Attaching and detaching the speaker grilles
This speaker system uses detachable grilles. Use the
following method to attach or detach the grilles.
1. While holding the bottom edge of the speaker grille with
your both hands, pull it gently toward you to remove the
bottom of the grille.
2. In the same way, gently pull the upper edge of the speaker
grille toward you to remove it from the main unit.
3. To replace the grill, push the projections at the corners into
the grille plug holes on the speaker cabinet.
Use with a TV set
In general, Braun tubes used for color television sets, etc. are
extremely sensitive and can be affected even by the
magnetism of the earth. If a speaker system is used near
them, therefore, discoloration or distortion of pictures will
occur. To allow use with color television sets, etc., this speaker
system is provided with magnetic shielding.
Even so, discoloration may still result, depending on the
installation environment. If discoloration occurs, turn off the
power of the television set, wait for 15 to 30 minutes and then
turn it on again. This activates the self-demagnetizing function
of the television set, improving the display condition. If
discoloration persists even after performing this remedy, move
the speaker apart from the television set. Discoloration may
also be caused when a magnet or other magnetizing object
exists near the television because of the combined effect.
Speaker care
Your Onkyo speakers are finished with a high quality covering
that serves to protect the wood speaker cabinet.
Wipe the cabinet periodically with a dry, silicon-embedded or
plain soft cloth.
The covering may be cleaned with a soft cloth moistened with
water and a mild soap. Avoid the use of furniture polishes or
harsh cleansers. Use a soft brush or hand vacuum cleaner to
remove dust and lint from the grille material.
Natural wood finished cabinets
The cabinets are finished with a natural wood surface. They
have a unique wood grain pattern. Your cabinets have their
own raw beauty and uniqueness which is unlocked from the
tree; this is depicted by the cross-grain patterns with dark and
light coloring. You can enjoy Onkyo’s craftsmanship not only
when designing for the best sound quality, but to assimilate
natural blessings for the visual senses. The paint and finishing
work of the cabinets are conducted under the strictest quality
control standards.
Placement
Using as a surround speaker
Enhance the sensation of being at a live performance by
giving three-dimensional sound movement to the sound
effects. Place the surround speakers at the side of the listener
or at a position diagonally from the listener. Ideally, speakers
should be placed symmetrically.
Place these speakers so that their height is 1 meter higher
than that of the listener’s ears.
The speaker cabinet is made of wood and sensitive to extreme
temperatures and humidity. Avoid placing the speaker system
in locations subjected to direct sunlight or in humid places
such as near an air conditioner, bathroom, or kitchen.
Installing on the wall
If the speakers are to be wall-mounted, make sure that the
walls are strong enough to support the speaker’s weight. The
weight that mounting screws can support varies greatly
depending on the wall material and the position of the
reinforcing ribs embedded in the wall. Use the thickest and
longest possible mounting screws with mounting screw head
diameters less than 10 mm and shank diameters less than 4
mm (consult with your interior designer or contractor).
Attach the supplied cushioning pads as shown to wall-mount
the speaker securely.
Installation using commercially-available stands
and fixtures
The surround speaker bottom and rear are equipped with
screw holes so that you can attach commercially-available
stands or mounting fixtures for a variety of mounting options.
(Two M5 screw holes, 60 mm pitch on the bottom and the
rear.)
Note:
When attaching an accessory item to a speaker, be careful of
the length of the screws used. Use only screws that provide
the required strength with a screw length between 3 and 11
mm.
