Manual
The B173 is largely based on the classic design of a Neve 1073. We originally set out
to create a direct clone, but ultimately decided to pursue our own unique design that
combined both modern and vintage characteristics in a portable, compact enclosure.
transformers, stepped gain, an output attenuator, phantom power, and switchable phase.
It features up to 80dB of gain, is housed in a 1U, 1/2 rack chassis, and has a high-impedance
DI input that will work with anything from guitars to keyboards.
Our aim was to combine the creamy fullness of a Neve 1073 with the polished clarity found
in many expensive, modern preamps. The result is a well-balanced, smooth-sounding
preamp with low noise and plenty of gain.
