Priority Lockout Mode (Factory default: “DISABLED”)
This mode is the opposite of “Whole House”. That is, when one is ENABLED, the other is DISABLED. When
ENABLED, if Zone 1 selects a source, Zone 1 will maintain exclusive control over that source until Zone 1
either selects another source or is turned OFF. Zones 2-4 can monitor the source, but cannot control that
source until released by Zone 1. Once Zone 1 has released the source, if the source is re-selected by one of
Zones 2-4, that zone will take control and will then also have priority.
IR Routing (Factory default: “ENABLED”)
This mode allows selective control of multiple same-brand same-model components such as multiple DVD
players or Satellite receivers. When “ROUTING ENABLE” is selected, IR commands are directed only to the
specific emitter output for the source selected in a zone, and not to the other source emitter outputs. When
“ROUTING DISABLE” is selected, IR commands are directed to all emitter outputs. The COMMON emitter
output will always output all IR commands.
Backlight Control (Factory default: 6 seconds)
This setting adjusts the duration that the Keypad LCD and Buttons will remain lit after a keypad button press.
Backlighting is variable from ‘always off’ to ‘always on’ or set to time out after 1 to 10 seconds in one second
increments. This setting will set the backlighting for ALL keypads in the system. IR codes generated by remote
controls do not activate backlighting.
1. Click “ALWAYS ON” to backlight a zone’s keypad(s) for as long as the zone is ON. Backlight turns off
when the zone is turned OFF. Useful in dark rooms.
2. Click “ALWAYS OFF” keypad(s) backlight will never turn on. Useful in rooms that are always brightly lit.
3. Click “TIMED” and use ‘Timed Backlight Control’ Pulldown Menu to set backlight duration from 1-10
seconds.
Monitor Lockout Mode (Factory default: “DISABLED”)
This mode can only be used if ‘Priority Lockout’ is selected. Checking the corresponding boxes prevents
sources from being monitored or controlled in specific zones. Example: If adult content is not to go to the
children’s areas this can be set at the time of system installation.
1. Select “PRIORITY LOCKOUT MODE” The Monitor Lockout boxes will be activated.
2. By Zone, click in the box of any Source that is not to be monitored in that zone.
Dynamic Monitor Lockout (Factory default: “DISABLED”)
This mode allows monitor lockout ‘on the fly’. There may be times when a source is generating program
material that can be made available to all zones/users. At other times this same source may be putting out
material that is not suitable for some zones/users. When the “ADMINISTRATOR” box is checked for a given
zone, for example, Zone 1, a special keypad command can block the audio and video for a given source from
being monitored by Zones 2-4 (Zones 2-8 in Expanded mode). When the special keypad command is issued a
second time, in Zone 1, that source is released and can then be selected and monitored by Zones 2-4 (Zones
2-8 in Expanded mode). That source remains under ‘priority control’ of Zone 1, until Zone 1 selects another
source or turns OFF.
1. Select “PRIORITY LOCKOUT MODE” The Monitor Lockout boxes will be activated.
2. Click the “ADMINISTRATOR” box for any zone that is to have ‘Dynamic Monitor Lockout’ ability.
3. After the project has been transferred to the MRC44 Controller, on a keypad in a zone with ‘Administrator’
control, simultaneously press the ”STATUS” and “SOURCE” buttons for the device to be ‘locked out’. If any
zone has that same source selected, the audio will mute and the video will go blank. A message: “Monitor
Locked” will appear on the keypad(s) in those zones.
4. To unlock, from the same zone with ‘Administrator’ control, simultaneously press ”STATUS” and “SOURCE”
again. If any zone has that same source selected, the message “Monitor Unlocked” will appear, however,
video and audio will not be routed to that zone until a source select button is pressed. A message: “Monitor
Unlocked” will appear on the keypad(s) in those zones. The ‘Administrator’ zone will retain priority until that
zone selects another source or turns OFF.
IR Output Intensity Settings
Emitter outputs 3, 4 and common have adjustable output levels to compensate for the varying IR sensitivities in
different branded products. The Low setting is equivalent to the emitter out on a 789-44 Connecting block (470
