If no argument is supplied to the command, the default value is assumed. The configuration is
saved immediately. See the Audio Overview section for more information.
If +WDGR is set to +12dB gain, the +CLVL command cannot add any more positive gain. Setting
the +CLVL command to +12dB gain would not yield a total of +24dB gain, since the gain stage
can only supply a maximum of +12dB gain.
The following formulas govern the total digital receive gain:
Total Gain = (WDGR Gain + CLVL Gain)
-84dB <= Total Gain <= +12dB
This command sets the 8 Ohm speaker driver gain of the current audio path. Note from the
diagram at the top of this section that only the Analog 2 audio path has a speaker driver. Setting
the speaker driver gain on other audio paths has no effect.

The +CLVL gain value is added onto the +WDGR gain. Depending on the gain
setting of +WDGR, the full range of the +CLVL command may not be realized.
