7.9 AUTOMODE REGISTERS

7.9.1

Table 18. AutoMode EQ

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 1-2 becomes hard-set to –18dB.
