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.
