ONKYO HT-S3300 Manuel D’Utilisation

En

The speakers can easily be wall mounted by using the key-
hole slots. To prevent the speaker from vibrating against 
the wall, attach two of the supplied thick rubber stoppers 
to the rear of each speaker.

To mount the front or surround speakers vertically, use the 
keyhole slot shown to hang each speaker on a screw that’s 
securely screwed into the wall.

To mount the center speaker horizontally, use the two key-
hole slots shown to hang each speaker on two screws that 
are securely screwed into the wall.

• A mounting screw’s ability to support a speaker depends 

on how well it’s anchored to the wall. If you have hollow 
walls, screw each mounting screw into a stud. If there are 
no studs, or the walls are solid, use suitable wall anchors.

• Use screws with a head diameter of 5/16" (9 mm) or less 

and a shank diameter of 1/8" (4 mm) or less. With hol-
low walls, use a cable/pipe detector to check for any 
power cables or water pipes before making any holes.

• Leave a gap of between 3/16" 

(5 mm) and 7/16" (10 mm) 
between the wall and the base 
of the screw head, as shown. 
(We recommend that you con-
sult a home installation profes-
sional.)

We recommend using the provided rubber stoppers to 
achieve the best possible sound from your speakers. The 
rubber stoppers prevent the speakers from moving, provid-
ing a more stable platform. Use thick stoppers for the cen-
ter speaker, and thin stoppers for the other speakers.

If the subwoofer is placed on a hard floor (wood, vinyl, 
tile, etc.) and playback is very loud, the subwoofer’s feet
may damage the flooring. To prevent this, place the sup-
plied pads underneath the subwoofer’s feet. The pads also 
provide a stable base for the subwoofer.
