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

Positioning the speaker

The optional speaker stand

1Secure the pedestal (A) to the speaker with the supplied screws (E) and washers (D). (A)

2Attach the spikes (B) and the jam nuts (C) to the bottom of the pedestal (A). Fully insert the front spikes (B) into the pedestal (A). (A)

3Lay the spike pads (F) (hollow side up) on the installation site and install the pedestal and speaker. Using the supplied wrench (G), adjust the back spikes (B) until the speaker is level. (B)

•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

B

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.
