Front Panel Features
• Mix (LEDs, Left and Right): When the left and/or right Speaker 
Assign
 button is pushed a fifth time, its associated Mix LED glows 
green to indicate that channels can be added to that speaker mix 
(Mix Mode) by pushing the Mix Assign Buttons located under the 
level meters. 
• Mix Assign (Buttons, 1 through 4): Each of these four push buttons is 
separately associated with one of each of the four lever meters (1, 2, 
3, or 4). Each button is used to assign the channel monitored by the 
associated level meter to the left or right speaker mix only when 
both the left and right speaker assign buttons are in “Mix Mode” 
(the 5th push button in the cycle. Refer to *** for details.) When in 
mix mode the right and/or left Mix LEDs will glow. When a 
channel is selected using these buttons, the channel LED above the 
corresponding level meter will glow green when assigned to the left 
speaker, amber when assigned to the right speaker, and alternate 
between green and amber when assigned to both speakers.
• Volume (Rotary Potentiometer): This knob controls the loudness of 
the audio reproduced by the internal speakers, external speakers, or 
connected headphone.
• Video Source (Push Button and LEDs): This button selects one of 
three signal sources for monitoring: SDI, CVBS 1, or CVBS 2. 
Repeatedly pressing the source select button steps through each of 
the three selections. One of the three indication LEDs (SDI, CVBS 1, 
or CVBS 2) will glow to indicate the selected signal source.
When SDI is selected, you can select one of the two available SDI 
inputs on the rear panel for monitoring using the SDI Select 
button. Note that the SDI LED will glow green if the selected SDI 
signal is locked, or red if the signal is unlocked.
