Front Panel Features
When
CVBS
1
or
2
is selected, one of the two corresponding CVBS
inputs on the rear panel is selected for monitoring. See the
Audio
Select
button (
page 14
) for information about selecting audio
inputs with video monitoring. Note that the selected CVBS LED will
glow green when selected.
•
Channel Indicators
(LEDs, 1 through 4): These four LEDs (1, 2, 3,
and 4) indicate when the associated channel is assigned to one or
both speakers. When these LEDs glow green, the channel is
assigned to the left speaker, when amber, the right speaker. When it
alternates between green and amber, the channel is assigned to both
speakers. The LEDs are not lit when the channel is not assigned to
either speaker.
•
Level Meters
(53-Segment Bar Graph): These high-resolution, LED
bar graph meters display audio levels for metered audio signals.
Ballistics for these meters are factory set to display a single floating
PPM dot above a VU bar; each segment’s color is fixed according to
its position on the scale. Reference level is +4 dBu. Dynamic range
for these meters is 66 dB.
•
Phase
(Bi-Color Red/Green LED): The audio phase indicator
shows the phase relationships between audio channels A (1) and B
(2). The 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
instantaneous out-of-phase and in-phase conditions (flickering red)
a steady red glow of the phase indicator almost always indicates an
out-of-phase alarm condition.
•
Speaker Select
(Push Button): This switch routes the audio signal
to either the internal speakers or to external speakers connected to
the terminal posts on the rear panel.
•
SDI Signal Lock
(LED): When the monitor receives a valid and
locked SDI video signal, this LED lights green.
•
SDI Select (SEL)
(Push Button and LED Indicators): This control
selects one of two inputs, HD/SD-SDI (MDA model) or SD-SDI
source (SDA model) for monitoring when either the
Video Source
select button or the
Audio Source
select button is set to SDI. When
the SDI 1 source is selected for monitoring, the LED will not be lit.
When the SDI 2 source is selected, the LED indicator will glow
green.
