Audio and Video Changeover Unit
The 1U Rack Mounting “2×1”(Emergency) Changeover Selector Unit has been designed around ultra-reliable, wide-band relays to provide an economic means of switching up to three input signals between two output circuits, or visa versa, either locally, or from a remote location. The design is capable of handling SDI/Analogue Video, Analogue Audio signals, plus RS422 control in any combination to suite individual appliances.
Features:
- 1U Frame
- Modular
- Switches; Audio/RS422/SDI
- Self Contained or Remote Control
This versatility also enables the unit to be used in other sections of the transmission chain such as backup on-air VTR’s where the RS422 changeover option is available.
The operational control of the Changeover Unit can either be remote via 9 pin “D”socket mounted on the rear of the panel, or locally from a three-position switch mounted on the front panel. The control circuit is “looped”via a “D”sockets which also enables more than one Changeover Selector to be used on the same control circuit.
The unit comprises of a 1U card frame which accommodates up to three 2×1 switches and a power supply.
