NOTE: As of Aug. 31, 2007 - We are winding down production on this product line as we can no longer obtain the switches for this product without ordering very expensive 'custom' production. At this time, we do not expect to be able to fill any orders beyond those that we already have received. Thanks for your support. We should be able to handle additional orders for those parts/models that do NOT require switches for a short time.
Note: Sept. 2009 - We have only a couple of base model units available and a small selection of optional parts, etc. Contact the factory for specific availability if you are interested in getting any of these parts/options.


By "small" we mean our 10 input, 1 output (10x1) model "AEC-1" video/audio routing switchers, and our 10 input, 2 output (10x2) model "AEC-2" video/audio routing switchers. Somewhat larger routing systems (up to 100x1 or 10x6) are possible by connecting several of these routing switchers together (call for details).

Key features of these routing switchers include broadcast quality audio and 30MHz video signal switching, up to three 10x1 audio boards in a 1RU chassis, proven high reliability (over 100 years actual MTBF), and our reasonable prices and availability.

TV stations, production studios, network facilities, automation systems, and important educational and corporate clients depend on us 24 hours a day for smooth and reliable signal switching.

Options for these routing switchers include an RS232/RS422 serial interface board, a dual tally relay board, a screw terminal audio wiring adapter board, and a variety of serial and parallel remote control solutions.

Below you will find specifications, model numbers, prices, and other information you need to reach a decision.

So, the next time you need a small routing switcher, buy a good one (from Adrienne Electronics). Please call Tracey at 1-800- 782-2321, or at the number above, if you have any questions or wish to place an order. We look forward to hearing from you.

Sincerely,

Tracey Ruesch, President

INTRODUCTION TO SMALL ROUTING SWITCHERS

We introduced the AEC-1 series of routing switchers in May 1987 to address the need for high quality, reliable, yet reasonably priced 10x1 routing switchers. 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.

AEC-2 10x2 ROUTING SWITCHER INFORMATION

The AEC-2 series of 10 input, 2 output (10x2) routing switchers are derived from, and very similar to, their AEC-1 predecessors. They pack twice as many crosspoints into the same 1RU enclosure, yet cost only about 50% more than their 10x1 counterparts. Each output can independently select any one of the ten common inputs. For example, one output can be looking at input 3, while the other output is looking at input 10. All AEC-2 characteristics are identical to those of the AEC-1, except as noted below.

AEC-2 CONTROL SYSTEM NOTES

The AEC-2 uses the same remote connector pinout, control panels, serial remote protocols, etc., as the AEC-1, except that the AEC- 2's two control levels are used for what we call the "RED" and "GREEN" outputs, which correspond to the colors of the tally LED's on the front panel. The AEC-2 thus has no audio breakaway capability (the audio always follows the video). Furthermore, either the "RED SELECT" or "GREEN SELECT" button must be held down while making crosspoint selections (determines which output will be changed). If both buttons are held down, both outputs change. If neither button is held down, no outputs change, which prevents accidental changes to one or both of the outputs.

AEC-2 VIDEO NOTES

The AEC-2 video performance is identical to that of the AEC-1, except that the gain for each video output is internally fixed at unity, +0.1dB. Also, each of the two video output signals has its own two isolated output BNC's, so there are a total of 4 video output BNC's (2 per output signal).

AEC-2 AUDIO NOTES

Because of space limitations, the AEC-2 can have at most two(2) audio crosspoint boards installed. The 10x2 audio specifications surpass those of the 10x1 router, with >66dB common mode rejection, <-96dB worst case crosstalk, and >120db signal/noise. The audio gain is internally fixed at unity, +0.05dB.

GVG TEN-XL COMPATIBILITY NOTES

The AEC-1 is both hardware and software compatible with the GVG TEN-XL 10x1 routing switcher. It is a well known fact that our owner, Bruce Waggoner, designed the hardware and wrote the software for both products. The AEC-1 is significantly different on the inside, yet maintains complete external compatibility. The audio connector pinouts are identical. The remote control connector pinouts are identical. The ASCII and SMPTE serial interface protocols are identical. Remote control panels from one product will control the other product.

However, as noted, there are some differences. The TEN-XL has differential video inputs, optional dual power supplies, and removable boards. The AEC-1 has better video performance, higher reliability (fewer connectors to fail), up to three audio boards in one chassis, toll free technical support, and costs about $500 less than the TEN-XL. Thus, if you don't need removable boards and dual power supplies, our AEC-1 is a better choice.

GENERIC ROUTING SWITCHER NOTES

One of the key specifications which is often missing or fudged on other routing switchers is "crosstalk". Any device which has a lot of audio and video signals going into it will have an output which (by nature) contains a small amount of every input signal. The total amount of unwanted signals getting into the desired output signal is termed "crosstalk". Crosstalk tends to get worse at high frequencies, and requires a lot of work to be kept to a minimum.

High quality routing switchers (such as ours) have very low crosstalk, even at the high frequencies. Some routing switcher manufacturers hide their product deficiencies by only measuring crosstalk at low frequencies (where crosstalk is much lower), or by measuring crosstalk with only one other input signal connected to the routing switcher (bogus). Compare our audio and video crosstalk specifications with theirs. If they are hiding something in this category, look out.

Other key specifications include maximum audio level, video bandwidth, differential phase and gain, and the retention of high impedance audio/video inputs even if the power fails.

We invite you to compare our proven track record, reliability, performance, control options, availability, and prices against those of any other router manufacturer. We are confident you will call us when ready to order.
