Review: Excellent et très utile - Le son qui sort d'une chaîne hi-fi est souvent un peu agressif. Cela semble dû à deux facteurs principaux : * Une dynamique très forte, surtout avec les CD de fabrication récente. Ce qui explique je pense la vogue renouvelée du disque vinyl dont la dynamique, bien que déjà respectable, est un peu moins forte. * Une intensité trop grande du "medium", c'est-à-dire des fréquences de l'ordre de 500 à 1000 Hz : les attaques de notes au piano fatiguent l'oreille, de même la flûte, les voix de femmes. Avec cet appareil, on ne peut pas jouer sur la dynamique, mais on a un parfait contrôle de tonalité, on peut l'organiser exactement comme on veut, et changer d'avis n'importe quand. Il en résulte un confort, un agrément d'écoute, très amélioré. Review: Excellent graphic equaliser. - Its a nicely design product that fuilfill your music taste. Initially I was in doubt about its sound quality but when tested with my DIY dac cum amplifire it shows its charecteristics. Background noise is absolutely not hearable and sound is clean particularly at 12 db mode. Voice is clear with ample amount of bass charecterictics within. Only negative aspect is light plastic body which is not firm on its base and often get shifted from its position due to audio input/output jack cable rigidity. Also may succeptible to outside interferance due to plastic body that may allow high frequency to pick up by the internal circuits. Go for it, it will serve your purpose. ## Features - Ultra compact 9.5" graphic equalizer for studio and stage applications - Revolutionary fbq feedback detection system instantly reveals critical frequencies and can also be used as audio analyzer - Additional low cut filter removes unwanted frequencies, e.

On the back there are two options for input and two options for output. Those can be either guitar plugs or the typical red/white RCA plugs (left and right channel). You run your source signal (iPad, phone, cd player, etc) through the input on the back of this EQ and then run the output on the EQ to your amp, which would then be connected to your speakers. Personally, I find this extremely mobile EQ to be perfect for connecting between my iPad headphone jack (to the Behringer input on the back) and my ION Block Rocker boom box speaker which is battery operated or powered from an AC outlet. The Behringer does have to be plugged into an AC outlet in order to function. Otherwise I could use the hole system without any electricity around. Look into the ION. It is a fabulous stand alone speaker which can be found at Sams or online for around $125 to $150. And when you tweak it with the Behringer, it is a fantastic combo. **Q: I see many mention that they use this for helping hearing loss by using this unit with headphones. My question is how do you use this with headphones?** A: As another person noted, if you have a particular limited range of sound where the hearing loss is concentrated, then this can help. I have hearing loss from 1.5K to 8K but concentrated at 5k. I hook the equalizer up from the headphone jack of the TV as input and then to powered bookshelf speakers as output. But, you could easily go right to headphones instead. You would need probably two adapters. A 3.5mm male stereo plug to 2 male RCA adapter, and a 3.5 mm female stereo to 2 RCA male plugs adapter, both available on Amazon as I'm sure elsewhere. Plug the first adapter into the headphone output jack of the TV or stereo and into the RCA inputs in the equalizer, then plug the 2nd adapter into the equalizer RCA outputs. Finally plug your headphones into the female plug on the second adapter and enjoy. **Q: Can you adjust each channel (left/right) separately?** A: No you can't. Even the other functions (Low-Cut, Level) are applied to both channels simultaneously. At the extremely low price you could always get two units, one for each channel but Left and Right channels are almost always treated identically anyhow. **Q: What type of cables are required to hook this up between an amplifier and yamaha receiver? Much appreciated.** A: RCA ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent et très utile *by Z***U on 15 November 2017* Le son qui sort d'une chaîne hi-fi est souvent un peu agressif.

Initially I was in doubt about its sound quality but when tested with my DIY dac cum amplifire it shows its charecteristics. Background noise is absolutely not hearable and sound is clean particularly at 12 db mode. Voice is clear with ample amount of bass charecterictics within.

