Four Channels of D/A for Your Mothership

Get to know them!

Load a BDA4 D/A converter module into Burl Audio's B80 Mothership system, and enjoy four channels of ultra-high-quality analog audio output. Its accurate conversion circuitry flawlessly re-creates chest-thumping lows, breathtaking highs, and magnificently detailed stereo images. But the key to the BDA4 is Burl Audio's extreme focus on the analog signal path, which rivals the topography of any high-end piece of analog gear. Benefit from switchable D/A filters for variable tone and switchable delay settings to match AVID converters. So whether you're sending signal to your favorite outboard gear or to your studio monitors, the sound you get from the Burl Audio BDA4 is second to none.

This is a 4-channel digital-to-analog conversion module for a Burl Audio B80 Mothership system. It must be installed in a B80 Mothership chassis to function.

Audiophile-quality analog signal path

Many professional D/A converters fall short when it comes to the analog side of the process, providing you with excellent digital accuracy but unnaturally sterile sound. That's what inspired Burl Audio to develop the unique signal path in the BDA4. Like the B32 Vancouver mix bus, it includes a BX5 nickel core output transformer on every channel. You also get a proprietary BOPA14 op-amp and a capacitor-less Class A analog signal path with discrete transistors. The BDA4 supplies you with both clarity and the extremely high headroom required to respond smoothly to highly dynamic audio. When we witnessed the BDA4 in action here at Sweetwater, we heard "natural" not "digital."

Burl Audio B80 Mothership — a new way to configure your studio

The Burl Audio B80 Mothership represents an innovative way of approaching digital conversion. You can create a custom, modular converter system with up to 80 channels of D/A conversion or up to 40 channels of A/D conversion! The B80 Mothership is a 4U, 10-slot empty chassis into which you can install any combination of Burl A/D and D/A converter cards. A 1U power supply is included, providing ample power for the high-headroom, low-noise converters. Burl Audio converters are renowned for their tape-machine-like response to signal level, giving you control over your signal's tone through gain staging. Burl digital converters give you a world-class analog front end with amazingly deep and detailed conversion, and the B80 Mothership makes it possible.
