Millennia NSEQ-HF High-Frequency EQ 500 Rack Module
Give your productions a professional top-end sheen with the NSEQ-HF from Millennia, a 500-series rack featuring only the high-frequency section from the company s acclaimed NSEQ-4 full-range rack. NSEQ equalization topology is favored for a wide range of top-tier applications and used by the Library of Congress, Academy Awards broadcasts, and professional artists, including Celine Dion and Andreas Bocelli.
Give your productions a professional top-end sheen with the NSEQ-HF from Millennia, a 500-series rack featuring only the high-frequency section from the company s acclaimed NSEQ-4 full-range rack. NSEQ equalization topology is favored for a wide range of top-tier applications and used by the Library of Congress, Academy Awards broadcasts, and professional artists, including Celine Dion and Andreas Bocelli.
The unit uses an FSA-03 discrete JFET Class-A amp and a DSA-01 Class A all-discrete J-FET true-differential line receiver, and both amplifiers feature discrete audio design topology courtesy of hand-matched Toshiba 2SJ74 and 2SK170 discrete J-FETs exclusively, with no signal path ICs. If you re looking for a way to add some airy musicality to your productions and don t need a full-range EQ, the NSEQ-HF offers a cost-effective solution for owners of an API 500VPR or Lunchbox rack if you are using another brand, be sure it meets or exceeds the API specifications.
