BEFORE YOU BEGIN
For the best product performance and the lowest use of
pain-killers, nothing is better than a well-planned profes-
sional system installation. Before you start pulling wires,
sketch out a full layout of the complete system. This will
help plan the wire routing and minimize the “gotchas” later
on. Happy installing.
Installation Notes
Mounting The BVD-10 / BVR-10
The small size and low power draw of these units allow
them to be mounted in almost any dry indoor location. Pick
mounting locations close to the units that will be connected
to the BVD-10 or BVR-10. This keeps the unbalanced
audio and video signal cables as short as possible since they
are more susceptible to noise pickup than the balanced Cat-
5 cables. There is no heat build-up problem, so it is okay to
put the BVD-10/BVR-10 in a closed area. Just remember
you need to at least be able to reach the units.
Important Note: When routing the 24 volt AC
power wiring from the wall plug transformer; make
certain that you do not run the power wiring near or
parallel to the signal cables. You may pick up AC hum.

Wiring The System
Signal Wiring
The BVD-10 / BVR-10 system operates using standard
unshielded twisted-pair (UTP) Category 5 wiring. Good
wiring practices will minimize the chance of any noise
pickup.
• Do not run the signal cables parallel to AC power
wiring.
• If you need to cross over a power wire, try to do it at
right-angles.
• Keep the signal wiring as far as possible from any noise
sources such as lighting power supplies, fluorescent
lights, motors, etc.
Grounding
If you use a shielded Cat-5 cable, then you need to be
careful about ground loops. In some instances it is necessary
to only connect the shield at the receive end of the balanced
line and NOT on the other end. This provides a ground path
for noise picked up by the shield, but it prevents a continuous
signal ground path between the source and destination units.
Power Wiring

Important Note: Do not connect the
power supply to the ground terminal.
The BVD-10 and BVR-10 operate
from a 24 volt AC wall plug trans-
former. There is no polarity on the
power wiring from the transformer so it
can connect either way to the connector
block on the unit. The power draw is
very low on these units (each unit draws
approximately 50 milliamps) so you can

tap the supply from another 24 VAC transformer if it’s
handy.
RJ-45 connector
with wires
Handy Tip: For remote applications the BVD-10 and
BVR-10 will work very well from a 12 volt battery
supply. There is a small decrease in the maximum audio
signal level headroom, but the video performance is
unaffected by the reduced supply voltage.
Cat-5 Wiring
The RJ-45 connection on the BVD-10 and BVR-10
conform to the EIA-568B standard. This is the same Cat-5
cable wiring standard that a typical
computer network utilizes. You can
use any existing 10/100Base-T
network cabling and patch bays in an
installation as long as it does not run
through a router or hub. The Cat-5
wiring must run directly from the
BVD-10 to the BVR-10.
While the Active-Balanced video
components are designed to operate
with full-quality video on up to 1000
feet of CAT-5 wiring, it is possible
to get a very usable image up to
2000 feet away. There will be a slight softening to the
picture, but many people would not even notice this. If you
require a high-quality image on an extended (over 1000
feet) run, then you should use a second pair of BVD-10/
BVR-10 as a repeater. This will provide the additional
signal gain and cable compensation for the extra CAT-5
wiring.

Video Wiring
The BVD-10 and BVR-10 are capable of extending two
video channels. This can be two separate composite video
signals OR one S-video signal. The reason you are limited
to one S-video signal is that it is actually comprised of two
video signals; the Chroma and the Luminance. In applica-
tions where you need to
extend a component video
signal, you may use the RCA
video inputs on two pairs of
BVD/R. This gives you the 3
channels of video required
(plus a spare). Video connectors on BVD/R
Adapting composite to S-video
Important Note: You cannot simultaneously use the
Composite and S-video connectors on either unit.
The BVD-10 and BVR-10 automatically adapt a compos-
ite video input on
the BVD-10 to an
S-video output on
the BVR-10 (or
vice versa). To use this
feature, connect the com-
posite video signal to Input 1
on the BVD-10 and connect
to the S-video output on the
BVR-10.
Installation Note: The com-
posite to S-Video feature does not
function on Video Input #2.

Adjusting the Controls
Properly adjusting the level controls will give you the
highest headroom and the best signal to noise ratio. Please
note that the BVD-10 Audio Gain control is capable of up
to 20 dB of gain while the Audio Output level control on
the BVR-10 is attenuate only. This minimizes the chance of
system gain noise due to excessive gain at the receiving end
of the balanced line. The two video adjustments work in a
different manner. The Cable Compensation control on the
BVD-10 equalizes the video signal to counteract the effect
of wire capacitance. The Video Level adjustment on the
BVR-10 increases the gain of the video signal to make up
for line losses.

