Chapter 17—Digital Audio I/O
Care must be taken when transferring high-resolution digital audio directly from the
D24's COAXIAL OUTPUT to a low-resolution device. In the following example, the
20-bit digital audio from the D24 will be truncated by the 16-bit DAT deck, resulting in
distortion and graininess.

If the device receiving the high-resolution signal does not feature digital dither, an
external digital audio processor with digital dither function can be used to truncate the
signal, as shown below.
