The AEC-2 followed several years later. Both routers have proven to be very reliable, with an actual (not estimated) Mean Time Before Failure (MTBF) of greater than 100 years. Most companies don't even know what their failure rates are. We also offer GVG TEN-XL control compatibility, reasonable prices, a two year warranty, plus toll free technical support should it ever be needed. We will begin below with a description of our 10x1 "AEC-1" routing switchers. AEC-1 CONTROL SYSTEM NOTES The front panel of the AEC-1 contains ten pushbutton switches numbered 1-10. Each switch selects its corresponding video and audio input signal(s) to appear at the output. If needed, the audio and video channels can be controlled independently of each other by use of the red and green "breakaway" buttons on the front panel, which must be held down whenever breakaway crosspoint selections are made. For example, video input 2 and audio input 4 can be selected simultaneously. Each switch assembly includes red (for video) and green (for audio) tally LED's, so that you always know how the routing switcher is configured, even when the router is controlled remotely. Also, the switch fronts can be easily labeled with standard (included) or custom mnemonics such as VTR1, CAM2, etc.. Each routing switcher includes a 24 hour (minimum) crosspoint memory which automatically restores the crosspoint status after power outages. AEC-1 VIDEO SYSTEM NOTES The broadcast quality 10x1 video switching system passes full amplitude 30MHz video signals for superior picture quality. All video inputs are high impedance looping, and are DC clamped for smoother switching. The video output gain is unity, adjustable +1dB via the front panel. The two isolated and source terminated video output signals are fully DC restored (black is at ground). Switching is always performed in the middle of line 10 of the video signal currently selected, with 50ms backup in case no video is present. All video paths are carefully matched for delay and frequency response characteristics. The video inputs remain high impedance even if the router's power supply fails, thus ensuring that other signal paths will never be interrupted. AEC-1 AUDIO SYSTEM NOTES The 10x1 audio switching system has high impedance differential balanced inputs, and low impedance differential balanced outputs. The output gain is nominally unity, but may be adjusted +7dB/-3dB from the front panel. Signal amplitudes up to +24dBu can be handled without clipping. Audio inputs remain high impedance should the router's power supply ever fail, thus ensuring that other signal paths will never be degraded. Audio connections to the routing switcher are made through a 37- pin "D" connector. We supply the mating connector parts at no charge. Alternatively, you may purchase the "SCRW" screw terminal adapter boards to make the wiring a bit easier, although high frequency audio crosstalk will increase somewhat. A significant advantage of the AEC-1 over other models is its ability to hold up to three 10x1 audio boards in its 1RU enclosure. The third audio channel is commonly used for time code (LTC) or second language broadcasting. Audio boards can be easily added in the field should your needs change in the future. If more than 3 audio channels are needed, an "audio slave" router can be added, which then expands system capacity up to a total of 6 audio boards. Call if you need further information. SERIAL REMOTE CONTROL OPTIONS The routing switcher can be controlled by either RS232 or RS422 serial remote control messages if the internal "SIO" serial interface option board is installed. We fully support the standard ASCII and SMPTE protocols of the GVG TEN-XL, and have developed quite a few other operating modes for security and other special applications. The "SIO" board can be easily added in the field. When ordering, please specify the protocol, address, baud rate, data bits, and parity you desire (call if you have any questions). You can always change the setups in the field, but it's even easier if we do it for you ahead of time. The AEC-1/SCP serial remote control panel looks just like a standard AEC-1 routing switcher, but contains only pushbuttons, a serial board, and a power supply. It controls our routers remotely via RS232 or RS422 serial cables, including the use of modems and leased or switched telephone links if needed. The routing switcher being controlled by the serial control panel must have an "SIO" board installed (is standard inside the SCP). Please note that all serial connections to the router, while identical to those for the GVG TEN-XL, do not use computer industry standard RS232 or RS422 pinouts. Thus you will either need to order the appropriate cable from us or make your own. PARALLEL REMOTE CONTROL OPTIONS All routers come with a GVG TEN-XL compatible parallel remote control port on the back. This 25-pin "D" connector contains 5V CMOS control inputs and audio/video tally outputs, power for remote panels, and access to the serial interface board (if installed). Simple switch closures to ground can control up to 5 of the router's inputs. Encoding is required if all 10 inputs are to be controlled. The AEC-1/WPX board does this for you. The standard AEC-1/RCP remote control panel looks just like the front of the routing switcher, but without the fuse assembly and gain pots. The 18-conductor AEC-1/RCC remote control cable, which may be up to 300m (1000') long, is used to connect the remote control panel to the routing switcher. Multiple control panels, including the local panel, may be connected to a given routing switcher at the same time, provided that keys from two or more panels won't be pressed at the same time (gives indeterminate results until somebody lets go). COMPONENT VIDEO OPERATIONS It is possible to link several routing switchers together for wideband (30MHz full power bandwidth) component video applications. Typically the "Y", "G", or "S" channel is used as a sync source master, and the other routers in the system slave to it (switch at exactly the same time). The "YCC", "RGB", and "RGBS" router versions do not include audio, although audio channels may be easily added via the AEC-1/AUD option. INPUT EXPANSION OPTIONS By chaining 2 or more routers together, you can easily construct 19x1, 28x1, even up to 100x1 routing systems. To maintain signal quality, the audio/video signals never have to go through more than two router levels. The control systems of these routers are connected together via special remote cables (see ordering guide) so that you only need to press one button which corresponds to the desired signal source. All the other routers in the system will automatically change (as needed) simultaneously. OUTPUT EXPANSION OPTIONS Stacking routers and looping their inputs together can be done to create 10x2 or larger (up to 10x6) routing systems. Each system output then has its own power supply and local control panel. We recommend that no more than about 6 routers be connected in this fashion, because after that point it usually becomes easier to install, and more economical to purchase, a small matrix router. Even if you don't need this capability initially, it's nice to know that it can be done if your needs change. For some applications, the 10x2 AEC-2 router might be a prudent choice. Place a Bid!
