IN1508 Scaling Presentation Switcher with PIP 60-569-01

The Extron IN1508 is an eight input, AV presentation switcher that accepts and scales a wide range of video signals to a common, high resolution output rate. It can accommodate two composite video, two S-video, one standard or high definition component video, one DVI-D, and two RGB computer-video sources. Eight input stereo audio switching is also provided with independent gain and attenuation control. The ability to accept multiple inputs of varying formats along with many other convenient and useful features make the IN1508 a true presentation switcher that is an ideal centerpiece for mid-sized AV systems.

The IN1508 features a high performance scaling engine with the ability to scale standard definition video, high definition video, and computer-video signals up or down in resolution. With the IN1508, only a single RGBHV connection to the display is required, resulting in cost savings due to reduced installation time, cabling, and system programming. The IN1508 outputs RGB or component video output with selectable output rates from VGA (640x480) to WUXGA (1920x1200) resolution, as well as HDTV at 720p, 1080i, and 1080p/60.

For more enhanced, professional presentations, the IN1508 includes seamless switching between video and RGB inputs with selectable cut or fade to black transitions. The IN1508 also features a PIP picture-in-picture mode that allows a video source and an RGB source to be shown on one display. Several PIP presets are available, including side-by-side windows, and the PIP window can be dynamically positioned anywhere in the image.

The IN1508 is equipped for integrator friendly access and configuration, as well as user friendly operation via the front panel, RS-232, and the included IR 903 infrared remote control. An on-screen display facilitates easy menu navigation as well as display of operational information pertaining to the selected input and system settings. The IN1508 is housed in a 1U, full rack width enclosure and can easily be integrated into many environments.
