Burl Audio BAD4M 4-Channel ADC Daughter Card
Additional Photos:
The BAD4M is the result of over 25 years of R&D experience in pro audio digital and analog design. Following on the success of the B2 BOMBER ADC and the BAD8 for the MOTHERSHIP, the BAD4M utilizes BURL Audio's NextGen Analog technology with the same BX1 transformer coupled circuit path as the BAD8 (no op-amps) and a transformerless analog front end using BOPA14. The BAD4M allows you to switch between the BAD8 style analog front end and the newly developed, BOPA14 based, transformerless analog front end.
The new BOPA14 with BURL NextGen Analog is the result of hundreds of hours of listening tests. It boasts stunning clarity and definition and raises the bar of excellence in pro audio analog electronics fidelity. The BOPA14 is an all discrete, class-A op-amp with a minimal number of transistors. This new analog design will blow your mind with tighter bass and higher definition throughout the audio spectrum.
For years, engineers have taken their fully digital projects and run them through a 2-track analog tape machine to make them sound "less digital". The BDA4M with the BX5 output transformer routed to a BAD4M with the BX1 input transformer does something very similar, but better. Using a BDA4M to BAD4M signal path will give you better performance than tape in that there is higher dynamic range, more headroom, and better frequency response with no tape hiss.
The BAD4M transformerless analog front end is perfect for situations where you want a pure capture of a mix or mastering chain where the signal is already warm and peak limited. The BOPA14 ensures a truly clear, faithful capture of the source material.
On the digital side, the BAD4M employs a couple of new features; a switchable ADC filter and AVID delay matching. Switching the ADC filter allows you to change the tone from the classic BURL sound to a more aggressive tone with a more forward mid-range. The AVID delay matching allows you to perfectly match the input delay of an AVID IO which is crucial for hardware inserts.
If you already own a B80 MOTHERSHIP or if you are buying a new B16 or B80 MOTHERSHIP, the BAD4M is awesome by itself or as a compliment to the mix and master DAC daughter card, the BDA4M. A B16 with a BAD4M and BDA4M is the ultimate 4 input, 4 output mastering solution. Adding even just one BAD4M to your MOTHERSHIP will be a big step up. The BAD4M is truly BURLY.

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.
