OEM Presence A-505 Installation Manual

Presence
Congratulations! You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic
equipment, expect years of quality high fidelity sound. The
Presence brand is based on the belief 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 fidelity 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 at once to the shipping company.
AMPLIFIER OPERATION
These speakers will perform well with amplifiers from 5
to 125 Watts RMS. However, damage to the speakers can
be done by amplifiers of nearly any power rating if the
amplifier is overdriven into clipping. "Amplifier clipping"
is a phrase used to describe a condition when, because of
the volume demand, an amplifier 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. However, here are a couple quick
suggestions. For more bass we recommend that the
speakers be placed between 18 and 36 inches from an
adjacent wall/surface, as measured to the center of the
hole. Avoid placing the speakers less then 12 inches 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 cut
when the drywall is installed. The cable can be tied off on
the rough-in-kit after securing it to a nearby joist.
WIRING
To achieve maximum performance from your new
speakers we strongly suggest the use of good quality
stereo cable. We recommend that the cable be at least 16
gauge or larger for runs of over 50 feet and that the cable
be double insulated. This is often referred to as "jacketed"
speaker cable and CL-2 or CL-3 rated. "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
sufficient 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 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
being sure the same wire which is hooked to the positive
terminal of the amplifier has its other end hooked to the
