Response
OK
TA resets the parameters currently selected in audio modes 2 – 6 to their
factory values.
The restored values are: <inBbcGain>, <inCalibrate>, <outBbcGain>,
<outCalibrate[0 to 4]>, <sideTone>.
<outStep> is not be reset to its default. Instead, the current value will be
retained when the ME is powered down with AT^SMSO or restarted with
AT+CFUN=1,1.

Response
TA sets microphone path amplifying.
OK
Parameters
Setting for ADC gain Amplifier 0 - 7 (0=0dB, 7=42dB,
<inBbcGain>
8 steps of 6 dB)
Multiplication factor 0 – 32767 for input samples
<inCalibrate>
attenuation=20*log (inCalibrate/32767)
Note
· The read and write commands refer to the active audio mode.
· The write command works only in audio modes 2 to 6.
· The range of <inCalibrate> is up to 65535 but will be suppressed to
32767. Values above <inCalibrate> = 65535 will cause a failure.
· Changed values need to be stored with AT^SNFW for use after
restart.
· Attention! When you adjust the audio parameters avoid exceeding the
maximum allowed level. Bear in mind that exposure to excessive
levels of noise can cause physical damage to users!
