The RB-VHDA2x4 is a high performance, reliable dual input and eight output digital video distribution amplifier for re-clocking and distributing up to two 3G, HD (high definition) or SD (standard definition) SDI sources.
By default, the RB-VHDA2x4 acts as two independent video distribution amplifiers, with input 1 routed to outputs 1-4 and input 2 routed to outputs 5-8. Either input can also be routed to all outputs if desired which can be selected by the Input Select switch on the front panel or via the built-in webserver. The webserver also provides status information for the unit.
The unit provides automatic input detection, re-clocking and cable equalisation of the input signals 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.
