This section describes a suitable installation location to install the unit using a metal wall bracket, a rack or a stand.
This unit creates surround sound by reflecting projected
sound beams off the walls of your listening room. The
surround sound effects produced by this unit may not be
sufficient when the unit is installed in the following
locations.
• Rooms with surfaces inadequate for reflecting sound
beams
• Rooms with acoustically absorbent surfaces
• Rooms with measurements outside the following range
W (3 to 7 m (10 to 23 ft)) x H (2 to 3.5 m (7 to 11.5 ft))
x D (3 to 7 m (10 to 23 ft))
• Rooms with less than 1.8 m (6 ft) from the listening
position to the speaker positions
• Rooms where objects such as furniture are likely to
obstruct the path of sound beams
• Rooms where the listening position is close to the walls
• Rooms where the listening position is not in front of
this unit
Make sure you leave an adequate amount of ventilation
space so that heat can escape. Make at least 5 cm (2 in) of

directly on the floor of your listening room. Please install this
unit using a metal wall bracket, rack or stand.
• This unit weighs 9.0 kg (19 lbs 13 oz). Be sure to install this
unit where it will not fall subject to vibrations, such as from an
earthquake, and where it is out of the reach of children.

unit directly above your TV.
• This unit is shielded against magnetic rays. However, if the
picture on your TV screen becomes blurred or distorted, we
recommend moving the speakers away from your TV.

furniture obstructing the path of sound beams. Otherwise,
the desired surround sound effects may not be achieved.
