Configuration register E (0x04)

6.5.1

Max power correction variable

6.5.2

Max power correction

Setting the MPC bit turns on special processing that corrects the STA333BW power device

at high power. This mode should lower the THD+N of a full DDX 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 will not effect channels 3 and 4, the

line-out channels.
