Burl B4 Mic Pre Card for Mothership

4-channel mic/line input ADC Mothership daughter card featuring BX6 input transformers, Burl's NextGen BOPA14 OP-AMP, and an all Class A, discrete signal path

The Burl Audio B4 is a four-channel microphone preamp daughter card for the B80 and B16 Mothership. Featuring four mic/line inputs, pristine-sounding analog to digital conversion, and an all Class A discrete signal path, the B4 is a must-have daughter card for any Mothership owner.

BX6 Input Transformers

Featuring the newly designed BX6 input transformer, the B4 mic pre is capable of dialing in a wide range of sounds. At low levels, the B4 delivers a crisp, clean sound akin to high-end digital preamps. Crank up the gain to drive the BX6 input transformers for loads of classic analog saturation.

BOPA14 Op-Amp

The B4 mic pre is equipped with Burl’s NextGen BOPA14 op-amp—the same ultra-linear converters used in the best-selling BAD8 analog-to-digital converter daughter card. Combined with the colorful BX6 analog input transformer, this flexible preamp is perfect for any project—from clean modern productions to classic rock, soul, R&B and more.
