23 SETUP OF DISCRETE (L & R) AUDIO OUTPUT
23.1 ANALOG OUTPUT LEVEL
You can adjust the analog audio output level (XLR connectors) through the Output Level control:
DEFAULT SCREEN
OUTPUT CALIBRATION menu
OUTPUT LEVEL page
The Output Level parameter expresses the peak
value (in dBu) achieved by the audio output signal (which therefore
corresponds to the maximum
frequency deviation).
To set the optimum audio output level, it is advisable to enable the Peak Reference Tone. The Peak Tone is a 400-Hz
reference tone that identifies the peak value of the audio signal, which must match the maximum frequency deviation of
75KHz. In other words, the peak tone identifies an audio level (expressed in dBu) that will never be exceeded during
normal processor operation.
To enable / disable the Peak Tone:
DEFAULT SCREEN
OUTPUT CALIBRATION menu
OUTPUT MODE menu
PEAK REFERENCE TONE / NORMAL MODE
NOTE: The processor factory settings are 0 dB for both input and output. To achieve the best degree of evenness, we
therefore recommend adjusting the equipment connected to the processor (stereo encoders, exciters, etc.) rather than
the processor itself.
We remind you that pre-emphasis may be disabled on the outputs, although it is not recommended.
- Where there are long sections of cable and unbalanced connections, we recommend setting the output level to
above 0dB to compensate for possible attenuation by the cables.
- The peak output value is the same as the Output Level parameter only for processed musical signals, which are
dynamic and constantly variable. For static (sine) signals, the output peak is attenuated by a few dB
compared to the
Output Level shown on the display; the exact degree of attenuation depends on the curve selected.
23.2 DIGITAL AUDIO OUTPUT LEVEL
The digital audio output can not be altered by the user.
23.3 NOISE GATE SETTING (NOISE GATE)
The Noise Gate function allows you to avoid the effects of background noises while the input signal presents a lack of
high frequencies. The parameter to be set is the Noise Gate Threshold, which determines the threshold value below
which the dynamic pre-emphasis is automatically excluded. Noise Gate Threshold may be adjusted within a range of –
80 to –51dB (1 dB steps). The Noise Gate function can be turned off if necessary by turning the shuttle counter-
clockwise to the Off position. The default level is –76dB
