High-End Performance...
It's the age of personal, portable electronics; everyone carries their music with them. Whether you're using iTunes for low-bit-rate downloads or high resolution music files just connect your computer to the ADL Stride with one of our matching ADL Formula 2 USB cables or the new i-D35SP analog stereo cables. When you're on the road plug your music player’s analog headphone output into the line input of the Stride and open the player’s volume to maximum and use the volume control on the Stride.

For higher resolution all-digital signals simply connect the Stride to your computer’s USB port. The USB port charges the battery and you can listen to music while it’s charging!