Also may succeptible to outside interferance due to plastic body that may allow high frequency to pick up by the internal circuits. Go for it, it will serve your purpose. ### ⭐⭐⭐⭐⭐ Probably the cheapest and best EQ you can buy for the money *by H***B on 14 January 2017* Very good device. I use it to change the sound of my electric piano towards the monitors (add more brightness and low end, and reduce some sharpness). It works really well for this! It's a virtually noiseless device, save for when you dial up the volume. At 12 o'clock input volume it sends out the signal 100% of volume as it receives it. Past 12 o'clock, it boosts up the signal. So if your output of your device is pretty low, this device will actually boost the overall volume by around 12dB. Additionally, the 9-band EQ can also boost/cut the volumes upto +/- 12dB. The buttons are pretty self-explanatory. It has a 75Hz cutoff, that will protect your speakers in case of some low frequency popping (like cable disconnect, or so). The second one, is one of those buttons that don't make a lot of sense. In/out is actually to turn on or off direct sound. When pushed in, the light is on, and all buttons and eq of this device work. When off, the sound input is directly routed to the output. In my opinion it makes no sense, because if I wanted to have a direct line, I wouldn't have put this device in between the signal cables. In other words, I think by default this led light and button needs to be OFF, and they need to change it to 'DIRECT', instead of 'In/out'. Meaning, the majority of the time, I will be using this device. The LED doesn't need to be on all the time. But anyway... the 'Input output' button allows you to select to see either input or output volume levels on the eq. It allows you to see if the input level is too hot, or the output level is too hot. The 9band eq works well, however, with the volume dialed past 12 o'clock, the device creates some hiss heard in the last two frequencies (especially when they are boosted) (8/16kHz). FBQ, no idea what this does, however all eq slider leds go off when selecting it, and when playing a tone, the frequency matching closest on the EQ slider will light up. This might be helpful for beginners, when trying to get rid of annoying feedback, or too much frequencies in the room. One can use FBQ to see which frequency offends (the led will turn on), and reduce the volume on that slider. Personally, I don't use it. Anyone with 1 year of more of sound engineering, or who is careful about the sound quality and has worked with mixers before, won't need this feat. Another issue with this is that I've found that some of these leds, actually stop working within a year time. So if you ask me, it's a useless feat, that could have been removed so that the overall price of the device would be reduced. In fact, I wonder why Behringer hasn't yet created a bluetooth operated device that can be controlled by a bluetooth phone and app. No control sliders, no buttons save for power, and perhaps 1 to 4 different modes (banks) that can be saved via the phone. This would easily half the price of the device. Anyway, further on the real device review: 6/12dB allows you to select the range of EQ amplification/cut. The EQ sliders from center up to the max will boost the signal by either 6 or 12dB depending on the slider. 6dB is for fine adjusting. 12dB allows you to adjust some signals that are seriously offending to the ear, and reduces them to a more tolerable sound, better fitting the other frequencies in the spectrum. power button back side allows for 2x mono jack, and 2x kinch inputs, as well as the same outputs. Probably the cheapest and best EQ you can buy for the money, Does what an EQ is supposed to do. Great for adjusting sound of music instruments (piano to monitor, guitar to combo, bass to bass rig, acoustic-electric guitar to stage monitor, flute microphone to mixing board,... the possibilities are endless...), home theaters, even changing the overall sound of a PA system right before the signal enters the power amps. ## Frequently Bought Together - Behringer 10 String Multi Effect Processor, AmbidextroUS, Silver (Fbq800) - Behringer FX2000 - Stagg SMC6 6 metre standard microphone cable --- ## 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.pt/products/253528268-10-string-multi-effect-processor-ambidextrous-silver-fbq800](https://www.desertcart.pt/products/253528268-10-string-multi-effect-processor-ambidextrous-silver-fbq800) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-11-01*
