Schiit Audio Bifrost

Bifrost 2/64 is a complete re-thinking of what an accessible DAC can be. With full hardware-balanced topology, balanced and single-ended outputs, remote control, Schiit’s unique True Multibit™ architecture with a time-and frequency-domain optimized digital filter, NOS mode, and our own Unison USB™ input and easy-to-upgrade Autonomy™ platform, Bifrost sets all the standards.

Top-Of-Class Hardware Balanced Design

Just like our range-topping Yggdrasil, the Bifrost 2/64 features a fully hardware balanced architecture. This means four 16-bit DACs total, with one DAC for each phase. You can expect the same stellar performance from both the XLR and RCA outputs, so Bifrost 2/64 works seamlessly with your system.

Featuring Schiit's Unique True Multibit™ — and NOS

Like all Schiit True Multibit products, Bifrost 2/64 uses completely unique D/A converters and our proprietary time- and frequency-domain optimized digital filter. In the case of Bifrost 2/64, four DAC8812 D/A converters—the same basic chip used in Yggdrasil Less is More—do the conversion, while the digital filter is implemented on an Analog Devices SHARC DSP. You can also choose non-oversampling mode (NOS) to bypass the digital filter entirely.

Unison USB™ is USB, Elevated

Bifrost 2/64 features 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—this unique, UAC2-compliant input provides the highest performance and lowest power draw of any USB input we’ve offered to date. 

Easy Upgrades with Autonomy™ Architecture

Slide-in hardware modules and a MicroSD card slot means this DAC never has to come back to Schiit for upgrades. Compare this to other DACs, even DACs costing many times more—only Bifrost 2/64 provides complete hardware and firmware upgradability. All original Bifrost 2s can be upgraded to 2/64 with a new card and firmware, available on our Upgrades page.
