librate[0]>...
<outCalibrate[7]>
<speechVol> <si-
deTone>
Response
TA sets loudspeaker path parameters
OK.
Parameter
<outBbcGain>
Setting for DAC gain amplifier attenuation
(0 ≡ 6 dB, 7 ≡ 15 dB, 8 steps of 3 dB)
0(0x0)-7(0x7)
<outCalibrate[0]>
<outCalibrate[7]>
Multiplication factor for output samples
Attenuation = 20 * log (outCalibrate[n] / 32768)
(0(0x0)- 65535(0xFFFF)
<speechVol>
Setting of actual volume;
0(0x0)-7(0x7)
<sideTone> Multiplication factor determining how much of the original
microphone signal is added to the earpiece signal.
Side tone gain/dB = 20 * log (sidetone/32768)
0(00x0)-65535(0xFFFF)
Reference Note
Set command only works in audio mode 3.
