Crystal Vision
Specification
Audio Processing
Audio Delay Adjustable audio delay of up to 400ms on each channel. Delay is either
on or off for any given channel.
Store presets and control via the card, frame active front panel, remote
panel and VisionWeb.
Audio Replace Routing of input audio together with audio from up to four de-embedded
groups present on video input to any channel of up to four output
embedder groups. HANC cleaning means that there is no remnant of
the original version of old groups. If group 1 is replaced there is not an
old group 1 with the “mark for deletion” flag set. Instead there is just the
new modified group 1.
Audio Processing Gain level adjustment on each channel b18dB and -18dB in
0.1dB steps with 0dB calibration.
Mute.
Stereo to mono conversion.
Auxiliary data Auxiliary data passed unless set to blank.
Status monitoring
LEDs Front of card edge LED indicators to indicate:
PSU rails present.
SDI input HD/SD for both channels.
Input audio groups 1 and 2 present for both channels.
GPI inputs
Number and type: 4 x GPI inputs. Recall of presets.
Active pull to ground, pulled up to +5V through 7 kohm.
Pulse mode GPI to be asserted for min. of 40mS and at least 2mS
before vertical interval.
GPI outputs
Number and type: 2 x GPI outputs (one per channel), assignable to any of 35 alarm
conditions such as loss of input, audio missing and audio channel
silence (<-63dBFS
).
Electrically: Open collector transistors 30V, 270 ohm current limit
resistors. Pulled up to +5V through 7 kohm.
Input fail output
Type: Black.
Control
Local: Intuitive board edge interface with two select buttons, shaft encoder and
ten character alphanumeric display.
Remote: Control from frame active front panel and remote panel.
VisionWeb Control is available via the web server on the frame and
allows operation using a standard web browser on a PC or tablet.
Statesman Lite allows control from any PC on a network.
SNMP control and monitoring via frame CPU and Ethernet connection.
