1 Introduction
Demon 2 is a de-embedding monitor designed for applications requiring the simultaneous
monitoring of video and embedded audio that can convert incoming SDI with embedded
audio into combinations of component, composite, Y/C and SDI distribution, along with
20 bit AES and analogue audio.
The on-board 12-bit monitoring video encoder can be configured to produce a variety of
video outputs. The four output formats available from the encoder are GBR with sync on
all, YUV with sync on Y, S-video and composite in either 625 line or 525. A combination
of these outputs will be available depending on Mode and rear module selection.
Demon 2 de-embedding monitor
Analogue video outputs may also be substituted for up to four non-reclocked SDI input
loop-throughs.
Any one of the four audio groups contained in the SDI stream can be de-embedded and
the resulting four channels of audio then be routed to any of the four audio outputs.
The output audio is available simultaneously as four mono (two stereo) balanced analogue
and two balanced or unbalanced AES, depending on the rear module. Audio monitoring is
available via the mini headphone socket located on the front board edge.
Sixteen presets allow you to store and recall parameters such as video output
configurations, audio routing and audio group selection.
Crystal Vision Introduction
Demon 2 User Manual R1.4 407/09/2012
Demon 2 uses the same sophisticated techniques employed in TANDEM to protect and
minimise the effects of cuts to untimed and asynchronous SDI, SDI corruption and TRS
loss in the SDI signal. The Demon 2 will also report a frozen or black video input and
EDH errors.
The main features are as follows:
SDI audio/video monitoring encoder
Up to five simultaneous video outputs – RGB, YUV, Y/C, Composite and SDI
depending on rear module and link selection.
Automatic 525/625 input switching
Video error detection and alarm
Sophisticated error handling of upstream input switching
Simultaneous analogue and AES/EBU audio outputs from any one incoming embedded
audio group
4 x 4 audio router to select any de-embedded channel to any output
Dedicated headphone monitoring socket
Flexible yet simple remote control and/or board edge control
Sixteen presets recallable by GPIs and Demon control
Demon 2 is a 100mm x 266mm module, which fits in all standard frames and can be
integrated with any boards from the company’s full product range.
Demon 2 can be used with the RM04, RM05, RM06, RM22 and RM36 frame rear
modules, depending on the packing density and outputs required. SDI input loop-
through/analogue video outputs are selected by movable links on the board.
Demon 2 is particularly ideal for multi-channel broadcasters faced with many embedded
feeds to monitor, or for applications needing to de-embed both analogue and digital audio
at the same time. Demon 2 can also be incorporated with an Indigo DT desktop box to
drive a plasma or CRT display and active speakers for local audio de-embedding and
extraction of analogue video.

2Hardware installation
The Demon 2 single height module can be used with the RM04, RM05, RM06, RM22
and RM36 rear connectors that will fit into all Crystal Vision rack frames (RM05 – not
1U frames). All modules can be connected or removed while the frame is powered,
without damaging the board.

Changing sync level
The output sync can be changed from the default of 300mV to approximately 2V for
component modes that require large syncs with board link PL10. Place PL10 in the upper
position for 2V and the lower position for 300mV.
Selecting SDI/analogue outputs
On rear connectors that support O/P 2, O/P 3, O/P 4 or O/P 5, either SDI or analogue
video can be selected for each output with link pairs as shown in the link position
summary table above. Output 1 is always Analogue and cannot be configured for SDI.
Adjusting analogue gains
The following gain adjustments are provided:
Variables
P5 & 6 Analogue Video calibrate (factory set, not user adjustable)
P1 O/P 1 calibrate (factory set for 1.0V)
P2 O/P 2 calibrate (factory set for 1.0V)
P3 O/P 4 calibrate (factory set for 1.0V)
P4 O/P 3 calibrate (factory set for 1.0V)
P8 Analogue Audio Channel 2 Gain (factory set for =18dBu)
P9 Analogue Audio Channel 2 Gain (factory set for =18dBu)
P10 Analogue Audio Channel 3 Gain (factory set for =18dBu)
P11 Analogue Audio Channel 4 Gain (factory set for =18dBu)
Note: All gains have been factory set and should not require any further adjustment.

2.2 Rear modules and signal I/O
The Indigo 4 4U frame takes up to 24 single height Crystal Vision modules, 12 single
height modules will fit in the Indigo 2 2U frame, six single height modules will fit in the
Indigo 1 1U frame and two will fit in the Indigo DT desk top box.
There are five types of rear connector available for the Indigo frames to provide system
flexibility by allowing a mix between access to all connections and maximum module
packing density.
