Also, electrical noise from car electronics would be a factor. **Q: If using xlr to rca connector will it make noise?** A: rca connectors are typically noisy on any application. **Q: Can the rack "ears" be cut off ? I have a very strict width limit** A: Any ears can be cut off, but I would be very careful. If you damage the corners, the integrity of the cabinet is gone. **Q: How is this compare to dbx 1231? Which model make less electrical noise?** A: hum noise depending how you are feeding all your equipment, for the money I haven't had any noise issues but this is not a traveling rig, eb tec Hum ex units would be advisable as a back up ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best eq i have used to date! Buying DBX to replace others YOU CAN FEEL THE QUALITY *by on Reviewed in the United States November 22, 2023* Purchased this unit after being frustrated with a buzz sound from my sound system, when music was paused.Disconnected my "other brand" eq and the hum went away.Purchased this DBX unit after reading many reviews. VERY HAPPY.WHen i pause the music, the system is QUIET!, the EQ allows me to adjust the sound for each environment I am in.I have now purchased 2 more DBX 15 band units to replace the "rock" EQs you see in this picture. I the HUM that I thought was a ground loop IS GONE! I spent HOURS isolating the noise. Swapping cables, running ground wires to each unit etc. All along it was the CHEAP ROCK EQs causing the issue!i have 3sets of amps and speakers depending on the environment i am in. One day i could be in a small room for a 50 person wedding. the next be playing music in a parade needing people 1 city block behind me to hear the music. ............. these DBx units are GREATBuilt SOLID, you can feel the quality! The unit has some weight, the sliders require force to move them. No more do i have to reset every time i pull the cover off my road case.FINAL FINDINGS* -- BEST EQ I HAVE USEd (over 5 different brands i have tried)* --- WOrth thE MONEY* --- SUPER QUIET (very important when you hit pause on music during an event due to an injury and the whole gymnasium is silent waiting for the performer to get up)* -- MY only regret is waiting to buy a quality item like this! ### ⭐⭐⭐⭐⭐ Fantastic! But it would have been better with black face. *by on Reviewed in the United States April 20, 2019* I replaced Berlinger 15 bands with this. Boy, what a difference! I didn't expect this will make the drastic difference in sound. I just wanted to kill the squeak noise for my stereo system and the attenuator never worked. It doesn't get rid of that noise 100 % but reduce the annoying squeak without compensating the quality of overall sound.Adding review:The high pitch squeak noise is mostly coming from voice replay of soprano and tenor, and high note of violin of orchestra. It is not constant noise, very brief moment on intense volume of singing of high note or orchestra. It drove me nuts for over last twenty years and tried everything to get rid of that from high price amplifier to speakers. But noting works and I never even thought of adding equalizer because it is used mostly sound recording, not listening.Berlinger worked but at the cost of losing the sound integrity.So I gave a chance to this dbx, and I was amazed how it works beautiful.I don't hear any noise while playing Beethoven no. 6 without losing the original sound integrity.The noise is from mostly the 3.15 K.It made my day!!!!!This dbx is the best thing I can imagine.I still can hear slight noise on vocal but I can live with it.Thanks dbx. ### ⭐⭐⭐⭐⭐ Amazing piece of kit *by on Reviewed in the United States February 8, 2023* I’ve been an audiophile purist ("straightwire with gain") for decades and have owned various bits of Class A and B gear from Apogee Stage/Audiophysik Sparks/Accoustat 1100/Proac SC1/Audio Research VT100/Audio Research VT60/McCormack DNA1 Deluxe/VPI turntables, etc. Anyway, the reason for me listing all my gear is that out of all these thousands of $ worth of equipment, this little dbx 231S has been arguably the most rewarding. It’s near silent in the audio chain and gives me incredible control over the waveform coming out of my speakers. I can’t imagine not having this equalizer in any current or future set up. At this low price, it’s a no-brainier. Get it. ## Frequently Bought Together - dbx 231s Dual 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 - dbx 266xs Professional Audio Compressor/Gate Dynamic Effects Processor with Sidechain Insert.
