All other tabs in this left hand list can be used but this will result in the loss of Bit
Perfect playback, which for maximum fidelity, is the goal of these adjustments.
B-Clip Protection should be checked as this will prevent digital overload which can
produce harsh sounds. Volume Leveling will also protect against clipping.
In the center of the screen output formats are set. This is two columns of input, the
original file encoding, and output what is sent to the DAC. By checking No change, the
McIntosh USB input will see each file in its’ original format. If all the formats are set to
192,000Hz, as an example, this will only increase the file size or ‘container’ of the
original music file with no change in sound quality.
Music files referred to as DSD64, DSD128 or DSD 2.3MHz and 5.6MHz can be used
with McIntosh 32/192, High Speed USB inputs running JR-20. JR20 will transparently
convert and output these DSD files over high data rate PCM.
This screen shot is of a normal 16 bit, 44.1 CD rip to the HD playing. At the bottom of
the page the actual peak level is showing 17% which changes the volume changes in
the course of the song playing. Internally, JRiver is processing this CD file at 44.1KHz
and 64 bits. The 64bit Internal processing allows Volume Leveling mentioned above
since the maximum music file size of 24 bits is far exceeded by the computer so files
can be volume leveled since the computer’s processing is a much larger ‘bit box’.
Clicking on the red X in the upper right hand corner will close the DSP studio and return
to the options box.
