “On”, an input audio signal above the peak
threshold (
up to 30 dB above peak ) is not cut but attenuate,
without lost quality. The limiter acts as a variable attenuator
(thanks to the feedback system), maintaining a distortion
<3%. When the limiter intervenes, the front led turns blue.
If this parameter is set “Off”, the limiter is disable.
