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. 
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 A/V 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 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 an Extron MLC - MediaLink™ 
  Controller, 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
