| 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 Impedance: <75ohm Output level: 18/24dBuFS – user selectable THD: <0.007% Noise: <-74dBu (idle channel) Output Connectors: XLR-style male
CONTROLS AES audio mute: DIP switch (position 1) Analogue output level: DIP switch (position 2) Audio selection: Rotary switch, positions 0-7, selecting groups 1-4 and analogue outputs 1-8
INDICATORS Tri-colour status LED: Red: no SDI input Orange: SDI present – no embedded audio detected Green: SDI present – embedded audio detected
INSTALLATION DATA Package: Standard BALBOX housing, with two ¡®XLR¡¯ male and two 75ohm BNC connectors 184 x 103 x 42.4mm. Weight: 950g. Mains supply: 90 – 250Vac Consumption: <10VA |
