Big Iron Passive Transformer Based Stereo Processor

Big Iron is a passive stereo transformer processor built to add weight, depth, and subtle harmonic character without adding active circuitry. At its core is a matched pair of Jensen JT-11-FLCF transformers, giving mixes, buses, and individual tracks a polished analog solidity while preserving clarity and transient detail. Designed and built by Analog Prairie.

True North Passive Transformer Based Stereo Processor

True North is a passive stereo transformer processor built around a pair of Hammond 1140-LU-B transformers. It brings a more textured, vintage-leaning character to mixes, buses, and individual tracks, adding weight and subtle harmonic color while keeping the signal path completely passive. Designed and built by Analog Prairie.
