Surround sound is a fantastic way to experience the latest movies, television shows, and video games. It creates the sensation that the listener is in the middle of the action seen on the screen. A wireless surround sound system provides the same effect as a wired system but does not have the long lengths of audio cable that are so difficult to hide. The speakers can also be placed outdoors without having cables running out of doors and windows. A wireless system usually has the same features of a wired system and takes even less time to install and setup. The audio quality is very good and only an audio enthusiast would hear any difference when compared to a wired system.
A wireless surround sound system can be used for a high definition television or home theater setup, but many people still prefer a conventional wired system. The original wireless systems had poor audio quality and that reputation has persisted, despite the improvements that have been made in the years since then. Wireless systems are ideal for use outside the home, as they are easy to setup and can be quickly moved back inside. Wireless speakers can be mounted around covered patios and gazebos while keeping the expensive receiver inside the house. These systems are also good to use with computers and video games consoles, as many games now have excellent surround sound capability.
When choosing a wireless surround sound system, there are several features that should not be overlooked. It should support all the common audio formats, including DTS, Dolby Digital, and Dolby Pro Logic. The satellite speakers and subwoofer should have adequate power output and frequency response. The satellite speakers should be well shielded to prevent interference from their power cords. As well, interference from other wireless devices can be reduced if the system uses frequency hopping technology, like Bluetooth. Another good feature to have is an audio line input for a portable CD and MP3 player. Some systems also have a desktop control unit that is a useful replacement for the remote control.
The conventional way to setup a sound system is to connect the speakers to the receiver with audio cables. The speakers do not require separate power cables because the audio cables carry enough power to drive the speakers. A wireless surround sound system is different because the audio signals are sent using wireless technology, so its speakers do require power cables. Many people wrongly assume that these systems are free of cables and that the speakers are powered by batteries. While this is certainly possible, it is not a practical scheme because the speakers use a lot of power and they would quickly drain the batteries.
Most of the time spent installing a sound system goes into finding ways to hide the audio cables from view. Running long cables from the rear speakers back to the receiver can be a problem is some rooms, particularly open-plan living areas. Home owners often find that they cannot hide all the cables, or the cables need to cross a doorway, or that there is some other obstacle in the way. It may also be impossible to put the cables inside the roof, wall, and floor spaces. A wireless surround sound system eliminates this problem, provided there are enough wall sockets for all the speakers and they are close to them.
The typical range of a wireless speaker is about one hundred feet, allowing plenty of room to move them about. The position of the speakers makes a huge difference to the overall surround sound experience. Choosing locations for the speakers can be difficult because the most convenient spot is often not the best one. A wireless surround sound system provides more flexibility in locating the speakers. They can be placed on furniture, partitions, window ledges, or mounted on the walls. Some speakers even have stands that rotate so they can be used as wall brackets. Most rooms have plenty of wall sockets and finding one near a speaker is usually not a problem.
