摘要
A subwoofer (72) is equipped with a wireless receiver (80) to receive signals containing information for a Low Frequency Effects (LFE) channel and information for both surround channels. In one form, the LFE is added to one or both surround channels to provide a stereo surround signal (containing both surround channels including a multiplexed LFE channel). The subwoofer (72) utilizes the LFE channel, powers surround speakers (74, 76), and passes the surround signals to respective surround speakers. A receiver (66) multiplexes LFE signals into either one or both surround sound audio channels. A digital RF transmitter (70) of the receiver transmits the combined subwoofer/surround channels to the wireless receiver (80) of the subwoofer. The remote subwoofer is connected to a power source (78). The surround speakers (74, 76) are connected to the subwoofer so as to receive the surround channels and be powered thereby.
