The Resampler menu contains all settings related to SIRIUS G2.1’s resampler. Please turn
the rotary knob clockwise or counter-clockwise to highlight an option, and push the
rotary knob to select it.
All signals coming from any input will first be converted into a high frequency multi-bit
data stream for jitter removal and for any user-enabled processing. The processed data
will then be resampled to your selected output frequency, and sent out of SIRIUS G2.1.
This processing structure means
SIRIUS G2.1 does not have a passthrough mode
.
•
“Enable Resampler”
: Enable/disable the resampler.
•
“DoP Marker”
: Chooses between DSD-over-PCM markers. (Early versions of DoP
enabled the use of 0xAA, while most devices now accept 0x05/FA.)
•
“Filter Mode”
: The resampler has four built-in filter modes, each employing five
digital filters optimized for the corresponding sampling rates. Developed using a
combination of objective data models and subjective testing, these modes
optimize sonic quality for varying music types and formats:
Precise
: A traditional
filter design using a single filter algorithm for all sampling rates. Precise mode
provides the most exacting sonic representation of the source material.
Dynamic
:
With the same pass-band and stop-band performance as Precise mode, but
providing less group delay, Dynamic mode is the ideal balance between
measurable precision and subjective quality.
Balance
: Balance mode is designed
to achieve minimum pre-echo and ringing effects. Slow roll-off filters show
moderate pass-band and stop-band performance; however group delay is
minimized.
Smooth
: Smooth mode scored highest on subjective listening tests
during development. All filters in this mode are of the minimum-phase type,
which means there is no pre-echo at all. Smooth mode filters are also designed
