7.2.2.10 Auset
Audio settings: channels activation and level adjusting.
Figure 7-24
MONO/L
audio level setting for the MONO input channel (left for the stereo
version). It can be set with 1 dB steps between -13 and +14 dBm. If this
parameter is set to X dBm, the exciter generates 75 kHz modulation for
X dBm input
MPX/R
audio level setting for the MONO input channel (left for the stereo
version). It can be set with 1 dB steps between -13 and +14 dBm.. The
meaning is the same of MONO/L
MONO/L
software switch to activate/deactivate the MONO channel (left for the
stereo version)
MPX/R
software switch to activate/deactivate the MPX channel (right for the
stereo version)
When the exciter is in STEREO mode (BdSet menu), the levels on both channels
are forced to the same value
7.2.2.11 IAMLC
Intelligent Automatic Modulation Level Control.
Figure 7-25
The IAMLC functionality provided by PTX-LCD adjusts the modulation level by
adaptation of the input level, without the use of limitation or compression.
When the average modulation level surpasses the maximum threshold for a time
interval exceeding the maximum hysteresis time that has been set, the input level
is attenuated by 1 dB. In the same way, when the average modulation level goes
below the minimum threshold for a time interval exceeding the minimum hysteresis
time that has been set, the input level is increased by 1 dB.
