THE MUTE BUTTON
Output signal is fully cut by means of the “MUTE“ button. When
engaged, the red “MUTE ON / ERROR“ LED will light up.
RESAMPLING
Resampling is a mighty feature for the transformation/restoration of
jittered signals into high-quality signals. As well, the signal quality of
44.1 or 48 kHz sources can be improved by converting them to a higher
rate. This also complies to the USB input which often suffers from jitter
caused by improper treated computer outputs. With the aid of resamp-
ling process nearly all jitter (and not only specific ones) is removed from
the USB data stream without using “asynchronous USB mode” which
often is the cause for the next issues. We know that computers are
solving problems which haven’t been existing before.
This isn't mystery at all, but a feature offered by so-called sample rate
converters - available since the nineties of the past century.
While early sample rate converters could provide conversion ratios of
1:2 to 2:1 (at 100dB dynamic range) only, ratios of 1:16 to 16:1 at 140
dB dynamic range are feasible today.
In principle, the digital data stream is asynchronously disassembled by a
DSP specially developed for this purpose, and can be recombined at
virtually any sample rate desired.
By means of this process, all potential jitter vanishes almost completely
and - due to the higher sampling rate - the analog filters after the
converter stage can follow a much more straightforward and "musical"
design. Furthermore, all digital input signals will be completed to 24 bit
signals what is valuable in conjunction with the digital volume control.
THE RESAMPLING BUTTON
By pressing the “RESAMPLING“ button, the modes OFF > x1 > x2 > x4
> BEST can be stepped through in clockwise order.
