POSITIONING SETUP
Positioning of the transmitter Adjusting the relative sound level
Position the unit in a way that you are able to "see" the
active surround speaker from the position of the unit.
To avoid sound distortions caused by magnetic fields do not
place the transmitter on your TV set.
Positioning of the speakers
Important!
To avoid overheating do not cover any vents and leave
a minimum distance of 5 centimeters (? inches) for
ventilation.
General hints for positioning
Avoid positioning the speakers in a corner or on the floor, as
this will boost the bass tones too much. Placing the speakers
behind curtains, furniture etc. will reduce the treble response,
thus reducing the stereo effect considerably. The listener
should always be able to "see" the speakers.
Each room has different acoustic characteristics and the
positioning possibilities are often limited. You can find the
best position for your speakers by following the picture
above. The speakers should always be arranged as
symmetrically as possible in the room.
Positioning the center speaker
The center speaker should be placed in the center between
both front speakers, e. g. underneath or on top of the TV. The
best height for the center speaker is at the height of the
listener's ears (while seated).
Positioning the surround speakers
The surround speakers should face each other and be in line
with, or at most 1.5m (4ft 6ins) behind the listener.
After installing your speakers, you will have to find a good
sound balance between the surround, center and front speakers.
In the instruction booklet of your appliance you will find a
section describing how to adjust the sound of the different
speakers. Follow those instructions to get the most out of
your new speakers.
Setting the input sensitivity A-B-C
Depending on which sound source you use, the signals
delivered have different strengths.
If the red light on the front of the transmitter unit starts to
blink, the incoming signal is too strong. This will cause
distortions. Set the A-B-C switch to adjust the input sensitivity
to a lower level. If the red light on the front of the transmitter
unit goes off during play, the incoming signal is not strong
enough. Set the A-B-C switch to adjust the input sensitivity to
a higher level.
Setting the transmitting channel
In case of signal interference from the transmitter it is
possible to change to another transmitting channel.
1 Switch off both active surround speakers.
2 Set the CHANNEL slide at the back of the transmitter to
another number.
3 Set the CHANNEL slide at the back of both active surround
speakers to the same number as on the transmitter.
4 Switch on both active surround speakers.
Note: -Always be sure that the transmitter and the active
surround speakers are switched to the same transmitting
channel, otherwise no sound or only a distorted sound
will be heard on the surround speakers.
Switching On-Standhy-Off
The transmitter is equipped with a sensitive input. If there is
no signal on the SUB and SURR input the transmitter and the
surround speakers will switch to standby after approximately
100 seconds.
The green light on the front of the active surround speakers
shows that the speakesr are on. If the red light is on, the
speakers has switched to standby. To switch the active
speakers off, use the POWER switch.
If the red light on the front of the transmitter is off, it has
switched to standby. To switch the transmitter off, unplug the
AC/DC adapter from the power source.
