5.7. EQ Settings
Perform EQ settings (ON/OFF, Band number, Gain, Q and Center frequency) of the input/output channels. 9000Series Amplifier responds with the same data as that received. Band number, Gain, Q, and Center frequency cannot be received when EQ is set to OFF. They can be valid only when EQ is set to ON.
Note: Command cannot be received during power off.
