| SCAA010 - BALBOX Serial to Composite with 2 o/p Audio Extraction. |
Converts an SDI signal to analogue composite video for mnitoring and extracts and converts one embedded stereo pair. A reclocked SDI output is provided, along with two composite outputs. Analogue audio is output on two XLR’s.
INPUT
Input signal: 270 Mb/s serial NRZI to SMPTE RP259M and EBU Tech 3267 with digital audio
embedded to SMPTE 272M-AC (synchronous audio at 48kHz)
Input equalisation: automatic up to 250m of Belden 8281 cable or similar
SDI OUTPUT
Output: 270 Mb/s serial NRZI to SMPTE RP259M and EBU Tech 3267
Output level: 800mVp-p +/-20mV across 75ohm termination
COMPOSITE OUTPUT
Output: 625/50 PAL or 525/60 NTSC automatic switching
Output level: 1.0Vp-p +/-7mV across 75ohm termination
Frequency Response: +/-0.25dB to 5.5MHz
ANALOGUE AUDIO OUTPUTS
Number of outputs: Two (one for each mono or half of the stereo pair within the selected AES/EBU signal)
Output: Electronically balanced
