60 HDA800(V2) Serial Protocol, Version 1.3, 9/12/13
Audio Control
Command format:
^GAZ @ zone,@zone,gain Set the gain of a zone or zones.
^GAZ @ zone,+step$ Add ‘step’ number of 0.5dB steps to current gain.
^GAZ @ zone,-step$ Subtract ‘step’ number of 0.5dB steps from current gain.
^GAZ ?$ In polled mode, reads current settings of all gain changes.
^GAZ @ zone,@zone,?$ Read current gain settings of given zone(s).
Response Strings:
^=GAZ @ zone,gain$
Where:
@ zone = One (or more) zones to be affected.
gain = Gain in 0.5dB steps with an offset of 200. Range is 152 to 248.
The gain command is given in 0.5dB steps and uses an offset of 200 to indicate a gain of 0.0dB. Values
above 200 raise gain, and values below 200 lower gain.
‘GAI’ Set Input’s Gain (Input Trimming)
Each input has a gain level that can be set from -24dB to +24dB. The gain control allows you to match
the volume levels of each input to the different levels of each source. This allows volume settings to
sound the same, when switching between source devices with different output levels.
Input gain is set in 0.5dB steps.
Command format:
^GAI @ input,@input,gain Set the gain of a input or inputs.
^GAI @ input,+step$ Add ‘step’ number of 0.5dB steps to current input.
^GAI @ input,-step$ Subtract ‘step’ number of 0.5dB steps from current input.
^GAI ?$ In polled mode, reads current settings of all input changes.
^GAI @ input,@input,?$ Read current gain settings of given input(s).
Response Strings:
^=GAZ @ input,gain$
Where:
@ input = One (or more) inputs to be affected.
gain = Gain in 0.5dB steps with an offset of 200. Range is 152 to 248.
The gain command is given in 0.5dB steps and uses an offset of 200 to indicate a gain of 0.0dB. Values
above 200 raise gain, and values below 200 lower gain.
‘BAZ’, ‘TRZ’ Set Zone’s Bass and Treble Levels
Each zone has a Bass and Treble level that can range from -20.0dB to +20.0dB. Interaction between
the Bass and Treble controls and the 5 Band Equalizer settings are limited to a +/-20.0dB range. Add-
ing a boost of +20.0dB to the Bass setting as well as the EQA or EQB equalizer bands, will not result
in a +40.0dB, but will be limited to +20.0dB.
The levels are set in -0.5dB steps.
