Black Lion Audio B173 500-Series Microphone Preamp

The B173 is one of the most “bang for your buck” preamps in existence, and is now available in the 500 series format. The B173 500 not only delivers the beefy lows, buttery mids, and polished highs of a classic 1073 preamp, but does so at a fraction of the price!

The preamp and line amp circuitry found in the B173 500 is identical to the original B173. Not a single component or design feature was compromised while converting it to a smaller package. As a result, the circuit boards are jam packed with all sorts of delicious components, including a brawny Cinemag input transformer!

The power supply is the backbone of any preamp design, and can make a huge impact on the overall sound and performance of the preamp. The +24V rail needed to power the B173 500 is painstakingly converted from the +/- 16V rails of a 500 series rack using a custom DC-DC converter circuit specially designed to keep any unwanted noise or modulations out of the signal path. Complete isolation is then achieved through the use of inductors, ferrite beads, decoupling capacitors, power regulation, and a custom enclosure surrounding the entire circuit.

The B173 500’s “Class A”, discrete circuitry combined with high-end components provide a fresh approach to a classic sound that won’t disappoint. Thanks for your purchase and continued support of Black Lion Audio!

Black Lion Audio AGB Compressor October 11, 2011
Reviewer: Garnett H Bennett from Antonito, CO United States  
AFTER A COUPLE OF WEEKS USING THE BLA COMP /LIM AND THE EQ I REALY LIKE THEM SINGULAR OR COMBINED . IT TOOK A FEW MINUTES TO LEARN THE AGB BUT AFTER THAT I USED IT FOR CUTTING TRACKS AND COMBINED IT FOR A MASTERING SET UP WITH THE AM/CH  EQ. THE COM/LIM REMINDS ME OF LA2/3'S BECAUSE ITS SMOOTH ATTITUDE BUT YOU CAN DO A WHOLE LOT OF OTHER THINGS THAN A LEVELING AMP WITH IT . THE LIMITER SECTION IS FAST AND TRACKS THE SIGNAL THATS NEEDED. I WISH I COULD HAVE HAD THAT AS A TOOL TO PREVENT HI FREQ SPLATTER BACK IN MY DISC CUTTING DAYS AT COLUMBIA RECORDS .  THE EQ IS NICE TO WORK WITH BECAUSE YOU CAN DIAL IN ANY AMOUNT OF EQ AT ANY GIVING FREQ  AND CATCH THOSE IN BETWEEN SWEET SPOTS . IN CONCLUSION BOTH UNITS DISPLAY A VERY HI FI SHEEN TO THE CHAIN OF AUDIO SOLO  OR LINKED UP . IM NOT GOING TO USE THE SORRY  EXCUSE AND SAY "GREAT  IN ITS PRICE RANGE" IN SHORT I DONT THINK YOU NEED TO SPEND 10K TO SET UP A MASTERING RIG,  I LOVE WHAT I HEAR AT 2K ".... KEEP IT IN YOUR SPEAKER"... REGARDS
