Sonance Quintette 521QR - Manual

INTRODUCTION
Thank you for purchasing Sonance Quintette™ in-ceiling speakers. When
properly installed, these speakers will give you many years of entertainment
pleasure. To get the most out of your new speakers, please read this
manual thoroughly before you begin installation. This manual covers
the Quintette 522
QR and 521 QR speaker models.
PARTS LIST
Your Sonance Quintette in-ceiling speakers include the following:
• (2) Sonance Quintette speakers
• (2) Paintable grilles
• (2) Plastic paint plugs to protect speakers during painting
• (1) Mounting cutout template (in packaging)
OPTIONAL ACCESSORIES
Quintette FlexBracket (part# 91966) — Plastic template to reserve a
mounting hole for the speaker in new construction. Designed to be
used with the RotoLock® mounting system.
Quintette Coverplate (part# 91458) — Covers the hole made by the
FlexBracket during construction until the speaker is installed.
SPEAKER PLACEMENT
The locations of the speakers should be determined by considering your
primary listening location, the primary use for the speakers (distributed
audio, 2-channel stereo or home theater) and aesthetic values. For
optimum results contact your Authorized Sonance Dealer for advice.
Distributed Audio Placement (Mono Signal)
Sonance Quintette in-ceiling speakers have very smooth and predictable
off-axis response, increasing placement options while providing
excellent coverage in distributed audio systems. The chart below shows
how far apart the speakers can be placed while still providing good
coverage. The distances are based on ±45° of coverage from the speaker
and on ear heights of 62” for standing listeners and 40” for seated listeners.
Home Theater Placement
Left, Center and Right Speakers
• Place the left, center and right speakers from 1 foot to 2 feet in front of
the video screen, anywhere from 6 feet to 10 feet apart, with the center
channel speaker as close to midway between the left and right speakers as
possible.
• Place the left & right speakers at least 2 to 3 feet away from the side walls.
• The main listening position should be between 4 and 10 feet away from
the speakers.
Left & Right Surround Speakers (5.1-Channel System)
Locate the left and right surround speakers on the ceiling between 2 feet
and 6 feet behind the listening position. The speakers should be between
6 feet and 10 feet apart. Since the surround speakers are usually called-
upon to create diffuse effects like the sound of wind or rain, they can be
located close to walls without adversely affecting sound quality.
Use Illustration 1 as a guide for home theater speaker placement.
2-Channel Placement
Follow the directions for Home Theater Placement for the left and right
speakers.
WIRE GAUGE
Extra resistance in the speaker wire can make a speaker sound less
dynamic and reduce definition of the bass frequencies. In extreme cases,
it can even attenuate high frequencies. Also, amplifier power is wasted in
wire with extra resistance, reducing your system’s maximum output level.
To prevent degrading sound quality, the total wire resistance should be
less than 10% of the speaker’s impedance. This means that for an 8-ohm
speaker, the total resistance of the wire should be less than 0.8 ohms.
Refer to the following table when selecting the proper wire gauge for
your system:
