  • Remote power supply with four-foot cable capable of four times the current needed by the preamps for optimum sound quality.

About Manufacturer

BAE are manufacturers of high end microphone preamp/equalizers faithful to vintage designs of the seventies and before. With a penchant for high quality transformers like Carnhill (St lves) and Jensen, everything is as close to the vintage philosophy as possible. Not only that but we insist everything is hand-wired/soldered using discreet electronics and not economized on a circuit board.
