using
quick channel setup
buttons (<
ch
>).
In this menu current
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).
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>
In the AUDIO menu are shown all the audio parameters.
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)
Audio phase
: 0° or 180°
Note:
Since common "2-wires + bias" microphones invert the phase, when the MIC mode of the
transmitter is set to “ bias”, the phase is automatically inverted and so the complete system
(MTPxx+MIC) has 0° phase (an asterisk appear on the display near the phase to indicate that the
phase was inverted).
High Pass Filter
: applies different audio HP filter: Flat/ 60Hz/ 80Hz/ 120Hz/ 170Hz/ 250Hz/ 400Hz.
Noise reduction
:
JNR-Wisy: designed for maximum noise reduction
JNC-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
