13 best audio component equalizers

Audio component equalizers, commonly known as equalizers or EQs, are electronic devices or software tools used to adjust the frequency response of audio signals. They play a crucial role in shaping the tonal balance of audio systems, such as car audio systems and home stereos, to achieve the desired sound quality. Here's what you need to know about them:

  1. Functionality: Equalizers allow users to control the level of specific frequency bands in an audio signal. They can boost or attenuate certain frequencies to tailor the sound to their preferences or to compensate for the acoustic properties of the listening environment.

  2. Frequency Bands: Equalizers typically divide the audio spectrum into multiple frequency bands, often referred to as "bands" or "bands of equalization." Common bands include low (bass), midrange, and high (treble) frequencies.Some equalizers offer more precise control with parametric EQs, which allow adjustment of individual frequencies.

  3. Types of Equalizers:

    • Graphic Equalizers: These feature a set of sliders or knobs, each representing a specific frequency band. Users can adjust the level of each band to create a custom EQ curve.
    • Parametric Equalizers: Parametric EQs provide more control over the shape of the EQ curve. They allow adjustment of frequency, bandwidth (Q), and gain for each band.
    • Digital Equalizers: Often found in car audio systems, digital equalizers use digital signal processing to provide precise control over the audio signal. They may include presets for different music genres or room acoustics.
  4. Applications:

    • Car Audio: In car audio systems, equalizers are used to compensate for the limitations of the vehicle's acoustics and speaker placement. Users can fine-tune the audio to their liking, ensuring a more enjoyable listening experience during drives.
  5. Crossovers: Some equalizers include crossover functions that split the audio signal into different frequency ranges for individual speakers, such as woofers, midrange drivers, and tweeters. This helps optimize sound distribution and prevent distortion.

  6. Spectrum Analyzers: Some modern equalizers come with spectrum analyzers that provide real-time visual feedback of the audio signal's frequency distribution. This makes it easier for users to identify and adjust specific frequencies.

  7. Equalization Techniques: Equalization can be used for various purposes, including:

    • Tonal Correction: Balancing frequencies to achieve a flat response or to compensate for deficiencies in the audio system.
    • Room Acoustics: Adjusting EQ settings to account for the acoustic properties of the listening environment.
    • Sound Enhancement: Tailoring the sound to personal preferences by boosting or attenuating specific frequencies for a particular music genre or audio source.
  8. Installation: In car audio systems, equalizers are often installed between the head unit (stereo) and the amplifiers or directly integrated into the head unit. Proper tuning and calibration are essential for optimal results.

Equalizers are versatile tools for audio enthusiasts and professionals, allowing them to achieve the desired sound quality in various listening environments and settings.

User questions & answers

Question: How would you wire this to a head unit that has a front, rear and subwoofer channel? Would you only use the front and rear and toss the other set of r
Answer: So with only one input from the head unit does the eq convert it to front and rear sound? What I mean do you loose the rear sound or does it just double and split the front channel?
Question: Does this product light up
Answer: Yes it lights up blue cleaned up my audio very well
Question: Anyone els experiencing a popping noise when you take key out ignition if so any ideas on how i can stop it? I already tried grounding it to radio
Answer: Had the same issue with ankther brand EQ. Problem went away when I switched the positive from the EQ and attached it to the yellow cable straight to battery not the red to ignition. That should fix it.
Question: How would you do the power wire i see theres one in picture with a fuse but isint that to short
Answer: Hello, No the Red wire with fuse holder is not to short. The longer side of the Red wire goes to the Scar SKA7EQ, On Back of the SKA7EQ is the power, ground, and Remote terminal. The Red wire will be extended with a 14awg wire to your power source. Source could be the car battery, or an Accessory fuse circuit of 10 amps 12volts DC current. Extending this red wire is Normal in the audio installation world. The coupling will be needed to successfully butt the two wires together and crimp both sides, if u like install the double red wire size with Heat Shrink Tubbing, then Couple the wires with the "Butt Connector" , slide the heat shrink over it and heat the heat shrink with a Heat Gun, or powerfully hair dryer, then run the Red wire to the Accessory, or Battery positive Red Terminal. The same thing for the ground wire, black wire has no fuse in line so Run from your battery Negative Terminal Black, to the Scar SKA7EQ next to the Red wire, and Tighten it down to the SKA7EQ. The Remote wire is "In the business of Audio Installation" Traditionally Blue, Or Purple, Strip 4mm, or 3/8" and Install it into the Scar SKA7EQ at the R terminal, R stands for "Remote" or "Trigger" this Blue, Or Purple wire goes to your amplifier, and at the amplifier you will see a Positive terminal, a Negative Terminal and the R, "Remote" terminal the Blue or Purple Remote wire tightens onto the amp in the R terminal spot. The wire should be all 14 AWG for this. Wiring your amps u should at least use 4awg for both Power and Ground, Directly to the car/boat/atv Battery. Use small spools of OFC Copper, Red Positive, Black Negative, and Blue/Purple Remote from amazon, You have to have Amplifiers in your system to use the SKA7EQ. Get an Amplifier install kit, plus the three spools of 20ft of 14 AWG Red, Black, Blue from amazon....Good Luck.

