DESC: The CQ-C1305U will play MP3's and WMA files from your recorded CD-R/RW's, so you can bring your music collection with you. A rear auxiliary out put can either drive a set of rear speakers or can be used to drive a subwoofer. If, like many people, you have some sort of MP3 player, you can easily plug it into the CQ-C1305U as well. A standard 3.5mm front auxiliary input will accept a standard adapter cable from your player's headphone output.
