As one of the few manufacturers of
consoles with 500 series support,
we simply had to design 500 modules.

We currently offer three different EQ modules.
Other modules are in the works and will be released over the coming months.

Carbon


4-band Capacitive Equaliser

Carbon is your basic building block, your “go to” EQ
With it’s four large overlapping frequency bands you can go wild with this EQ.

Capacitor based EQ circuits can be considered the “classic” equaliser design, as used in a lot of well known EQ’s
Carbon is our own take on this classic EQ.

Carbon is a full Class-A, discrete design, and all components have been carefully chosen and matched to provide an extremely musical sound.
This is definitely not a “clone” or “copy”
(we at Interphase Audio do not build clones or copies of anything).
Like all our products, Carbon is unique and features great sound and easy-to-use functionality.

The four EQ bands have large overlapping frequency controls, making it well-suited for minimising problematic frequencies, or giving an extra boost to others.
The HF and LF band can be used as either shelf or peak, for extra punch, dimension or control of high- and low-end.

Each band can be cut or boost with as much as 15dB per band.

Carbon is available in 3 versions:
* Carbon : 500 module
* Carbon 51x : 51x module
* Carbon DIY : Build-it-yourself module kit

All 3 versions are available with “Silver” or “Black” faceplate
