B173 500 Mic Pre

$599.00

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!

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 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!
