The IP211 is the middle input module of the Ark8
It’s designed to add colour to the signal paths.
The IP211 has 4 sections, which can be combined on the same signal path or used independent from each other on either the small fader or large fader signal path.

Hi Cut filter
As it’s name implies, the Hi Cut filter cuts off the high frequencies. It sweeps over 5 octaves from 16 KHz down to 500 Hz (this is also called a Low Pass filter)
The Hi Cut filter can be used on the Large Fader or Small Fader Path.
Lo Cut filter
As it’s name implies, the Lo Cut filter cuts off the low frequencies. It sweeps over 5 octaves from 25 Hz up to 800 Hz (this is also called a Hi Pass filter)
The Lo Cut filter can be used on the Large Fader or the Small Fader Path.
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, giving precise control and the distinctive inductor sound on each band.
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 fader - instead of a rotary potmeter - for cut and boost control, allowing a maximum of plus or minus 15dB.

Four bands with switchable, overlapping fequencies
- 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

Why faders instead of rotary potmeters ?
Simply, because we like it.
But also, because in our opinion, this gives much better visual control of the level of cut or boost, so you immediately know what is going on.

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.
Our Swing EQ can be used on the Large Fader path or on the Small Fader path.

All four sections of the IP211 can be used independently from each other, on either of the signal paths, or can be combined for “extreme” EQ-ing.
