Signature Series Bi-Wiring (S60, S55 and S50 Towers) Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. After removing the jumpers, run separate speaker wires to the low and high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers, the lower set of binding posts are for the low frequency drivers). Connect one set of speaker wires to the upper terminals on each speaker and one set of wires to the lower terminals. Connect the other ends of both wire sets to the same amplifier outputs. See Amplifer/AVR's user manual for configuration instructions. Amplifier - L+ - R+ -+ - L+ Input -+ - R+ Input Bi-Amping (S60, S55, S50 Towers) 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. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance. 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. See Amplifer/AVR's user manual for configuration instructions.

Note: For older TV's, the S35 and S30 are NOT magnetically shielded. Also compatible as a left, center or right speaker (L/C/R), the S35 center channel speaker includes built in keyhole slots for easy wall-mounting (see instructions on wall mount template for more information). Processor Mode Note: Set these speakers (S35, S30, S20, S15, S10) to "small" in your receiver's Bass Management Settings. Set to "large" for tower speakers (S60, S55, S50). The "bass management" or "speaker configuration" menus of most surround receivers offer the choice of "normal" or "wide" modes for smaller speaker operation. In discrete channel digital processors, these modes are referred to as "small" and "large." Normal (small) mode filters bass frequencies from center channel, bookshelf and satellite surround speakers, and sends them instead to the front left and right main speakers or to the subwoofer output (LFE) jack. Wide (large) mode sends an unfiltered, full-range signal to these speakers. Use the Small (normal) mode for optimum center and surround channel performance and reliability. Signature Series Speaker Positioning To maximize the sound quality of your speaker system- whether you've purchased tower speakers, a center channel speaker, bookshelf speakers, or satellite surround speakers -correct placement is everything. Take a look at the following examples and give them a try based on the Signature Series speakers you've purchased. Note: Your Signature Series speakers are compatible with 2.0, 2.1, 3.1, 5.1, 7.1 and 9.1 setups (optional subwoofer shown in graphics). 1. 5
