IP211 EQ module

The IP211 module can be installed in the middle input section of the Ark console.
Our EQ 2.2, EQ 8-R and EQ 8-Ex make use of multiple IP211 modules.
IP211 features
* Dual Audio Path / 2 inputs and 2 outputs per module
* Hi-Cut Filter
* Lo-Cut Filter
* 4-band Inductive EQ
* Swing EQ
* Each EQ section can be used on either Audio Path

Hi-Cut filter (also called Low-Pass filter)
As it’s name implies, the Hi-Cut filter cuts off the high frequencies.
It sweeps
down 5 octaves from 16 KHz to 500 Hz
Our Hi-Cut filter can be used on the A or B signal path, and separate or in combination with the other EQ sections.
Lo-Cut filter (also called Hi-Pass filter)
As it’s name implies, the Lo-Cut filter cuts off the low frequencies.
It sweeps
up 5 octaves from 25 Hz to 800 Hz
Our Lo-Cut filter can be used on the A or B signal path, and separate or in combination with the other EQ sections.
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, 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 EQs on the market), giving precise control and the distinctive inductor sound on each band.
Inductors provide a “peaking” characteristic, giving much tighter control of the frequency selected.
The values and components have been carefully chosen and matched to provide an extremely musical sound.
Each band provides switch selection of any of six frequencies chosen at musically pleasing intervals.
Each band uses a fader - instead of a rotary potmeter - for cut and boost control, allowing a maximum of plus or minus 15dB.
Our 4-band inductive EQ can be used on the A or B signal path, separate or in combination with the other EQ sections.

Four bands with switchable, overlapping frequencies
- Low : 50, 80, 100, 150, 300, 600 Hz
- Low Mid : 125, 250, 500, 1K, 2K, 4K Hz
- Hi Mid : 2.5, 3, 5, 6, 7, 8 KHz
- High : 8, 9, 10, 12, 14, 16 KHz
But why faders instead of rotary controls ?
Honestly … because we like faders.
But also, because in our opinion, this gives much better visual control of the level of cut or boost, so you know what’s going on in a glance.
Swing EQ
Our Swing EQ is a fast and easy way to make a track sound “warmer” or “cooler”.
By turning the one-control-knob counterclockwise, you attenuate the highs and boost the lows, making the sound darker.
By turning the one-control-knob clockwise, you attenuate the lows and boost the highs, making the sound brighter or cooler.
Our Swing EQ can be used on the A or B signal path, separate or in combination with the other EQ sections.
