  • Page 3 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.
  • Page 4 AKM 32-bit components, coupled with proprietary analog filtering and clocking. Coupled with ultra low jitter, HEDD QUANTUM gives any user who works digitally the ability to sound more analog. The HEDD QUANTUM controls allow the user to select input source, sample rate and continuously variable tape, triode and pentode sounds.
  • Page 5 SAMPLE RATE SELECT Here are a few items to be aware of when you boot up the HEDD QUANTUM. The WC LED will flash 14 times during boot up and at the end of the 14 times there may be some random lights on the meter for around a second.

  • Page 7 When a valid word clock is applied and WC is selected the red light next to the switch will light to indicate lock. If lock is lost, HEDD Quantum will default to 44.1kHz and the light will be off. Whenever the sample rate is changed, the convertor is re-calibrated.

    Digital in - Digital out modes. The dither is enabled by selecting the process in the 16 or 20 bit groupings. THE PROCESS HEDD QUANTUM generates harmonically related information. The processing was developed by studiously analysing the harmonic distortion and characteristics found in classic and revered audio equipment and a lot of listening! The harmonic process runs 24-bit internally.
  • Page 9 5 and up range it is easy to go too far but, don’t forget, it could be a cool thing. The HEDD QUANTUM processing can be extremely subtle or very drastic. It depends on how you use it. Getting to grips with the diversity of the processes will take a little ear training.
  • Page 10 DITHERING The dither process in HEDD QUANTUM is proprietary to Crane Song. It is an analog generated source that has been filtered to a spectrum where the ear is least sensitive. We believe that this process sounds better than other systems and is less likely to cause noise problems as compared to other dither sources.
