The Extron IN1508 is an eight-input video and stereo audio switcher that
incorporates a video scaler (figure 1-1). The switcher accepts:

The IN1508 scales the video inputs to a variety of standard VGA and HDTV
resolutions and any of up to 3 available refresh rates. The switcher outputs
RGBHV, RGBS, RGsB, or progressive component (Y, B-Y, R-Y) video on a 15-pin
HD (VGA) connector. It outputs stereo or mono audio on left and right RCA
connectors and a 3.5 mm 5-pole captive screw connector. The IN1508 allows all of
the input formats listed above to be displayed on a device with a fixed resolution
and aspect ratio, such as a liquid crystal display (LCD) projector, digital light
processor (DLP) projector, or plasma display.
The IN1508 seamlessly switches between the VGA and low-resolution video
inputs. Seamless switching allows switching between sources without a loss of
sync.
The switcher's scaler upscales or downscales, converting the horizontal and
vertical sync timing and the number of lines of the video input to match the native
resolution of the display. This produces an undistorted, brighter picture.
The switcher is housed in a 1U high, 17.5" wide metal enclosure. With the included
mounting ears, the switcher is rack-mountable. With optional mounting hardware,
the switcher can be mounted under or through furniture or other mounting
surface. The switcher has an internal 100 VAC to 240 VAC, 50/60 Hz, 40 watts,
autoswitchable power supply that provides worldwide power compatibility.
