The Burl BDA4M is a mastering-grade DAC with stepped attenuators and switchable output transformers specifically designed for mixing and mastering. It utilizes the latest BURL NextGen analogue technology to ensure superior fidelity and clarity. This switchable transformer-coupled 4-channel digital-to-analogue converter Daughter Card results from over 25 years of R&D experience in pro audio digital and analogue design.

Following the resounding success of the B2 BOMBER DAC and the BDA8 for the MOTHERSHIP, the BDA4M represents the pinnacle of excellence in pro audio electronics. Its design incorporates the newly developed BOPA14, an all-discrete, class-A op-amp with minimal transistors. The BOPA14 has undergone extensive listening tests, resulting in stunning clarity and definition that sets a new standard for analogue audio fidelity. If you were impressed with the original BOPA1, prepare to be blown away by the BOPA14, which delivers even tighter bass and more exceptional detail throughout the audio spectrum.

At the heart of the BDA4M lies the renowned BX5 output transformer, previously used in BURL Audio’s acclaimed B32 VANCOUVER MIX BUS. Engineers and audio enthusiasts alike have marvelled at the transformative effect of the BX5. It imparts a certain magic to the sound, elevating it to a new level of richness, depth, and size. The BX5 ensures that every element of your audio mix, from kick drums to vocals, will sound not just better but truly massive and captivating.

There has long been a tradition in audio engineering of fully digital projects through a 2-track analogue tape machine to add warmth and reduce digital harshness. With the BDA4M and its BX5 output transformer routed to a BAD8 or BAD4 with the BX1 input transformer, this process is taken to a new level of excellence. The combination eliminates tape hiss while providing higher dynamic range and more headroom, producing an exceptionally transparent and pleasing sound.

On the digital side, the BDA4M introduces some exciting new features. It offers a switchable DAC filter, allowing users to customize the tone from the classic BURL sound to a more aggressive and forward mid-range. This flexibility empowers audio professionals to shape their sound precisely according to their artistic vision. Additionally, the BDA4M incorporates AVID delay matching, enabling perfect synchronization of output delays when using AVID IO hardware inserts. This is a crucial capability for maintaining precise timing and phase alignment in complex audio setups.

Whether you are already a proud owner of a B80 MOTHERSHIP or considering the acquisition of a new B16 or B80 MOTHERSHIP, the BDA4M is an outstanding addition to your audio arsenal. It complements the super clear BDA8, and even a single BDA4M integration with your MOTHERSHIP will significantly improve audio quality. With its bold and robust performance, the Burl BDA4M embodies audio engineering excellence – a testament to the "BURLY" standard of unparalleled audio quality.
