•You can also use banana plugs for this connection. To do so, you must first remove the caps from the terminal posts.

3Connect the other ends of the cables to the amp's speaker output terminals (for more details, refer to your amp owner's manual).

•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.

•If the cables' wires happen to be pushed out of the terminals, allowing the wires to come into contact with each other, it places an excessive additional load on the amp. This may cause the amp to stop functioning, and may even damage the amp.

•When using a set of speakers connected to an amplifier, you won't be able to obtain the normal stereo effect if the polarity (￿,￿) of one of the speakers (left or right) is reversed.

Bi-wiring 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.

Caution: when bi-wiring

Note that in this setup, connecting the cables with the polarity reversed may seriously degrade the tone; refer to the section "Connecting the cables" again and confirm that the cables are connected properly.

3Connect the matched pairs to the same speaker terminals on your amp (taking care not to get the polarity reversed).

Make sure to use the same type of cable for the low-fre- quency and the same type for the high-frequency connec- tions.

When bi-amping

Bi-amping is an even more powerful way of connecting your speakers. Just as with bi-wiring, the input terminal short bars are removed, but here the low-frequency terminals are connected to a separate, dedicated low-frequency amp, and the high-frequency terminals are connected to a dedicated high-frequency amp.

1Loosen the cap knobs on the left input terminals and remove the two short bars.

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.
