D150, the Front Panel Display indicates the Sampling
Rate (refer to figures 86 and 87 for PCM Signals).

Figure 84
Figure 85
Figures 88 and 89 indicate a Sampling Rate of 64 or
128 times the Sampling Rate of a CD Disc for the
incoming DSD Digital Audio Signal.
The Sampling Rate and the Bit Rate is determined by
the original recording, the Application Output Format
(when available) and the McIntosh-HD Control Panel
Settings.
Note: In general, when the original music is recorded
at a higher Sampling Rate, the result is usually
more detail in the music. However, this higher
rate results in consuming larger amounts of stor-
age space. The Sample Rate usually should be set
to match the Sample Rate of the music recording
being played back.
There are many third party Applications (besides
Applications like Windows Media Player) for steam
-
ing music from the computer to McIntosh D150 USB
Input. An example of just one of the available applica-
tions is “JRiver Media Center”.
