In addition to a re-conceptualized faceplate design with blue accents, a USB port is available to enable connection to data storage devices for MP3 playback. The AUX port compatible with portable media devices is still available as well. Power output to the 4 channels has been increased to 60 watts each. Most of the internal features are the same, and include separate bass and treble controls, balance and fader controls, and a loudness control for better sound at lower volumes. RCA outputs also enable further expansion of the system into external amplifiers.
