特性

　　Inputs: Female 15-pin HD and five female BNCs with buffered loop-throughs

　　Outputs: RGBHV on five BNCs, S-video on 4-pin mini DIN, and composite video on female BNC connector

　　Automatically recognizes and converts computer resolutions from 560x384 to 1600x1200 and frequencies to 100 kHz horizontal and 120 Hz vertical

　　Buffered loop-through — Provides a local monitor output, enabling the computer input signal to be monitored without the need for a separate distribution amplifier.

　　Three simultaneous outputs — NTSC or PAL standard video is output as composite video, S-video, and component or RGB video.

　　Auto-Image™ setup — Saves time by providing calibration of image size, position, clock, and phase adjustments at the touch of a button.

　　Vertical filtering — Four selectable vertical filters reduce jitter, improve image quality, and help maintain picture detail.

　　Horizontal filtering — Eight selectable horizontal filters prevent aliasing or pixel elimination so that less detail is dropped when the image is scanned from left to right.

　　Sizing and centering controls — User-friendly positioning is accessible through the front panel for quick and efficient image setup.

　　Image zoom control and presets — Eight zoom presets are available for recalling size, position, and filtering, enabling the user to quickly zoom in on a certain area of an image.

　　Input memory presets — Allow the scan converter to automatically recall up to 16 user presets, 60 factory presets, and eight zoom presets. Each memory location stores filter, size, and centering, or zoom settings for each source which can be recalled instantaneously when switching between different computer-video inputs and resolutions.

　　Image freeze control — The output video can be frozen using the freeze button on the front panel. This allows the scan converter to capture a frame of video to display for an extended period of time, even after the source has been removed.

　　Internal test pattern generator — The VSC 900 offers four test patterns – color bars, 32 x 32 crosshatch, 4 x 4 crosshatch, and gray scale – for quick and easy monitor set-up.

　　Video genlock — All NTSC and PAL video outputs can be synchronized to an external reference signal for integration into broadcast and production applications.

　　Chroma attenuation — Ideal for broadcast environments where colors in logos and images must be set at 75% saturation for transmission. The VSC 900 has the ability to attenuate an input signal's chroma level down to the correct output level, eliminating the need to recreate the image and/or content.

　　RS-232 and RS-422 serial control port — Using serial commands, the VSC 900 can be controlled and configured via the Extron Windows®-based control program, or integrated into third-party control systems. Extron products use the SIS™ - Simple Instruction Set command protocol, a set of basic ASCII code commands that allow for quick and easy programming.

　　Optional IR remote control, part # 70-206-01 — The optional VSC Remote handheld IR remote control performs most front panel functions such as image freeze, zoom in and out, size and shift, vertical filter adjustment, and preset selection.

　　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.

　　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.
