Product Description
The 12.1P is a self contained, powered 12" subwoofer providing over
300 watts continuous output to the speaker. The 12.1P makes the
addition of a subwoofer to a VID system very easy and efficient. Since
the unit is self-powered, the full range satellite speakers can be powered
independently from the subwoofer and optimized for the installation.
The 12.1P features a high performance, variable, 12-dB/octave
crossover and a full range line level output along with a high pass line
level output on the rear panel. The unit can be mounted in a variety of
configurations with the bracket hardware supplied.
Product Feature Identification
The 12.1P subwoofer comes with a dual-mode mounting bracket that
enables the unit to be easily mounted at either a wall/wall (corner) or on
a wall/ceiling (midwall) junction. The included forged steel eyebolt
provides the installer a solid attachment point for a safety line. When
properly anchored and supported, the 12.1P subwoofer may also be
safely installed protruding just 2 3/4" down through a standard sus-
pended ceiling grid. See installation instructions.

Step-by-Step Installation & Wiring
Step 1: Mount the Bracket
The mounting bracket can be installed two ways (see Figures 5 and 6),
allowing optimal configurations for installations. Leave 1.5" of space
between the bracket and the ceiling when installing in a corner! Attach
the bracket to the wall with suitable fasteners screwed into structural
members in the wall. Remember: It is the installers responsibility to
insure that the structure can safely support the load.

Step 2: Install the Safety Line
Using accepted safe rigging practices, secure one end of a suitable
safety line (use cable, not chain, which will rattle) to a strong, secure
point above the speaker, a point that can withstand the shock of the
falling speaker. This is especially important in public spaces constructed
with light gauge steel studs. Do not attach the safety line to the bracket!
The safety line should prevent the speaker from falling if the bracket
tears loose from the wall. Secure the other end to the eyebolt that is fully
threaded into the enclosure.

Figure 7: Wiring Configuration
Step 3: Wire the Speaker
A typical wiring configuration is shown in Figure 7. It is highly advisable
to support the unit while these connections are being made. When
mounting the speaker in a corner mount configuration, a right angle XLR
connector such as Neutrik #NC3MRC or equiv. is required for the signal
connections (see Figure 7). Connect the line level signal from the mixer,
pre amplifier or other source into the line input connector. Plug in the
power cord and connect the unit to a standard 120VAC power source.
The proper crossover setting is
determined by the satellite
speakers used. The following
are general guidelines:
Adjust the crossover according
to the chart above. Set the
appropriate sub level before
making the final mounting to the
bracket.
Step 4: Mount the Speaker to the Bracket
First remove the two Phillips-head screws on the rear of the enclosure.
Use the supplied eyebolt to mount one mounting clip to the top of the
speaker as shown in Figure 8. Check to make sure that the wiring
connections to the amplifier and the satellite speakers are correct and
secure.
For corner mounting
Attach the four rubber mounting feet to the front side edges, and secure
the safety line to the eyebolt. Lift the enclosure up to the ceiling and
center it back it into the corner until it touches the bracket rungs, then
carefully lower it so the top clip hooks over the top rung of the bracket
(1). Insert one of the 3/8-16-thread Phillips-head screws through the
remaining clip and, with the clip pointing up, thread the screw finger-tight
into the lower mtg. hole on the enclosure (2, 3). Level the clip and tighten
securely with a #3 right-angle Phillips screwdriver. ven though the

enclosure hangs from the top clip, always install the lower one to secure
against possible disengagement of the top clip. Straighten the V® logo
and press firmly at its center to seat it securely into its mounting hole.
For midwall mounting
Attach the four rubber mounting feet inside the corners on the side of the
enclosure that will be against the wall and attach the safety line to the
eyebolt. Insert one of the 3/8-16-thread Phillips-head screws through the
remaining clip and keep it within arms reach. Lift the enclosure up to the
ceiling and bring its back into contact with the bracket rungs. Slide the
enclosure sideways to engage the clip over one bracket rung (1) and,
while holding it tight against both rungs, insert the 3/8-16-thread screw
with its clip into the remaining mounting hole so the clip engages the
remaining bracket rung (2, 3). Finger-tighten the screw and straighten
the clip. The enclosure may now be released. It will slide down the rungs
until the four rubber feet are snug against the wall. Using a #3 right-angle
Phillips screwdriver, securely tighten the second Phillips-head screw.
Gently rotate the V® logo a quarter turn and press firmly at its center to
seat it securely into its mounting hole. See Figure 9.

Mounting through a suspended ceiling grid
On the rear of the enclosure install and tighten two 3/8-16-thread forged
steel eyebolts (one is included) with a 3/8" flat washer under each. Cut
two pieces of ordinary drop ceiling L angle (wall track) 23 3/4" long and
screw them to the top and bottom of the enclosure with 3/4"-long sheet
metal screws, as shown in Figure 10. Connect all of the wires and
suspend the enclosure, face down, by the eyebolts in accordance with
accepted safe rigging practice. Adjust the length of the rigging cables so
the tips of the installed L angles just rest on the ceiling cross-tees. This
stabilizes the enclosure from rocking. Trim the ceiling panel to fit the new
opening(s) and drop into place. It is the installers responsibility to assure
that the chosen rigging points are strong enough to support the load.
Warning Never try to install this speaker in a suspended
ceiling without proper rigging support!
Floor Mounting
The VID 12.1P may be placed directly on the floor in a corner or on
its side along a straight wall by simply attaching the four rubber mounting
feet to the side that will sit on the floor.
Step 5: Test System peration
After all connections are made test the complete system operation.
Appendix C on page 10 contains a troubleshooting guide to assist in
locating a variety of speaker related problems.

