Home Audio Equalizer, Professional 31-Band Digital Equalizer,Noise Reduction Rack Mount Audio Spectrum Analyzer,Stereo graphic equalizer Real-time frequency level display

FULODE EQ315I've been looking for a comprehensive EQ/Spectrum analyzer for my home theater system and have found much of the equipment offered today as lacking in true functionality, especially regarding an ACTUAL real time spectrum analyzer. Many claim theirs has this but they are really just a fake light show that moves to the beat.I read the reviews here, some very helpful, some not so much and took a chance on this EQ315. I've been putting this thing continually through it's paces now for the last 3 days and am frankly very impressed with it overall. 'Burning in' a new electrical component is something I typically do. I'm only using the RCA in/out connections, so I can't comment on the other connectivity available on the back panel. If you need more RCA connections you can simply use XLR to RCA adapters for inputs and outputs, that would include the adjustable Sub line XLR output on the rear.My takeaways:PROS:- Construction of the case and front panel/switches are quite good. It appears and feels well made.- The unit runs very cool with little noticeable heat generated.- It performs well as intended and expected. The curves I programed into the memory do a respectable job attenuating each band as desired. All 10 bands are set default flat from the factory.- The spectrum display is very fast and accurate to each band. Each individual LED in each band is controlled individually so the most detail can be controlled and observed. I like the 3 colors used which makes for a more interesting and informative display. The bottom blue LED for each band is useful for indicating (by flashing) which band is being currently tweaked.- The Bluetooth works quite well. I connected an iPod very easily and streamed music seamlessly. Note: the blue Bluetooth indicator LED blinks when connected to a source and the track control buttons on the front panel work nicely. It will show up as 'EQ31SUB' on your device.- The unit doesn't generate any discernable noise.- Being able to control each of the 31 bands is a plus compared to the usual 12 on most other EQs.- I'm not sure about the comment claiming it times out and shuts off automatically. Mine has been on for 3 days straight without issue. Perhaps this has been corrected.- The discrete Sub Bass output and controls are a nice touch and I plan to use it to feed one of my dedicated Subwoofer amps.CONS:- The instruction manual is just OK. Many misspellings, typos and poor grammar, but you get the idea. It also doesn't explain several features of the unit including Bluetooth and the Sub bass line output adjustments on the back.- It is NOT U1 rack size, it's face is taller at 2 1/16" or 52mm. Add a little for the feet if you are stacking like I am.- The power switch is on the rear. It would be better in many setups to be accessible on the front. Solution: I plugged it into a switched outlet on the back of my main Amp.- Yes, the RCA L&R inputs color coding are reversed. Should be red for Right. FULODE printed the correct channel (R / L) on the case. Interesting as I though this was an industry standard :-/- Creating and saving your own EQ curves is a bit confusing at first, but it's somewhat intuitive.- You only have control (and display) of both R&L channels together so you can't tweak channels individually, however the R & L channels are still discrete. This would be a neat unit if you stacked R&L individually in the same component. This isn't an issue for me but could be for a purist.- The display is a bit bright when in a dimly lit room. A dimming adjustment for this would be a nice feature.- The case should have removeable rack mount brackets for those (like me) that do not use a rack setup. It does fit my cabinet as is, but I may cut the flanges down to fit and look better at a later date.Conclusion: As you can see, I certainly didn't need another EQ, but I'm very impressed with this unit for use in my home theater setup. The Pros definitely outweigh the Cons. This thing looks, connects and performs the way I need it to. Seems to be a pretty good value for what you get. Take this from an old guy who grew up in the golden era of Hi-Fi equipment and who previously owned a complete rack of brushed silver Pioneer blue fluoroscan stereo equipment. If you know - you know.

