D-3000 is used to playback DSD files, the DSD LED indicator will illuminate, as well as the LED indicator
for one or the other of the 176/192 or 352/384 sample rates, indicating the DSD rate. The 176/192
indicator means the input signal is DSD 64, and the 352/384 indicator means the input signal is DSD
128. During playback of a native DSD signal from the source, the "CONV" and "UPSAMPLE" buttons
are not used.
The button labelled "CONV" is used to implement real-time conversion to DSD. The LED indicator for
CONV illuminates when CONV is selected (this will occur even when playing a DSD file and CONV is
selected; however, in that case, no conversion is occurring). You may notice that gain in the DSD
conversion mode is slightly lower than that in the source input sample rate and upsampling modes.
This is normal and is compensated for by adjusting your volume control.
Please note that the DSD indicator light has two meanings; it indicates either that the D-3000 is playing
a native DSD signal from the source, OR that conversion to DSD has been selected by the user.
PCM Playback and UPSAMPLE
When the D-3000 is playing a PCM signal from source, the appropriate LED indicator for the source
sample rate will illuminate.
Please note that some high sample rate PCM signals may carry background white noise in addition to
the audio; this is because many freely distributed high resolution PCM files are generated using either
a software or hardware up-sampler that is not of sufficiently high quality. It is recommended that, if
possible, the source software or device is used to down-sample such signals to improve the sound
quality.
Please also note that while the D-3000 filters incoming low quality SPDIF interface signals, some
source devices in the market do not meet S/PDIF standard or are otherwise of insufficient quality and
can be noisy.
The button labelled "UPSAMPLE" is used to select the desired up-sampling rate (See Figure 1).
Repeated presses of the UPSAMPLE button move the unit through the available up-sampling rates as
indicated on the front panel.
NOTE: The user cannot control the up-sample rate for conversion to DSD; the D-3000's conversion to
DSD and PCM "UPSAMPLE" functions are discrete processes.
Drivers are not required for Mac/Linux operating systems. The Thesycon driver is compatible for
Windows applications and is available on-line. It is currently planned to have a Windows compatible
driver that will specifically recognize the D-3000 DAC available for download from the Audiomentors
and Allnic Audio websites.
Of course, BE CAREFUL about differences in gain between your sources. Generally, disc players and
tuners will have greater gain than phono-stages. That means the volume setting for listening to your
turntable might be too high for listening to CDs.
