The process of installing multi-channel audio speakers in home theater products is quite tedious and suppliers have invented new products and technologies like wireless surround sound speakers or surround sound wireless headphones recently to help simplify the installation. I am going to take a look at a few of the latest technologies that were designed to make setting up home theater systems a snap. I will highlight what to look out for when making your buying decision.
Therefore, home theater setups have turn out to be fairly difficult. Running cables to remote speakers also is often undesirable because of aesthetic reasons. Manufacturers have lately released new devices and technologies. These products were developed to help simplify the setup of home theater systems.
The first approach is creating so-called virtual speakers by applying signal-processing to the audio and introducing phase shifts and special cues to those audio parts that would normally be broadcast by the remote speakers. The sound is then sent by the front speakers along with the front speaker audio components. The signal processing is modeled after the human hearing. It uses the knowledge about how the human ear can determine the origin of sound. Due to the signal processing, the viewer is deceived into assuming the sound is coming from virtual remote surround loudspeakers.
The first solution is named virtual surround sound. This approach will take the audio components which would ordinarily be sent by the remote speakers. It then utilizes signal processing to those components and inserts special cues and phase delays. Then these components are mixed with the front speaker sound. The sound is then sent by the front speakers together with the front speaker sound components. The signal processing is modeled after the human hearing. It uses the knowledge about how the human ear can determine the source of sound. The viewer is in effect deceived into believing the sound is originating from a location other than the front speakers.
A different option for avoiding long speaker cord runs is to employ wireless surround sound products or wireless loudspeakers. A wireless product includes a transmitter and one or several wireless amplifiers. The transmitter connects to the source. The wireless amplifiers connect to the remote loudspeakers. This transmitter will usually have line-level and also amplified loudspeaker inputs. Ideally it should have a volume control to adjust it to the audio source.
Whilst some wireless speaker kits have a wireless amplifier that connects to two speakers, other devices offer individual wireless amplifiers for every speaker. The most advanced wireless kits employ digital transmission to eliminate signal degradation. In multi-channel audio devices, it is important to pick a wireless solution with a latency of merely a few milliseconds. This will ensure that the audio of all speakers is in perfect sync. Otherwise there will be a noticeable echo kind result. A number of wireless devices work at 5.8 GHz which offers the advantage of less competition from other wireless devices than products employing the crowded 900 MHz or 2.4 GHz frequency band.
Another solution are side-reflecting loudspeakers. These kits are also referred to as sound bars. The audio that would ordinarily be sent by the remote speakers is instead sent by loudspeakers at the front. These front loudspeakers broadcast the sound at an angle. Then the audio is reflected by the side and rear walls and appears to be coming from besides or behind the viewer. This option works best in a square room with minimum interior design and obstacles. It will not work well in many real-world scenarios with diverse room shapes however.
