The 8 x 4 HD/SDI Video Routing Switcher with Stereo Audio from Link Electronics is designed to handle high-resolution HD/SDI video. It manages analog video and stereo audio inputs, accepting 8 inputs and providing 4 outputs. The switcher features a modular design that offers flexibility to the users by adding other modules later to the unit, allowing for expansion and upgrade functionality.
Controls can be managed via the push buttons of the front panel interface, or with remote control panels connected via Ethernet or RS-232 connectivity through a standard D-sub connector. Panels can be configured to control a single output bus or the entire matrix. The control panel supplied with this switcher is shipped installed in front of the main electronics chassis, but can be removed in the field and installed in a separately available remote-mounting kit. The router also includes a local control panel for audio breakaway.
The unit's power supply is accessible from the front of the unit and can be easily removed or installed as needed. A redundant power supply is also separately available. It is designed for placement in any standard 19" rack.
