Positioning the system

The following illustration shows an example of
positioning the system. Note that the illustrations
in these instructions dier from the actual unit for
explanation purposes.

For the best possible surround sound, all the
speakers other than the subwoofer should be
placed at the same distance from the listening

position ( ).

Front left speaker (L)/ Front right speaker (R):

Place the front speakers to the sides of the
monitor or screen and as ush with the screen
surface as possible.

Center speaker: Place the center speaker above

or below the monitor or screen.

Surround left speaker (L)/ Surround right

speaker (R):
Place these speakers behind your listening
position, facing slightly inwards.

Subwoofer: The position of the subwoofer is

not so critical, because low bass sounds are not
highly directional. But it is better to place the
subwoofer near the front speakers. Turn it slightly
toward the center of the room to reduce the wall
reections.

Note

,

yIf there is a strong electromagnetic wave

product nearby, interference may occur.
Put the unit (Wireless Receiver and main
unit) away from there.

yIf there is no audio signal for longer than

10 minutes, the Wireless Receiver will
automatically switch to standby mode. In
power saving mode, both LEDs will turn
red. LEDs will turn blue or yellow when
there is any audio signal back.

yIf you operate main unit then wireless

speakers (rear speakers) sound within a few
seconds in standby mode.

ySet the distance between this unit and

Wireless Receiver within 10 m (32 ft.).

yOptimum performance can be

implemented only when the Wireless TX
and the Wireless Receiver within distance
of 2 m (6 ft.) to 10 m (32 ft.) is used since
communication failure may occur if longer
distance is used.

yBe sure to match the speaker cable to the

appropriate terminal on the components:
+ to + and – to –. If the cables are reversed,
the sound will be distorted and will lack
bass.

yIt takes a few seconds (and may take

longer) for the Wireless TX and Wireless
Receiver to communicate with each other.

yUse the rear speaker at least 30 cm (11 inch)

away from either TV screen or PC monitor.
