INTRODUCTION

OSS165

Your speaker is an example of superior design and craftsmanship.
These suggestions will help you care for them so you can enjoy
them for years.

Keep the speaker dry. If it gets wet, dry immediately. Liquids can
contain minerals that can corrode electronic components.

Keep the speaker away from dust or dirt, which can cause
premature wear of parts.

Wipe the speaker frame occasionally with a damp cloth to keep it
looking new. Do not use harsh chemicals, cleaning solvents or
strong detergents.

CARE AND MAINTENANCE

4

It is advisable to plan all aspects of installation in advance of work
beginning, preferably with the house/flat building schematics if
available. Great care should be taken to ensure that all building
regulations are followed. When deciding upon a ceiling placement,
care should be taken to avoid joists, load bearing beams etc.

When placing the OSS165 speaker, thought should be given to
positions which give the best desired sound coverage throughout
the room, while not interfering with existing or planned light fittings
or joists. Also, locate loudspeaker taking into account location of
furnishings for optimal stereo reproduction.

Before cutting ceiling loudspeaker holes it is suggested that the
area is tested for clearance by making an L-shaped probe from
strong wire (eg a coat hanger), drilling a small hole in the target
area, inserting the probe and slowly turning. Any obstructions will
be immediately obvious, and the target area can be moved to a
more suitable position.

When mounting speaker flush to a ceiling or wall, ensure that
enough depth/clearance is available in the respective cavity. A
clearance of at least 80mm is necessary when mounting an
OSSI65.

Remove the round cardboard pad from inside the supplied
template (see below). Use the template to mark the position for the
mounting hole at the selected location. Cut the mounting hole with
a drywall or keyhole saw.

1. Remove the grille by inserting a small hook or similar small
implement into one of the grille openings, then pulling on the
grille.

2. Fit the clear plastic painting mask provided when painting the
speaker surround to avoid paint getting on the speaker cone.

3. Spray-painting the grille will prevent blocking the grille holes with
paint.

4. After the paint dries, remove the paint mask, replace the grille
and apply grille badge as required.

Do not compromise the performance of your system by using
inferior quality speaker cables. We recommend that high quality
cables of 16 gauge or higher be used. Your professional dealer will
give you good advice. Always unplug all A.C. powered components
before making any loudspeaker or component connections. This
will avoid the risk of electric shock or damage to your equipment.

Follow these steps to connect the speaker to your amplification
system:

1. Route the speaker cable from your amplification system to the
speaker. Avoid routing the speaker cable near electrical wires
and do not nail or staple the cable.

2. Separate about 100mm of speaker cable at each end.

3. Using a wire stripper, remove about 10mm of insulation from
both ends of each conductor, and then twist the strands of each
conductor (Fig. 1).

4. Observing polarity is of the utmost importance while connecting
your speaker. Ensure that the red (+) terminal on your
amplification system is connected to the red (+) terminal on the
speaker, and black (-) terminal on your amplification system to
black (-) terminal on your speaker (Fig. 2). Press the spring­loaded red or black tab back to reveal the connecting hole. Insert
the stripped end of the speaker wire, then release the tab.
Repeat procedure for the second set of terminals.

5. If your speaker is wired incorrectly they will be out of phase and
sound hollow and indistinct, with a weak bass. Re-check your
connections for correct polarity and reverse the connections if
necessary.

1. Before mounting, ensure that the four fixing screws are
slackened off so that the red mounting dog-legs can move freely.

2. Move each red dog-leg foot to the LEFT into it’s holding slot, and
then insert the speaker into the mounting hole.

3. Using a cross-head screwdriver, slowly turn each fixing screw
clockwise. This will move the mounting dog-legs out of their
slots.

4. Tighten each fixing screw until the mounting dog-legs grip the
ceiling.
