OEM Presence Elite PE-620LCRSf User manual

INSTALLATION GUIDE
Congratulations! You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic
equipment, expect years of quality high delity sound. Our
belief is that music matters and we are focused on delivering
superlative music reproduction everywhere in your home.
The following manual is designed to give you, the installer
or owner, basic information as to the speaker’s installation
and operation. It is beyond the scope of this manual to go
into all the details that must be taken into consideration in a
sophisticated high delity system. When installing the wiring
and speakers it is important to adhere to all local codes and
regulations. Consulting a professional can help to maximize
your system’s performance.
If you have any questions regarding this speaker which are
not answered by this manual, contact your local dealer for
assistance. For the most current information please visit

GENERAL DESCRIPTION
These two-way speakers have specially designed woofers
with linear long throw butyl rubber surrounds for long life and
superior damping. Dome tweeters are utilized for excellent
high frequency dispersion throughout your entire listening
environment.
SHIPPING DAMAGE
Each speaker is thoroughly tested before it leaves the
factory. However, in shipment, accidents may occur. Please
inspect your speakers carefully when you receive them to
make sure there is no damage. If there is, please notify your
dealer or supplier immediately for assistance. If you received
your speakers by public transportation, report the damage
immediately to the shipping company.
AMPLIFIER OPERATION
These speakers will perform well with ampliers from 5 to
125 Watts RMS. However, damage to the speakers can be
done by ampliers of nearly any power rating if the amplier
is overdriven into clipping. “Amplier clipping” is a phrase
used to describe a condition when, because of the volume
demand, an amplier is being asked for more power than it
can give. Clipping causes distortion of the audio signal. If you
should hear an unusual amount of distortion at high listening
levels then consider reducing the volume. DAMAGE DONE
TO A SPEAKER BY CLIPPING IS NOT COVERED UNDER THE
WARRANTY.

SPEAKER PLACEMENT
Placement of in-ceiling and in-wall speakers should be
carefully considered. Please contact a professional for
assistance if you are uncomfortable with the planning or
installation process.
Ideally, the speakers should be located where they will provide
the best possible sound and ease of installation. It is beyond
the scope of this publication to discuss all of the various
aspects of speaker placement, but here are some helpful
suggestions.
For the front channels of a home theater we recommend that
the speakers be placed between 18 and 36 inches (0.45m
to 0.9m) from an adjacent wall/surface, as measured to the
center of the hole. Avoid placing the speakers less than 12
inches (0.3m) from an adjacent wall. When placing speakers
near a corner, avoid locating them an equal distance from the
two adjacent surfaces.
If the drywall has not yet been installed, rough-in-kits are
available to reserve the speaker location. The hole is then cut
when the drywall is installed.
WIRING
To achieve maximum performance we recommend that the
speaker cable be at least 16 gauge or larger for runs over 50
feet (15m) and that the cable be double insulated. A CL-2 or
CL-3 rated cable may be required. Check local codes. “Zip
cord,” which is single insulated and is often made with clear
insulation, should be avoided as it is not as durable. Allow
about 2½ feet (0.8m) of free cable at the speaker cut-out and
sufcient length at the other end to reach the electronics.
Having to add extra cable later can be tedious and time
consuming.
Avoid bundling speaker cables parallel to electrical cables
for extended lengths. Though the impedance is low and the
likelihood of interference low, this may help reduce hum and
RF interference. When securing the cable, use care not to
staple or nail through the electrical conductors. Doing so
could result in a short that might damage the electronics.
When connecting your speakers, make sure proper polarity
(phasing) is maintained. Simply put, this means ensuring the
same wire which is connected to the positive terminal of the
amplier has its other end connected to the positive terminal
of the speaker. It is important to check this on all speakers. If
the connections on one of the speakers are reversed, (out of
phase) the sound quality will be impaired.
INSTALLATION
If the speaker locations have not yet been established then
do so now. If possible, assess the area behind the ceiling
for possible concealed obstructions such as wiring, heating

ducts, cross-bracing etc. Absence of a crawl space will require
greater study of observable clues and may also require the use of
inspection holes and inspection tools (camera, mirror, ashlight,
etc.). Use an “electronic stud nder” to locate the positions of
the joists or studs. We recommend that the edge of the speaker
holes be at least 3/4" (19mm) away from joists or studs whenever
possible to allow clearance for the toggle clamps.
Once the speaker locations are established use the cardboard
template or the plastic compass provided with your speaker to draw
the speaker cut-out. The hole diameters for the various speakers
are marked on the compass. The cardboard templates may also
be used as a visual aid for placement of the speakers. To do this,
temporarily hold the templates in place with a push tack or tape.
Using the proper tool, cut the appropriate sized hole in the ceiling.
On drywall, clean cuts can be made with a drywall saw. Make sure
to clean the excess debris from the front face of the hole to ensure a
ush t.
If the cable has not yet been run, do so now that
you have better access to the ceiling. Once the
speaker cable has been run, pull the end of the
cable out of the speaker cut-out, strip back a
section of the jacket as needed, and then expose
½" (13mm) of each conductor.
To aid in speaker performance, a brous material, such as
berglass, may be placed behind the speaker. This may also help
to reduce unwanted sound from being transmitted into adjoining
rooms. If the ceiling space has blown or loose insulation, care
must be taken to prevent the loose insulation from entering the
back of the speaker. This can be accomplished by placing a batt
of berglass insulation, fabric barrier,
or bag over the back of the speaker.
Alternatively you may use an Insu-
Flate ISF-147, which is an acoustically
transparent fabric cover specically
designed for this application. Placing
a rigid enclosure behind the speakers
can be done but the enclosure should
be large enough not to degrade the
performance of the speaker. Rigid enclosures of less than 0.75
cu ft (21 liters) should be stuffed with acoustic insulation such as
berglass.
As the drawing shows, the speakers utilize
Toggle Clamps which, after tightening,
hold the speakers in place. Ensure that
the toggle clamps are rotated into their
“Home” position prior to installation.
Verify that the speaker ts properly into
the cut-out and then remove the speaker
from the hole.
Connect the wire conductors to the terminals on the back of the
speaker by depressing each spring terminal, inserting the wire into
the hole, and releasing the terminal. Use care to observe the proper
polarity (+ & -). Speakers wired out of phase will exhibit an apparent
loss of bass response.
This speaker is optimized for off-axis listening through the use
of a pivoting tweeter and a 15 degree bafe tilt. We recommend
directing the woofer and tilting the tweeter toward the listening
position. USE
CARE TO AVOID
DAMAGING THE
DOME OF THE
TWEETER WHEN
AIMING!
Insert the speaker
into the hole and
turn each screw clockwise. The toggle clamps will rotate outward to
engage the ceiling material as shown. Before tightening the three
screws, orient the speaker toward the listening area. Tighten all
the screws. CAUTION: DO NOT OVER-TIGHTEN THE CLAMPS. Too
much torque may damage the toggle, causing the speaker not to
seat securely. A snug t is all that is necessary to assure proper
performance.
Attach the grilles to the speakers and enjoy. Should you wish
to remove the grilles from the speakers pull at the grilles' edge.
Initially there will be a signicant resistance because the grilles are
magnetically attached.
The grilles can be painted using multiple light coats of spray paint.
Custom color spray paints are available from specialty companies.
Contact your dealer for more information. The grilles should be
removed from the speaker and painted in a clean environment to
prevent contamination. It is best to go around the grilles and apply the
paint from multiple angles. DO NOT remove the scrim cloth from the
backside of the grille. It is not replaceable.
