Know Auto Sound System Basics

Know Auto Sound System Basics

These are the basics you need to know for all car stereo systems. Now that you have a better idea what all these different terms actually mean, you should be able to shop intelligently for your new car stereo system. Just remember, as always, while you get what you pay for, you don’t necessarily have to have the absolute best (and most expensive) parts for a good sound. More often than not, a midrange product will provide the best bang for your buck. And remember, it’s all modular! You don’t HAVE to buy every piece all at once. You can start with the head unit, and simply wire it’s built in amplifier into your factory car stereo speakers. Add a sub and an amp later if you want, or replace the factory speakers with higher quality ones, it’s all up to you.

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

Posted: 04 Jul 2011 01:50 AM PDT

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

  • One pair of 2-way indoor/outdoor speakers
  • Acoustic-suspension design for clear sound and taut, controlled bass response
  • 120 watts maximum power capacity, 35 watts nominal
  • 5-inch high-compliance, polypropylene, mica-filled woofer and .5-inch PEI dome tweeter; magnetically shielded and water resistant
  • Each speaker measures 5.41 x 10.125 x 6.16 inches (W x H x D)

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.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.

Their acoustic-suspension cabinets are sealed to prevent undue resonance or tubby, tuneless bass, which often results from low-cost ported designs.

With a nominal impedance of 6 ohms, the speakers will work nicely with amplifiers up to 35 watts per channel, nominal, or 120 watts, peak power. They boast a frequency response of 80 to 40,000 Hz (+/-3 dB), giving you decent bass output for their compact size and unusually extended high-frequency response for your most demanding digital media. For indoor use, you may want to augment their performance with a subwoofer to deliver deeper and more powerful bass; be sure to select one with a variable crossover so you can tailor its upper frequency to effectively “take over” at the point of the NS-AW150s’ lowest deliverable frequency.

The speakers are magnetically shielded, so you can place them on or near a TV or video monitor without fear of picture degradation from their magnetic fields. Five-way binding posts simplify connection with several different terminations of speaker cable (including banana plugs), and the NS-AW150s even come with two lengths of cable to get you started.

While you wouldn’t want to leave the speakers exposed on, say, the deck of a boat, they are water resistant and designed to withstand light wind and rain–a benefit of their sealed enclosures and rugged metal grilles. The speakers come with mounting bases and brackets.

Two speakers, two lengths of speaker cable, speaker bases, mounting brackets, a warranty card, and a user’s manual.

Providing Power for the Digital Revolution is the broadly defined mission of Harman Kardon. The popularity of computer-based, compressed-audio formats, such as MP3, has created the need to add a new and otherwise incompatible component to home entertainment systems: the PC. Harman Kardon’s DAL 150 EzLink fills that need by providing a digital link that connects the USB port of a compatible PC to the coaxial digital input of a receiver or processor. EzLink can convert an MP3 file or bitstream to PCM format for playback on many audio products. Your receiver may then process the selection using one of the many available surround modes, such as Logic 7. When used with a Harman Kardon A/V receiver, EzLink may be set to simply pass the MP3 bitstream through to the receiver, for onboard MP3 decoding. At Harman Kardon, the future is now.

Set Up a Home Office Wireless Sound System

Posted: 03 Jul 2011 04:54 PM PDT

Set Up a Home Office Wireless Sound System

If you’ve used any sort of wireless device — telephone, laptop, PDA, or even a simple remote control — you know how convenient it can be. You’re not tethered to … well, to anything. And you’re free to move around while doing your work.

One area that’s ripe for wireless is a home or office sound system. Once a dream, it’s now relatively cheap and easy to set up such a system. Imagine being able to listen to your digital music without wires – you’ve probably got most of the components already. For a couple of hundred dollars or less, you can have a great wireless sound system.

Why Go Wireless?

Obviously, the main advantage to going wireless is to cut down on all of those pesky cables that have been the bane of audiophiles for decades. With

wireless, you can place your speakers just about anywhere in your home without being limited to the length of wire that connects back to your audio system.

If you’re like many people these days, you’ve probably got more music in a digital format like MP3 than you have on CD. Maybe you’ve ripped your CDs and/or

downloaded music from the iTunes Store or other popular online music vendors. It’s easier to play these files directly from your computer instead of burning

them on to a CD and having to fumble with those disks.

