The terminals themselves are designed to allow the use of very heavy speaker wire or connectors. Be sure to tighten them securely, but don’t over-tighten them. WARNING: To prevent risk of electrical shock or damage to your equipment, always switch off the amplifier or receiver when making any system connections. You can connect your speakers by using a variety of audio connectors such as banana plugs, pin connectors, spade lugs, etc., or you can: 1. Remove .” (13mm) of insulation from each wire end. 2. Twist the stranded wire together, keeping the two ends separate. 3. Place the appropriate wire through the postholes in the connectors. These holes are revealed when you loosen the connector’s capscrew. 4. Screw down the capscrew tightly, but be careful not to over tighten it. 5. Check the tightness of the capscrews 24 hours after hookup and occasionally after that, as they can loosen over time. We recommend that you check your local electrical codes to make sure that you are not using improper connectors. It’s important to observe polarity while making speaker connections: red (+) terminals on the amplifier to red (+) on the speaker, black (–) on the amplifier to black (–) on the speaker. Look carefully at the wires you are using and note that one of the conductors of each pair will typically be identified by color, printing on the outer jacket, ridgesonthe outerjacket,ora threadintertwinedwith the wirestrands.By convention, the marked wire is connected to the red (+) terminal.Whether you are connecting a complete system, or adding a single speaker component to your present system, the wiring should look like the system wiring diagrams on the opposite page WARNING: Before turning on the amplifier, be certain that no stray wire strands are touching across any terminals as this might damage your amplifier. Finally, check the polarity of your front speakers by listening to some stereo music with good bass content. If the sound seems “hollow”, unusually spread out, or seem to have weak bass, recheck your connections for proper polarity and correct any out of phase connections, if necessary. System Wiring Instruction Manual System Wiring Be sure to connect red (+) on the speaker to red (+) on the amplifier and black (–) on the speaker to black (–) on the amplifier. LEFTRIGHTSURROUND SURROUND LEFT CENTER RIGHT System Setup System Setup Bass Management Some older surround sound decoders and receivers offer a choice of “Normal” or “Wide-band” modes for the center channel speaker. The Model 1400 C and 2400 C are designed to be used in the Normal mode.Additionally, digital processing multi-channel systems provide a Bass Management menu, which typically requires you to select between “Small” or “Large” speakers during system set-up. Since these systems have been designed to work with a dedicated subwoofer, please set all the speakers in System 1400 or 2400 to Small. If your receiver or processor has selectable subwoofer crossover frequencies, we suggest using 80-100Hz for the 2400 and 100-120Hz for the 1400. Figure 4 Operation of the Rear Panel Controls on the 1400 C and 2400 C High Frequency Energy This control changes the tilt or roll-off slope of the tweeter. It has been designed to help compensate for different room acoustics. The Average position is intended for rooms with a reasonable combination of reflective (hard) and absorptive (soft) surfaces. The Reverberant position is designed for rooms with an abundance of reflective surfaces like hardwood or tile floors, glass walls, etc. It decreases the high frequency output of the speaker to reduce excess HF energy that builds up in live rooms. The Damped position brings the tweeter’s output slightly above flat response to compensate for overly absorbentroomswithlotsof softsurfaces.Speakersinoverlydampedroomscan sound dead and lifeless unless compensated. System 1400 and 2400 High Performance Loudspeakers Boundary Compensation Use this switch to adjust the lower frequency output of the speaker to compensate for the typical sound colorations caused by placing the speaker close to a TV screen or building it into a wall unit or cabinet. To set these controls, sit in the prime listening position and have someone switchbetween thecompensationchoices,usingwell recorded dialogue or musical instrument recordings. Choose whichever switch position sounds most natural and real to you. NOTE: Although these controls have been designed to compensate for various acoustic room anomalies, we recommend that you try them to hear the difference that they make in the sound of the system. For any number of reasons, you may decide that you prefer them set in a particular manner that sounds best to you. Experiment. It will be worth it. Dipole/Bipole Operation of the 1400 SR-z and 2400 SR Speakers In Dipole mode the 1400 SR-z and 2400 SR’s produce ambience with minimal localization (best for most movies and videosoundtracks),andmore localizable sound in the Bipole mode (preferred for some mu...
