Official description
PEQ-503 Equalizer

Single-channel three (3) band Inductor-based equalizer, designed for the popular API VPR500 Rack format

The FiveFish Audio PEQ-503 is a beautiful, high-quality, single-channel three (3) band Inductor-based equalizer, designed for the popular API VPR500 Rack format.

Each frequency band has two (2) selectable frequencies, and a bypass switch. It also has an overall EQ In/Bypass switch to let you easily make before & after sound comparisons.

The equalizer's smooth broad curves makes tonal adjustments easy and fast. You can go from small, subtle changes to extreme carving or boosting, up to +/- 18dB per band. The SUB and AIR frequency bands can give your tracks the chest-thumping punch you want, and that extra sparkle at the top end without sounding harsh. The mid frequencies band takes care of adding that extra presence to your tracks to make it pop.
