Setting the Sampling Rate Converter

The CDR1000 features a built-in sampling rate converter (SRC), which means digital
sources at sampling rates other than 44.1 kHz, the standard for audio CDs, can be
recorded.
The SRC can convert digital audio within the range 30–50 kHz.
When recording from a 44.1 kHz digital source, the CDR1000 locks to the sampling
rate of the incoming signal. If the signal drifts by more than ±150 ppm (parts per mil-
lion), the CDR1000 automatically activates the sampling rate converter.
The Utility SRC parameter is used to set the sampling rate converter.
1Use the [UTILITY] button to select SRC.
The UTILITY indicator lights up and the SRC setting appears on the display.
2Use the [PREV] or [NEXT] button to set the sampling rate converter to either
ON or AUTO.
3Press and hold the [UTILITY] button, or press another button to cancel Utility.
The SRC indicator lights up when the sampling rate converter is active, that is, when its
set to ON, or when its set to AUTO and activated automatically.
The Utility SRC parameter should be set to ON when recording non-44.1 kHz digital
sources, and set it to AUTO when recording 44.1 kHz digital sources. The SRC does not
affect analog sources connected via the ANALOG IN.
Setting Description
AUTO The sampling rate converter is off unless the 44.1 kHz sampling rate of
the selected digital input source varies by more than ±150 ppm, in
which case it is activated automatically.
ON The sampling rate converter is always on.
Note: When the sampling rate of the incoming signal nears the 150 ppm drift threshold,
the SRC indicator may flash, in which case you should set the SRC parameter to ON.