If you cannot figure out why your brand-new speakers do not sound as good as they did in the store, it may be the room acoustics. The Fulode equalizer is a marvelous little gem for correcting that issue. I purchased the non-computer-controlled version for $138 in June 2025.I placed a calibrated microphone at my seating position while using the free software, REW, to adjust my speaker and room acoustics such that the frequency response at that location was flat. Why flat? You want it flat to reproduce sound to match what the artist intended while in the studio. If you want to change or “color” the sound as done using typical bass and treble controls, you can, but with much finer control. In fact, you are the sculptor of your own sound. You have complete control with 31 bands of adjustment. I have included a picture of my room’s frequency response with and without equalization. Without equalization, the sound was “thin” in that it lacked low end including vocals along with a brassy high end. This is seen by a 25 db difference between 300 Hz and 1.6 kHz. With the correction in place, the whole frequency range is within +/- 3dB. This is what one would expect from a $3000 to $5000/pair of speakers. This correction took my homemade speakers to the stratosphere with regards to audio fidelity. The sound is beefy down low, provides vocals up front where they are supposed to be, and exhibits clear articulation between instruments. Your mileage may vary since not all speakers and/or rooms are fixable with equalization.Since I was testing this unit with a Fosi class D amp with no sub out, I found the sub out on the equalizer to be a welcome addition. My only complaint is that the sub output is limited to a type XLR. The mains have both ¼” TS and RCA outputs. I needed an XLR gender changer and an XLR to RCA cable to connect to my subwoofer.The unit plays MP3s off a thumb drive with no issues, and it had no problem finding my android phone using Bluetooth.All in all, this unit is a great buy. I plan on getting another and bi-amping my speakers eliminating the need for expensive crossover parts.

The idea of this product is amazing and the different features was just as good however the product was defective. I wasn't able to connect to Bluetooth after trying multiple times. I requested a replacement however wasn't given one. I had to reorder another in hope that it works properly. A refund isn't always the solution. Unless requested. In addition I used my reward points and was deprived of the full value of my points. Each point used receives less of its value e.g. $1 equals to $0.08 of buying power. Then the Amazon supervisor was rude and less helpful by hanging up the phone in the middle of the call and before a solution was met. I find it difficult to trust Amazon as an option to buy goods especially since Amazon claims they have no say to the third party goods being sold through Amazon network and third party is just as indifferent to professionalism and making a wrong, right, without the consumer. There wouldn't be an Amazon or third party sellers. My commentary serves as a part of the experience with this device and a viewpoint of being treated disrespectfully without merit. I've earned my reward point and should be able to use every points completely.

Been using this for a while, and I have gotten used to whatever quirks there are. The sound of the EQ is fine, it's a basic thing to set up and I'm sure anyone looking into buying would know how to do that. So the basic inputs and outputs are easy to see in the images. One output that is handy to have is the sub out. There is also a Bluetooth connection but frankly I'm not sure of what use it is. The 2 issues I had with it is as far as I have been able to tell is that even though it is stereo, you can only control both channels simultaneously. At least I have not been able to change the EQ levels interdependently left and right. For the most part that is OK for the live setting I am using it for. But in other situations, that would be a bit of and issue. The second difficulty is that the LED's are way to bright. I wish manufactures would ALWAYS include a dim knob. The brightness is so bright I had to cover it with a piece of dark paper to get it to be acceptable it low light situations. You can save settings but its a bit strange to recall settings unless you write down what you had, or maybe take a photo of the EQ. So for some uses it is a decent EQ, as far as the way it sounds. But the functionality is a bit unusual.

So far so good this is exactly what I was looking for having no problems with it and it looks very cool. Doesn't seem to downgrade my sound quality either. Now just a waiting game to see how long the unit lasts. Remember don't let your meters stay in red for long it's OK if it dips into it for short periods of time try to keep it away from red so you can avoid clipping.

Great functionality; bars and visuals are even and smooth, bright but not overbright either. The unit does get warm, but otherwise I've found no issues or problems. Recommended for pro or casual PC/Entertainment systems.

Not user friendly if needed to make individual audio frequency adjustments on the fly quickly.

No issues, works as it should. The only thing I found somewhat confusing was that in two places in the instructions it mentioned that it was 220 volts AC but the unit was supplied with a 110 volt style plug so I went ahead and plugged it into 110 volt outlet...works perfectly.

Very good equipment easy to use and great effect.

Agréablement surpris !! très bon article

Cet article fonctionne bien et fait ce qu'il se propose de faire. C'est un bel ajout dans mon rack de sonorisation. Cependant les entrées et sorties Jack 1/4 sont très mauvaise qualités car elles créent du bruit à cause des très faible contact contacts à l'intérieur de ceux-ci. C'est tellement mauvais et grossier comme problème que si je n'avais pas essayé en utilisant exclusivement les entrées et sorties XLR, le produit aurait été bon seulement pour la poubelle. Mais en évitant complètement les entrées et sorties Jack c'est un produit intéressant et fun à utiliser.

Très bon produit

This equalizer is awesome!I was looking for a visual display for my home theater audio, and it looks amazing!!It would be cool if it supported eARC audio input in future models.I managed to get it to monitor my eARC audio with a couple of external Orei devices ;) 1 eARC splitter, and 1 eARC to RCA converter. Fed that audio into the RCA input of equalizerPERFECT!!
