RGB Spectrum has announced the SnchroMasterÆ 450, a synchronous switcher with and internal video scaler. Designed for staging large-scale, multimedia presentations, the SynchroMaster 450 is a full-blown multimedia system which allows the user to switch seamlessly between multimedia and computer signals, with clean cuts, dissolves, and wipes.The SynchroMaster offers user-programmable output timing to optimize the video signal for any given project. It presents a common, unbroken sync signal to the projector, whatever the signal source, and therefore there is no visual glitch when switching. Moreover, since all signals are converted to a common sync, there is only one projector set-up.The SynchroMaster 450 offers the capability of handling a full range of video and computer signals. More flexible than other synchronous switchers in the market, the SynchroMaster 450 will accept any computer signal up to 1280 x 1024 screen resolution, and video signals including NTSC, PAL, and CCIR 601 digital serial video. The system will accept up to four computer and/or video signals directly, or any number of inputs with an external switcher.When handline video inputs, the SynchrMaster 450 offers state-of-the-art decoding, adaptive comb filtering, and de-interlacing for superior image quality. The system eliminates flicker, cross color and dot crawl, and visible line structure in video.The SynchroMaster 450 is an external standalone system with control via a front panel or RS-232 port. It may also be run from an external computer using an advanced application program that mimics the front panel. Features include dissolves, fades to and from black, preview channel, and switcher-like panel.The SynchroMaster 450 is the most versatile synchronous switcher on the market today, with features and a range of inputs previously unavailable.RGB Spectrum is a leading designer and manufacturer of videographic and multimedia products for workstations and personal computers. In addition to the SynchroMaster display signal synchronizers, products include the VLI 200ô video scaler, the RGB/VideolinkÆ line of scan converters, the SuperViewô video windowing systems, and the ComputerWallô multi-screen display controller.
