Unpacking the loudspeakers
Carefully unpack the loudspeakers and retain the carton and packing materials for
future use. If the speakers have been damaged in transit, please inform your dealer
immediately.
STEP 1
Speaker Placement and Room Acoustics
The Precision Acoustics Speakers has been designed for high performance in a wide
variety of settings, but here are a few helpful hints that will help maximize
performance and your enjoyment.
Rooms with different height, width and length are preferable for best low frequency
performance, but obviously you must work with the room available to you. If possible,
place the speakers so they are firing along the longest wall in order to most
efficiently fill the room with music. In other words, if the room is 10 feet wide and 20
feet deep, place them along the 10 foot wall. There will be less wall reflection and
therefore a more natural sound.
Main Speakers
Ageneral guideline for speaker placement is to set
up the space between speaker and listener at
approximately 1.5 times the distance between the
speakers. For example, if the speakers are ideally
placed a minimum of 6 feet apart, the best seating
position would be 9 feet away. The speaker should
be placed approximately a foot from the back wall
for ideal performance and soundstage depth, but
can be placed as close to the back wall as six
inches.
Center Channel
Acenter channel can be expected to reproduce as much as 60% of a movie’s
soundtrack, mostof which is dialogue. In order to maintain the effect of voices
emanating from the actor’s mouth, the center channel should be centrally located
between the left and right main channels and be placed above or below the television.
Surround Speakers
Surround speakers should be positioned adjacent to and slightly behind the primary
listening area. If they are to be wall mounted and positioned more than about 5 feet
from the listening area then they should be installed at a height of about 6 feet. If they
are to be placed on stands or in a wall unit closer to the listening area then they
should be positioned at roughly head level.
Subwoofer Placement
Asubwoofer should ideally be placed near your main channel speakers but the
omni-directional bass propagation allows placement almost anywhere in the room
and maintain optimum performance.
STEP 2
Wiring the speakers
Note: Please turn off your system prior
to making any connections.
To wire your system, please use good quality,
speaker grade audio cable with polarity coding
(usually identified with a marking on the
cable) as per the gaugerecommendations
indicated below. The side of the cable that has
the coding (a ridge, or "+" marking) usually
denotes the positive polarity.
Connect the positive lead of the speaker wire (indicated with a "+" or other
marking) tothe Red (or positive) speaker terminal. Connect the other speaker
wire lead to the Black (or negative) speaker terminal. Connect the opposite end of
the speaker wire to your amplifier making sure that the polarity is preserved ("+"
to "+" or Red to Red, and "-" to "-" or Black to Black – see diagram).
STEP 3
Listening Test
Once you have connected your speakers,
turn on your system and begin playback
of material you are familiar with. Begin
at low volume and increase to a
comfortable listening level. The system
should sound balanced with good stereo
imaging. If the imaging sounds distorted
and confused, check to make sure that
the speakers have been correctly wired
with your amplifier/receiver as indicated
in Step 2.
Maintenance
Your Precision Acoustics loudspeaker
cabinets are finished with a high quality
vinyl that requires very little
maintenance. Simply use a damp cloth
to remove dust and fingerprints, and
avoid all use of chemical products and
polishes on the cabinet and grille.
