Crane Song HEDD Quantum

A/D and D/A converter featuring six word clock outputs for master clock functionality, Toslink I/O, and DSP emulation of Triode and Pentode tubes
MFR# HEDD Quantum

Product Description

The Crane Song HEDD Quantum applies sub-picosecond jitter clocking to the A/D and D/A converters to provide the purest sound possible, wide three dimensional image of your recordings, and highly detailed transient response. HEDD Quantum features the same sub-picosecond jitter clocking found in the Avocet IIA DAC. For those who use Toslink connectivity, optical in and outs have been added for a more flexible setup.

The HEDD Quantum can be used as a master clock at the same time as applying A/D D/A conversion through its six word clock outputs, which can also run at multiple sample rates. Three styles of DSP emulation are still utilized; Triode, Pentode and Tape Emulation.

Choose between two different operations modes, DIGI and ANA. In DIGI mode, the HEDD will accept the digital in from one of the three sources then send the output of all three digital inputs and analog connections simultaneously. ANA is an analog mode, which takes the input in as pure analog, then outputs all three digital and analog outputs at the same time.

Select between 16 or 20 bit fully analog dithering, the A/D D/A and ASRC chips are made with the highest quality AKM 32-bit components, all processed with proprietary analog filtering and clocking for an uncompromising final product.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
