Front Panel Features
• Headphone Jack (1/4” Connector): Select the headphone audio 
sources as you would for the internal speakers. When you plug in 
headphones, the internal or external speakers will mute.
• Tint (TNT): Turn this potentiometer to adjust the color hue of the 
video image (for NTSC signals only).
• Chroma (COL): Turn this potentiometer to adjust the color 
saturation of the video image. 
• Brightness (BRT): Turn this potentiometer to adjust the brightness 
of the video image.
• Contrast (CNT): Turn this potentiometer to adjust the contract of 
the video image.
• LCD Video (TFT): This screen displays input video sources.
• SDI Group Select (Push Button): This button selects the SDI group 
(1, 2, 3, or 4) for monitoring when 
Audio Source select button is set 
to SDI or set to Tracks Video, and SDI is the video source. One of the 
four LEDs will glow green to indicate the selected group.
• Audio Analog/AES Select (Push Button and Indication LEDs): 
These two push buttons, AUX 1 and AUX 2, toggle between the 
AES and analog (ANLG) inputs for the corresponding AUX 1 and 
AUX 2 input sections on the rear panel. When the analog input is 
selected, the LED is not lit. When the AES input is selected, the LED 
glows green.
• Balance (Rotary Potentiometer): This control pans the volume 
balance between the left and right speakers. If you adjust the 
balance hard to the left or right, the system retains a slight Left/ 
Right channel mix so phase discrepancies remain audible.
• Audio Source (Push Button and Indication LEDs): This push 
button steps through the four audio sources below: 
• SDI: Monitors the audio de-embedded from the SDI inputs 
on the rear panel.
• AUX 1: Monitors the audio input to the AUX 1 (analog or 
AES) inputs on the rear panel.
• AUX 2: Monitors the audio input to the AUX 2 (analog or 
AES) inputs on the rear panel.
