The 1/3rd Octave EQ in ARC DNA combines classic tuning structure with the speed, precision, and flexibility of modern DSP. Featuring 31 bands per output channel, this EQ gives users a familiar graphic interface with serious technical power under the hood. Frequency points follow traditional 1/3rd octave spacing, and each band can be adjusted in 0.1dB increments, from +18dB to -24dB, for smooth, transparent tuning with definition and clarity.

What sets it apart is its scalability and control. When connected to any ARC Audio DSP, DNA instantly populates the EQ panel based on the processor’s exact output configuration—no wasted controls, no clutter. Channels can be tuned individually or globally, and linked or unlinked in any variation or combination in real time, allowing for precision and speed at every stage of the tuning process.

The 1/3rd octave EQ is ideal for users getting started with DSP tuning. It offers a clear path to tonal control without the intimidation of advanced filter design. Simple, traditional, and powerful, it gives you the tools to build a personalized response curve that suits your listening style—whether it’s a mild OEM upgrade or a competitive front stage.
