Eq1Z', 'Eq2Z', 'Eq3Z', 'Eq4Z', 'Eq5Z' Set The 5 Band Equalizers' Levels - Zektor HDA604 User Manual

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 Zektor Switch 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.

'EQ1Z', 'EQ2Z', 'EQ3Z', 'EQ4Z', 'EQ5Z' Set the 5 Band Equalizers' levels

Each zone has a 5 Band Equalizer associated with it, each of the five bands have levels that range from
-20.0dB to +20.0dB. Interaction between the Bass and Treble controls and the 5 Band Equalizer set-
tings are limited to a +/-20.0dB range. Adding 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.
The band center frequencies for each command are:
EQ1Z -
EQ2Z -
EQ3Z -
EQ4Z -
EQ5Z -
Only the 'EQ1Z' command will be described, all the bands use identical syntax.
Command format:
^EQ1Z @zone,@zone,level
^EQ1Z @zone,+step$
^EQ1Z @zone,-step$
^EQ1Z @zone,@zone,?$
Response String:
