Burl Audio B16 MOTHERSHIP with BAD4M & BDA4M: Compact Powerhouse for Mastering-Grade Conversion

The Burl Audio B16 MOTHERSHIP is a 2U, 16-channel modular AD/DA converter built to deliver flagship-level performance in a portable, flexible format. Featuring the BMB1 Digilink motherboard, it integrates seamlessly with Pro Tools systems and utilizes the same world-class Class A analog circuitry found in the legendary B80 MOTHERSHIP.

Designed to suit a range of professional workflows, the B16 can be configured in multiple ways: from a 4-in/8-out tracking rig to a 16-output portable mix system, or even an 8-channel AES I/O setup. With full compatibility across Burl’s acclaimed AD/DA cards, the B16 offers unmatched sonic versatility in a compact footprint.

At the core of this system are two cutting-edge conversion modules: the BAD4M and BDA4M.

BAD4M – 4-Channel Mastering-Grade AD Converter

The BAD4M is a 4-channel analog-to-digital converter designed for the most demanding mixing and mastering environments. Engineered with stepped attenuators and switchable input transformers, the BAD4M allows users to tailor their sound with precision. It features Burl’s NextGen analog technology and gives engineers a choice between the newly refined BOPA14 all-discrete op-amp and the BX1 transformer-coupled path, delivering two distinct sonic signatures: either the warmth and depth reminiscent of the BAD8 or the pristine clarity of a transformerless signal path.

A switchable ADC filter lets users toggle between the classic BURL character and a more midrange-forward, assertive tone. Additionally, AVID delay matching ensures perfect sync when integrating hardware inserts with AVID I/O, preserving critical timing and phase integrity.

BDA4M – 4-Channel Mastering-Grade DA Converter

The BDA4M is a 4-channel digital-to-analog converter built for mastering precision, featuring stepped attenuators, switchable output transformers, and Burl’s best-in-class NextGen analog technology. Drawing from over 25 years of R&D, the BDA4M builds on the legacy of the B2 BOMBER DAC and BDA8 to deliver stunning detail, clarity, and depth.

At the heart of the BDA4M lies the groundbreaking BOPA14 op-amp, offering tighter bass and enhanced imaging, and the revered BX5 output transformer, known for its ability to add dimension, warmth, and power to any mix. This combination brings a magical analog depth to fully digital productions—enhancing dynamics and headroom without the drawbacks of tape, such as hiss or saturation.

A switchable DAC filter gives users tonal flexibility—from smooth, vintage coloration to a more aggressive, modern sound. Like the BAD4M, the BDA4M includes AVID delay matching for seamless hardware insert integration.

Unrivaled Sonic Performance in a Compact Format

Together, the B16 MOTHERSHIP, BAD4M, and BDA4M create a formidable hub for professional audio production. Whether you're tracking, mixing, or mastering, the system delivers a level of analog richness and digital precision that bridges the gap between classic warmth and modern transparency.

Whether you're expanding an existing B80 setup or looking for a high-performance compact solution, the B16 loaded with BAD4M and BDA4M modules provides an elite-grade conversion experience worthy of the "BURLY" reputation.
