DESC: The Panasonic CQ-C5301U will impress you with its performance and wow you with its cool looks. The display on the CQ-C5301U is a blue positive display instead of the traditional negative green or blue. We found this type of display to be very visible and easy to read. To complement its awesome appearance, the CQ-C5301U is packed with an impressive array of features including MP3/WMA playback with ID3 readout, a built-in spectrum analyzer, SQ3 (3-Band Sound Quality) equalizer, three sets of preamp outputs, auxiliary input, and CD changer control.
