The dB 131s includes a single 31-band channel of 1/3-octave equalization, 12 dB input gain, switchable 6 dB or 12 dB boost/cut range, 20mm nonconductive sliders, an intuitive user interface, and output level metering. From its extended 10Hz to 50kHz frequency response and 110 dB dynamic range to the quality componentry and meticulous attention to detail, The 131s offers exceptional sound and rugged reliability that s you will always sound your best. Sure to find a home in the studio, on tour and with installed sound venues, The dB 131s is destined to take its rightful place in the lineage of great dB signal processors that are the professional's choice in signal processing. With such affordable quality, There's no longer any excuse for compromising your sound. Review: All guitar playes need this - This EQ first of all has great sound quality. No issue with noise. Put this in your effects loop. Take any high gain amp channel and shape it into the sound you hear on recordings. It's all in the EQ. All of the classic rock tones, metal tones, fusion tones......it's not your amp; it's your EQ. Review: This unit meets the need - 31-band EQ's have several uses in the chain of audio production, several of them may only require a single channel. While it would surely be "economically prudent" to buy two-channel EQ's from the start, when the need requires a single channel only (as with a single microphone installation, perhaps,) the dbx 131s is a reasonable choice. I have not found any reason to question it but I would suggest you take all the time necessary to understand where an EQ works and what it cannot do. It can, along with other tools in the chain, clean up and clear up certain issues, but know that it does not replace processors designed to limit, shape or expand the signal. I use mine to help isolate a particular sound quality, and I rely on additional tools to complete this process. For what it does, it works transparently and well. ## Features - Single 31-band, 1/3-octave constant Q frequency bands - Switchable boost/cut ranges of 6 or 12dB - 12dB per octave, 3dB down @ 50Hz low-cut filter - Front panel bypass switch - 12 dB input gain range - Inputs: ¼” TRS and female XLR (pin 2 Hot) - Outputs: ¼” TRS and male XLR (pin 2 Hot) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004NB8WU2 | | Best Sellers Rank | #14,062 in Musical Instruments ( See Top 100 in Musical Instruments ) #14 in Equalizers & Feedback Controllers | | Customer Reviews | 4.4 4.4 out of 5 stars (49) | | Date First Available | February 11, 2011 | | Hardware Platform | CONSUMER_ELECTRONICS | | Is Discontinued By Manufacturer | No | | Item Weight | 4.8 pounds | | Item model number | 131s | | Product Dimensions | 19 x 6 x 1.75 inches | | Size | 31-band | ## Images ![131s Single Channel 31-Band Equalizer - Image 1](https://m.media-amazon.com/images/I/51mR1ei6P4L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ All guitar playes need this *by T***M on November 28, 2023* This EQ first of all has great sound quality.