Appendix B: Installation
Exa ples
The VID Series is a product family with the flexibility to fit the
requirements of many different applications. Listed below are some
suggested combinations for systems using the 12.1P with VID full
range speakers:
•Rich, full-sounding low-level background music and paging in a
quiet restaurant, office, or retail space: use two VID 3.2s or
C4.2s for each 12.1P installed.
•Moderate-level music and paging in a sports bar/restaurant or
upbeat retail space: install two or four VID 4.2s or C8.2s for
each 12.1P used.

Electro-Voice® EVID 12.1P User Manual

•Higher-level foreground music in bass heavy applications such
as dance floors, amusement arcades, or loud bars: use one pair
of VID 6.2s for each 12.1P.
•For example, a large hotel might use eight 3.2s and two 12.1Ps
in the dining room, eight 4.2s and two 12.1Ps in the lounge, four
6.2s with two 12.1Ps surrounding the dance floor, 6.2s around
the pool, 6.2s or 4.2s with or without 12.1Ps in the lobby, and
3.2s in the corridors.
Characteristics of All Subwoofers
While subwoofers do radiate sound omni-directionally (in all directions)
and the sound is generally non-localizable (one cant hear exactly where
it comes from), subwoofer sound level still drops off the farther one
moves from the subwoofer. The highest output and best room loading
are accomplished with the subwoofer mounted in a corner at a three-
boundary junction (wall/wall/ceiling or wall/wall/floor, an arrangement
also referred to as 1/8 space). Mounting at a two-boundary junction (wall/
ceiling, or 1/4 space) produces three dB less output, and mounting in the
middle of a room in the ceiling (1/2 space) reduces output still another
three dB.
Subwoofers produce large amounts of long wavelength low-frequency
energy. very object has its own resonant frequency, and long
wavelengths tend to excite large objects (like walls, floors, doors and
ceiling panels). Anything loose in or on a ceiling or wall will buzz or rattle
as a subwoofers level is increased. Most of these can be isolated and
fixed with small, strategically placed bits of foam tape. Others may
require driving additional nails or screws and perhaps some caulking to
dampen their sympathetic movement.

Appendix C: Painting Process
•Remove the four screws securing the front hatch and lift off the
hatch panel. Carefully twist and lift off the V® logo and set it
aside.
•The foam grille blocks are held in place by sharp pins protruding
through the baffle board. Note the relative position of the foam
and carefully lift the blocks off the pins. Mask around and over
the amplifier panel with tape and heavy paper and tape a piece
of heavy paper over the woofer. It is not necessary to remove
any components.
•Clean the cabinet, bracket and clips by rubbing with a lightly
dampened cloth. Do not use abrasives such as sandpaper or
steel wool. Never use gasoline, kerosene, acetone, M K, paint
thinner, harsh detergents, or other chemicals, as these agents
may cause permanent damage to the enclosure.
•After cleaning, apply two or more two thin coats of either latex or
oil-based paint. Spraying is recommended, but a brush and
small roller work very well. It is not necessary to paint all the way
up to the woofer. Only the visible surfaces need to be painted:
the hatch front and side edges, the exposed enclosure surfaces
down to the hatch gaskets and about halfway under where the
foam blocks sit. Likewise, the rear sides of the bracket and clips
need not be painted. The hatch screw heads may be painted, if
desired.
•When the paint is thoroughly dry, carefully unmask everything.
Replace the foam blocks, pressing them gently down onto the
sharp pins. Replace the hatch cover and tighten the four screws.
Locate the small center hole, properly orient the V® logo, and
press it firmly into place at its center to reseat it in the mounting
hole.

Appendix D: Troubleshooting
Guide
Problem Possible Cause(s) Action
1. No sound A plifier Verify that that the line level signal cables
XLR connector has been pushed all the way
into the Low Level In jack on the a plifier
panel. Turn the Power switch on and the
volu e up until you can hear sound e itting
fro the 12.1p subwoofer. If there is still no
sound, the proble is with the line level
signal.
Line level signal Connect a known working powered test
speaker to the line level signal fro the
ixer, pre a plifier or other source. If there
is no sound, check that all of the electronics
are on, the signal routing is correct, the
source is active, the volu e is on and so on.
Fuse Carefully re ove the fuse holder fro the
power cord input with the use of a flat head
screwdriver. Inspect the fuse for any
da age. Blown fuses will typically show a
s oke-like blackening on the inside of the
glass. If this is the proble , replace the fuse
with a 4A/250V, 20 x 5 fuse.
Only replace this fuse with the same type
and rated fuse to reduce the risk of fire.
2. Poor low-frequency Speakers wired When two speakers are connected out
response out-of-polarity of polarity (out of phase), the low frequencies
will cancel each other acoustically. Carefully
observe the wire arkings or tracers on your
full-range speaker wires. Verify that their
a plifier (+) ter inal is connected to the red
speaker ter inals and their a plifier (-)
ter inal is connected to the black speaker
ter inals.
3. Inter ittent output Faulty Check the low-level signal cable/XLR
such as crackling or connection/wiring connector to ake sure that it has been
distortion pushed all the way into the Low Level In
a plifier panel jack. If crackling persists,
re ove the signal cable fro the a plifier
and its low-level signal source and check for
a faulty connection between the connector
and the cable. Make sure that all of the
ter inals on cable connectors have been
properly soldered.
If these suggestions do not solve your problem, contact your nearest Electro-Voice
dealer or Electro-Voice distributor.
