dbx iEQ31 Dual 31-Band Graphic EQ/Limiter with Type V NR and AFS

dbx iEQ31 Dual 31-Band Graphic EQ/Limiter with Type V NR and AFS

The dbx iEQ31 puts professional-grade equalization and dynamics control at your fingertips, with 40mm faders and nonconductive nylon sliders that respond intuitively to tactile adjustments across 31 individual frequency bands per channel. This dual-channel workhorse delivers surgical tone-shaping suitable for live sound reinforcement, studio mastering, and broadcast applications, with integrated Type V noise reduction and AFS feedback suppression handling technical challenges so you can focus on the mix. This tightening up a muddy live mix, adding pristine processing to a mastering chain, or controlling feedback in challenging venues, the iEQ31 adapts to your sonic requirements with complete confidence and control.

Audio Performance & Processing

The iEQ31 delivers 113dB dynamic range and exceptionally low distortion at <0.003% THD+Noise (typical at +4dBu, 1kHz), ensuring transparent signal conditioning across your frequency spectrum. Its 24-bit digital resolution at 48kHz sample rate with only 2msec latency provides studio-quality fidelity with minimal phase shift, while the 20Hz–20kHz frequency response (±0.5/-0.25dB) captures the full audible spectrum with exceptional accuracy.

Connectivity & Specifications

The unit offers flexible I/O options including XLR, 1/4-inch, and Euroblock connectors for both inputs and outputs, with balanced input impedance of 40k ohm and unbalanced at 20k ohm. Maximum input handling reaches >+22dBu balanced or unbalanced, and output reaches >+20dBu into 2k ohm or greater loads, accommodating both line-level and mic-level signals in professional installations.
