Introduction

Thank you for purchasing the Digital Link Sound System (XDP-MU110).

This system allows you to digitally integrate an iPod/iPhone into your existing car audio unit. You can enjoy exciting sound from your car audio unit and iPod/iPhone via this system, which features sound settings optimized for your vehicle type by using Sony's original digital sound technology.

The DSP master unit makes a natural “front sound field” possible, so that you can feel bass as though it comes from directly in front of the driver’s seat even though the subwoofer is located at the rear of your car, e.g., in a cargo area.

There is also a digital connection for an iPod/iPhone so that you can enjoy high quality sound in your car without noise/distortion.
