Multi-Channel home theater systems can be classified into wired and wireless systems, with wired systems typically performing better due to the loss of speaker cable and the absence of an AVR. HTiBs are a type of wireless system that comes with all the necessary speakers and an AVR in one box, but requires custom-building for high-end performance.
True surround sound systems and simulated surround sound systems can also be distinguished. True surround sound systems have each channel having its own speaker, while wireless systems often provide virtual surround sound without each channel having its own speaker. Wireless systems often include a soundbar and a subwoofer, which can replace three front channels or more. Some wireless systems may also include a soundbar, wireless SUB, and two wireless satellite speakers.
For surround sound audio formats, such as Dolby Digital 5.1, DD+, and Dolby Atmos, are required for a multi-channel home theater system. To enjoy surround sound, the material used must have one or more surround sound audio tracks saved on it. Blu-ray discs often support two or three required surround sound formats, and optional formats like DD+, Dolby TrueHD, DTS HD, DTS HD Master Audio, Dolby Atmos, and DTS:X.
To install a multi-channel home theater system, you will need a media (source) that supports surround sound, an AVR, and speakers. Connecting all sources to the AVR requires HDMI cables, optical cables, coax audio cables, RCA cables, and other cables depending on the quantity and type of sources you want to connect. You will also need a speaker wire to connect your speakers to the AVR, which can be difficult to choose the correct length, gauge, and type.
After attaching the speakers, you can start the calibration process using calibration microphones included with most modern AV receivers. The software will handle the rest, allowing you to enjoy surround sound after the calibration is complete.
