HEDD, short for harmonically enhanced digital device, is a technological breakthrough in signal processing. HEDD is engineered to be musically transparent while providing the capability of generating tube/analog sounds in the digital domain.

HEDD gives any user who works with digital the ability to sound less digital and more analog.

Applications include: CD preparation, work station input and output, DAT machine A/D and D/A convertor replacement and effects generation (warming or changing sounds in the digital domain). HEDD 192 can be used in tracking, mixing or mastering.

The HEDD signal processor has the following features:

  • High Quality 24 Bit A/D and D/A Convertors
  • 24 Bit Processing
  • Adjustable Triode, Pentode and Tape sounds
  • Digital I/O, AES and S/PDIF
  • External WC Sync Input and Output
  • Upgradable to 192K sample rates

The front panel controls allow the user to select input source, sample rate, and continuosly variable triode and pentode sounds. The HEDD can operate as an effects device or as separate A/D amd D/A convertor with the sound enhancement process applied to either the A/D or D/A convertor.

HEDD has transformerless balanced analog inputs and outputs, transformer isolated digital inputs and outputs, and uses separate power transformers and supplies for the analog and digital sections. The unit is 1 rack space tall and operates from 115V or 230V mains.
