USB Music Playback
When the USB When the Input is selected on the
McIntosh C53, the Front Panel Display indicates the
Sampling Rate (refer to figures 102 and 103 for PCM
Signals).
Figures 104 and 105 indicate a Sampling Rate of 128
or 256 times the Sampling Rate of a CD Disc for the
incoming DSD Digital Audio Signal.
The Sampling Rate and the Bit Rate are 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 Ap-
plications like Windows Media Player) for steaming
music from the computer to McIntosh C53 USB Input.
An example of just one of the available applications is
“JRiver Media Center”.
Reset of Microprocessors
In the unlikely event the controls of the C53 stop func-
tioning, the microprocessors can be reset by perform-
ing the following:
1. Press and hold in the STANDBY/ON Push-button
until the LED above the STANDBY/ON Push-
button illumination is extinguished. Then release
the STANDBY/ON Push-button.
2. To switch the C53 back On, press the STANDBY/
ON Push-button.
Note: This can be performed with the C53 On or in the
Standby Mode.
