dbx 530 Parametric EQ – 500 Series

The dbx 530 delivers surgical parametric control with tactile, responsive knobs that provide real-time feedback as you shape tone across the full frequency spectrum. This compact 500 Series module excels at sculpting vocals, drums, instruments, and complete mixes with transparent, clean EQ characteristics. Trusted by professionals across studio tracking, live sound, and broadcast applications, the 530 rewards both your ears and hands with intuitive, musical results.

Audio Performance & Signal Integrity

The 530 maintains exceptional clarity throughout your signal chain, with a −90 dBu noise floor (unweighted), 112 dB dynamic range, and THD+Noise under 0.006% typical, ensuring your source material remains pristine. Electronically balanced/unbalanced inputs and outputs with RF filtering accept levels up to +22 dBu, making the module compatible with both line-level and hot sources while delivering transparent gain staging.

Parametric EQ & Frequency Control

Three independent EQ bands deliver surgical precision: low band (20–500 Hz), mid band (200 Hz–5 kHz), and high band (800 Hz–20 kHz), each offering ±15 dB of cut or boost with adjustable Q. Each band operates as a symmetrical peak/dip filter, with high and low bands switchable to shelving mode and all three capable of Infinite Notch mode for eliminating problem frequencies without affecting surrounding content.
