Noise Gate Attenuation
Reports the current noise gate attenuation.
000 = 0dB
001 = 1dB
010 = 2dB
011 = 3dB to 5dB
100 = 6dB to 7dB
101 = 8dB to 9dB
110 = 10dB to 11dB
111 = 12dB
AGC Gain
Reports the current AGC gain setting.
AGC/Noise Gate Signal Source
Determines which ADC channel the AGC and noise gates analyze. Gain is adjusted on
both channels regardless of the AGCSRC setting.
0 = Left ADC output
1 = Maximum of either the left or right ADC output
AGC Release Time
Defined as the duration from start to finish of gain increase in the region shown in Figure
12. Release times are longer for low AGC threshold levels.
000 = 78ms
001 = 156ms
010 = 312ms
011 = 625ms
100 = 1.25s
101 = 2.5s
110 = 5s
111 = 10s
