OWNER’S MANUAL
Thank you for choosing DCM Time Out Loudspeakers
DCM WARRANTY INFORMATION
All DCM speaker systems are designed to provide high fidelity, long life and installation convenience for commercial and residential applications. Because of their weather
resistant properties, you can use them indoors or outdoors- wherever great sound is
desired. For information on our other products, go to www.dcmspeakers.com or call
1-800-DCM-LOUD.
DCM Loudspeakers purchased in the United States from an authorized DCM dealer
are guaranteed against defects in material and workmanship for a period of five years
from the date purchased by the end user, and limited to the original retail purchaser
of the product.
PLACEMENT
Outdoor use:
The materials used in the construction of the DCM Time Out Speaker systems are
weather resistant for use in even the harshest conditions. The hardware is brass, the
grille is powder-coated aluminum, and the bracket is zinc plated, powder coated steel.
The enclosure itself is shatter-resistant. Adhering to just a few mounting guidelines will
further extend the life of the product.
Whenever possible, mount the speaker under an eave or other protective overhang.
Always aim the speaker at a slight downward angle to prevent water from accumulating
on the speaker cone.
Do not place the speaker in a location where water, snow or ice will accumulate on the
speaker for extended periods of time.
Indoor Use:
The DCM Time Out Speaker systems works very well when it is wall mounted in
indoor applications. When you place the speaker on a wall, you take advantage of the
natural boundary effect that occurs when a speaker system is placed against one or
more surfaces. This boundary effect will provide increased overall output. When you
mount the speaker against one surface (on a wall) you increase output by 3dB. When
you mount the speaker against two surfaces (on the wall near the ceiling) you increase
the output by 6dB. When you mount the speaker against three surfaces (in a corner
near the ceiling) you increase the output by 9dB. Please note that the TO52-B and
TO82-B include magnetic shielding (bucking magnets) to minimize interference when
placed near CRT monitors.
Shelf Mounting:
The bottom surface of the TO52-B and TO82-B is sloped to maintain level orientation when shelf mounted.
Down Firing:
The DCM Time Out Speaker systems also work well in a down firing configuration
for spaces utilizing open beam ceilings such as offices, restaurants and warehouses.
When determining speaker spacing in down-firing installations you can use the following chart:
TO52-B =120o nominal coverage (60o off axis) at 2 kHz

Installation
Fixed Install:
The DCM Time Out Speaker systems include a versatile yet simple U-bracket
designed to provide easy vertical or horizontal installation on just about any surface.
The speaker may be installed using screws or bolts placed through the “L” shaped
holes in the mounting bracket. The center 5/8”-27 hole allows wires to exit through the
bracket when wall mounting, for a neat installation. The unused inserts on the bottom
of the cabinet (TO82-B) or rear of the cabinet (TO52-B) may be used with standard
1/4”-20 forged eyebolt and an approved safety cable (wire rope sling) where redundant
support is required for seismic considerations. These parts are available through many
sources including Grainger Corporation. (www.Grainger.com).
Size 21, 1/4” X 1” Forged Eyebolt- Grainger Part Number: 2G692
Galvanized Steel Cable Spool, 1/8”- Grainger Part Number: 4KH26
Sleeve N ThimbleTM Kit for 1/8” Cable, -Grainger Part Number: 4KH28
Swage It Tool for 1/16”, 3/32”, and 1/8”- Cable Size- Grainger Part Number: 4KH08
The mounting knobs included with the speaker product may be easily interchanged
with standard, 1/4”-20 vandal proof hardware. Grainger Corporation is also a good
source for torx head, spanner head or one-way security bolts. (www.Grainger.com)

When you have an installation challenge that the U-bracket will not accommodate,
we suggest you contact our friends at OMNIMOUNT systems (www.omnimountsyste
ms.com) to select one of their quality swivel mount products (25 Series for TO52-B, 75
Series for TO82-B).
Overhead Suspension:
Caution: Suspending any object is potentially dangerous and should be attempted
nected. Most consumer amplifiers are rated to operate at a 4 ohm minimum output
impedance per channel (Check the back panel of the amplifier or the amplifier owners
manual to verify). With this arrangement, (2) TO52-B/TO82-B speakers may be connected in parallel to each channel of the amplifier (two 8 ohm speakers per channel=
a 4 ohm load). (See Fig. 1).
only by individuals who have a thorough knowledge of the techniques and regulations
of rigging objects overhead using ONLY hardware approved for this type of installation.
DCM strongly recommends that surface mount enclosures only be suspended overhead when taking into account all current national, federal, state, and local regulations.
It is the responsibility of the installer to insure that the speaker is installed according
to those regulations. If the speaker is suspended, DCM strongly recommends that
the system be inspected at least once a year. If any sign of weakness or damage is
detected, remedial action should be taken immediately.

Near Field Live Sound Monitoring
A standard 5/8”-27 thread insert is included on the U-bracket to facilitate mounting
on Atlas Sound microphone stands for use as a near-field live sound monitor.
Painting the Speakers:
The injection molded, polypropylene, talc impregnated cabinets can be painted to
match your decor. You should prime the cabinet with two coats of a product such as
KrylonTM Sandable Spray Primer #1318. You may use oil or water based house paint
or spray paint. (Be sure to use appropriate exterior house paint for outdoor applications).
1. Remove the grilles and brackets
2. Mask the speaker components and input terminals area with newspaper and masking tape.
3. Apply two thin primer coats to the speaker cabinets and knobs. (The brackets do not
require a primer coat.)
4. After the primer coats are completely dry, paint the cabinets, brackets and knobs. Be
careful not to paint the input terminals.
Painting the Grilles:
Remove and paint the grilles before inserting them onto the frames:
TO52-B: Using a paper clip bent into a “hook” shape, insert it into a grille near the
corner and pull the grille away from the cabinet.
TO82-B: Remove all screws around the outside of the grille to remove the grille from
the cabinet.
Apply (2) thin coats of paint (primer is not required) be careful not to let the paint clog
the holes in the grilles.
Connections:
TO52-B/TO82-B
The TO52-B and TO82-B loudspeakers include (1) 5-way binding post and (1) 1/4”
phone jack. Both inputs are paralleled together to allow daisy chaining with the twoconnector types. The binding post is designed to accept up to 12#awg stranded cable
or standard MDP style banana plugs.
Amplifier limitations will dictate how many TO52-B/TO82-B speakers may be con-

Be sure to use a good quality, unshielded twisted pair speaker cable to connect the
amplifier to the speaker(s) (#14AWG for runs <80’, #12AWG for runs >80’).
Standard ZIP style speaker cable may also be used if twisted pair cable is not available.
DO NOT USE SHIELDED INSTRUMENT STYLE (Guitar) CABLES TO CONNECT
SPEAKERS.
When making the connections, be sure to maintain proper polarity between speakers. (Red wire to red terminals- black wire to black terminal where applicable).
Maintenance and Care
Your DCM Time Out loudspeakers have been designed and manufactured for years
of trouble-free service. You can clean your loudspeakers with a dampened soft cloth
or paper towel. If the speaker is mounted high on a wall or ceiling, use a broom or
duster to gently brush it off. Spraying the speaker with a high-pressure water is not
recommended.
