Top of this Audio subpage will be an entry for the SD101 Synclavier DAC.
This is the inbuilt DAC (digital to audio conversion unit). This DAC feeds
balanced and unbalanced (often referred to as single-ended) outputs, as well as
headphones.
The inbuilt DAC circuitry has been designed for studio use. It’s been locked to
50kHz to take full advantage of the Synclavier II DSP (Digital Signal Processing)
synth engine, which was optimized around the 50kHz sampling rate of the
original “poly-sampling” system and to give accurate reproduction of many of
the included NED samples that were recorded at 50kHz.
The SD101 is a high-resolution 24-bit stereo DAC circuit with extremely low
noise and negligible jitter designed for studio use. Research into human hearing
shows humans with the best hearing can discern a maximum of 21 bit of
dynamic range (2097152 levels of amplitude). A CD is mastered for 16-bit digital,
so why go to 24-bit?
This level of redundancy is good. Regen can be used in different settings with
different gain-staging and can play many voices (up to 98) simultaneously. With
this level of performance built-in, Regen is never going to be the weakest link in
your audio chain.
Having lots of digital levels (bits) is worthless if that resolution is lost later in
the analogue circuitry. The balanced outputs have been measured to perform at
130db above the noise floor, exceeding studio requirements for useable dynamic
range. The unbalanced outputs were measured at 110dB.
As good as the built-in DAC is, there may be times when you want to use
your own converters and bypass it. Perhaps you want to plug into a studio’s
converters, or “house” sound at a venue, or use your own audio interface simply