And let’s face it: no matter how good your PC speakers are, they’re no match for a decent set of stereo speakers. Piping your music to speakers, even those

in another room, will only enhance your listening pleasure.

http://www.papatek.com/Cell-Phone-Accessories/
How It Works

A wireless sound system works sort of like radio. A transmitter is connected to a device — usually a computer — that stores and plays your music.  A

receiver, plugged into a stereo or a set of speakers, picks up the signal from the transmitter. There are two ways in which signals can be sent from the

transmitter — analog and digital.

Analog is similar to FM (Frequency Modulation) radio. The signal is strong and constant, but the frequency of the signal changes slightly based on the

information being sent. If you still listen to terrestrial (as opposed to satellite) radio, you’re probably familiar with FM.  The quality of the signal is

good and signal strength is decent, though it can be affected by barriers (like walls) in the way of the signal.

Digital, on the other hand, converts sounds to packets of electronic data. In the case of a wireless audio system, this data is sent over the air from a

transmitter and the data is converted back to audio when it reaches the receiver. It’s really the same principle as a wireless Internet connection.

Wireless devices, like the ones described in this Tech Tip, operate over a specific range of frequencies — usually between 900 MHz to 2.4 GHz. This range of frequencies is used by most consumer wireless devices. That means a consistent level of signal quality, but it can also lead to interference from other devices. Luckily, the hardware used in setting up a wireless sound system enables you to select different frequencies to avoid or at least minimize interference.

Ways to Go Wireless

There are a couple of ways you can go wireless. If you’re an iPod user, you can turn your gadget into a music transmitter using the Wireless Music System for iPod by Logitech. This device clips to your iPod, turning it into a transmitter. You connect a small base station to your stereo or a set of powered speakers and you can use the iPod’s controls you can shuffle through songs or play your favorite play lists.

You can also get FM transmitters for certain makes of MP3 player. The transmitter — like iriver AFT-100 or the Belkin TuneCast II — plugs into your MP3 player and literally sends the music on the device to an FM receiver. That receiver could be a stereo or even a car radio. Essentially the transmitter turns your MP3 player into a short-range radio station. The range of these devices is limited – about ten to 30 feet. But over those distances, the signal is clear and has little or no interference.

Or, you can use a desktop computer (which is often called a media server) to store and broadcast your audio. You don’t need an up-to-date, lightning fast system with the latest version of your operating system (although that does help), either. An older computer running Windows XP and with a decent amount of memory and a fair sized hard drive is usually more than enough. I know at least two people who turned old eMachines desktops with 512 MB of memory and 80 GB hard disks into serviceable media servers. Using a software media player — like Windows Media Player, iTunes, RealPlayer, or WinAmp — you can create play lists or play all of your audio in bulk.

A popular way to turn a PC into a sound system is the Logitech Wireless Music System. This device consists of two parts. The first is a small transmitter that you plug into a USB port on your computer. The second is a receiver that you connect to your stereo or a set of wireless speakers. Then, just fire up the media player on your computer and you’re ready to go.

http://www.papatek.com/USB-Wireless-LAN-Adapter
The Linksys Wireless Media Center Extender not only does audio, but also video and Internet radio. The Extender looks like a DVD player with a small antenna at the back. You connect the Extender directly to your TV or stereo, and then install the software that interacts with the Extender on your PC. To use the

Media Center Extender, your PC needs to be running Windows XP Media Center Edition and you’ll need to have a wireless network up and running.

Apple has always had an edge over PCs in multimedia. If you have a recent Mac and a high-speed Internet connection, you can turn that Mac into a media server using an AirPort wireless base station. Just plug the AirPort base station into your stereo or your speakers, and let your Mac and the iTunes software do the rest. According to Apple, iTunes will automatically detect the base station and you can start playing your tunes immediately. However, at , the AirPort base station isn’t cheap, especially if you want to have your audio piped to multiple locations in your home.

Speakers

Getting good sound from a wireless system – or any audio system for that matter – is partly a matter of having a good audio source to work with and mainly

a matter of having a decent set of speakers.
The great thing about a wireless sound system is that you don’t necessarily need to buy a new set of speakers. If you have a stereo, then you can use the

speakers that you already have. If course, if you can afford it, a new set of speakers can’t hurt. The only problem with using stereo speakers is that you’re

still restricted by the speaker cables. Your sound source can be anywhere, but the position of the speakers is limited to the length of cable connecting them

to your stereo.

