Our Products


Originally designed as the middle section for the Ark input channels,
the EQ 8 is the rackmount version of this middle input section of the Ark.
The EQ 8 is designed to add colour to your signal, and silky smooth colour that is.

The EQ 8 features 8 of our
IP211 modules with 4-band Inductive Equaliser, Hi-Cut filter, Lo-Cut filter and Swing EQ.
The EQ 8 is fully modular.
Each module has 2 in- and outputs, and 2 audio paths, actually making it an EQ with 16 I/O

Each of the four EQ sections - of each module - can be independently used on either “A” or “B” audio path

The EQ 8 has 8 channels, with 2 audio paths and 2 in- and outputs each.
Each channel has 4 EQ sections.
All four sections of the EQ 8 can be used independently from each other, on either of the audio paths of each channel, or can be combined for “extreme” EQ-ing.

The Interphase Audio EQ 8 is available as a full 8 channel version or an expandable 4 channel version.
These can be ordered
directly from us or from your favourite pro audio dealer.




Each module (channel) of the EQ 8 contains 4 EQ sections.
- Hi-Cut filter
- Lo-Cut filter
- 4-band Inductive Equaliser
- Swing EQ


IP211 layout


Hi-Cut filter (also called Low-Pass 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
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 over 5 octaves from 25 Hz up 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 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 fader - instead of a rotary potmeter - for cut and boost control,
allowing a maximum of plus or minus 15dB per band.

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 (Hz): 50, 80, 100, 150, 300, 600
- Low Mid : 125, 250, 500, 1K, 2K, 4K
- Hi Mid (kHz): 2.5, 3, 5, 6, 7, 8
- High : 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.


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.


All our EQs are based on the IP211 EQ module from the Ark console.
Full details can be found on the
IP211 page

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

Inputs and outputs? We’ve got you covered.
The EQ 8 features the most common connectors for all inputs and outputs, so no need to worry about connections.

Inputs have female XLR, balanced jack and D-Sub connectors.
These connectors are paralleled, you can use either of them (per channel).
It’s not a good idea to use multiple input connectors (per channel) at the same time.

Outputs have male XLR, balanced jack, and D-Sub connectors.
These connectors are paralleled, you can use all of them at the same time, so outputs can be split to multiple destinations.

Below are some short movies of the EQ 2.2 (VU)
and a movie of the EQ 2.2’s big brother - the EQ 8.
EQ sections and routing on the EQ 2.2 and EQ 8 are the same, so either movie should give you a good idea.
