Noise Gate Configuration & Misc. (Address 1Fh)
Noise Gate Channel Gang (NG_ALL)
Default: 0
0 - Disabled
1 - Enabled
Function:
Gangs the noise gate function for channel A and B. When enabled, both channels must fall below the thresh-
old setting for the noise gate attenuation to take effect.
Noise Gate Enable (NG_EN)
Default: 0
0 - Disabled
1 - Enabled
Function:
Enables the noise gate. Maximum attenuation is relative to all gain settings applied.
Noise Gate Boost (NG_BOOST) and Threshold (THRESH[3:0])
Default: 000
Function:
Sets the threshold level of the noise gate. Input signals below the threshold level will be attenuated to -96
dB. NG_BOOST = ‘1’b adds 30 dB to the threshold settings.
Noise Gate Delay Timing (NGDELAY[1:0])
Default: 00
00 - 50 ms
01 - 100 ms
10 - 150 ms
11 - 200 ms
Function:
Sets the delay time before the noise gate attacks. Noise gate attenuation is dictated by the SOFTx &
ZCROSS bit settings unless the disable bit for each function is enabled.
