Audio Authority CMX-144 User Manual 9
Operation
1. Front Panel Keys.
The front panel is operated by touching the sensitive “key” areas: POWER, SOURCE, and DIM.
• Touch POWER to turn the unit on or off (low power mode).
• Each time you touch a SOURCE key, the CMX-144 switches to the next available source.
• Any restricted zones are skipped (if source 1 is restricted other zones select source 2, 3, 4, and then back to 2).
• The power button puts the unit in “low power mode”. Wake the unit by sending any valid IR command, web
interface command, serial command, or touching the POWER key.
• Touch the DIM key to change the front panel indicator brightness. Three levels of brightness and off are avail-
able. The POWER button dims in off mode, but does not turn off completely except in low power mode.
2. Model 1106 Remote Control.
The 1106 enables all functions of the front panel including discrete on and off. Note:
if the CMX-144 receives an IR command via the rear panel IR input,
the front panel IR receiver is automatically
disabled
until power is manually removed from the unit or the IR is reset via serial or Ethernet. (See Appendix A).
• Press OFF to enter standby mode.
• Press any key to wake the unit from standby mode.
• Press a ZONE key and then a SOURCE key to switch sources. The other zone indicators dim while source
selection is taking place. If the ZONE key is pressed again, the selection is cancelled. If a SOURCE key is
pressed without first pressing a ZONE key, the unit does not switch sources.
• The zone stays active for 10 seconds after the ZONE key is pressed. If no source key is pressed, the unit
returns to a neutral state. The user must press a ZONE key to switch sources.
Advanced Operation Behavior
Controlling the CMX-144 via serial, Ethernet, or IR controllers enables all basic functions above, plus the advanced
features listed below. Note that new settings are saved every 30 seconds. If the unit is powered off before the 30 second
auto-save, those settings will be lost when the unit powers on. Use the manual save command [S] to save after making
permanent changes.
1. Lockout (Source Restriction).
• Any user can “lockout” other zones from viewing the currently selected source.
• When a user sends a lockout command, the video blinks once to indicate that lockout has been implemented.
• If any other zones are viewing the source when it becomes locked, they are switched to the next allowed
source.
• The source remains locked to the zone for five hours or until that user cancels the lockout.
• When an attempt is made to view the locked source from front panel controls or graphical web interface, the
CMX-144 skips the locked source and selects the next allowed source.
• When a source is restricted while in breakaway mode (see breakaway audio switching below), the audio is
matched to the video of the source. Example: if zone 1 selects input 1
video
and input 2
audio
, and then sends
a lockout command, the CMX-144 switches to input 1
audio and video
and locks out other zones.
• When a user tries to select a restricted source via serial or Ethernet, the component video blinks once and the
feedback string (RESTR) is returned on the serial port.
2. Breakaway Audio Switching.
Audio and video switched independently. See Appendix A.
• Advanced control methods can switch audio independent of video. Example: the user is watching a sports
event (Source 1, satellite TV) and wants to listen to radio coverage (Source 2, internet radio).
• If the CMX-144 is used with composite video, the composite signals will always be routed with the audio
because composite video must be connected via the digital coax pathways. See Appendix D for details.
• The CMX-144 can be used with both component and composite video, using the Breakaway switching feature
to control Component and composite video signals separately, enabling the CMX-144 to behave as two 4x4
video matrix switchers. See Appendix D for details.
