• After connecting the wires, pull lightly on them to

make sure that the ends of the wires are securely

connected to the terminals. Poor connections can

create noise and interruptions in the sound.

• If the wires are pulled out of the terminal posts and

the conductors come into contact with each other or

surrounding devices, an excessive additional load

may be placed on the amplifier. This may cause the

amplifier to stop functioning, and may even cause it

damage.

• Be careful to observe the correct polarity of the

connections between the cables and the speaker. If

the polarity (+, –) of one of the speakers (left or right)

is reversed the stereo image will be severely

degraded.

7 Where available, use the fixing bracket located on

the back of the speaker system and attach a reinforced

wire, such as stainless steel wire rope, to the studs or

beams of the walls/ceiling.

• It is strongly recommended that you take double safe

precautions to prevent the speaker from falling by

accident.

• Put the reinforced wire through the fixing bracket and

attach to the studs or beams. Make sure the stud/

beam that you are attaching it to is strong enough to

support the weight of the speaker system.

8 Place sound-absorbing material (such as fiberglass)

around the speakers as necessary to improve sound

quality.

Use only sound-absorbing materials that comply with

regional safety regulations.

9 Place the speaker into the hole you have cut.

Make sure the rotating clamps are turned inward.

• A Phillips screwdriver is required for loosening them.

• When using electric screwdrivers, first find out the

minimum torque required for the installation of the

speaker system. Begin by setting the electric

screwdriver to its minimum torque and gradually

raise the torque until the screw starts to rotate. Check

what torque setting you are on at this point (this will

be the minimum torque required for the setup). After

confirming the torque, return the rotating clamps

toward the inside by reversing the direction of

rotation of the screws. When doing this, take care

that the screws do not come all the way out.

10 Attach the speaker frame to the wall/ceiling, and

tighten the screws lightly (temporary attachment).

At this point the rotating clamp will rotate so that the

rotating clamp and frame are clamped on to the wall/

ceiling.

Gently try pulling the speaker forward and check that all

of the rotating clamps have rotated outwards and are

lightly clamping to the wall/ceiling.

11 Tighten the screws firmly using no more than the

maximum torque specified.

Allowable maximum torque: 1.0 N⋅m

• Screwing them in too tightly could break the rotating

clamps, twist the frames, damage the walls/ceilings

and make it difficult to attach the grille.

12 Make sure that the screws are not crooked and that

there is no gap between the wall/ceiling and frame.

CAUTION

These speaker terminals carry HAZARDOUS LIVE

voltage. To prevent the risk of electric shock when

connecting or disconnecting the speaker cables,

disconnect the power cord before touching any

uninsulated parts.
