Front Panel Features
Section 2: Operation
1 Speakers
The speaker system is comprised of two mid-range speakers (left and right).
2 Audio Level Meters - 53-Segment Bargraph Displays
Audio levels for source channels 1-4 are displayed via these four high resolution 53-segment LED
bargraph meters (selected channels 1 and 2 on the left side of the front panel; channels 3 and 4 on the right
side). Ballistics for these meters are factory set to display a single floating PPM 'dot' above a VU bar;
each segment's color being fixed according to its position on the scale. Level gain is +4 dBu. Dynamic
range for these 53-segment meters is 65dB. For more information about the level meters, see page 18.
Contact the factory for additional meter information concerning meter scales and ballistics.
3 Phase Indication - Bi-color LEDs (Red/Green)
Two audio Phase Indication LEDs are provided; one above the left pair of level meters for showing phase
relationships between selected audio channels 1 and 2, and one above the right pair of level meters for
showing phase relationships between selected audio channels 3 and 4. Each LED indicates the
average
phase condition by glowing green for in-phase conditions, or red for out-of-phase conditions. While it is
normal for stereo signals to contain some intermittent instanateous out-of-phase and in-phase conditions
(flickering red), a steady red glow of the LED almost always indicates an out-of-phase alarm condition.
4 Video Source - 2-Position Rotary Switch
This two-position rotary switch selects one of two analog composite video signal sources input on the rear
panel BNC connectors (A or B). PAL or NTSC signals are automatically detected and configured for
monitoring. The video source selection is independant of the audio source selection.
5 Headphone Jack - 1/4" Phone 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. This jack accepts the standard 1/4” phone type stereo plug.
6 LCD Monitor Screen - TFT
View input video sources here. Select source inputs by setting the Video Source Selector Switch (Item 4)
to the desired input (A or B). Screen image parameters are adjustable by four manual controls (Item 7).
7 LCD Monitor Display Controls - Rotary Pots
Adjust the LCD monitor image with these four controls:
• BRIGHT
: Brightness; adjust for desired screen brightness.
• CHROMA
: Color Saturation; adjust for desired amount of image color saturation.
• TINT
: Tint; adjust for desired image color hue (NTCS only).
• CONTRAST
: Contrast; adjust for desired image scene dark-to-bright contrast.
