The RB-VHDA8 is a high performance, reliable eight way digital video distribution amplifier for re-clocking and distributing a 3G, HD (high definition) or SD (standard definition) SDI source to eight outputs. The unit provides automatic input detection, re-clocking and cable equalisation of the input signal to 100/350 meters (HD/SD) of coax cable.
The full range of 3G, SD and HD standards are supported by the unit allowing PAL and NTSC signals up to 1080p 60Hz to be distributed. Each output is individually buffered providing separately driven outputs for greater reliability. 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 can be used to give a dual redundant power supply; whichever voltage is higher will be used.
