The SCU91T is a 9 inputs multi-format A/V presentation auto 4K Scaler Switcher that scales video signals to HDMI and HDBaseT outputs simultaneously. The HDBaseT output supports 48V PoH and can connect to a compatible HDBaseT receiver up to a maximum of 100 meters (328ft).

With 1 IR ALL IN and 1 IR ALL OUT, the IR control signals can be transmitted bi-directionally between the SCU91T and compatible HDBaseT receiver or HDBaseT Transmitter.

The SCU91T can be controlled either by front panel buttons, IR Remote, RS232 or GUI. With a microphone input that supports phantom power and a balanced stereo audio output for audio reinforcement, the SCU91T can handle a myriad of A/V applications.
