The First Step In Your Installation Procedure
FILL OUT AND SEND IN THE WARRANTY CARD!
Also, save the invoice or sales slip as proof of purchase.
These actions will protect this investment and help prove
that such a handy piece of audio equipment was really
in the system. Insurance companies can have such little
imagination when you are trying to make a claim.
Before You Begin
For the best product performance and the lowest use of
painkillers, nothing is better than a well-planned profes-
sional system installation. Before you start pulling wires
and punching holes in the walls, sketch out a full layout of
the complete system. This will help plan the wire routing
and minimize the “gotchas” later on.

Installation Information
Mounting the BVR-25
The small size and low power draw of these units allow
them to be mounted in almost any dry, indoor location,
specifically a single gang J-box (not provided). Pick mount-
ing locations close to the audio or video components that
will be connected to the BVR-25. You will want to keep the
unbalanced audio and video signal cables as short as pos-
sible since they are much more susceptible to noise pickup
than the balanced Cat-5 cables. Just remember you need to
at least be able to reach the units with a small screwdriver
to make any final adjustments
Video Wiring
The BVR-25 has 4 high-bandwidth outputs that are ca-
pable of extending component video signals (3 connectors,
Y, PB, PR) plus a composite video signal on the remaining
RCA connector. As an option, you can use the fourth RCA
connector on your BVR-25 to transmit a digital audio sig-
nal. The following system drawings reflect just a few of the
potential systems:
owner, but you do need a copy of the original sales slip.
4. You cannot let anybody who isn’t: (A) the Audio-
Control factory or (B) somebody authorized in writing by
AudioControl to service your BVR-25. If anyone other than
(A) or (B) messes with your BVR-25, that voids your war-
ranty.
5. The warranty is also void if the serial number is altered
or removed, or if the BVR-25 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 BVR-25 to level out a bookcase); (B) improper connec-
tions (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 BVR-25 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 BVR-25.
Failure to send in a properly completed warranty card
negates any service claims.

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 bulletproof components we
know how. We stand behind that quality, with a full FIVE
YEAR parts and labor factory warranty when our components
are installed by an authorized AudioControl dealer in the Unit-
ed Sates. Otherwise your warranty is one year. You will be
happy to know that our warranty returns are rigorously tracked
and very few of 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 BVR-25 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 BVR-25 installation.
2. A sales receipt is required for proof of purchase showing
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 BVR-25 must have originally been purchased from
or installed by an authorized AudioControl professional. This
warranty is transferable. You do not have to be the original

2.Check the Cat-5 wire configurations. Use an RJ-45
cable tester.
“Picture is fuzzy or edgy.”
1.Adjust the Cable Compensation control on the BVR-
25. This compensates for the increased capacitance on
longer Cat-5 cable runs and sharpens the video image.
2.Confirm the cable length. It is important to note that
the BVR-25 was designed for cabling no longer than
1000’ for standard component video or 300’ for a High
Definition signal. Cat-6 wiring will give the longest,
best picture.
“There is hum in the audio signal.”
1.Verify that the Cat-5 cable is properly terminated on
both ends.
2.Make certain that the system is wired with CAT-5
twisted-pair cabling.
3.Make certain there are not any cuts, pinches, or sharp
twists in the wiring, allowing a conductor to short to
ground (i.e. shield, conduit, cold water pipe, plenum).
“No +12 volt output”
1. Measure output with voltmeter.
2.Confirm amperage required for automation system.
Install relay if necessary.
3.The video signal feeding the BVR-25 is too low or un-
calibrated. Re-adjust gain and calibration controls.

Troubleshooting
“No Picture or Sound.”
1.Make certain the Power light is on the BVR-25 and the
power is on for the sending unit (i.e. BVD-20 or
BVH-20).
2.Verify that the RJ-45 termination on both ends of the
Cat-5 is correct. We all know this is easy to get wrong.
Use an RJ-45 cable tester to verify.
3.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.
4. Make certain display or monitor is compatible with
format of choice, i.e. 480P; 1080i; etc.
“No Power Light.”
1. Confirm that you are using the proper 12 VDC for the
BVR-25 and that the outlet has power.
“Horizontal bars across the screen”
1.Check the power grounding of the display device, the
video processor, satellite dish, cable box, and all com-
ponents in the video signal path. They should all be
grounded back at the electrical panel, not locally.
2.Make sure that the CAT-5 wiring going into your BVR-
25 is not running parallel with any high voltage AC
systems.
“Video picture scrambled or colors incorrect”
1.Confirm that the “Y”, “PB”, and “PR” connections are
correct.
Power Wiring
The BVR-25 operates with a 110 VAC to 12 volt DC wall
plug transformer (provided) that is terminated with a 5mm
jack that will plug into the front panel. We have conve-
niently labeled this jack “+12VDC Input”. Please note that
the 12 volt supply transformer provided with the BVR-25
is different than the 24 volt supply that is used with some
other AudioControl balanced line products. Therefore, be
careful to not use the wrong power supply. Please note that the
striped wire is positive (+) and the solid wire is negative (-).
Optional Rear Power Connection
As an option you can power the BVR-25 via connection
to a barrier block on the rear panel instead of the 5mm jack
on the front panel which allows for a cleaner trim-out of
System 4: Video signal being fed into BVD-20 and routed to multiple BVR-25’s
via daisy chain wiring

