Contemporary Research Corporation 3 AV6x4 A/V Router
Overview
Contemporary Research presents the AV6x4, a flexible, controllable matrix switcher for routing six
stereo A/V inputs to four stereo A/V outputs. Using the simplified front-panel controls, it's easy to
switch VCRs, DVDs CDs, cameras and other sources to TVs, projectors, and plasma displays. Route
and input to any combination of outputs, send both audio and video, or switch audio and video
separately. Advanced capabilities are available from front-panel programming as well, including
adjusting input levels, setting RS-232 baud rate and device number, and selectively enabling or
disabling front-panel features.
The AV6x4 is a popular choice for conference rooms, home theaters, and classrooms because it is
easily controllable by computer software and custom control systems. Up to three switchers, as well
as CR stereo TV and FM tuners, can be controlled by a single RS-232 control port. Simple and logical,
the AV6x4 ASCII protocol is easy to integrate for system control, setup, and feedback.
• Switches six A/V inputs to four outputs
— BNC video inputs and outputs (composite NTSC, PAL, SECAM)
— Vertical interval routing for clean glitch-free switching
— Internal DIP switch provides 75 ohm input termination or Hi-Z video T-connection
— Stereo gold RCA inputs and outputs
— Audio-follow-video or breakaway audio and video switching
— Adjustable sound levels help balance audio from input sources
— Master Mute for all video and audio outputs
• Operates from RS-232 control port or front-panel control
— Simple ASCII commands and feedback for computer or control system integration
— Opto-isolated RS-232 port reduces interference and ground loops
— Control up to three switchers or other CR RS-232 products from a single RS-232 control
port
— Programmable front-panel control enable/disable
• Simplified front-panel switching control
— Select switching Mode (video, audio or both)
— Select output A, B, C, or D, LEDs display current input for both audio and video
— Press desired Input to execute switch, LEDs change to show new routing status
• Restores all operation status after loss of power from data stored in non-volatile memory
• Mounts on shelf or in 19” equipment rack
