Wireless Speaker Transmitter - Buying Guide

!±8± Wireless Speaker Transmitter - Buying Guide

Before we get in-depth into wireless speaker transmitters, let us first understand how wireless speakers actually work:

Every wireless speaker system works on any of the following three systems:

1. Radio Frequency (RF)
2. Bluetooth
3. Infrared (IR)

Radio Frequency

Of these three technologies, RF has been around the longest and is the most widely used. In this system, a wireless speaker transmitter is plugged into the TV/computer/audio device. This transmitter sends out a radio signal at a fixed frequency to the speakers, which in turn, produce sound. This is the same principle on which cordless phones work. While this technology is quite reliable with a strong range, it is prone to disturbance from electrical fields and conflicting frequencies from cordless phones, radios, etc.

Bluetooth

Bluetooth is the latest technology. It works by establishing a remote connection between two Bluetooth enabled devices, which can then be used to transfer data. If you have a Bluetooth enabled phone, you've probably already used this technology to send and receive data. Fast, reliable, and safe from disturbances, Bluetooth is slowly making inroads into the home audio market, though its uptake is hampered by issues of range and compatibility (older audio devices do not support Bluetooth, especially the non-iPodTouch music players).

Infrared

Infrared is probably the least common technology. It works on the same principle as your TV remote by using a particular spectrum of light to send and receive data. If you've noticed, you can't use your TV remote unless it is pointing directly at the TV. Similarly, wireless speakers working on IR need to be directly in sight of the wireless speaker transmitter to work. This obviously limits their portability, and hence, this technology hasn't quite caught on.

Wireless Speaker Transmitters

Most wireless speaker transmitters work on RF. A universal wireless receiver/transmitter plugs into your existing speaker setup (wired) and essentially turns it into a wireless system. It effectively eliminates complex speaker wiring (which, as anyone will tell you, can turn into a labyrinth of cables very, very quickly), and is ideal if you want to set up a home theater system without the hassle, or install a set of outdoor speakers without running a series of wires through your house.

A wireless speaker transmitter typically has a range in excess of 100 feet, with at least 2 audio channels and 6-8 wireless channels to eliminate disturbances (if one RF channel creates disturbances, you can simply switch to another channel). Make sure to check out the total power available with the transmitter. If you buy a low powered transmitter to work with a high-end, high-wattage speaker system, the performance will suffer a great deal. Another key spec is the audio latency. Basically, this is the amount of latency or waiting period between a signal being transmitted by the device and it's rendering by the speakers. Since the signal is being transmitted wirelessly, the latency period is always much more than a regular wired system. The lower the latency, the better.

Sony, Samsung, JBL, etc. all make wireless speaker receivers that work seamlessly with different speaker setups. Here are some recommended wireless speaker transmitter models:

1. Samsung SWA-5000 Wireless Receiver
This elegant wireless speaker transmitter sells for and features 2 audio channels, 6 wireless channels, and total power of 133~167W x 2. The audio latency is a healthy 18ms. A great looking device that will look right at home with your high-end speaker system and LCD TV.
Price: .99

2. Rocketfish RF-RBAUX Wireless Transmitter
Featuring Rocketfish's proprietary 'Rocketboost' technology, this wireless transmitter may well be mistaken for a modem or router instead. While it may not have the sleek design of the Samsung SWA-5000, it is nonetheless, a great performer and works with pretty much any speaker system. The Rocketfish RF-RBAUX has a solid range and will work perfectly well in a large house. Now you can have music playing wirelessly in every room of your house!
Price:

Other recommendations: Sony ALTEC-ALT-A33PC Wireless Delivery System. Works like a charm. Included receiver can store and free up your music for delivery in another room.

4 Tips for Buying Top Branded Home Theater Systems

!±8± 4 Tips for Buying Top Branded Home Theater Systems

Are you thinking of buying a new home theater system or upgrading your existing one?

That can be daunting task. I don't admire you!

There is so much choice out there, how on earth do you think you can make your pick for the best system that suits your preferences?

It is going to be hard work.

It's a pity that its not easier, as owning a home theater is a great addition to the home that turns the humble TV into real entertainment.

But with so many dizzying options out there, it can be a hard ball game - and you might require help finding the way through the maze of fancy names and new technologies.

What I love about home theater systems is you can mix and match different models with different brands. For example you may have a Pioneer DVD player and at the same time have BOSE speakers, as long as they remain fairly well matched then there is no problem.

But putting together home theater components requires a steep learning curve, as you need to investigate and try to find out which brand is compatible with the other.

Here are 4 tips that quickly guide's you to pick your way through the top brands for a great home theater system that meets your preferences

Tip 1. The easy way is to buy a complete home theater then you know for sure the manufacturer has got the system working perfectly.

But with all pre-made packages, though the price may be agreeable, something has to give, and in the case of home theaters that's usually the speakers - and believe me you don't want a great system with inadequate speakers.

The only way to eliminate the problem, is go to the shop, bring along your favorite "acoustic" CD, and try it out on the systems displayed there, listen carefully, if the sound is to your liking then you know the system performs well.

Tip 2. The best brands that will offer top quality include: Panasonic, Sony, Pioneer and Kenwood, also check out brands such as Yamaha, JBL, Denon, Onkyo and Bose.

Tip 3. It's always a good idea to at least investigate the opportunity of selecting the best possible combination of components that will deliver the highest entertainment value.

Say you have a sleek, elegant home theater system from Pioneer - it works like a charm, but the DVD player does not perform well with audio CDs.

But you love your music, so do you pick a Denon instead or simply choose another system with a brand that satisfies your ears.

Tip 4. Then there is the A/V receiver and speakers, which by most manufacturer standards are basic at best. The features and functions are limited when compared to the diverse potential you could get with separate receivers, just make sure the speakers and A/V receiver is compatible.

Summary

It is arguable, but I believe it is fair to say that sound is the most important aspect of the complete home theater experience. You try watching a movie where the screen is crystal clear and the sound is shady at best. It would add up to calamity for you and your family enjoying the home theater.

You just won't take pleasure in the movie and afterwards you would think to yourself "Why did I waste so much money for this home theater?"

The usual sound format is 5.1 surround - that's 5 speakers and 1 subwoofer, this is also known as Dolby Digital. If you want a more quality sound that is good, crisp and clear then try to buy a separate set of surround sound speakers, either of the same brand or from another quality (compatible) manufacturer.
