No reset value.
LEV2
In order to obtain a signal level L (relative to the PCM maximum value) for generator 2
the value of LEV2 can be calculated according to the following formula:
Value range: [0x01..0x7F] = [-42.2dB..-0.07dB]
LEV1
In order to obtain a signal level L (relative to the PCM maximum value) for generator 1
the value of LEV1 can be calculated according to the following formula:
Value range: [0x01..0x7F] = [-42.2dB..-0.07dB]
15
No reset value.
ATT2
In order to obtain attenuation A the parameter ATT2 can be calculated by the formula:
Value range: [0x01..0x7F] = [42.2dB..0.07dB] and [0x81..0xFF] = [60.2dB..18.1dB]
ATT1
In order to obtain attenuation A the parameter ATT1 can be calculated by the formula:
Value range: [0x01..0x7F] = [42.2dB..0.07dB] and [0x81..0xFF] = [60.2dB..18.1dB]
