Designed as a high-performance, reliable means of re-clocking and distributing a 3G, HD or SD SDI source, the RB-VHDA8 offers eight outputs. Automatic input detection, re-clocking and cable equalisation of the input signal is provided, and the full range of SD and HD standards are supported by the unit allowing PAL and NTSC signals up to 1080p to be distributed. Each output is individually buffered providing separately driven outputs.
As well as an AC power input, the unit also has a 12V DC input for use, for example, in outside broadcast vehicles. Both power inputs may be connected, to give a dual-redundant power supply, where the supply providing the highest voltage will be used.
The front panel of the 1U rack-mounting case has only a single bi-colour LED which indicates amber to show power is present, then green should a valid incoming SDI signal be detected.
The rear has a single female BNC connector for the HD/SD-SDi input, and a further eight female BNC connectors for the outputs. A 2.5mm co-axial connector provides the DC power connection; a filtered IEC inlet, with adjacent fuse, is used for the AC power.
SMPTE-424M (3G-SDI), SMPTE-292M (HD-SDI), SMPTE-259M-AC1 (SD-SDI), SMPTE 344M (Other rates will be passed without re-clocking), DVB-ASI (Non inverted outputs only) at 270Mb/s.
