Forget everything you know about DACs. Yggdrasil's unique True Multibit architecture delivers 21 bits of resolution with no approximations or guessing. True Multibit eschews delta-sigma D/As and their embedded digital filters, combining medical-grade multibit D/A converters with a unique time- and frequency-domain optimized digital filter that preserves the original samples. 

Unique Digital Filter Preserves Original Samples
Most DACs simply use the stock digital filters embedded in their D/A converters. But even the most sophisticated ones, using their own digital filter algorithms, don’t have what Yggdrasil has—a time- and frequency-domain optimized digital filter with a true closed-form solution. This means it retains the original samples, performing a true interpolation. This digital filter gives you the best of both NOS (all original samples retained) and upsampling (easier filtering of out-of-band noise) designs.

Mission-Critical D/A Tech, Discrete Class A Analog 2 Output
For MRI diagnoses, doctors don’t rely on the guesswork of “24 bit” or “32 bit” delta-sigma D/A converters. Instead, they choose the bit-perfect imaging of precision multibit D/A converters, like the blindingly expensive Analog Devices AD5791. We chose this same critical technology for Yggdrasil. Now in Analog 2 form (shipping since late 2017), we’ve combined the output of four of these DACs with DC-coupled, low-noise, Class A JFET buffers and summers with high current output capability to drive long cable runs and low-impedance line inputs, such as 600 ohm professional gear.

USB, Elevated: Unison USB™, Plus Adapticlock Advanced Input Optimization
Yggdrasil now includes Unison USB, our own USB input based on a general-purpose PIC32 microprocessor, using precision local clocks and complete electromagnetic and electrostatic isolation. No more off-the-shelf USB for us—this unique, UAC2-compliant input provides the highest performance and lowest power draw of any USB input we’ve offered to date. Yggdrasil accepts up to 5 digital inputs and carefully manages them with our Adapticlock™ clock regeneration system. Adapticlock is the most sophisticated clock management system in the world. It assesses the quality of all inputs, measures their incoming center frequency and jitter, and automatically routes the input to the best clock regeneration system. 

Designed and Built in California

By “designed and built in California" this is what we mean: the vast majority of the total production cost of Yggdrasil—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. Our transformers are also made in California. You get the picture.
