Max power correction
Setting the MPC bit turns on special processing that corrects the STA380WS power device
at high power. This mode lowers the THD+N of a full FFX system at maximum power output
and slightly below. If enabled, MPC is operational in all output modes except tapered
(OM[1:0] = 01) and binary. When OCFG = 00, MPC does not affect channels 3 and 4, the
line-out channels.
Noise-shaper bandwidth selection
AM mode enable
The STA380WS features an FFX processing mode that minimizes the amount of noise
generated in the frequency range of AM radio. This mode is intended for use when FFX is
operating in a device with an active AM tuner. The SNR of the FFX processing is reduced to
approximately 83 dB in this mode, which is still greater than the SNR of AM radio.
