Nortek Security & Control (NSC) today announced that it is now shipping the Gefen 4K 600 MHz 4×1 multi-view seamless switcher (EXT-UHD600A-MVSL-41).

Audio from any of the four HDMI sources can be selected via IR, RS232 or IP, for playback through the HDMI output and the L/R analog audio output. Plus, the analog audio is de-embedded from the HDMI output and can also be routed to an outboard sound-reinforcement system.
The switcher is controllable via front panel buttons, its handheld IR remote control, RS232 and IP (web server interface, Telnet and UDP).
