@zone
= Levels 0.5dB steps with offsets of 128 (128 = 0.0dB).
level
The levels in the commands are given in 0.5dB steps and use an offset of 128 to indicate a boost / cut
of 0.0dB. Values above 128 boost level by 0.5dB per step, for instance 129 = +0.5dB (a boost of
0.5dB), and 127 = -0.5dB (a cut of 0.5dB).
'BAZ' ('TRZ') Examples
Examples are only given for the bass command 'BAZ', for treble commands use 'TRZ' in the place of
'BAZ. The simplest form of the command is:
^BAZ @1,128$
and causes the bass level on zone '1' to be set to 0.0dB which is flat (no boost or cut).
The easiest way to use the volume on the HDA800(V2) is to know that 168 is full boost, and 88 is full
cut and every step from 88 to 168 boosts the bass level by 0.5dB, with 128 used to indicate no boost or
cut.
Or you can set a zone to an absolute level, in decibels, by taking the gain (which is positive for boost
and negative for cut), multiplying by 2 (to take into account the 0.5dB steps), adding 128, and using
that as the new level.
For instance if you wanted to boost bass by 9dB, you'd take the gain: 9dB multiply by 2 and add 200.
So 'level = 9*2 + 128 = 146', and:
^BAZ @1,146
would set the bass boost on zone 1 to 9.0dB.
You can also easily add or subtract from the current level in 0.5dB steps, for instance:
^BAZ @1,+6
^BAZ @3,-9
When using the '+' and '-' prefixes to add or subtract from current levels, the 'BAZ' command will
not allow you to go above 168 (+20.0dB) or below 88 (-20.0dB), though it's perfectly valid to send a
command that would attempt this.
