Processor Mode Configuration for the FXi Series Surround FX Loudspeaker: Set Surrounds to “Small” in your receiver’s Bass Management settings.

CONNECTING YOUR LOUDSPEAKERS [FIGURES 5 & 6]

We recommend 16-gauge or larger speaker wire. Follow the hookup directions included with your receiver. Strip 1/2 inch (12.7mm) of insulation from each of the two conductors of the wire to expose the bare metal and twist each of the individual conductors into single unfrayed strands. Note that one of the terminals on the rear of each speaker is red (+) and the other is black (-). Make certain that you connect the wire from the red (+) terminal of your amplifier or receiver to the red (+) terminal on your speaker and the wire from the black (-) terminal of your amplifier or receiver to the black (-) terminal on your speaker. Most wire has some indicator (such as color-coding, ribbing or writing) on one of the two conductors to help you maintain consistency.

To connect wire to the binding post [figure 7], unscrew the hex nut and insert the bare wire into the hole near the base of the binding post. Do not insert the insulated part of the wire into the hole as this will not give you a good connection. Twist the hex nut back down the binding post until it firmly meets the wire. Do not over tighten.

To use Banana Plugs (US only): Unscrew the binding post lug nuts completely to expose the binding post plugs (plastic plugs inserted into the binding posts). Carefully pry out the binding post plugs to expose banana plug holes. Screw the lug nuts back on the binding posts and insert banana plugs. (This is for US owners only.)

BI-WIRING OR BI-AMPING THE CSi40

If you decide to bi-wire or bi-amp, you must remove the flat metal jumpers between terminal posts. Failure to do this could result in damage to your amplifier and loudspeakers.

Bi-wiring [figure 8] can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low and high frequency drivers from a single amplifier: after removing the jumpers, connect one set of speaker wires to the upper terminals on each speaker and one set of (usually heavier gauge) wires to the lower terminals. Connect the other ends of both wire sets to the corresponding amplifier outputs.
