Bi-Wiring & Bi-Amping 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. POWER AMPLIFIER FRONT R L Bi-wiring, or using separate speaker wire connections for high and low frequency sections. Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers by running separate speaker wires to further enhance its low and high frequencies. After removing the jumpers, connect one set of speaker wires to the upper binding post terminals on each speaker and one set of (usually heavier gauge) wires to the lower binding post terminals. Connect the other ends of both wire sets to the corresponding amplifier outputs. LOW FREQUENCY HIGH FREQUENCY AMPLIFIER AMPLIFIER RL RL Bi-amping, or using separate amplifiers for the low and high frequency sections of your speakers. Bi-amping allows you to use separate amplifiers for the high and low frequency sections of your loudspeaker for greater dynamic range and lower distortion. After removing the jumpers, connect the speaker wires from the high frequency amplifier outputs to the upper set of terminal posts on each speaker. Follow the same procedure for connecting the low frequency amplifier outputs to the lower set of terminals. Remember to maintain correct wiring polarity (+ to +, - to -) in all connections. Ensure the sensitivity of each amplifier is the same to avoid poor sound quality. EN-11
