Featuring switchable ±6/±15 dB boost/cut ranges, balanced inputs/outputs, and advanced noise reduction technology, it delivers pristine sound clarity and precise frequency shaping. Its rugged 3U chassis and intuitive LED feedback make it a reliable centerpiece for any high-end audio setup. ## Description The dbx® 12 Series were designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls. The 1231 provides standard features like dual-channels, 31 1/3 octave bands, ISO frequency centers, +/- 12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also includes other insightful features. These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS connectors for installation ease; balanced inputs and outputs for quiet operation; and chassis/signal ground lift capabilities for quick hum isolation. The visionary design of the dbx 12 Series makes your job easier. The dbx 12 Series Equalizers were precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transformer, electronically balanced/unbalanced inputs and servo balanced/unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with 2 second power up delay were steps our engineers took to ensure compatibility for all installations. Only the best components were utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR (ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail is contained in a 3U steel/aluminum chassis. ## Features - Dual-channels, 31 1/3 octave bands.

Your add says a DBX 1231 Your picture is a 2231 which is it** A: Jeff, the Amazon catalog has the wrong image. Image feedback request has been sent to Amazon to fix this issue. This product is the DBX 1231 Dual 31 Band Graphic EQ. Thanks Jeff-Pro Audio Land **Q: can each channel handle a stereo input?** A: Yes You can apply either channel of your sources L/R output to the 2131's Channel 1/2 input. It doesn't matter, as long as you keep your signal flow SEPARATED and in series. I never use RCA connectors. This device was primarily designed for Balanced 3 pin audio input &outputs. The use of RCA connectors only minimizes system hum & noise. This defeats the purpose of this devices noise reduction circurty. DBX realizes this. That is why they did not make RCA connections available on this device. 98% of consumer audio systems (home) use RCA connectors not Professionally balanced 3 pin audio connectors. That is the beauty of this device. Don't try to mix apples and oranges. If the connectors are not there they are not meant to be. Hope this helps.n Doc **Q: Are the sliders illuminated?** A: No they are not illuminated ## Frequently Bought Together - dbx 1231 Dual-Channel, 31-Band Graphic Equalizer, Black - J&D 1/4 to RCA Cable, Gold Plated Copper Shell Heavy Duty 2X6.35mm TS to Dual RCA Stereo Audio Interconnect Cord for AV Receivers, Speakers, Home Audio Systems, Amplifiers, 6 Feet - J&D Dual 1/4 inch TS to Dual RCA Cable, Heavy Duty 1/4 Male to RCA Male Adapter Stereo Audio Interconnect Quarter inch Cable, 6 Feet --- ## 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.ph/products/707464-1231-dual-channel-31-band-graphic-equalizer-black](https://www.desertcart.ph/products/707464-1231-dual-channel-31-band-graphic-equalizer-black) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-08-13*
