B173 Mic Pre


Introducing Black Lion Audio’s own Neve 1073-style microphone preamp, the B173! Don’t let the price tag fool you. This is not only a serious contender for the most “bang for your buck” preamp in existence, but sonically stands on its own at any price point. Our goal was to capture the essence of the original Neve 1073 at a price anyone can afford, and we’re proud to say that we’ve accomplished our goal!  Tape Op gave it a run, and couldn’t agree more.  Give the B173 a try and prepare to be blown away!

Additional 1 year warranty (3 years total)

We offer an additional one-year warranty on top of the standard two-year warranty on defects in materials and workmanship for this item from the date of purchase. See Disclaimer & Warranty tab for more info.

Product Description

The B173 is Black Lion Audio’s homage to the highly revered Neve 1073 mic pre. The B173 is a single channel mic pre-amp with input and output transformers, stepped gain, output level control, phantom power, and phase. It features a DI, 80dB of gain, and is housed in a 1U, 1/2 rack chassis.

“The sound was as creamy and full as would be expected from a device based on a 1073… the B173 has ‘that sound’!”

– Tape Op Magazine (full review here)


“At one point, I just wanted to run everything though it,” commented the electronic musician, “it just gave the sterile virtual synth sounds that much needed analog cellulite that’s desperately missing.”

“Black Lion Audio set out to ‘capture the essence of the original Neve 1073’… I think that they’ve succeeded admirably…”

“Just wanted to thank you guys for a great product, i.e. the Black Lion B173! This half-rack monster is a straight up beast! It arrived last week and I used it on my first session today. This was a return client who is very familiar with my current mic-pre .i.e.Groove Tubes Vipre and a Peluso P12 microphone. I tried the B173 44db of gain and Output level set to 11 o’clock with the P12 and we all were blown away. I’ll pass this info along to my colleagues and my 4700 FB friends!”

– Randy Seale, Reflective Productions And Recording


“I used the B173 on the bass, lead guitar, kick and snare. I also hit it on the vocal after the Avalon 737SP pre. I always hit the Distressor for compression after the B173. It adds a nice thickness to things that need it. The Cinemag and Edcor really work out well together in that little box. Thanks for making great gear at an affordable price point.”

William Smith


“It sounds amazing. Best mic pre I own including AEA and UA units.”
