Interphase Audio Iridium Value Pack

Interphase Audio Iridium Value Pack gives you two Iridium modules in one product box, so you can build a more flexible setup right away. If you need a premium EQ solution with real character, the Iridium Pair delivers that in a compact, practical format.

The Interphase Audio Iridium is a single-channel module with a 4-band inductor EQ. In addition, it brings the classic inductor sound into a modern design that feels musical, precise, and expressive.

Inductor-based circuits are often considered the holy grail of equaliser design. For example, legendary designs such as the Pultec EQ used inductors and helped define the sound of recording in the late 1950s. As a result, engineers still value this approach for its smooth, distinctive tonal shaping.

Iridium uses 16 inductors across its four bands. Furthermore, custom-wound inductors in the low-mid and low bands give you accurate control and a rich inductor character where it matters most. This design helps each band respond with clarity and musicality.

Because it uses a Class-A discrete circuit, Iridium sounds open, refined, and highly musical. Each component is carefully selected and matched, so the module delivers a consistent and distinctive result. Consequently, sound engineers can shape tone with confidence and keep the source feeling alive.

Iridium is a unique product

At the same time, Iridium is not a clone or copy of a vintage unit. Interphase Audio designed it with modern techniques and contemporary components that were not available 60 years ago. Therefore, it offers a fresh take on classic inductor EQ rather than a reproduction of an older circuit.

The inductor design creates a peaking, or bell, response on each band. This gives you tight control over the selected frequency and helps you make focused EQ moves. In practice, that means you can shape tone with precision while still keeping a musical feel.

Each band also gives you switchable frequency selection. You can choose from six carefully chosen frequencies per band, and those frequencies sit at musically useful intervals. As a result, you can work quickly and land on strong settings with less guesswork.

Finally, each band offers up to 15 dB of cut or boost. That range gives you enough flexibility for subtle correction or more dramatic tone shaping. Iridium Pair therefore gives you a powerful, musical, and modern EQ solution with a classic-inspired voice.
