From Extron:

The Extron System 10 Plus switcher with universal projector control accepts RGBHV, RGBS, RGsB, S-video, composite video, and stereo audio signals. The System 10 Plus provides 250 MHz (-3dB) video bandwidth, and is ideal for large-scale AV systems integration and staging applications.

For audio switching, audio attenuation and audio breakaway are available. VLB - Video Loop Back is also supported, allowing the switcher to work with any external decoder or scaler. With the VLB method, only one signal processing device needs to be used in order to decode or scale all the switcher's input signals. System switcher control is provided via front panel operation, RS-232 control, contact closure control, or the optional IR 301 remote control.

Features

• 250 MHz (-3dB) RGB video bandwidth
• Inputs: Configurable inputs for RGBHV, S-video, and composite video; stereo balanced/unbalanced audio inputs
• Outputs: One RGBHV, one S-video, and one composite video output; one balanced/unbalanced audio output
• Compatible with RGBHV, RGBS, RGsB, S-video, and composite video signals
• Triple-Action Switching™ for RGB delay — Blanks the screen when the switcher switches to a new source, eliminating visible switching transitions.
• Universal projector control via RS-232 — The System 10 Plus provides control for various projectors by using projector-specific communications adapters for connection to the model being used. Call Extron or check the Extron Web site for a list of current compatible projectors and part numbers.
• Audio breakaway - available through RS-232 only
• Video Loop Back — Route video sources through an optional Extron QSD 204 quad standard decoder or Extron DVS 304 scaler, so only one signal processing device needs to be used for all switcher inputs. This feature enables one set of RGB cables to feed the switcher's output signals to any projector.
• Balanced/unbalanced audio — Audio may be routed as balanced or unbalanced audio. Attenuation adjustments provided for each input.
• RS-232 and contact closure remote control
• Backlit front panel buttons — Buttons provided for input switching, display mute, display power, RGB mute, and audio mute. Display mute mutes the image at the projector, RGB mute mutes the image at the switcher and works for RGB signals only.
• Front panel button labels — Backlit pushbuttons can be custom-labeled with text or graphics printed using Extron's Windows®-based software.
• Remote control capabilities with optional IR 301 Handheld IR Remote Control
• Input Expandability — Switchers can be looped together for additional input capability.
• 3U, full rack width metal enclosure — Rack-mounting brackets included.
• Highly reliable, energy-efficient internal universal power supply — The 100-240 VAC, 50/60 Hz, international power supply provides worldwide power compatibility with high demonstrated reliability.
