This is the DIY version of our Helium 500 module.
It comes as a partial kit, with all hard-to-get parts and full instructions.
You'll need to get standard parts (like resistors and capacitors) yourself.

Helium is an advanced build intended for DIYers who have already built at least a couple smaller projects. You should be confident in your soldering ability, and be able to identify the correct orientation for capacitors, semiconductors and diodes. We advice against ordering this if your are just starting with DIY. 


Helium - 4-band Hybrid EQ

Helium combines capacitor based EQ circuits and filters with inductor based EQ circuits.

Helium is the combination of our Carbon and Iridium EQ, with extra filter circuits added.

Helium 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, Helium is unique and features great sound and straight forward functionality.

The four 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 bell-curved EQ or as HI-Cut / Lo-Cut filter.

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