Description
Silence override
0 = No override. Audio DAC silence switch setting depends on the
silence detector circuit and or on the master_mute status.
1 = Override. The Audio DAC silence switch is activated.
Switch between ‘flat’ (for the Digital Amplifier) or ‘compensate’
correction filter curve (for the Audio DAC).
0 = Curve for Audio DAC
1 = Curve for Digital Power Amp
Select the polarity of the DATA to the Audio DAC = a means to
control the output signal polarity. The DC and AC dither which
must be added to the noise-shaper input will NOT be inverted
when inverting the audio data.
0 = Non inverting data out
1 = Inverting data out
The number of ‘zero’ samples counted before the silence detector
signals whether there has been digital silence:
00 = 3200 samples
01 = 4800 samples
10 = 9600 samples
11 = 19200 samples
This is an overriding quickmute on the master channel which
mutes the interpolator output signal in 32 samples, using the
cosine roll-off coefficients.This overrides the soft mute.
0 = Quick mute is off
1 = Quick mute on
Mute function via micro controller interface:
0 = Soft mute mode which takes 32x32 samples to mute
1 = Quick mute mode
1 = Power on for audio DAC
0 = Power off for audio DAC
