Description
dbx iEQ31 Dual 31-Band Graphic EQ/Limiter with Type V NR and AFS
The dbx iEQ31 delivers professional-grade equalization and dynamics control for precision mixing and mastering work, with 40mm faders and nonconductive nylon sliders that respond intuitively to tactile adjustments across 31 individual frequency bands per channel. This dual-channel processor excels in studio mastering chains, tracking sessions requiring tone-shaping, and mix-down work, with integrated Type V noise reduction and AFS feedback suppression handling technical challenges so you can focus on capturing and refining your sound. Use it to sculpt problematic resonances in recordings, add surgical EQ to mastering chains, or manage unwanted room noise during tracking—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 studio setups.

Reviews
At a Glance
The dbx iEQ31 is a dual-channel 31-band graphic EQ with 24-bit/48kHz processing, Type V noise reduction, and PeakStopPlus limiting—designed for producers and engineers who want mastering-grade tone-shaping and problem-solving in the studio rack. Its surgical 1/3-octave control across the full audible spectrum (20Hz–20kHz), extremely low distortion (<0.003% THD+Noise), and minimal 2msec latency preserve transparency while you sculpt mixes or add final polish to masters. Choose it when you need transparent, independent processing on two channels without coloration, plus built-in tools to manage noise and peaks without reaching for extra units.
Frequently Asked Questions
What's the difference between the ±6dB and ±15dB boost/cut range settings?
The iEQ31 lets you switch each band between ±6dB (subtle, surgical adjustments) or ±15dB (more aggressive tone-shaping). ±6dB is ideal for transparent mixing and mastering; ±15dB gives you deeper cut or lift when you need to tackle severe frequency issues in live venues or problem rooms.
Does the iEQ31 handle both mic and line-level signals?
Yes. The unit accepts both line-level and mic-level signals across its XLR, 1/4-inch, and Euroblock inputs, with balanced input impedance of 40k ohm and unbalanced at 20k ohm. Maximum balanced input handling is >+22dBu, making it flexible for mic preamps, mixer outputs, and other pro audio sources.
How much latency does the iEQ31 introduce?
Only 2 milliseconds of latency at 24-bit/48kHz resolution, which is inaudible in live-sound and studio contexts and won't cause phase issues in multitrack recording or real-time mixing scenarios.
What connectors does the iEQ31 have?
XLR, 1/4-inch, and Euroblock connectors are available for both inputs and outputs, giving you flexibility to integrate into existing live-sound systems, studio racks, and broadcast installs without adapter headaches.
What do Type V noise reduction and AFS feedback suppression do?
Type V noise reduction provides up to 10dB of dynamic broadband attenuation to clean up hum and background noise, while AFS (automatic feedback suppression) identifies and notches feedback frequencies in real time—essential tools for live venues and challenging acoustic environments.
