I will look at the newest trends to see which devices really work. This, though, has all changed with multi-channel audio. As a result installing a home theater has turn out to be pretty intricate and long speaker cable runs are often undesirable for aesthetic reasons. Since the signal processing is based on how the human hearing detects the origin of sound, the audio components which underwent signal processing can be mixed with the front speaker components and broadcast by the front speakers. One more method for avoiding long speaker cord runs is to make use of wireless surround sound kits or wireless home theater speakers. A wireless kit includes a transmitter and one or a number of wireless amplifiers. The wireless amplifiers connect to the remote speakers. A transmitter volume control helps maximize the dynamic range and eliminates clipping of the audio inside the transmitter.
As some wireless speaker devices come with a wireless amplifier that connects to two speakers, other products offer separate wireless amplifiers for each speaker. More sophisticated devices employ digital audio transmission to completely preserve the original audio. These systems are also known as sound bars. The audio that would ordinarily be sent by the remote speakers is instead sent by speakers at the front. These front speakers broadcast the audio at an angle. The result heavily depends on the interior, particularly the shape of the room and the decoration. It will function well for square rooms with no obstacles and sound reflecting walls.
