Each and every year latest designs of home theater kits are introduced. There are commonly only some minor particulars or capabilities put in or changed.

A number of transmitters furthermore accept line-level signals. Electrical power is typically supplied by a wallwart which hooks up to a mains power wall socket. Every cordless amplifier can be located very close to every loudspeaker.
