The CS-245DAB is Stylish CD Mini-System with USB (Universal Serial Bus), DAB+, & iPod/iPhone Playback. As well as playing regular CDs & MP3-encoded CD-Rs, the CS245 DAB system features a built-in DAB+ tuner for unlimited access to digital radio. But the playback options dont end there. On top of the CS-245DAB is a digital dock for iPod/iPhone, & on the front-side is a USB (Universal Serial Bus) port that lets you play audio from a flash drive. As always with Onkyo, construction is top-notch. The player/receiver body is supported by seamless steel front & side panels designed to reduce vibrations. The CS245 DAB speaker cabinets-edge-rounded, like the main body-are slightly tapered to minimize internal standing waves. & the two-way speaker design incorporates a 10 cm bass-reflex woofer & a balanced-dome tweeter that help deliver a nuanced & musical performance.
