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)
3. Infrared (IR)
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 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 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
Be Free with Wireless Speakers
Are you tired of laying wires through your house, creeping through small places just to get the right sound effect? Wireless speakers are the answer to your headaches. With wireless speakers you gain the freedom to move your music to where you want it to be without the hassles of cables. Planning to have a party outside? Don't move your whole entertainment system outside while you can make use of outdoor wireless speakers which can move right along with the party.
Want to have hi-fi quality sound through your laptop computer? Why should you be tied to wires while using a portable computer? Make use of wireless speakers to give you the freedom to work or play on your computer where you want to, while having the high fidelity sound you deserve.
Here are a few examples of how you can use wireless speakers to improve your way of living.
- Listen to your favorite music collection while taking a bath.
- Have a BBQ or party outside without having to move your whole stereo system.
- You can store all your favorite music on your computer and listen to it anywhere in your home.
- Listen to music while working in the garden.
- When your computer is doing certain time consuming tasks, have it play a sound when it is done with the task or when there is an error and have your wireless speaker notify you while you are lying next to the pool.
- Get the perfect surround sound effect by having the freedom to move the speakers to exactly the right spots without getting tangled in wires.
- Let your computer notify you of upcoming tasks or appointments by playing a sound through your outdoor wireless speakers, while you are washing your car.
- Let your wireless speaker notify you discretely of intruders by connecting it to your alarm system.
- Use you wireless speakers as a portable intercom system.
There are however a few things you need to watch out for when shopping for wireless speakers. Some are listed here:
Some wireless speakers may interfere with other wireless devices in your house like cordless phones. A good wireless speaker system will allow you to tune it to a different frequency to overcome these interferences.
Battery life is not always too great on wireless speakers, as it consumes power to drive the speakers, internal amplifier and RF receiver. So, if you want to use your wireless speakers for extended periods of time, it may be wise to make use of the AC power adaptor. Now this may not always be practical - the whole idea of wireless speakers is to get rid of the wires. Rechargeable batteries might be the answer and some of the models even come with rechargeable batteries -something to consider when you need total freedom, even from power outlets.
Most wireless speakers can work fine within a range of 150 to 300 feet from the transmitter. (Which would be located at the source of sound i.e. your hi-fi or computer) The RF frequency is high enough for it to work through walls and furniture. You do not need a line of sight, but bear in mind that obstacles weakens the signal, and the more obstacles between the transmitter and receiver, the shorter the range will become.
