Burl Audio Modular Converter Chassis w/ BP250 Power Supply
Additional Photos:
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 MOTHERSHIP is the answer. Building on the technology of the two-channel B2 BOMBERS, the MOTHERSHIP was forged from BURL AUDIOS deep dedication to analog class-A circuitry. The result is not only heard, it is 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 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 youre 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.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
