Table 18. AutoMode EQ Settings
By setting AMEQ to any setting other than 00 enables AutoMode EQ. When set, biquads 1-4 are not user
programmable. Any coefficient settings for these biquads will be ignored. Also when AutoMode EQ is used
the pre-scale value for channels 1-6 becomes hard-set to -18dB, dependent upon the value of AMPS
