Audio Subsystem Overview
The audio sub-system block diagram below indicates where the various gains and AT commands take effect.
Since the AT command values are saved separately for each audio path, the audio gains should be tuned
independently for each audio path. Note that the +CLVL is intended to operate like a volume control, so it should
be set to 0dB gain during the tuning process (this is the default value).
Tuning Audio
Note: PCM digital voice is not supported in the Multi-Tech models.
Audio parameters need to be set for each device connected to the audio sub-system. The audio parameters are
saved independently for the three audio paths: Analog 1 and Analog 2. Tune the audio parameters using the
procedures detailed below.

Analog
1. Select the relevant audio path, and issue the AT+VIP command the set the audio parameters to their
2. Set +MGE so that the microphone output plus MGE gain is 23dB to 25dB below 2.828Vpp.
3. Make a voice call.
4. Adjust +VGT to appropriate levels.
5. Adjust +VGR to appropriate levels.
6. Adjust +WSDG, if applicable.
