Black Lion Audio White Sparrow MK2 ADC

There is an obvious need for affordable, yet good-quality converters within the professional and project studio world. Certainly there are great two-channel systems available, but they are prohibitively expensive. Those that are within reach of the project studio’s budget usually suffer from the poor sonic qualities that plague mass-produced studio equipment. We have made it our mission to develop superior-quality, boutique audio equipment but at very “un-boutique,” affordable prices.

Black Lion Audio proudly introduces our brand new, completely redesigned 2-channel analog-to-digital converter, the Sparrow mk2 ADC!

 

The Sparrow mk2 is housed in a 1U 1/2 rack chassis, featuring XLR and ¼" balanced inputs, LED metering, BNC word clock I/O, AES output, coax & optical S/PDIF output, and user selectable signal calibration accommodating nominal input signal levels from +11dBu down to -10dBV. It features sampling rates from 44.1kHz -192kHz, with a clocking architecture that features low jitter and wide Q third harmonic crystal oscillators, and because of the quality of the clock multiplier and PLL recovery stages, performance will not degrade should the converter be synched to a lower quality word clock reference.

 

The A/D conversion process is a tricky beast to tame. Because conversion requires so much current movement, there are plenty of places for unwanted noise to be created, both within the signal chain and in the power supply. This unwanted noise manifests itself within the audio signal as a grainy distortion, and often resides in the upper frequencies.

As we began to research and test approaches to converter design, we discovered a unique way to reduce this unwanted noise and distortion, one that's not only inexpensive to implement but also works better than traditional approaches. We coupled this proprietary converter circuit to a high-speed, high-headroom analog stage that can capture the smallest nuances and micro-dynamics. The result is unparalleled: an inexpensive two-channel A/D converter that not only has an enormous sound with pinpoint imaging, but also has the smooth, wide open sonic quality of expensive high end systems and a wonderfully rich midrange.

Our Sparrow mk2 (named as an homage to French singer Edith Piaf) features 4 input stage trim presets and a single ultra-low distortion amplifier before the converter for simplicity and purity of signal path. Power supply filtration is designed around latest-generation organic semiconductor capacitance instead of a traditional electrolytic-based method, ensuring low power supply noise. This is an A/D that can easily go head to head with the big boys; once you use the Sparrow Micro Series A/D converter, your standards will be forever changed!

 

THE SPARROW MK2 WHITE

Okay, sometimes it's fun to show what your design team is capable of creating. The White version of the Sparrow mk2 (white faceplate) represents a portion of our research into delta sigma conversion and clocking architecture. What sets it apart from the rest of the pack? For one thing, instead of using one converter for stereo conversion, it employs TWO converters in a parallel-balanced circuit to drastically boost converter dynamic range. Add to this our unique approach to converter configuration, our 220/270SP master clock with wide Q third harmonic crystal oscillators, advanced PLL recovery, and a low noise analog path, and all of these elements together will yield the richest, clearest and fattest sounding A/D converter to ever have set foot in your recording studio. The Sparrow mk2 WHITE is $1999 and outperforms the FM192, making it among the best two-channel A/D converters available in the pro audio market today, period.

 

"Finally a converter that sounds EXACTLY like what I hear coming out of my SSL.  The White Sparrow mk2 is the cleanest way to go from A to D"  

--Tom Lord Alge 

 

Keep In Mind...

In addition to its incredible cost-performance ratio, what makes the Sparrow mk2 so unique is that the design is modular and completely upgradable. The converter circuitry and the analog circuitry are housed on separate, fully interchangeable cards. This means both the analog and converter path can be altered or upgraded by simply changing out circuit boards.

So, if you wish to upgrade from the basic Sparrow mk2 BLACK to the Sparrow mk2 RED, or from the red version to the white Sparrow, this can be accommodated very easily & affordably!
