Cable equalisation >200m Belden 8281 or equivalent
Auto or manual 625/525 line selection
Automatic de-embedding of SMPTE or Sony format
Video input is 8 bit processed for 10 bit output DACs

ANALOGUE VIDEO OUTPUTS
Maximum of five video outputs (depending on rear module) which can be combination of analogue (RGB, YUV, Y/C, composite) and SDI
RM04 allows six different output combinations, RM05 and RM06 allow 12 combinations, and RM22 allows 12 combinations

COMPONENT VIDEO PERFORMANCE
YUV and RGB into 75ohm. Y and G 1 volt with syncs. U/V and R/B 700mV +/-2%
RGB sync: 300mV sync with no burst
Frequency Response:
Luminance: +/-0.2dB to 5.5MHz
Chrominance: +/-0.2dB to 2.5MHz
Noise: <-60dB weighted luminance or chrominance
Gain Error: <1%

COMPOSITE VIDEO PERFORMANCE
Frequency Response:
Luminance: +/-0.2dB to 5MHz
Chrominance: +/-0.2dB to 2.5MHz
Noise: <-54dB weighted luminance or chrominance
Differential Gain: 2% typ.
Differential Phase: +/-0.5% typ.
Blanking: VBI blanking on or off. PAL lines 6 to 22 and 318 to 335. NTSC lines 10 to 20 and 272 to 283. Conforms to standard digital decompression dimensions and does not process digital input data for the active analogue video half lines

AUDIO OUTPUTS

GPI INPUTS
4 x GPI allowing the recall of 15 presets

GPI OUTPUTS
2 x GPI for loss of video and audio silence

AUDIO PROTECTION IN DE-EMBEDDER
A variety of sophisticated techniques are employed to protect and minimise the effects of cuts to untimed and asynchronous SDI, SDI corruption and TRS loss in the SDI signal
