14.3.2 ADJUSTING THE AUDIO OUTPUT LEVEL
The processed audio signal is available on the XLR OUT connectors.
The factory preset for the output signal is 0 dBm.
Where necessary, this output may be tuned using the Audio Module Setup / Output Level menu.
In order to best adjust the output level, we recommend enabling a pilot tone
, which identifies the maximum peak
which should match the deviation of 75 KHz. To do this:
1
Escape from the Output Level menu and enter the Output Mode menu.
2
Select the Peak Reference Tone option.
The Peak Tone identifies the maximum peak value of the audio reached by the processor while it is operating. This peak
corresponds to the maximum frequency deviation
. This allows you to set the levels for the entire sound chain simply and
safely.
The Peak Tone consists of a 500 Hz/ 0 dBm tone.
3
Once you have enabled the Peak Tone, adjust the Audio Output Level until You reach the desired
modulation deviation.
4
Select the Normal Operation option in the Output Mode menu
(Normal Operation mode allows a normal use of the equipment and all its functions)
NOTE: THE PROCESSOR FACTORY SETTINGS ARE 0 dB FOR BOTH INPUT AND OUTPUT.
TO ACHIEVE THE BEST AUDIO QUALITY, WE RECOMMEND NOT TO LOWER THE OUTPUT
LEVEL AND TO ADJUST THE EQUIPMENT CONNECTED TO THE PROCESSOR (STEREO
ENCODERS, EXCITERS, ETC.) RATHER THAN THE PROCESSOR ITSELF.
14.3.3 BYPASS MODE
In Processor ByPass mode (Audio Module Setup / Output Mode / Bypass Mode menu), all the processing
stages are disabled (AGC system, audio processing and pre-emphasis circuit). It allows you to carry out tests
and reference measurements: it is not intended for equipment setup or installation use
