Yamaha NS-AW150 2-Way Indoor/Outdoor Speakers (Pair, Black)

Yamaha's compact NS-AW150 bookshelf speakers provide an affordable way to enjoy your music or television programming on a deck or under a porch. You can bring them in during the cold months and set them up indoors, too: their high build quality and good sound lend them equally well to two-channel indoor listening. The speakers, which are sold as a pair, each use a 6.5-inch high-compliance, polypropylene, mica-filled woofer and 0.5-inch PEI dome tweeter. The drivers are optimized for high rigidity but low mass, giving them reasonably high sensitivity (80 dB with 2.83V at 1 meter), another way of saying modest amplifiers won't have much trouble driving them. Their acoustic-suspension cabinets are sealed to prevent undue resonance or tubby, tuneless bass, which often results from low-cost ported designs.

How To Choose The Best Stereo Receiver For Your Needs

!9#: How To Choose The Best Stereo Receiver For Your Needs

It used to be a lot simpler to find the best stereo receiver for your needs since most people only used receivers for their home audio system, but today the addition of video devices and the multitude of audio/video sources makes the choice more demanding. So here are a few tips to keep in mind as you shop for a stereo or digital receiver.

First of all make sure that the receiver that you choose to be the brain of your home entertainment center will be able to support all the devices that you intend to use with it. These days video and audio can come from a variety of sources including camcorders, digital video recorders, DVD players, cable or satellite boxes, video game systems, cd players and so on. You will need to have corresponding inputs for however many devices that you intend to use. So plan ahead and make sure the receiver you buy will fit your needs that way. You will have to pay more for a digital receiver that carries a plethora of input connections, but it will be worth it in the long run.

Also be sure that the connections for both audio and video match between your components and the receiver. Most devices can support a standard composite cable connection, but for your best video sources you will probably want some S-video connections that produce a better screen picture with more detail. On the audio side, if you are using surround sound as many people are these days, make sure that the audio connections from your components match the inputs on your receiver. For digital equipment it is usually either an optical or coaxial connection, but whichever it is, be sure that the connections on both ends will match.

Then be sure that the receiver will be sufficient for your room size. Most rooms will take about 50 watts per channel to power the speakers sufficiently, but larger rooms may require 75 watts per channel and very large rooms can use 100 watts per channel to fill the room up with sound.

You also will need to match the receiver to your speakers too as some speakers use different ohm ratings to accomplish their sound purpose. An ohm has to do with how much resistance there is to the current being sent from the receiver. If you match an 8 ohm receiver with a set of 4 ohm speakers you may damage your receiver because of all the overwork that it has to do to keep up with the current demand from the speakers. So just make sure that you match the receiver requirements to the speaker set that you have.

Finally, don't assume that price is the definitive guide for quality. Many reviews of the best stereo receivers have concluded that high quality equipment does not always cost more, so read the reviews, shop around thoroughly and follow the suggestions given above and you can make a good stereo receiver purchase.

Eliminating that Terrible Hum From Your Home Theater Speakers

!9# Eliminating that Terrible Hum From Your Home Theater Speakers

[if ]

[endif]

You've all heard it, that dreaded 60Hz hum through the speakers of a home theater or house audio system. Hopefully you heard it at a friend's house and not your own. It can drive you completely nuts. You may have even tried, unsuccessfully, to fix the little noise problem. That can make you even more crazy. What causes that horrendous noise through your speakers?

More often than not humming through your speakers is caused by a grounding problem. There are three main ground problems that cause problems in an audio / video system. These are ground loops, improper grounding and lack of a ground altogether. The other possible culprits that can cause noise are bad cables, a faulty piece of equipment or electrical noise from a lighting dimmer or electric motor. There are steps you can take to troubleshoot the noise and eliminate it from you theater.

The first step is find out where it is coming from. Disconnect your source and display equipment from your receiver or surround sound processor. If the noise stops, connect them back to the receiver or processor on at a time until the noise returns. When the hum comes back, you found where the noise is entering your system. Note that if you are connecting remote equipment, such as running the signal from your theater room DVD player to the TV in the bedroom, your chances to pick up noise increase dramatically. With such long runs, noise can be induced into the long cable runs from adjacent electrical wiring. It is also easy to create a ground loop, because the equipment is plugged into two different, widely separated outlets, on different electrical circuits.

If the noise is caused by a cable box, the noise is likely caused by the cable TV ground. To test this theory, disconnect the incoming cable TV feed to the rear of the cable box or TV while they are still connected to the rest of the system. If the noise is eliminated by disconnecting the TV cable, the problem is the cable TV ground. You can electrically decouple the cable TV feed from your system with a ground breaking transformer. These are available from many sources. Be advised that many newer, digital cable TV systems require any device in the signal chain to pass a full 1,000 Mhz. Some of the older ground break transformers will not do this. Be sure to check the specifications of whatever device you are purchasing to verify it will pass the digital cable TV signal.

If the noise is from your projector, TV, or monitor, it is most likely caused because the video display device is plugged into a different outlet than the other a/v equipment. It could be on a different circuit as well. These circuits may have two different ground potentials. That is, the resistance to ground is different on each circuit. A difference in resistance to ground from one ground point to another can cause the dreaded ground loop. If you get a ground loop, current flows between the two components. If the current flows through the components internal audio signal ground, you will get a hum.

You can use an isolation transformer, similar to the type used for cable TV ground problems, to eliminate the electrical connection from one component to the other. These transformers are inserted in line with the audio signal connection between the two components. If there is no audio connection between the components, the problem may be current flowing through the video portion. In this case, a video isolation transformer should be used to eliminate the ground loop.

Sometimes power conditioners will stop noise problems by placing equipment on different, electrically isolated outlets. This is done using isolation transformers. Sometimes this is ineffective however, due to the differences in internal construction of different power conditioning equipment. Some safety regulations, such as UL 1950, specify that an isolation transformer is only allowed to isolate the hot and neutral wires; the grounding wire must be passed straight through. If this is the case, the ground loop problem may still exist because many communication circuits are connected to the grounding conductor and not the neutral. In this case, the isolation transformer, or any power conditioner or UPS with an isolation transformer will have absolutely no affect on the grounding problem.

The noise may be generated externally, from a dimmer or refrigerator compressor for example, and coming in through the main power input on the audio video equipment. In this case, a high quality power conditioner may be effective in reducing or eliminating the noise problem. You may also find that one of the signal interconnecting cables in your system is faulty. This can also cause noise problems. Check for this by swapping the cables with one that you know to be good.

You can solve most noise problems in your home theater or multi room audio/video system by taking the systematic, step-by-step approach. Work your way up the signal chain, eliminating each piece of equipment as you go. If you have nothing connected to your speakers except the speaker wiring, and they still hum, the problem is noise induced into the speaker wiring from adjacent power cables. Other than that case, most problems are caused by ground problems, which you can find, and solve, if you take it one step at a time.
