About the Switcher

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

•Two NTSC/PAL/SECAM/NTSC 4.43 composite video inputs on female BNC connectors

•Two S-video (Y/C) inputs on 4-pin mini DIN connectors

•One component (YUV) video input (progressive [Y, B-Y, R-Y] or interlaced [Y, B-Y, R-Y]) on female BNC connectors

•Two VGA – UXGA (RGBHV or RGBS) inputs on 15-pin HD connectors

•One digital visual interface (DVI), direct digital input on a DVI-I female connector (see “DVI video” in this chapter for an introduction to the DVI video format)

With the proper adapters, the IN1508 can also be used with High Definition

Multimedia Interface (HDMI™) signals.

•Eight unbalanced stereo or mono audio inputs (five inputs on RCA connectors and three inputs on 3.5 mm mini stereo jacks)

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.
