Advanced Control
‘AUT’ Enable / Disable Auto Conversion of Analog / Digital Paths
Reserved.
‘MJP’ Enable / Disable Mute Volume Jump Option
When this bit is set to ‘0’ incrementing the volume of a muted zone will cause the zone’s volume to
increment from the current muted level. This is the “no surprises” mode of operation. If one person
mutes a zone and walks out of the room, someone else can walk into the room and pick up the volume
control and start adjusting the volume with no surprises. The volume will simply start increasing from
the current level.
When this bit is set to ‘1’ incrementing the volume of a muted zone will cause the zone’s volume to
jump back to its unmuted level before incrementing the level. This mode is most useful when only one
person is in control of the volume. For instance if the phone rings, the mute button can be pressed.
Once the call is over, pressing any volume button will cause the volume to jump back to it’s previous
setting. Since the same user pressed the mute button, he/she won’t be surprised when the volume
jumps back to its previous value.
The above behaviors are supported by the IR up/down commands, and the ‘+’ and ‘-’ options of the
serial / IP ‘VZ’ and ‘VPZ’ commands. Using the ‘VZ’ or ‘VPZ’ commands to set the volume directly
(leaving out the ‘+’ or ‘-’ characters), will not affect the mute setting.
‘UNV’ Unmute the Volume when a Volume Command is Given
Under the default mode of operation, using the ‘VZ’ or ‘VPZ’ commands to set the volume directly
(leaving out the ‘+’ or ‘-’ characters), will not affect the mute setting. This allows a muted zone to have
its volume set to a predetermined value, and then unmuted.
However control systems that use sliding touch pads will usually precalculate a volume, and send the
volume using the ‘VZ’ or ‘VPZ’ commands without the ‘+’ or ‘-’ characters. If the zone is muted, then
the commands will have no affect on the volume, until the zone is manually unmuted.
Setting this bit causes the zone to unmute whenever a ‘VZ’ or ‘VPZ’ command is sent, regardless of
whether it’s an incremental command or an absolute volume setting.
If the switch seems to be ignoring your control system’s volume slider, at times, you probably need to
set this bit.
‘SS’ Save Default Power On Settings
When all power is lost to the HDA800(V2) (for instance the power cord is unplugged), the current set-
tings will be lost. When power is restored all settings will be set to their initial values. This command
allows you to change those initial values.
To use this command, the HDA800(V2) should have there parameters to be saved, set to the values
that are to be used as the initial values.
Once the current settings are in place, this command is issued to save the current settings as the initial
values.
This command uses a bitmapped parameter to indicate which values are to be saved. A bit set to ‘1’
indicates the associated setting should be saved, a bit set to ‘0’ indicates the setting should not be saved
and the previously saved setting will remain unchanged.
