INTRODUCTION
First of all, thank you for purchasing HEDD Quantum. This updated version of
HEDD will open up a whole new world of definition and clarity in your workflow.
HEDD, acronym for Harmonically Enhanced Digital Device, has been
engineered to provide musically pleasing sound with the capability of
generating tube/analog sounds within the digital domain.
The HEDD QUANTUM has a new clocking crystal. It’s Crane Song’s 5th
generation design, like the ones used in Avocet IIA and Solaris and has less
then 1pS jitter. This results in extremely accurate imaging, a very open 3d
sound and detailed transient response.
Jitter is one of those “black art”, hard to explain phenomena. The artefacts
caused by jitter are blurred, harsh and unfocussed sound. It also results in a
loss of image stability, depth and space.
Jitter, basically a time deviation in the clock timing, is caused by many factors.
The main culprit being the frequency of the clock varying during the conversion
process.
The newly developed crystal clock within the HEDD QUANTUM has reduced this
jitter to the ,currently, lowest possible value, resulting in a well defined low end
and clear top end. This will allow you to judge your work more accurately and
will provide you with a much stabler image making panning, EQing a lot faster
and truer.
It can take a little time to get to grips with these subtle but extremely
important issues. It’ll take a bit of ear training. To get you started, head on
over to the Cranesong Jitter Page. http://www.cranesong.com/jitter_1.html
In addition to the new AD, DA, Clocking, I/O (Toslink Optical has been added)
and extra WC outputs, HEDD QUANTUM still comes equipped with the same
great DSP emulation of Triode, Pentode tubes and Tape emulation from the
original model.
The operational modes now allow the DAC and the ADC to be used
simultaneously and at different sample rates. When set to the DIGI setting,
