After testing the Interphase Audio EQ 2.2, our good friends / advisors / producers / engineers,
Werner Pensaert and Frank Duchene asked us to build a dual-channel version with just the 4-bands of Inductive EQ.
We loved the idea and who are we to refuse?
So here is the NDUCR.
The NDUCR has 2-channels of 4-bands of inductive equaliser.
* Contrary to our other EQs, the 4-bands are vertically aligned (channel one on the left, channel two on the right)
* Each band can be individually switched on / bypassed
* Large frequency select knobs give better hands-on control of selected frequency
* 100 mm level faders offer the finest control of cut and boost
(if in doubt, feel fine to pronounce NDCUR as “inducer”)
Taken from the middle section of the Ark input channels,
the NDUCR is the rackmount version of part of 2 channels of this middle input section.
The NDUCR is designed to add colour to your signal, and silky smooth colour that is.
The NDUCR features 2 of our IP211 modules, each containing a 4-band Inductive Equaliser.
But because of the redesigned layout, all faders, knobs and switches have been hard-wired.
While being more work, this allows for increased quality control.
The NDUCR is available as a 3 unit 19-inch rackmount unit, and can be ordered directly from our webstore or from your favourite pro audio dealer.
Four bands with switchable, overlapping fequencies
- Low (Hz):
50, 80, 100, 150, 300, 600
- Low Mid (Hz):
125, 250, 500, 1K, 2K, 4K
- Hi Mid (kHz):
2.5, 3, 5, 6, 7, 8
- High (kHz):
8, 9, 10, 12, 14, 16
Why faders instead of rotary controls ?
Simply, just because we like faders.
But also, in our opinion, faders give much better visual control of the level of cut or boost, so you know what’s going on at a glance.
4-band inductive EQ
Inductor based circuits are the “holy grail” of equaliser designs.
These were used for example in the much favoured Pultec equaliser design,
which dates back to the late 1950’s.
Owing to their unique electro-mechanical properties,
inductors impart a character all of their own, which is very distinctive.
Our inductive EQ uses inductors in each of the four bands
(unlike other so-called inductive EQ’s on the market),
giving precise control and the distinctive inductor sound on each band.
And yes, you’ll get a very distinctive sound, which most sound engineers love.
As a consequence of using inductors, this provides 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 potmeter - for cut and boost control,
allowing very fine control of a maximum of plus or minus 15dB per band.
The NDUCR has 2 inputs and 2 outputs, which are doubled.
Each input has a female XLR and a balanced jack connector. These connectors are paralleled, you can use either.
Outputs have male XLR and balanced jack connectors. These connectors are paralleled, you can use both at the same time.
Note: While you can use both XLR and jack outputs at the same time (for example to split the outputs and send these to multiple destinations), it is not a good idea to use both XLR and jack inputs at the same time.
Below is a short movie of the related EQ 2.2 (VU)
The Inductive EQ section on the EQ 2.2 is the same as on the NDUCR, so this movie should give you a good idea. Note however that the NDUCR features 100mm faders, allowing for much finer control of cut and boost.
