Warranty Coverage
For Your Records
The LU47 series speakers are
speaker and will deliver accurate high fidelity sound in
exterior or interior environments. Weather-resistant
design and construction provide optimum durability for
permanent or temporary outdoor use. Both models are
available in black or white.
For simplicity, we will call your AV receiver or amplifier
the “receiver.”
The grilles are not designed or intended to be removed. Do
not remove the grilles from your speakers. There are no
user-serviceable parts behind the grille and removal will
damage the speaker.
You must have proof of purchase to receive warranty service.
Please keep your original sales receipt and be prepared to
provide this receipt in the event you require service, as your
original receipt is considered the best proof of purchase and
indicates the date you purchased your Dual product.

LU47PW-LU47PB INSTALLATION
Placement & Mounting Speakers
The LU47 series speakers have been tested fo
resistant, but not waterproof. Occasional moisture will not affect performance. The
speakers should be allowed to ventilate and dry after water exposure.
The speakers can be placed permanently outdoors for yea
speaker life, position in areas protected from the elements, such as the underside of eaves
and overhangs. Popular locations include decks, gazebos, porches, atriums, garages, and
covered spa areas. For temporary placement, remove the speaker from the mounting
brackets and replace the thumb screws to maintain stability if placing the speakers on end.
The LU47 series speakers have a Dual logo that can be rotated. The logo is located on the
face of the grille in the event a vertical installation is needed. The logo is spring loaded. Use
gentle force when adjusting the logo to a new orientation. To rotate the logo, elevate two
ends of the logo equally by placing your nail under and lifting lightly. While the logo is
elevated, turn the logo to the desired orientation and release.
Mounting Your Speakers
For ease of installation, the LU47 series speakers include
bracket. Once mounted, the bracket allows the speaker to be pivoted to its ideal location.
The included thumb screws knobs will hold the selected speaker position when properly
tightened. Avoid over tightening the knob. Before attempting the installation, carefully
evaluate the mounting surface, making sure that its composition and construction are
strong enough to support the load safely. If you are unsure about the type of mounting
hardware for your installation, consult a professional contractor or a knowledgeable
hardware store. The anchors and screws to attach the speakers are not included and must
be purchased separately. The hardened steel brackets are suitable only for attaching the
speaker to walls or ceilings constructed of solid wood, brickwork, concrete, hollow
buildings block or wood studs.

LU47PW-LU47PB CONNECTION
Connecting Speakers
®
Connecting
Your Speakers
Speaker Wire -Typical speaker wire has a pair of separate
speaker wires with insulating jackets that are molded
together. Dual recommends the use of two conductor 18gauge speaker wire to connect your speakers to your
receiver. Measure enough wire to reach from your receiver
to each speaker plus additional length to allow moving the
speakers or receiver without having to disconnect the wires.
When connecting the speakers in a stereo configuration, the
wire length should be similar. One length should not be
dramatically longer or shorter then the other. Maintaining
similar wire lengths will provide superior sound quality.
Polarity - Speaker wires are marked for polarity consistency
so that you can determine the positive and negative identity
of the individual wires within the molded pair insulation.
Polarity is shown by either a color stripe on the insulation,
by ridges molded into one side of the insulation, the color of
the insulation case around the wire, or by the colortype or
colors of the wires/wire itself (copper or silver).
Important - Always connect speaker wire using the positive
(+) terminal on the receiver to the positive (+) terminal, and
the negative (-) terminal on the receiver to the negative (-)
terminal. All speakers in a system must be connected with
the same respective polarity. The speaker inputs are
located on the rear-mounted terminal cup on the back of the
speaker.
Terminal Type - The LU47 series utilizes a push-pin design.

LU47PW-LU47PB CONNECTION & TROUBLESHOOTING
Connecting Speakers
Your Speakers
Distortion/Knocking
The speaker wires must be inserted into the connector
and tightened properly
over-tighten. Do not allow the positive and negative
speaker wire from the receiver to make contact, as this
will cause a short. Banana style connectors may also be
used on the LU47PB. The connection is made by
connecting the speaker wire to the banana plugs, and
then inserting the banana plug into the top portion of the
binding posts.
It is recommended that the wire insulation be stripped back
approximately 3/8”, allowing the wire conductor to make
a proper connection. Make sure that the wire insulation
is stripped back far enough so that the bare speaker wire
will make a proper connection to the metal clip inside
the terminal and be securely held in place. This can be
confirmed visually.
to the speaker inputs. Do not
Troubleshooting
If you hear obvious distortion from the speakers, immediately
lower the volume level of your receiver. Those sounds often
indicate that either the receiver or the speaker is being
overdriven, and damage can result in playing your source
material (music-CDs-DVD-MP3) at high volume levels for
prolonged periods of time. You should also avoid turning the
bass or treble controls fully up and using your "Loudness
button" when the volume level is at or above normal listening
levels. Note: The Loudness button on most receivers is
designed to add depth when your system is being used for
background music or at very low volume.
Distorted or unnatural sound can indicate poor connections,
defective electronics, damaged source material or speaker
failure. If only one of your speakers has poor sound quality,
check the speaker wire and audio connections. If that doesn’t
fix the problem, try putting each speaker in place of one
another (swapping). If the sound remains poor on the suspect
speaker after swapping location and the distortion moves
with the speaker to the new location, the speaker may be the
problem. If the distortion remains in the original location then
the problem is eleswhere in your audio/video system.