your installation. When powering the BVR-25 from the
rear, it utilizes a 2-pin barrier block, which will require you
to cut off the 5mm pin connector from the provided power
supply and terminate the wires directly onto the terminals.
Please note that the striped wire is positive (+) and the solid
wire is negative (-).
Remote Powering the BVR-25 via CAT-5
The BVR-25 can also receive power over the 4th pair
of wires in a single CAT-5 cable (Blue and Blue/White)
provided you are NOT already sending an audio or video
signal over these wires. To use this option you will need to
move both Remote Power Jumpers from the “AV” position
to the “PWR” position. In addition you will need to pro-
vide 12 VDC power over the 4th pair of CAT-5 wires that
runs to the BVR-25, which usually requires stripping out
the wires from the main loom. If you are providing power
from over 100 feet it is recommended that you utilize a
larger power supply (15 VDC/500ma) to offset any power
loss from the long CAT-5. You can purchase these power
supplies from most electrical supply companies. Please
note that a switching power supply with a 3-wire AC plug
will not work correctly.
Grounding
The BVR-25, like all AudioControl balanced line prod-
ucts, is designed to offer maximum isolation from radiated
signals that can creep into the video signal path and make
your pictures look funny (we are not talking about “Ha
Ha”). By design the BVR-25 has high input impedance to
levels are correct. While this procedure will not replace a
high level ISF type video calibration, it is a good starting
point.
Image Compensation: The Image Compensation control
on the BVR-25 equalizes the video signal to counteract the
effect of wire capacitance. In most cases the COMPENSA-
TION control should be set the same as the GAIN control.
If the GAIN control is set to the “5 o’clock” position, the
COMPENSATION control should be set the same. If the
image still appears to be too soft or too edgy, further adjust-
ing can then be done.

Adjusting the Controls
Properly setting the controls
on your BVR-25 will always
give you the maximum per-
formance. Although the unit
does come “pre-set” from the
factory with many of the inter-
nal enhancements at optimum
levels, we have no way of
knowing the exact length of
cable that you will be using.
Therefore, we have provided
a few simple controls to assist
you in the optimization of the
system:
Gain: Simply, this control
on the BVR-25 adjusts the
output level or gain on all
four of the RCA connections. To help with this adjustment
process we have also provided a Calibration Indicator LED
that triggers when there is a peak “white” signal level of
1 volt. Typically GAIN calibration can be made by turn-
ing on the processor’s OSD function which will most often
display either white on a black background or vice versa.
An ideal signal for calibration is a fixed image that is 50%
white and 50% black such as a “needle” or “checkerboard”
pattern on that comes with many video test generators. Ad-
justing the gain control will raise or lower the white levels.
The Calibration LED illuminates when the white signal
ground which minimizes the ground loops that can appear
in a coax wired system. However it is recommended that
you always make sure the structure you are in is wired to
the National Electrical Code. The NEC standards require
all ground wires to run back to the main panel prior to ter-
mination. We now return you to your regularly scheduled
manual text…
Signal Wiring
The BVR-25 operates using standard unshielded twisted-
pair (UTP) Category 5 (or better) wiring. Good wiring
practices will minimize the chance of noise pickup.
Make certain that you do not run any 110-240 volt power
wiring near or parallel to the CAT-5 signal cables as they
could radiate noise into the signal wires. You may pick up
AC hum. Tests have shown however that you will not pick
up songs from the group AC/DC. The
BVR-25 uses 12 VDC power, which
will not radiate into the signal wires.
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 light-
ing power supplies fluorescent lights,
dimmers, actuators, motors, and small
children.

Cat-5 Wiring
The RJ-45 connections on the BVR-25 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 10/100 Base-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-20 / BVH-20 to the BVR-25. Do not split or “Y-off”
the video signal coming out of your BVD-20 into multiple
BVR-25s as the video signal will be compromised. Use
the BVH-20 to drive multiple BVR-25s or you can “daisy
chain” from one BVR-25 to another if necessary. See page
13 for more information.
Daisy Chaining Multiple BVR-25’s
The BVR-25 has the ability to receive video and audio
signals over CAT-5 and then route them on to five maxi-
mum BVR-25’s. This allows for wiring in a daisy chain
format rather than the star method. If you are using your
BVR-25 in this manner you need to remove the “termina-
tion resistor network” from the socket on the rear of the
BVR-25 that is routing the signal to another BVR-25. The
last BVR-25 in the signal path MUST have the “R37” resis-
tor network inserted for the system to function properly.
12 Volt Output Trigger
The BVR-25 is equipped with a unique signal sensing
circuit that allows it to output a constant 12 volts (100ma)
which can be used to trigger remote mounted projectors,
activate a lift, lower a screen or trigger other automation
products. The presence of any Component (Y) or Com-
posite video sync signal at the RJ-45 inputs to the BVR-25
produces a sustained +12VDC on the tip of the Video Trig-
ger Jack.