Wireless speakers, on the other hand, can free you of that limitation. You can (within reason) position the speakers anywhere you want in your house or even

outside. Most are light enough that you can position them anywhere. With most wireless speakers, however, will need to be positioned near an electrical

socket — this will limit where you can position your speakers. There are battery-powered wireless speakers, but most of them only hold a charge for about

four hours. As the batteries run down, so will the quality of the audio that’s coming out of them.

You can expect to pay several hundred dollars for a decent set of wireless speakers. Models from Panasonic, for example, can cost anywhere from 0 to

,700 dollars. Ones from Acoustic Research or JBL will cost quite a bit more. But, as with anything else, you get what you pay for. The quality of the sound

will be better with a slightly higher-end set of speakers. That said, you should really only buy what you can afford and if you can afford it.
You can usually find some pretty good bargains on online retailers – papatek.com, for example.

Of course, how you position your speakers in a room is almost as important as choosing the right speakers. How you position your speakers will depend on thesize of the room and its layout. You can find some good advice on this topic here and here.

A Few Caveats

Remember that a wireless sound system has a limited range — from around 30 feet to 100 feet, maybe a bit more. This isn’t a problem in the average home, but if you want to play music outside then you might experience a drop in the quality of the sound.

Speaking of putting your speakers outside, while it may seem like a good idea to have your favorite bit of music playing during a BBQ or garden party,remember that many speakers aren’t meant for use outdoors. They could get damaged by the weather or careless guests. If you’re using battery-powered speakers, remember that the life of the batteries is limited — probably (hopefully!) shorter than the duration of your party.

On top of that, the sound that is sent to speakers might not arrive at the same moment, depending on how far the from your media center the speakers are set.

In most cases, you might not notice any problems with the sound. Sometimes, though,

The Satellite Speakers have Wall Hanging Capability and Conventional Speaker Bracket Compatibility. All speakers have removeable Grill Cloths and are Magnetically Shielded.The Yamaha NS-SP1600 5.1-channel Home Theater Complete Speaker System gives you the convenience of an all-in-one system with high-quality speakers. Not only are these speakers perfectly matched for acoustics and design, but they take advantage of unique technologies that Yamaha originally developed for its high-end speakers. With an amplifier or receiver and a DVD player, you’ll enjoy movies with sensational surround sound. What’s more, even with their extremely high quality, these speakers are small enough for easy positioning in rooms of any size.

The satellite (main, rear, and center) speakers have a two-way acoustic suspension design with one coaxial two-way driver plus one full-range driver. The center speaker has the same coaxial two-way driver, and also includes dual cone full-range drivers. All of these speakers are rated at 100 watts maximum output, more than enough for dynamic movie sound. The 100 watt powered subwoofer uses two of Yamaha’s unique power-bass technologies: QD-Bass and advanced YST. Together they combine power and detailed, accurate reproduction in a compact unit.

QD-Bass Technology uses down-firing drivers with square, pyramid-shaped reflective plates to radiate the sound efficiently in four horizontal directions. The reflective plates (not used in competitor’s down-firing subwoofers) negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit. Also, most other systems use circular cones, but by radiating in four directions to avoid the legs of the cabinet, QD-Bass reduces turbulence caused by reflection from the legs. Changing the height of the square pyramid varies the acoustic load, permitting relatively simple high-cut adjustment and improved bandpass properties. The QD-Bass system provides extraordinary power and smooth frequency response from an extremely compact unit. It also allows greater freedom of placement, since the sound radiates with equal effectiveness in all directions.

Yamaha’s patented Advanced Active Servo Technology (Advanced YST) generates incredible bass from small speaker enclosures. Advanced YST is the ideal method of combining amplifiers and speakers for maximum performance. This system’s advanced negative impedance converters intelligently adjust the negative impedance generation as the speaker moves, creating a hard, rigid cone that prevents deep resonant waves from leaking out of the speaker cone. This means the full power of the waves is forced out through the air port, resulting in clear, powerful bass.
