From Millennia Media
Full Timbral Control, Total Signal Integrity
Thousands upon thousands of professional engineers use the discrete Class A NSEQ parametric EQ's 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 micamps).
We've lost count of the number of engineers who've told us that their "favorite thing about the NSEQ is its incredibly musical top end." It may not be an exaggeration to say that most clients use the NSEQ to breathe top-end musical life into their tracks. The one comment we hear continually: "the 21kHz top end boost sounds like music, not like EQ."
So we thought it was time to create a new product that focused exclusively on the NSEQ's top-end. We call it the NSEQ-HF, and it's ready now for your 500-rack, at an attractive price point. The NSEQ-HF employs the identical circuitry found in the NSEQ-4: our renowned FSA-03 Class A all-discrete J-FET amplifier and our DSA-01 Class A all-discrete J-FET true-differential line receiver. Both amplifiers use Toshiba 2SJ74 and 2SK170 discrete J-FETs exclusively, considered the holy grail of pure Class A discrete audio design topology.
Features:
- World's first (and only) all-discrete, true differential Class-A JFET input buffer/amplifier
- Selectable balanced or unbalanced input
- Transformerless signal path
- True hard-wire bypass when EQ not selected
- 100% discrete Class A signal path using ultra-rare Toshiba J74 and K170 J-FETs
- Minimalist design: only one active stage in the audio path (Dove Topology)
- Extremely low noise: -106 dBu
- Constructed for demanding professional applications
- Ultra-Premium components throughout
- Gold mil-spec Grayhill rotary freq-select switch
- Lovingly hand-crafted in Northern California
