Non Γ¨ dotato di interruttore on off quindi da collegare a prese di corrente assistite . Apparecchio arrivato con 3 giorni di anticipo perfettamente imballato . Complimenti al venditore . Review: Bought this years ago and have since retired it. Was a great EQ for simple front of house work and monitor mixes. Does exactly what you need it too and in live use is sonically clear as anyone would need. 31 bands would have been lovely but I didn't have the 2U spare at the time. ## Features - Dual 31-band, 1/3-octave constant Q frequency bands - Switchable boost/cut ranges of 6 or 12 dB - Front panel bypass switch - 12 dB input gain range - 4-Segment LED ladders for monitoring output levels - Inputs: ¼” TRS and female XLR (pin 2 Hot) - Outputs: ¼” TRS and male XLR (pin 2 Hot) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004NDHZTY | | Customer Reviews | 4.5 4.5 out of 5 stars (437) | | Date First Available | 7 August 2012 | | Item Weight | 3.58 Kilograms | | Item model number | 231s | | Material Type | Stainless Steel | | Product Dimensions | 48.26 x 15.24 x 8.89 cm; 3.58 kg | | Size | 31-band | ## Images ![dbx 231s Dual Channel 31-Band Equalizer - Image 1](https://m.media-amazon.com/images/I/61AUfqz6ZFL.jpg) ![dbx 231s Dual Channel 31-Band Equalizer - Image 2](https://m.media-amazon.com/images/I/51tm6YtspPL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Can it be used in a car?** A: At 19" wide and several inches deep, requiring a/c power, I can't envision a situation where it would be practical to use this product in a car. 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 ### ⭐⭐⭐⭐⭐ Review *by P***O on 5 September 2023* Equalizzatore grafico piΓΉ che sufficiente per uso domestico.

Does exactly what you need it too and in live use is sonically clear as anyone would need. 31 bands would have been lovely but I didn't have the 2U spare at the time. ### ⭐⭐⭐⭐⭐ Review *by A***R on 29 October 2019* This wonderful EQ is worth far more than it costs. The system: Levinson #39 transport/pre-amp, Levinson #31 amp, NHT 3.3 speakers, Transparent Reference XL cabling throughout. This setup has first class imaging, and it's now in the the best acoustic setting so far. Even so, it is a suburban house with furniture, rugs and display cases. Tested with Stereophile CD 1, there were several peaks and valleys, rather large in the <60Hz range. To the ear, the soundstage would shift a lot with just a little head movement. I've run the stereo in its new home long enough to know its imaging characteristics well for a number of favorites. The dbx 215s is between the pre-amp and amp. All connections are balanced. Before turning it on, the EQ was flattened so I could compare the soundstage before and after. What I hear is remarkable. Consider: audio imaging comes from waveforms whose phase is carefully preserved end-to-end. Any signal processing must, by its nature, delay the signal to do its magic. The 215s keeps wave phase perfectly aligned at all frequencies, at least as far as I could discern by ear or on the screen. There was no difference between the imaging with the EQ in or out. This clearly has sophisticated software on a fast DSP. Back to Stereophile CD 1. I agree with another review here: 15 bands is sufficient for tuning to an acoustic environment. The pass-band transitions are completely clean and phase-pure everywhere that's been tested. I've had two hours of tuning so far and know it can be improved even more. Heck, I'm in my office typing this and <30Hz freqs are propagating into the office as clearly as in the sound room. The reflections in the sound room are asymmetrical; I suppose that's true for everyone. This was managed nicely with left / right tuning, again using Stereophile #1. As the test tones move left and right, the reflective component of each side can be heard. As you adjust the 215s you can hear the changes tune out the reflections. With not much work the system now produces a luscious, tangible, smooth sound that pulls me out of the office to hear a song I know well - in a new way. The stereo is first-tier audio equipment, surprisingly brought to a higher level of performance by this remarkable little EQ at a price point unimaginable 5 years ago. Well done, dbx. ## 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.
