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 4400 C is 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 4400 to Small. HF ENERGY REVERBERANTBOUNDARY COMPENSATION ONDAMPEDROOMAVERAGENORMAL4400 LR Front Channel Left or Right Speaker SERIAL POWER: 10-150W 8 OHMS NOMINAL INPUT INPUT Figure 4 Operation of the Rear Panel Controls on the LCR Speakers High Frequency Energy This control changes the tilt HF ENERGY or roll-off slope of the tweeter. It has been designed REVERBERANT to help compensate for different room acoustics.The DAMPED ROOM THX/ Average position is intended for rooms with AVERAGE 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 absorbent rooms with lots of soft surfaces. Speakers in overly damped rooms can sound dead and lifeless unless compensated. System 4400 High Performance Loudspeakers BOUNDARY COMPENSATION ONNORMAL 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 switch between the compensation choices, using well 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 inconsistent with your room’s acoustics,but which sounds best to you. Experiment. It will be worth it. Dipole/Bipole Operation of the SR Speakers In Dipole mode the 4400 SR’s produce ambience with minimal localization (best for most movies and video soundtracks), and more localizable sound in the Bipole mode (preferred for some music recordings). Switching between Dipole and Bipole mode is easily accomplished using a toggle switch conveniently located under one of the speaker’s grilles. Please note that the vast majority of the time in movies and TV broadcasts the surround speakers are called upon to reproduce the environmental sounds that are used as cues to help get you immersed in the scene on the screen. DIPOLEBIPOLE Once the surround speakers are properly positioned in the listening area, we recommend that you begin with the dipole mode, as this usually delivers the most involving and believable surround performance in most situations. However, as noted above, feel free to experiment with both switch positions. When using as front "height" speakers, we recommend starting in the Bipole mode. Mounting Instruction Manual Setting Levels When setting up a complete home theater we strongly recommend that you use a Sound Pressure Level (SPL) meter.As of this writing Radio Shack® has one that’s affordably priced (approximately $40) that can be used effectively. To use this meter, turn on your system, put the processor/receiver in Test Mode and set its main volume control to 0dB (or a reasonably loud level). Sitintheprimelisteningposition,settheSPLmeter tothe70dBscale,slow response, and C weighting. Hold the meter with the microphone pointed up, towards the ceiling and in front of you. Cycle the test tone from speaker to speaker, setting each to the same level (usually75dB) using the individual level settings available in the processor/receiver (please see the instructions for your processor/receiver if you are unsure of how to access the test signal or level controls). IMPORTANT NOTE: The power recommendation for these speaker systems assumes tha...
