NSEQ-4

Discrete Solid State Two Channel Parametric EQ

Full Timbral Control, Total Signal Integrity

  • World's first (and only) all-discrete, true differential Class-A input buffer/amplifier.
  • Selectable balanced or unbalanced input.
  • Greatly improved 3rd generation FSA-03 all-discrete EQ amplifier
  • Improved output stage, no muting required (as with Twin Topology)
  • True hard-wire bypass when EQ not selected
  • Upgraded power supply leading to improved sonic performance
  • Fully parametric stereo EQ with unprecedented sonic purity and integrity
  • All discrete J-FET solid state signal path
  • Minimalist design: only one active stage in the audio path
  • Identical EQ stage used in Library of Congress archiving path
  • Four EQ bands: 20 Hz to 20 kHz center frequency, 0.4 to 4.0 Q
  • Extremely low noise: -106 dBu
  • Constructed for demanding professional applications
  • Ultra-Premium components throughout
  • Gold relays, connectors, switches,
  • Silver Teflon power wiring
  • Mogami Neglex OFC audio wiring

Options:

  • Detented, loggable controls
  • NSEQ-2 can be converted to an NSEQ-4
