Vmaz' Set Zone's Maximum Volume - Zektor HDA604 User Manual

beyond the noise level of any room, or the noise level of most amplifiers. Since adjusting the volume
below the noise level is just a waste of time, the minimum level allows you to limit the volume range.
Attempting to set the volume below the minimum level (using the 'VZ' command) will cause the Zek-
tor Switch go into full mute (no sound). When adjusting the volume upward from full mute, the vol-
ume will immediately jump to the minimum level.
The level is set in 0.5dB steps.
Command format:
^VMIZ @zone,@zone,minVol
^VMIZ @zone,+step$
^VMIZ @zone,-step$
^VMIZ @zone,@zone,?$
Response Strings:
^=VMIZ @zone,minvol$
Where:
= One (or more) zones to be affected.
@zone
= Minimum volume in 0.5dB steps with an offset of 200. Range is 0 to 'maxVol'-99.
minVol
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.
The minimum and maximum volume settings must have at least a 49.5dB (99 steps) difference
between them. Any attempt to set the minimum volume closer than 99 steps of the maximum, will
result in a setting of exactly 99 steps below the maximum volume setting.

'VMAZ' Set Zone's Maximum Volume

Each zone has a minimum and maximum volume setting.
The maximum prevents a user from overdriving the speakers, amplifier, or even the Zektor Switch
switch.
Setting the volume above the maximum level (using the 'VZ' command) is not allowed, and will be
limited to the maximum volume set by this command.
The level is set in 0.5dB steps.
Command format:
^VMAZ @zone,@zone,maxVol
^VMAZ @zone,+step$
^VMAZ @zone,-step$
^VMAZ @zone,@zone,?$
Response Strings:
^=VMAZ @zone,minvol$
Where:
= One (or more) zones to be affected.
@zone
maxVol = Minimum volume in 0.5dB steps with an offset of 200. Range is 'minVol'+99 - 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.
