The AEC-1 and AEC-2 are small 10x1 and 10x2 video/audio
routing switchers. Both models are designed with audio follow video, but the
AEC-1 also has audio and video breakaway available.
BROADCAST QUALITY ROUTING SWITCHERS
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
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
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.

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
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
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
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.
