Product Description
The Interphase Audio NDUCR is a 2-channel 19" rack-mount unit with 4 inductive EQ bands per channel. It's designed to add color to your signal, and silky smooth color that is. The NDUCER has four bands with switchable, overlapping frequencies:
- Low (Hz): 50, 80, 100, 150, 300, 600
- Low Mid (Hz): 125, 250, 500, 1K, 2K, 4K
- Hi Mid (kHz): 1.5, 3, 5, 6, 7, 8
- High (kHz): 8, 9, 10, 12, 14, 16
The inductor based circuit is considered the "holy grail" of equalizer designs. These were employed in the renowned Pultec equalizer design dating back to the late 1950s. Owing to their unique electro-mechanical properties, inductors impart a character all of their own, which is very distinct. The NDUCR uses 32 inductors spread out over the four bands with custom-wound Carnhill inductors in the low-mid and low bands, giving precise control and the inductor sound on each band.
Inductors provide a “peaking” characteristic, giving much tighter control of the frequency selected. The inductor values and components have been carefully chosen and matched to provide an extremely musical sound. Each band provides switch selection of any of six carefully selected frequencies chosen at musically pleasing intervals. Each band uses a 100mm fader - instead of a rotary pot - for cut and boost control, allowing very fine control of a maximum of plus or minus 15dB per band.
The NDUCR features Class A discrete electronics, however, this circuit is a decidedly modern design with updated techniques and components that were simply not available 60 years ago. This is definitely not a clone or copy!
