The Extron IN1508 is an eight input, A/V presentation switcher that accepts and scales a wide range of video signals to a common, high resolution output rate.

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 at 35 selectable output scan rates from VGA (640x480) to UXGA (1600x1200) resolution, as well as HDTV at 720p, 1080i, and 1080p.

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.

Features

• Integrates video, HDTV, DVI-D, and computer-video sources into presentation systems with audio switching — The IN1508 provides centralized switching for a wide range of A/V sources.

• Inputs: Two composite video on BNC, two S-video on 4-pin mini DIN, component video on BNCs, DVI-D, and two RGBHV on 15-pin HD; stereo audio for each input on RCAs or 3.5 mm mini jack

• Outputs: Scaled RGB or component video on 15-pin HD; stereo audio output on RCAs, stereo balanced/unbalanced audio output on captive screw connector

• RGB, HDTV, and video scaling — RGB computer-video, high definition video, and standard definition video sources can all be scaled to the desired output resolution.

• RGB upscaling and downscaling — The IN1508 features an advanced scaling engine with high quality upscaling and downscaling of high resolution computer-video signals.

• PIP - picture-in-picture mode — Allows a video source to be displayed within an RGB image, or vice versa. Six preprogrammed PIP window options are available, including side-by-side windows, with dynamic, fully adjustable window positioning. Audio follow can be set for either the main or PIP window.

• Seamless switching — Switching is seamless between RGB and video inputs with selectable cut or fade to black transitions. Presentations can be enhanced by eliminating distracting visual jumps, glitches, and distortion commonly seen when switching between computer and video sources.

• On-screen display — The IN1508 features an on-screen display which facilitates easy menu navigation for setup and operation, as well as display of information pertaining to the selected input and system settings.

• 35 output rates from 640x480 to 1600x1200, including HDTV 1080p — A total of 35 output scan rates are available including computer-video rates up to UXGA, 480p, 576p, and HDTV rates at 720p, 1080i, and 1080p.

• RGB or component video output

• Audio switching with input gain and attenuation — The IN1508 features stereo audio switching for each input source. Gain or attenuation can be adjusted for each input. Audio is output as balanced or unbalanced with output volume control.

• Picture controls for brightness, contrast, color, tint, detail, and horizontal and vertical positioning, sizing, and zoom

• Aspect ratio conversion — Any video input can be adjusted horizontally and vertically to meet a specific aspect ratio requirement. Alternatively, the input aspect ratio may be specified as 4:3 or 16:9 and fixed.

• Front panel security lockout — This feature locks out all front panel functions except for input selection; all functions however, are available through RS-232 control.

• 3:2 NTSC and 2:2 PAL pulldown detection — Advanced film mode processing techniques help maximize image detail and sharpness for NTSC or PAL sources that originated from film.

• Quad standard video decoding — The IN1508 uses a digital, four-line adaptive comb filter to decode NTSC 3.58, NTSC 4.43, PAL, and SECAM for integration into systems worldwide.

• IR remote control — The included Extron IR 903 handheld remote control allows for input source switching, picture-in-picture, and direct access to picture adjustments.

• RS-232 serial control port — Using serial commands, the IN1508 can be controlled and configured via the Extron Windows®-based control program, or integrated into third-party control systems.

• Rack-mountable 1U, full rack width metal enclosure

• Internal international power supply — The 100-240VAC, 50/60 Hz, autoswitchable internal power supply provides worldwide power compatibility.
