Black Lion Audio Sparrow ADC MKII - White #0349A (Used)

Product Description

Okay, sometimes it's fun to show what your design team is capable of creating. The Black Lion Audio Sparrow ADC MKII WHITE (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 ADC MKII WHITE outperforms the FM192, making it among the best two-channel A/D converters available in the pro audio market today, period.
Black Lion's Sparrow ADC MKII is housed in a 1U 1/2 rack chassis, featuring XLR and _" 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 mid-range.
Our Sparrow ADC MKII (named as 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!
