UNPACKING
Remove the V-80 from its packing
carefully and inspect it for any ship-
ping damage. If you discover damage,
contact your B.I.C dealer immediately.
If possible, save the carton and
internal packing. It’s the best possible
protection for your V-80 if you need
to move it or return it for service.
Next, fill out the Warranty
Registration card and return it to us.
Finally,
keep your sales receipt in
a secure place.
It helps establish the
duration of your warranty and is good
for insurance purposes (just in case
anything happens to your stereo
system).

A
PLACEMENT
Where to put your V-80
The V-80 operates mostly at
frequencies below 100Hz. These low
bass frequencies are essentially omni-
directional. That means you can place
the V-80 almost anywhere in a room
without compromising the effective-
ness of your main stereo speakers.
Three factors need to be consid-
ered:
1)
distance from a wall outlet;
2)
distance from your receiver and;
3)
proximity to walls and corners.
1. Wall outlet.
Since the V-80
requires AC power, it must be placed
within six feet of wall outlet. We don’t
recommend extending that range with
an extension cord.
2. Connections to your receiver,
integrated amplifier or preampli-
fier.
If your receiver or integrated
amplifier does not have pre/main con-
nections (see next page), hookup
between the amp and V-80 will be
made with speaker wire. You can
B
basically place the V-80 anywhere in a
normal-sized room.
3. Proximity to walls and
corners.
Physical placement of the
subwoofer will have a definite impact
on the frequency response and the
perceived amount of V-80 bass output.
Because low frequencies have long
wavelengths, they are influenced by
proximity to a boundary such as a wall
or floor.
See Drawing 1 below. When you
place the V-80 well away from a wall,
it will produce bass at a certain level.
Move the V-80 close to the wall, it will
produce more output (about 3dB
more). Putting the subwoofer in a
corner will increase output another
3dB (6dB more than when placed
away from walls and corners).
All this technical jargon may sound
confusing, but it basically means that
you have a number of options, each of
which produces a different amount of
bass. For example, if you like a lot of
heavy bass, consider putting the V-80
into a corner. If you like smoother,
less-obvious bass, move the sub-
woofer out into the room. The main
thing to remember is that there is no
“right” or “wrong” place to put the
V-80 (assuming it’s less than six feet
from a wall receptacle). It all depends
on how much bass you want.
Another reason to experiment —
because low bass waves are very large
(up to forty feet or more across!), they
tend to cancel and reinforce each
other, causing places in the room
where there is lots of bass and others
where there isn’t very much at all. If
you walk around your listening room
while playing music, you’ll probably
discover these sorts of areas where
bass is either exaggerated or reduced.
Needless to say, if your main listening
area ends up in a “dead” space, you
will need to move the V-80 so that
bass is more normal.
Incidentally, moving the V-80
around won’t affect the stereo imaging
of your main stereo system, so feel
free to try various subwoofer positions.
Connecting the V-80 to
a wall plug
The V-80 draws a moderately high
amount of current. We do not recom-
mend plugging it into a “convenience”
outlet (switched or unswitched) that
is often found on the back of receivers
and other stereo components.
Instead, connect the V-80 ONLY to
its own AC outlet. See items 8 and 9 in
the Safety Instructions at the beginning
of this manual.
