Review: ... different sections of my PA rig and I'm very happy with the general build quality and performance of the ... - This is my third purchase of a DBX EQ for different sections of my PA rig and I'm very happy with the general build quality and performance of the units. Light but sturdy, just enough features to be very useful without being too complex, and they do a great job to set up the sound perfectly for each venue that I sing at. This single channel unit is being used for my microphone and is just what I needed to get the type of sound that I want from the mike. It rack mounts very easily and has either XLR or quarter inch jack inputs/outputs so it's quite versatile. I'd recommend this type of EQ to anyone involved in live music production as it really does help with screening out feedback at high volumes without losing too much of your mix, plus you can alter specific frequencies in your sound to best suit the acoustics for the room you are setting up in. Good job DBX!

Alesis Q2 > Dbx131z > Vox AC15 produced an annoying mid-to-high frequency hiss (no guitar signal *by E***L on 8 October 2016* Chain - Guitar > Alesis Q2 > Dbx131z > Vox AC15 produced an annoying mid-to-high frequency hiss (no guitar signal; mid freq.- high freq. sliders at +12dB). When the Dbx131s was removed, the noise was gone. When the Dbx131s was replaced by an MXR Ten band EQ with sliders at equivalent position, the noise was gone. Very dissappointing. Unit returned and awaiting refund. ## Frequently Bought Together - dbx 131s Single Channel 31-Band Equalizer - Cable Matters 2-Pack Premium Short XLR to XLR Cables - 3ft, Male to Female Microphone Cable, Oxygen-Free Copper (OFC) Mic Cord, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/51831217-dbx-131s-single-31-band-constant-q-graphic-eq](https://www.desertcart.pt/products/51831217-dbx-131s-single-31-band-constant-q-graphic-eq) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-19*
