Millennia NSEQ-HF
Thousands upon thousands of professional engineers use the discrete JFET Class A NSEQ parametric EQ in mastering, post-production, live sound, mixing, and tracking. It's the parametric EQ found in the acclaimed STT-1 Origin Twin Topology channel strip. It's the same EQ topology found in the world's most widely used phono archiving system, the LOC (Library of Congress, etc.). It's the EQ used by countless professional artists from Celine Dion to Andreas Bocelli. It's the EQ used on the 2-bus main mix for over a decade of Academy Awards TV orchestra broadcasts (along with 100+ channels of Millennia HV-3 mic preamps).
It may not be an exaggeration to say that most clients use the NSEQ to breathe top-end musical life into their tracks. "The 21kHz top end boost sounds like music, not like EQ."
Millennia thought it was time to create a new product that focused exclusively on the NSEQ's top end. The NSEQ-HF is ready now for your 500-rack, at an attractive price point. The NSEQ-HF employs the identical circuitry found in the NSEQ-4: the renowned FSA-03 Class A all-discrete J-FET amplifier and DSA-01 Class A all-discrete J-FET true-differential line receiver. Both amplifiers use hand-matched Toshiba 2SJ74 and 2SK170 discrete J-FETs exclusively (no signal path ICs), considered the holy grail of pure Class A discrete audio design topology.
