Interphase Audio Carbon 500 Series Equalizer (Demo Deal)

The Interphase Audio Carbon is a basic building block, “go to” EQ in 500 Series module format with four large overlapping frequency bands that allow you to go wild. Capacitor-based EQ circuits are considered the “classic” equalizer design, and Carbon is based on this design. Carbon features a full Class A, discrete design with all components having been carefully chosen and matched to provide an extremely musical sound.

The four EQ bands have large overlapping frequency controls, making them well-suited for minimizing problematic frequencies, or giving an extra boost to others. The HF and LF bands 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 boosted by as much as 15 dB per band.

This is definitely not a clone or copy. Like all Interphase Audio products, Carbon is truly unique and features great sound and easy-to-use functionality.
