Adjusting Pilot Tone loss Threshold Settings
The coarse tone loss threshold setting is adjusted using S1 for input A and S2 for input B.
S1/S2
Value
1
-12dB
2
-6dB
3
-3dB
4
-1.5dB
5
-0.5dB
6
+0.5dB
The threshold set with all switches off is -20dB; the table shows the additional threshold
values for each switch. To calculate the required switch setting, always subtract 20dB from
the total configuration value.
Example
To obtain a threshold of -35dBu, set levers 1 (-12dB) and 3 (-3dB), this gives an effective
level threshold of -35dB (-15dB -20dB). The -20dB adjustment is only subtracted once for
each input.
Note:
It is recommended to use the fine control accessible through the front panel for accurate
calibration.
