Description
Pushing the boundaries once again, the B80 MOTHERSHIP AD/DA converter has up to 80 analog channel capability. Using a card based system, and a heavy duty 4U chassis, the B80 MOTHERSHIP employs 10 card slots with 2, 4 and 8 channel AD/DA cards, all with the B2 quality signal path.
Every ADC channel uses a proprietary BX1 transformer and every DAC channel has the latest BURL AUDIO discrete op-amp, BOPA2. For many who have already embraced the B2 BOMBER, this is a dream come true. Recording an entire band and playing back through 24 channels of Burl AD/DA at a time is a truly beautiful experience. With a completely configurable AD/DA, a converter for any situation can be realized. If you just mix, load up the B80 with 8 BDA8 cards for 64 channels of mind blowing fidelity. If you track live, 6 BAD4 cards will give you 24 B2 quality inputs, and 4 BDA8 cards gives you 32 channels of outputs. Rocking!
Digital interconnect is also completely configurable, and controlled by a swappable motherboard. Burl Audio offers two digital motherboards, the BMB1 (Digi-link) and BMB2 (MADI). The BMB1 comes standard with two DigiLink connectors for direct hookup to Pro Tools. BURL AUDIO does away with the expansion port, making both primary ports. That means you can play 64 DAC channels straight out of Pro Tools with one unit!
The BMB2 features two optical MADI ports for use with ASIO or CORE AUDIO PCIe MADI cards. With two optical ports, 64in/64out at 44.1k, 48k, 88.2k, 96k, and 32in/32out at 176.4k, and 192k are supported. No more cascading units with multiple word clocks. All channels can run off of one internal master clock. Good bye word clock generator! Of course if you do need more channels, multiple B80 units run flawlessly with tight clocking. With each BCLK card, add 9 additional word clock outputs per slot. 92 total word clock outputs are possible per MOTHERSHIP.The technology that makes this all possible is the BURL BackBone. The BURL BackBone is a high bandwidth backplane delivering incredible digital audio throughput. The BURL BackBone also delivers large amounts of power to the analog sections. Master clock travels directly to each converter eliminating the need for individual PLLs.
Digital add on cards to follow will be the BMADI and BAES. Because each card slot can handle a single MADI card, an entire MADI switch matrix can be realized in one unit.
The B80 MOTHERSHIP is the result of over 20 years of tireless research and development. The no compromise, no BS design strategy is immediately apparent in the build quality.
Configuring a B80 is literally a snap. Slide the card down its card guide, snap it in the BURL BackBone, turn the hand screws, and you’re there.
There are also plans for film and broadcast grade “Black Face” cards where channel density and price per channel are of greater concern.
Powering a unit like the MOTHERSHIP takes some juice, so we designed the BP250 to drive the 80 channels of class-A analog circuitry. With a 250 watt continuous power capability, and +/- 24 volt rails, a multi-channel AD/DA converter is finally getting the power it deserves.
The B80 MOTHERSHIP takes care of virtually any music, broadcast or film recording situation, revolutionizing pro audio as we know it. In this digital era, many yearn for the tone of records past, and analog tape is becoming a lost art. The B80 MOTHERSHIP clearly bridges this analog to digital gap.

Now with Dante
The future is now. Now you have a universal digital audio link that works with every computer and every audio device. You can access any ADC or DAC from any workstation in your studio. That is, if they have Dante.
Finally a high speed, high channel-count, low latency, long run length, digital link that is networkable. Until now digital audio routing was limited by point-to-point digital links that were either proprietary or based on standards that were written over 25 years ago and use old technology with limited run lengths.
The audio world has been waiting on a modern technology standard, and while others debated, Audinate acted and delivered. Pro audio, film and broadcast have all embraced Audinate’s Dante as the de-facto standard for audio over Ethernet.
Imagine the possibilities when all audio devices can be networked. Large facilities with multiple control rooms and studios can have easy access to each other. Imagine one control room runs out of outboard gear for a mix. No problem, route audio to the AD/DA in the next control room, utilizing its outboard gear. Need to use two studio main rooms with one control room? Easy, one DAW has total access to the other studio’s AD/DA. The band wants to monitor in the lounge? Again, that is no problem, all over standard CAT5e or CAT6 through a gigabit switch. How about simple 2 channel monitoring of a mix-down on a laptop? With Dante’s virtual sound card and an Ethernet jack, also not a problem.
Dante is what makes this all possible and now Burl Audio has embraced this technology. The B80 Mothership, the B2 Bomber ADC and the B2 Bomber DAC are now all Dante compatible.
A BMB3 with 1 Dante card can do:
- 64 ch. i/o at 44.1/48k
- 32ch. i/o at 88.2/96k
- 16ch. i/o at 176.4/192
And you can add a 2nd BKII card to your B80-BMB3 Mothership to double your Dante track counts.
Now you can run multiple B2 Bombers or a B80 Mothership from a laptop or any computer with just an Ethernet jack. Not only that, but any digital gear, including mixing consoles with Dante, can now directly interface with the B80 Mothership and the B2 Bombers.
Burl Audio prides itself on not only building the best sounding AD/DA converters but also on delivering high channel counts with only the most reliable, proven digital formats. Now with multiple Motherships and Dante, up to 128 channel IO is not a problem. And, those channels can be routed to any other DAW or device on the system.
There are many audio brands coming up with a multitude of ways to use Dante. Burl Audio can speak to them all and they all can have THE BURL SOUND.
You are only limited by your imagination. But have faith, the future rocks.