Audio Gain Adjustment – Simply use these controls to
adjust the audio volume of the remote video source. We find
that it is usually beneficial to apply some gain (about 6-
10dB) at the BVD-10 driver end and then use the Output
Level control on the BVR-10 to bring the volume back
down to your desired level. This helps improve the overall
signal-to-noise level of the audio system. The only time this
additional gain may be a problem is using professional
equipment with high (+4dBu) audio signal outputs.
Video Gain (Brightness) Adjustment – The video gain
adjustment on the BLD-10 allows matching the picture
brightness between the remote video signal and the local
sources. As you increase the video gain, the picture be-
comes brighter. Toggle between a local video source and
the remote source running through the BVD-10/BVR-10.
Turn up the Video Gain control until there is no apparent
change in picture brightness between the two sources.
Cable Compensation Adjustment – As the run length of
a Cat-5 cable is increased, the additional cable capacitance
causes a loss of picture quality. The Active-Balanced cir-
cuitry in the BVD-10 provides the means for correcting this
with the Cable Compensation control. Note that this control
is labeled in distance. Estimate approximately how long the
cable run is from the BVD-10 to the BVR-10 (no need to
be precise here) and adjust the Cable Compensation
control for that distance. It is useful to have a video test
signal or a television picture with strong vertical lines to
make the final adjustments. Set the Cable Compensation
control for minimum smearing along the vertical lines.

Troubleshooting
“No Picture or Sound.”
1.Make certain the BVD-10 and BVR-10 both show
power lights.
2.Verify that the Cat-5 cable is properly terminated on
both ends.
3.Verify the signal connection cables.
4.Make certain the Cat-5 cable run does NOT go through
an Ethernet Router or hub. It is alright to run the signal
through a passive patch bay.
“No Power Light.”
1.Make certain the two wires from the power supply are
connected to the 24 VAC connections on the terminal
block. Do not connect the external power supply to the
Ground terminal on the 3 pin connector block. This is
for shielding purposes only.
2.Double-check that the power supply is plugged in and
that the outlet has power.
“The video picture is dark.”
1.Turn up the Video Gain adjustment on the BVR-10.

ACTIVE-BALANCED SERIES
13
“The picture on my TV is fuzzy.”
1.Adjust the Cable Compensation control on the BVD-10.
This compensates for the increased capacitance on
longer Cat-5 cable runs and sharpens the video image.
“There is hum in the audio signal.”
1.Verify that the Cat-5 cable is properly terminated on
both end.
2.Make certain that the system is wired with twisted-pair
cabling.
3.Try turning up the output level on the BVD-10 driver.
4.Make certain there is not a cut in the wiring allowing a
conductor to short to ground (i.e. shield, conduit, cold
water pipe, plenum).
“The sound is distorted.”
1.The output level on the BVD-10 may be set too high.
2.The signal level feeding into the unbalanced RCA audio
inputs of the BVD-10 is too high (not likely with con-
sumer grade equipment).

and now a word from the legal department...
CONDITIONAL FIVE YEAR WARRANTY
Custom electronics installations are an invisible element of
many modern homes. You don’t appreciate what they do for
you unless something goes wrong. AudioControl recognizes
this fact and engineers the most bullet-proof components we
know how. To stand behind that quality, we provide a full
FIVE YEAR parts and labor factory warranty. Our war-
ranty returns are rigorously tracked and less than 0.5% of
all the units we build ever need to be repaired.
“Conditional” doesn’t mean anything ominous. The
Federal Trade Commission tells all manufacturers to use the
term to indicate that certain conditions have to be met
before they’ll honor the warranty. If you meet all of these
conditions, we will warrant all materials and workmanship
on the BVD-10 / BVR-10 for FIVE YEARS from the date
you bought it, and we will fix or replace it, at our option,
during that time.
Here are the conditional conditions:
1.A completed warranty card must be returned to us
within 15 days after signing off on the BVD-10 / BVR-
10 installation.
2.A sales receipt is required for proof of purchase show-
ing when and from whom the unit was bought. We’re
not the only ones who require this, so it’s a good habit
to get into with any major purchase.
3.The BVD-10 / BVR-10 must have originally been
purchased from or installed by an authorized AudioCon-
trol professional. This warranty is transferable. You do
not have to be the original owner, but you do need a
copy of the original sales slip.

ACTIVE-BALANCED SERIES
15
4.You cannot let anybody who isn’t: (A) the AudioCon-
trol factory or (B) somebody authorized in writing by
AudioControl to service your BVD-10 / BVR-10. If
anyone other than (A) or (B) messes with your BVD-10
/ BVR-10, that voids your warranty.
5.The warranty is also void if the serial number is altered
or removed, or if the BVD-10 / BVR-10 has been used
improperly. Now that sounds like a big loophole, but
here is all we mean by it:
Unwarranted abuse is: (A) physical damage (don’t use the
BVD-10 / BVR-10 to level out a bookcase); (B) improper
connections (120 volts into the power jack can fry the poor
thing); (C) sadistic things. This is the best product we know
how to build, but if you mount it to the filter pump of a hot
tub, something will probably go wrong.
Assuming you conform to 1 through 5, and it really isn’t
all that hard to do, we get the option of fixing your old unit
or replacing it with a new one.
Legalese Section
This is the only warranty given by AudioControl. This
warranty gives you specific legal rights that vary from state
to state. Promises of how well your BVD-10 / BVR-10 will
perform are not implied by this warranty. Other than what
we have covered in this warranty, we have no obligation,
express or implied. Also, we will not be obligated for direct
or indirect consequential damage to your system caused by
hooking up the AudioControl BVD-10 or BVR-10.
Failure to send in a properly completed warranty card
negates any service claims.
