NSEQ-2 Twin Topology Two Channel Parametric EQ
This product has an estimated 3-5 day shipment processing time.
Full Timbral Control, Total Signal Integrity
- Two paths to perfection with Twin Topology™
- Fully parametric stereo EQ with unprecedented sonic purity and integrity
- All triode 300 V vacuum tube signal path or all discrete J-FET solid state signal path
- Both topologies are entirely transformerless high voltage pure Class A
- Minimalist design: only one active stage in the audio 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, tube sockets
- Silver Teflon power wiring, Mogami Neglex OFC audio wiring
- Lovingly hand-crafted in Northern California
Options
- Differentially balanced inputs
- NSEQ-2 can be converted to an NSEQ-4
