Connections
• Before connection, turn off the amplifier to avoid
damaging the speaker system.
• This speaker system is driven best by an amplifier or
receiver rated as per the wattage indicated in the
specification section.
A low-powered amplifier could result in signal
clipping which could result in tweeter burn-out.
Therefore, it is recommended to use an amplifier or
receiver with sufficient power rating.
Note
Avoid driving the speaker system continuously with a
wattage exceeding the maximum input power of each
speaker.
Precautions
• Do not attempt to open the enclosure or remove
speaker units. There are no user-serviceable parts
inside.
• Keep recorded tapes, watches, and personal credit
cards using magnetic coding away from the speaker
system.
• Periodically wipe the cabinet with a soft cloth.
Do not use any type of scouring powder, abrasive pad
or solvent.
• Be sure to install the grill net in the correct direction.
Speaker Placement
Please note that room acoustics can often produce large
difference in the sound for small changes in speaker
placement.
• Set up your speaker system on a hard, flat floor.
• Place the speaker system against a hard wall with its
back about 10 cm (4 inches) away from a wall. The
proportion of bass increases as you move a speaker
close to intersecting room surfaces (wall and wall,
etc.).
• Place the right and left speakers in a similar acoustic
environment.
• It is recommended that the speaker/listener
relationship be an equilateral triangle.
