Multiple Input A/V Switcher-Scaler for Conference Rooms with Built-In Audio Amplifier Integrating multiple audio/video sources in a professional setting has never been easier. Gefen's new A/V Conference Room Processor with built-in audio amplifier connects set top boxes, Blu-ray players, gaming consoles, computers and more. Video is scaled and output in HDMI format with cinema-quality scaling up to 2K or 1080p Full HD resolution, supporting large-scale HDTV displays. The audio is mixed down from 5.1 Dolby? surround to two-channel audio with support for a powered subwoofer. A built-in 2-channel audio amplifier delivers 25 watts per channel from digital and analog sources, ideal for creating high-fidelity sound in the conference room environment. Two speakers may be connected directly to the amplifier binding posts for ""plug and play"" installation in any conference room, educational facility or presentation venue. How It Works: Connect each video input source and corresponding audio source to connectors on the front or rear panel. Power up the A/V Conference Room Processor. The buttons on the front panel are used to select the active A/V source. Use the LCD menu system to select the scaler output resolution and desired A/V processing functions. The A/V Conference Room Processor will convert the selected A/V inputs to HDMI video output with two-channel analog line-level and speaker-level with powered subwoofer support.
