Shopping Tips for iPod Speakers

There are many things to watch out for when buying a set of wireless speakers. However, you don’t have to be an expert to be able to pick your ideal speaker. I will offer some advice to help you avoid unpleasant surprises when picking your wireless speakers.

How Do Speakers Produce Sound? (A Helpful Beginner's Guide) – My New  Microphone

Running the wires to set up a new pair of speakers is often a hassle. If your home is not prewired for audio you may end up drilling holes and doing a big cabling project. Wireless speakers promise to eliminate the speaker wires. Regular speakers require an external audio amplifier to be driven . On the other hand, wireless speakers have their own built-in power amplifier. For medium to high audio power amplifiers, these speakers typically have to be plugged into a power outlet. This means that these speakers can only be placed in locations that have power. This typically is not much of a problem if you plan on putting speakers in another room of your house. However, to eliminate the power cord, some wireless speakers are powered by internal rechargeable batteries. Speakers with moderate audio power, however, require fairly heavy batteries which makes logging the speakers to a place where the batteries can be recharged somewhat of a hassle. In addition batteries will age over time and need to be replaced.

Depending on your application, you want to select speakers with the correct audio power that is sufficient for your environment. Depending on whether you are planning to use the speaker indoors or outdoors, you may want to go with a speaker that is waterproof or at least water resistant.

Next, make sure the transmitter offers the correct audio inputs for your audio equipment. First check what type of audio outputs are available. Then check that your transmitter can connect properly. Obviously if the transmitter has more than just one type of input, you will have more flexibility in case your audio equipment changes down the road. Some more sophisticated transmitters also come with an iPod cradle. This cradle allows streaming of music directly from an iPod or iPhone and also acts as a recharger base. However, if you have another MP3 player, you can still stream your music by connecting to the transmitter through a standard line audio input which almost every transmitter has. Some transmitters have an audio input with a volume control. This allows the transmitter to adjust to virtually any audio device, regardless of the audio output level.

Wireless speakers typically employ either analog or digital wireless audio transmission. Analog transmission typically at 900 MHz uses a method which is similar to FM radio. Digital wireless speakers use a transmission which is more similar to sending the contents of a CD as data and normally transmit at 2.4 GHz or 5.8 GHz. By transmitting audio as data, noise and distortion which are common problems of analog audio transmission are eliminated. With the growing number of wireless gadgets, there is more and more wireless interference. Modern wireless speakers typically utilize some sort of error correction scheme. This method allows the speakers to be able to tolerate interference without audio dropouts.

Are you trying to set up a new home theater system or some speakers? The easiest way is to hire a qualified installer to help you. However, you may consider doing the setup yourself. I am going to outline the basic setup procedure and give some tips to help avoid some common problems.

Your home theater system will come with usually 5 or 7 speakers – 1 central speaker, 2 front speakers, 2 rears and 2 sides (in case of a 7.1 system) as well as a woofer. It also includes a central component. This component will drive all of your speakers. This component is also called surround receiver and acts as the central control of your home theater system.

Locate this receiver in a place that minimizes the speaker cable run to each speaker. Choose a location that is not far away from your audio source or TV because you will need to connect the receiver to your source.

It is not too difficult to make the connections between your receiver and TV or DVD player by using a fiber optical cable. Connecting your satellite speakers takes a little bit more work though.

You won’t need as much speaker wire if your speakers are wireless. Some kits come with all-wireless speakers while others only have wireless rear speakers. For all other speakers, start by measuring how much speaker cable you require. You may want to add some extra length for safety. In most cases, you won’t be able to run the cable in a straight line to your speakers. You may need to consider carpets, furniture etc. Thus make sure you include all of these extra bends in your calculation. If you are planning to drive a lot of power to your speakers then make sure you pick a cable that is thick enough to handle the current flow. Your subwoofer usually will be an active woofer. This means that it will accept a low-level audio signal. You can connect your woofer via an RCA cable.

The satellite speakers each connect via a speaker terminal which is usually color coded to help ensure proper polarity. Most speaker cable will show one strand in a different color. This is essential since it will help ensure the correct polarity of the speaker terminal connection. Simply attach the different-color strand to the speaker terminal which is colored. Similarly, each speaker output of your surround receiver is color coded. When attaching the cable to your receiver, observe the right polarity once again. This will keep all of your speakers in phase.

If you are using wireless speakers, there will be a short audio delay incurred during the audio transmission to the speakers, also known as latency. Ideally, all speakers have the same latency and thus are in perfect sync. If you have both wireless and wired speakers, the wireless speakers will be out of sync with the wired speakers. Therefore you will need to delay the audio going to the wired speakers by tweaking your receiver. The amount of delay should be equal to the latency of the wireless speakers.
