Great audio is what really makes home theater rock, and the HTP-220 brings it on. The VSX-D411 digital A/V receiver features Crystal digital signal processing and delivers 100 Watts to each of five channels. Dolby Digital 5.1 and DTS 5.1 surround sound processing provide spectacular decoding of movie soundtracks, and for "Party Mode", 5-Channel Stereo routes the full-frequency stereo signal to five speakers at full 100-watt-per-channel power. The five speakers (each with 3-inch piezo tweeter and midrange woofer and a high-frequency wave guide) and the self-powered 100-Watt subwoofer are all acoustically matched for optimal sound. A front-panel quick-setup function and remote control are provided.
