Burl B80 Mothership – MADI




Simply put, the B80 MOTHERSHIP has redefined digital recording. For anyone who has felt that digital recording has been lacking soul, warmth, and musicality, the B80 MOTHERSHIP is the answer. Building on the technology of the two-channel B2 BOMBERS, the B80 MOTHERSHIP was forged from Burl Audio’s deep dedication to analog class-A circuitry. The result is not only heard but also felt. The MOTHERSHIP stands out from every other interface on the market not because it is colored, but because it does not sterilize the source.

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 4 and 8 channel AD/DA cards, all with class-A, discrete electronics without any integrated circuits or capacitors in the signal path. The B80 MOTHERSHIP is the result of over 30 years of tireless research and development. The no-compromise, no BS design strategy is immediately apparent in the build quality.

Recording an entire band and playing back entirely through the B80 MOTHERSHIP is truly a beautiful experience. With a completely configurable AD/DA interface, a converter for any situation can be realized. If you’re a mix engineer, load up the B80 with 8 BDA8 cards and a BDA4M for 68 channels of mind-blowing fidelity. If you track live, 8 BAD8 cards will give you 64 line-level inputs, or 10 B4 Mic Pres loaded up in a single B80 Chassis will give you 40 channels of Mic Pre AND A/D conversion. Rocking!

Digital interconnect is also completely configurable and controlled by a swappable motherboard. Burl Audio offers four digital motherboards for the B80; the BMB1 (Digi-link), BMB2 (MADI), BMB3 (Dante) and BMB4 (SoundGrid).

The BMB1 comes standard with two DigiLink connectors for direct hookup to Pro Tools. Burl Audio does away with the expansion port, making both ports primary. 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.

The BMB3 features two Ethernet ports for use with DANTE enabled DAWs and any DANTE enabled device, such as a digital mixing console. With two DANTE ports, 64in/64out at 44.1k, 48k, 88.2k, 96k, and 32in/32out at 176.4k, and 192k are supported.

The BMB4 features an Ethernet port for 64 IO channels of Waves SoundGrid connectivity. SoundGrid is an Audio-over-Ethernet networking and processing technology developed by Waves. With 6 BAD8s and 4 BDA8s, a 48×32 IO can be achieved. With 2 BAD8s and 8 BDA8s, a 16×64 IO can be achieved.

No more cascading units with multiple word clocks. All channels can run off of one internal master clock. Goodbye word clock generator! Of course, if you do need more channels, multiple B80 chassis 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 B80 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. Master clock travels directly to each Daughter Card eliminating the need for individual PLLs. Configuring a B80 MOTHERSHIP is literally a snap. Slide the Daughter Card into the card guide, snap it into the BURL BACKBONE, turn the thumbscrews, and you’re there.

Powering a unit like the B80 MOTHERSHIP takes some juice, so Burl Audio designed the BP300 to drive the 80 channels of class-A analog circuitry. With a 300-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 any music, live sound, broadcast or film recording environment, 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.
