The DCD-1510AE features the same Advanced AL32 Processing of Denon’s
high-class DCD-2010AE. This technology dramatically enhances information
volume from the CD to produce a sound more faithful to the original.
The DCD-1510AE also has a USB port for directly receiving digital tracks
stored on an iPod or USB memory. When digital audio signals are input
from an external device, they pass through Advanced AL32 Processing and
other circuits developed by Denon to maximise sound quality, allowing
you to experience a depth of sound not possible with the portable audio
device by itself.
