BURL Audio announces B4 4-channel MIC/Line input card and BDA4M mastering grade DA

AT LONG LAST… BURL Audio is proud to announce the NEW B4 4-channel MIC/LINE input daughter card for the B80 and B16 MOTHERSHIPs. The B4 boasts the new BX6 input transformer designed for true MIC/LINE input impedance. The B4 maintains a no compromise, class-A analog circuit, followed by the same ADC we use in the BAD8. Using a single B80 chassis, 40 input channels of audiophile MIC/LINE inputs can be realized. With digital control and SoundGrid or Dante, the B80 MOTHERSHIP with the B4 MIC/LINE daughter card is the ultimate studio grade stage box.

Next up, we've got the NEW BDA4M, a mastering grade DAC with stepped attenuators and switchable output transformers. Specifically designed for mixing and mastering, the BDA4M uses the latest BURL NextGen analog for superior fidelity and clarity.

The BDA4 transformer coupled, 4-channel digital-to-analog converter Daughter Card for the B80 and B16 MOTHERSHIP 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 DAC and the BDA8 for the MOTHERSHIP, the BDA4 utilizes the newly developed BOPA14 with BURL Audio’s NextGen Analog. The BOPA14 is followed by the renowned BX5 output transformer used in the B32 VANCOUVER MIX BUS.

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. If you thought the original BOPA4 sounded good, this new analog design will blow your mind with tighter bass and higher definition throughout the audio spectrum.

The BURL BX5 output transformer is the same large, BURLY beast used in BURL Audio’s renowned B32 VANCOUVER MIX BUS. Anyone who has tried B32 for the first time and engages the BX5 usually says “WHOA! That’s amazing!”. Forget about technical jargon, the BX5 transformer simply makes things sound bigger, phatter, deeper…better.

These NEW cards will be shown at NAMM this year. Stop by booth # 15823 and check out the newest BURLY additions to the BURL Audio product line.

Should BDA4M be as good as B2 DAC for dedicating 2 channels to monitoring and the other 2 for the 2 bus out? Because i was going to buy B2 dac but now i think i can hold a bit and but this

Man, no phase button is a hard pill to swallow for me. But I get it, I'm still amazed they were able to get 4 of those on 1 card!

Am I th eonly one confused on what these are? What is the B4? A preamp or a ADC? BDA4M, why would someone need stepped attenuators for the output? Am I that behind in the recording word, please help me!!!!

I’m glad someone broke the ice here.

I’m a bit confused as well.

I think the B4 is preamp and ADC as opposed to the BAD4/8 being just ADC.

I’m wondering how the BDA4 and BDA4M compare in sonics. Is the difference switchable transformer and stepped attenuator, otherwise the same?

Wondering if a BAD4M is in the works as well?

I could go for a quad slot mini orca. It would make a nice all in one interface solution.

can someone briefly, and kindly, explain to me why anyone would want a transformer on a DAC?

One reason: When sending audio created with Virtual instruments OTB for processing.

Another: you desire the sound of a console, and don’t mind the changes multiple loops through a transformer wil make. You might even desire it.

I used to use two B2's for the simple process of sending my ITB mix through. I had to sell the two units and I've missed them ever since. The musicality the transformers in the ADC added was totally worth the potential degradation of the conversion... but then again Burl is IMO the best sounding converter out there, so I never noticed any serious problems with the "victory lap".

I'm saving up for a mothership and am absolutely going to get the BDA4M- the ability to have two flavors of Burl trafo's on my mix is making me drool...

kind of baffled about these products as well. i dont really see a use for either within a functioning studio... everyone should have an attenuator and micpres. i would have much preferred a mastering card that gives super clean AD and DA (transformerless) in stereo for printing mixes. transformers on a DA who came up with that idea?

If you even get same or more clarity than B2 DAC, i would like to have an extra option, if i want i activate it and if i dont i dont, you could monitor without the BX5 and for the other one you see if your mix looks too digital or lacks balls you can press it, if not you still get superb clarity and transparency..

I asked Burl and they said "they might mantain the same clarity as B2 DAC if not more ".. .

Someone please buy the first one and compare it to B2 DAC with the BX5 dissengaged

I actually think these were built to use in a live setting with the MADI or Waves Sound Grid option, but I can absolutely see how these would work in a modern (hybrid) recording studio. Having Transformers on the outputs before they go to a live system's x-over/amps would be KILLER.

A high-end DA with switchable transformers is completely in line with the aesthetic of Burl's product line. I'm surprised by the confusion here.

Hopefully a polarity reverse is part of the B4's digital control. Especially in live sound, miswired cables will pop up from time to time.

Per their website, the B4 is described as a "4-channel MIC / LINE input ADC."

B4 Mic Pre | Burl Audio

So I don't know what else it could be - especially with phantom power buttons - other than a 4-channel pre-line-amp/ADC card. I expect it to cost quite a bit. But if it comes in under the price of a combo of 4x B1 preamps and a BAD4 card (which would be $5K street), then it will have good value. It'd better - considering there is no DI, output attenuation, phase control, or pad a la B1.

I honestly dont see who they left out all those features to add a mic/line pre? Everyone wanted the output attenutators on them from the start, why neglect that?

This is exactly what I want as well... I'd use that in conjunction with my console to print the output of the console and feed the monitor section.
