Get the Hi-Fi features you want, but in a small package. The MHC-GX450 includes a 3 Disc CD Changer, CD-R/CD-RW1 and MP3 playback2 capability, 2 Way Main Speakers with Hybrid Dual 5 Woofer, Game Sync Mixing, dual cassette decks, and 30 station presets. Game Sync Mixing lets you control the volume of your music and game sounds, so you can get just the right mix. The CD-R/CD-RW3 and MP3 playback4 capability makes it possible to play your burned CDs and personal compilations, while the dual cassette decks add even more flexibility. And, the MHC-GX470 may be a Mini Hi-Fi system, but it still has 400 Watts of total power, with a 150 Watt Subwoofer.
