CAUTION

• Magnets are used for holding the grille in place. Do not place

the grilles near devices that may be susceptible to magnetic

influence (CRT televisions, etc.).

Bi-Wire connections

Bi-wiring requires two cables for each speaker, one for high

frequencies and one for low frequencies. Using separate cables

for the high end and low end improves the sound.

• In this state, the low-frequency speakers and the higher-

frequency speakers are completely independent. Store the

short bars in a safe place for later use.

• The lower terminals are for the bass, and the upper terminals

are for midrange and treble sounds.

• Connecting the cables with reversed polarity may degrade the

tone seriously. Confirm that the cables are connected

properly.

3 Connect the other ends of the cables to the amp's

speaker output terminals (for more details, refer to your amp

instruction manual).

• Grasp the cap knobs on the lower input terminals and rotate

them to the left (counter-clockwise), insert the speaker cable

wires into the holes in the terminal posts, then tighten the

knobs to secure the short bar as well as the wires.

• You can also connect the speaker’s terminals with a banana

plug. When using a banana plug, be sure to remove the cap at

the tip of the input terminal.

• After connecting the plugs, pull lightly on the cables to make

sure that the ends of the cables are securely connected to the

terminals. Poor connections can create noise and

interruptions in the sound.
