PRECAUTIONS

Read these precautions carefully before using your speaker.

•

Any time you note distortion, reduce the volume control on

your amplifier to a lower setting. Never allow your amplifier

to be driven into “clipping”. Otherwise the speaker may be

damaged.

•

When using an amplifier with a rated output power higher

than the nominal input power of the speaker, care should

be taken never to exceed the speaker’s maximum input.

•

Do not attempt to clean the speaker with chemical

solvents as this might damage the finish. To clean, wipe

with a dry, soft cloth.

•

To prevent the enclosure from warping or discoloring, do

not place the speaker where it will be exposed to direct

sunlight or excessive humidity.

•

Do not place the speaker where it is liable to be knocked

over or struck by falling objects. Stable placement will also

ensure better sound performance.

•

Placing the speaker on the same shelf or rack as the

turntable can result in feedback.

•

This speaker system is designed for home use only. Never

use this speaker system inside a car.

•

Secure placement or installation is the owner’s

responsibility.

YAMAHA shall not be liable for any accident caused

by improper placement or installation of the speaker.

ATTACHING STAND

Attach the included stands to the

speakers using the two included

screws. Place the speakers next

to a personal computer on a

desktop to achieve the optimum

listening position. Be sure to

attach the stands to the speakers

correctly as shown in the figure.

If you attach them in the opposite

direction or otherwise incorrectly,

the speakers may fall and be

damaged or cause injury.

■

Non skid pad

To prevent the speakers from sliding around, attach the

supplied pads as shown in the illustration.

You can also use the screw holes on the rear of the speaker

for installing the speakers.

60 mm

A screw with a diameter of 4 mm and a

pitch of 0.7 mm can be used.

(Depth of hole: 8 mm)

CONNECTION TO YOUR AMPLIFIER

BEFORE MAKING CONNECTIONS, MAKE SURE THAT

THE AMPLIFIER IS SWITCHED OFF.

■

CONNECTIONS

•

Connect the push-type input terminals at the rear of the

speakers to the speaker output terminals of your amplifier

with the provided speaker cord.

•

One side of the speaker cord is marked by a red line.

Connect the (+) terminals on both the amplifier and the

speakers using this red-marked side. Connect the (–)

terminals on both components using the black-side of the

cord.

•

Connect one speaker to the left (marked L) terminals of

your amplifier, and another speaker to the right (marked R)

terminals, making sure not to reverse the polarity (+, –). If

one speaker is connected with reversed polarity, the sound

will be unnatural and lack bass.

Procedures:

1

Press the tab on the terminal down, as shown in the

figure.

2

Insert the bare speaker wire end properly into the terminal

hole. [Remove approx. 5 mm (1/4") insulation from the

speaker cord.]

3

Remove your finger from the tab to allow it to lock snugly

on the cord’s wire end.

4

Test the security of the connection by tugging lightly on the

cord at the terminal.
