The ZIG-POE-AHTX is a 100-meter (328 feet) HDBaseT transmitter. The AHTX has 3 inputs with auto-switching – HDMI, VGA/Component and Composite. With switchable POE it can be set up to power upstream and downstream HDBaseT transmitters and receivers. The ZIG-POE-AHTX can be used stand-alone as an HDBaseT transmitter, but really shines when paired with the ZIG-POE-RXAV receiver/scaler & audio amplifier. A perfect “no-control” control system using “on-connection” technology to fire up projectors, drop screens and control lighting in small rooms – BYOD and in seconds collaborate with your colleagues with full audio and video in stunning 4K UHD. A must for conference rooms and huddle spaces.
