OEM Architech PS-525 User manual

RECTANGULAR 5 1/4" 2-WAY MTM SPEAKER PS-525 LCRS
5 1/4" LCRS
Congratulations! You have
purchased a high quality stereo
loudspeaker. When matched to
comparable electronic equipment,
expect years of quality high fidelity
sound. We are constantly striving
to provide the very best technology
has to offer.
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.
If you have any further questions
regarding this speaker which are
not answered by this manual,
please feel free to contact your
local dealer.
GENERAL DESCRIPTION
The 5 1/4" two-way LCRS
speaker has two magnetically
shielded 5 1/4" Woven Kevlar
woofers with linear long throw butyl
rubber edge surrounds. Pivoting 1"
lens-free aluminized ferro-fluid
cooled dome tweeters are utilized
for excellent high frequency
dispersion throughout the 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.
AMPLIFIER OPERATION
The 5 1/4" two-way LCR speaker
is equipped with a special
automatic polyswitch circuit which,
when overdriven, will automatically
restrict electrical current to the
tweeter to prevent damage. The
circuit will automatically re-engage
once the volume is turned down or
the problem is removed. This
normally takes about thirty (30)
seconds to occur.
The speaker will perform well with
amplifiers from 15 to 150 Watts
RMS. However, any speaker can
be damaged or its protective
circuitry engaged by any size
amplifier that is being 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. If you should find that
your protective circuits on the
tweeter are activated often, please
consider reducing the volume at
which you normally play the
speaker or purchasing a larger
amplifier with more reserve power.
DAMAGE DONE TO A SPEAKER
BY CLIPPING IS NOT COVERED
UNDER THE WARRANTY.
SPEAKER PLACEMENT
Placement of the Wall Mounted
Speakers in your room should be
carefully considered. They should
be located where they will provide
you with the best possible sound
and the greatest ease of
installation.
It is beyond the scope of this
publication to discuss all of the
various aspects of speaker
placement. Please feel free to
contact your dealer.
WIRING
To achieve maximum performance
from your new speakers, we
strongly suggest the use of special
low inductance stereo cable. There
are many good brands presently on
the market. The cable should be 16
gauge or larger. Speaker wire
smaller than 16 gauge, which is
sometimes clear coated, will
decrease your speaker’s
performance. The larger the wire
is, the better. For a proper and safe
installation it is important when
installing your speakers and/or
running wire through your house
that you adhere to all local codes
and regulations. We suggest that a
professional be consulted in order
to maximize your system’s
performance. The following,
however, are just a few
suggestions:
1. Try to keep the wire length to a
minimum. Runs of over 50 feet
should have 16 gauge or heavier
wire.
2. Avoid routing speaker cables
immediately parallel to electrical
cables. This will help reduce
hum and RF interference.———

Cut-out Dimensions

3. In securing your wire, do not
staple or nail through the
insulation. By doing so, a short
could occur in your wire and not
only significantly reduce your
system’s performance but
damage your electronics, i.e.
amplifier, as well.
4. Allow about 2 ½ feet of free wire
at the cut-out to aid in the ease
of installation of your speakers.
This is also helpful if you should
have to remove the speaker
from the wall again for any
reason.
5. In checking your speakers, make
sure proper phasing is
maintained. Simply put, this
means being sure the same wire
which is hooked to the positive
terminal of the amplifier is
hooked to the positive terminal
of the speaker. It is important to
check this on all speakers. If
one speaker is hooked up
incorrectly, or out of phase, the
quality of your bass will be
seriously impaired.
INSTALLATION
As the diagrams show, the
speaker utilizes a metal mounting
ring which, after tightening with the
screws provided, acts as a clamp to
hold the speaker in place.
To aid in speaker performance, a
fibrous material, such as fiberglass
or polyester fiber, may be placed
behind the speaker to help
eliminate unwanted sound from
being transmitted into adjoining
rooms.
Professional installers use quality
equipment. The better the
equipment, the better the installation.
Once you determine where you wish
the speakers to be placed, do the
following:
Using the paper template provided
and the proper equipment, cut the
appropriate sized hole in the wall
making sure that where you wish the
speakers to be placed will not be
obstructed by a stud or other material
hidden in the wall. On drywall, cuts
are best made with a keyhole saw.
If it was done correctly, you should
be able to reach the speaker wire
through the hole. Pull the wire out of
the wall and hook it up to the
terminals on the back of the speaker
assembly, observing polarity (+ & -).
Install the frame and mounting
ring assembly by passing the black
mounting ring through the cut-out as
illustrated above (see figures 1 & 2).
Next, verify that the speaker frame
fits into the cut-out. The white
frame should fit snugly and
smoothly in the cut-out hole.
However, if the hole should have
been cut a little too large, there is
an overlapping frame on the
speaker that will cover this.
Once the frame is in place, begin
alternately tightening the screws
until the mounting ring is up against
the back side of the wall board
being careful not to over tighten
(see fig. 3). Insert speaker into
frame and install the remaining
screws (see fig. 4). Start with the
inner pair of screws followed by the
top pair and then the bottom pair.
Be careful not to over-tighten.
