Siemens MC55 AT manual Atsnfo Set audio output = loudspeaker path parameter, Atsnfo=?, Atsnfo?

17.13AT^SNFO Set audio output (= loudspeaker path) parameter

AT^SNFO controls the earpiece path amplification. The read and write commands refer to the active audio mode. The write command works only in audio modes 2 to 6.

Parameter Description

<outBbcGain>(num)(^SNFW)

Negative DAC gain (attenuation) adjustable in four 6 dB steps from 0 dB to -18 dB (0=0 dB, 3=-18 dB) 0...3

<outCalibrate>(num)(^SNFW)

Formula to calculate the value of the 5 volume steps selectable with parameter <outStep>: Attenuation = 20 * log (2 * outCalibrate[n] / 32768)

0...32767

<outStep>(num)

Volume steps 0 - 4, each defined with outCalibrate[n] 0...[4]

<sideTone>(num)(^SNFW)

Multiplication factor for the sidetone gain.

Formula to calculate how much of the original microphone signal is added to the earpiece signal: Sidetone gain in dB = 20 * log (sideTone / 32768).

0...32767
