System 7SC

60-340-01

The Extron System 7SC is a seven input, dual output, multi-format active switcher with a built-in video scaler. The System 7SC features projector and room control along with RGB and video integration capabilities ideal for permanent installations and staging applications using plasma displays as well as CRT, LCD, D-ILA™/LCoS, and DLP projectors.

To optimize image quality as well as maintain maximum image brightness and detail, video inputs are scaled to match the native resolution of the digital display being used. To scale any video input, the System 7SC uses Extron's proprietary up-conversion technologies with Dynamic Motion Interpolation (DMI™) technology and advanced film mode processing. RGB inputs are passed through.

The System 7SC provides Extron's patented Accu-RATE Frame Lock (AFL™) technology, which solves frame rate conversion issues experienced by video scalers. The System 7SC incorporates advanced film mode processing with 3:2 pulldown detection for NTSC and 2:2 film detection for PAL to help maximize image detail and sharpness for sources that originated from film.

The System 7SC includes two methods of projector control: RS-232 or IR. There are also two methods of configuring the switcher for projector control. The first method consists of downloading pre-configured control drivers from the Extron Web site via the supplied control software. The second method is IR learning which is available for more customized configuration. The installer can customize the System 7SC by using IR learning or entering custom, unidirectional, RS-232 commands.

System switcher control is provided via front panel operation, the included IR 701 remote control, RS-232 control, or the optional SCP 200 or SCP 250 hardwired control pads. The front panel buttons control video and audio input selection, picture adjustments, display functions, and internal relays for room controls, such as lowering or raising a screen. The IR 701, SCP 200, and SCP 250 duplicate most or all of the front panel functions. All functions are available through RS-232.

Features

Inputs- Seven inputs. Six of the inputs are fully configurable for composite video, S-video, component video, or RGB. Located on the front panel, the seventh configurable input accepts composite video, S-video, or RGB on a 15-pin HD. The System 7SC also accepts and scales 480p component video signals to any of the available output rates.
Scaled outputs- Every composite video, S-video, and component video signal is scaled and output simultaneously on a 15-pin HD connector and five BNCs.
Universal projector control- The System 7SC provides universal projector control via downloadable RS-232 or IR drivers, IR learning capabilities, or user-defined RS-232 commands.
Room control- Room lighting, screen settings, and other device functions may be controlled via internal relays.
Triple-Action Switching™ (RGB delay)- Blanks the screen during switching to eliminate visible switching transitions.
Balanced/unbalanced audio- Audio gain/attenuation adjustments for each input provided. Audio breakaway available through RS-232 only.
Dual audio output- Simultaneous output available, one with fixed level and one with variable level. Input level adjustments made using the front panel knob or RS-232.
Quad standard video decoding compatibility - The System 7SC uses a digital, four-line adaptive comb filter to decode NTSC 3.58, NTSC 4.43, PAL, and SECAM.
Accu-RATE Frame Lock (AFL™)- A patented technology exclusive to Extron that solves frame rate conversion issues experienced by video scalers. When video input and output refresh rates differ, there are certain points in time when the two rates cross over each other. The result is a glitch or image freeze on the display. AFL solves this problem by locking the output frame rate to the input frame rate.
Dynamic Motion Interpolation (DMI™)- DMI technology is an advanced motion detection and compensation method used to deliver the best aspects of still and motion algorithms. This process results in a superior level of image enhancement capability with no loss of image fidelity.
3:2 (NTSC) and 2:2 (PAL) pulldown detection - Advanced film mode processing techniques which help maximize image detail and sharpness for NTSC or PAL sources that originated from film (Patent Pending).
Pass-through outputs- All RGB inputs are passed-through and output simultaneously on a 15-pin HD connector and five BNCs.
Picture controls- Horizontal and vertical shift, color, tint, brightness, contrast, detail (image sharpness), sizing, and top and bottom vertical blanking adjustments provided for each video input.
Rack-mountable- Housed in a 2U, full rack width metal enclosure.
