Classic Absolute Center Center Channel Loudspeaker Setup Guide rev 806 NHT's Classic Series represents our best efforts to date in passive loudspeaker design. Classic starts with the design fundamentals that have made NHT's reputation for accuracy and high performance, and adds new driver and cabinet technologies which reduce distortion and improve dispersion. The benefit to you is a more articulate, more musical listening experience. Placement NHT's Classic center channel designs are meant to be placed horizontally. Ideally the center channel should be placed immediately above or below the television, in as close proximity as possible (Fig. 2). All Classic Series models share a similar "voice" or tonality so that you are assured a matched system no matter which models you decide to add as you build your system. The following Setup Guide will help you unpack, connect and place your new Classic loudspeakers in your listening room. If you are interested in specifications or the technology used in the design, please visit our website at www.nhthifi.com and look up information on your specific model. If at any time during or after setup you require assistance, feel free to call our Customer Hotline at 1-800-NHT-9993 (800-648-9993). The Absolute Center is designed as the matching center channel loudspeaker for the NHT Absolute Zero. The compact size is perfect for small to medium size rooms. Fig. 2 The three front speakers in a home theater system sound best when placed at the same distance and the same height in relation to each other. In addition, try if possible to have the tweeter height close to ear level when sitting. In situations where the top face of your television may be higher than ear level, you can use the supplied "3rd foot" (Fig. 3) to aim the speaker at your listening position. Fig. 3 To use the "3rd foot", simply adjust the center channel to the angle you desire and tighten the finger screws. Try to position the front of the center channel to be even with the front of the televison or shelf on which it is placed. This eliminates undesirable reflections and improves intelligibility of the speaker. This can be difficult to achieve with some standard televisions that have curved or angled tops. We have provided a rubber pad on the lower end of the foot which will provide a stable base for the back of the center channel in such situations. Be sure you review safety and stability of the center channel before considering setup complete. Connections Before connecting your Classic center channel to your receiver/amplifier, turn off the AC power to avoid potential damage to your components. Take a look at the terminals on the back of your speakers. They can accept raw wire, banana plugs or spade lugs. Note that these terminals should be tightened only by hand, as excess force can break them. We recommend your speaker wire be at least 16 gauge. Your NHT dealer can recommend the correct wire. Use the same length of wire for each channel. The best tool you have is your ears. If you hear unusual distortion or breakup, decrease the volume immediately. If you are unsure, place your hand close the woofer. If you feel heat radiating from the driver, you are playing the system beyond its limits. Maintenance Your NHT speakers will require little if any maintenance under normal use. Try to avoid exposing them to direct, sustained sunlight, high temperatures or moisture. Cabinets can best be dusted using a clean, soft chamois cloth. The finish on your speakers is durable but dry rough cloth can leave fine scratches over time. Try to avoid using liquid cleaners and household furniture polish, particularly around the speaker components. To clean grilles, remove them from the speaker and use a soft brush or a vacuum on its lowest setting. Do not attempt to clean the speaker components. Satisfaction We hope you enjoy the sound of your NHT Classic speakers as much as we do. Your warranty is printed on the back of this Setup Guide. Once again, if you have any questions or problems, please call us at our Consumer Hotline. 1-800-NHT-9993 Prepare the wires by stripping ¼" - 3/8" of insulation from the ends and tightly twist the exposed strands. Finally, connect your speakers to your amplifier or receiver, making sure that the speakers are "in phase,” that is, the same half of the wire pair connected to the Positive terminal (+, usually red) on both the amplifier and the speaker. The other half of the same wire connected to the Negative (-, usually black) terminals on both amplifier and speaker. Most speaker wire has one half of the pair marked with either lettering, ridges, the "+" sign or color to help you make the proper connections. Before powering up your receiver/amplifier, make sure there are no stray strands from one terminal touching the other terminals. Also, try to keep speaker wires from laying across AC power cords. Operation All NHT Classic speakers are compatible with most amplifier power ranges and are designed to handle a wide range of listening levels. Every speaker, however, has limits and it is important to listen for them. Speaker damage most often occurs from sustained high volume levels in some or all frequencies. Try to avoid excessive bass or treble settings or equalizer boosts. Per the EC directive of WEEE (Waste Electrical and Electronic Equipment) this product may not be disposed of as waste.
