Addressing the need for simple, reliable switching and scaling of digital and analog inputs to office and classroom AV systems, Atlona has introduced the AT-HD-SC-500, a three-input HD scaler which can select input signals through auto-sensing, front panel control, or remotely via RS-232 or IP control. Designed to take video signals from AV sources, switchers, or computers, the new scaler can scale them to an HDMI output in a wide-range of HDTV and PC resolutions, up to 1080p/60Hz and WUXGA (1920x1200). Audio features include a stereo input for the VGA source, de-embedded audio from the HDMI inputs, and a balanced stereo output. The unit accommodates two HDMI sources and one VGA source and provides one HDMI output. In addition to RS-232 and TCP/IP control, the device features a built-in web server with a GUI, allowing rapid, remote configuration. LEDs indicate power state and active input source, and front-panel controls include manual source selection and volume adjustment, including mute. The HD-SC-500 can be rackmounted or located adjacent to source or display devices. Power is provided by an included 5V power supply.