User questions & answers

Question: does this item works with a Turntable because I have one and I cant seem to get it to work
Answer: This unit requires a compatible amp : receiver with Inputs and outputs to and from equalizer to amp. Basically you are running signal out of amp thru Equalizer and back into amp. Turntable should go into phono jack in amp, receiver. Very few new Receivers are able to accept equalizers. Older ones from the 1970’s are good. I had to buy a Yamaha R-S 700 receiver so everything would work. Contact me with any other questions. Good luck Michael
Question: Is hoked up through rca plugs
Answer: Yes
Question: Need instructions on wiring it all together
Answer: 1) 'Source' to EQ 'line in'. 2) EQ line out to receiver or amp. note: if multiple sources ie DVD, TV, B/T etc use a source switch for 'Source'. (like the TC-7240 4-way stereo lin router.)
Question: Can you run a cd player through this eq
Answer: Yes, but you will need an amp or receiver to power the output to make it audible...two ways to do it: 1) run the output from the CD player to the input of the Equalizer, and then the output from the equalizer to the amplifier/receiver - only the CD source will be "equalized" 2) run the output from the CD into the tape monitor input and then hook the tape monitor output to tape monitor input on an older style receiver (has to have tape monitor switch) , now all inputs to the amplifier /receiver will be "equalized"

PLEASE ANSWER BECAUSE TO ME AUDIO COMPONANTS SUFFER EXCESSIVE VIBRATION AND JOLTS AS WELL AS MOISTURE FROM SPILLS AND HUMIDITY. PLEASE ADVISE. I'M NOT THE ONLY CURIOUS BUYER OUT HERE! RIGHT BROTHERS AND SISTERS? THANX, TOM
Question: Is it for a car or home stereo
Answer: Car
Question: can this be used as home eq between tv and soundbar
Answer: Yes, it absolutely can be used between a sound bar and a TV. You will need to purchase a 12volt power supply, that is capable of at least 20 amps. And depending on how you get your sound to your sound bar, it can be put inline if you use the headphone out jack to a RCA's. Then you can input the sound directly into the EQ, then into the sound bar, if the sound bar allows for an RCA input from a source. I have several set ups like this in my house. I should probably write a tutorial on how to set this up as it is not expensive and I'm sure a lot of dudes would like more control over their sound. If you guys ask, I will create an article on this.

User questions & answers

Question: This one is 110v or 220v. or it can be used for both. why do i find the recording is 220v - 50hz - 30w
Answer: I'm not sure what your doing wrong. This EQ is set up with inputs and outputs that aren't laid out like regular stereo equipment. Inputs and outputs are not color coded and each channel is not marked left or right, but 1 & 2. Pick one side for you left and plug the input from your device (cd player, phone, etc) into it and run the output to one of your inputs on the amplifier, either left or right. Do the same for the other channel. I ended up marking L and R on the front of my EQ panel so I can adjust the stereo. Hope this helps.
Question: What voltage A.C input 120v or 230v
Answer: Assuming it is the amplifier which accepts or requires RCA cables, your idea should work if you only want the EQ effects for the iPad. Because the EQ341 is dual channel, you can also route another source to other channels if the amp/tuner has more than one (for example, CD, Phono, Aux, etc.).
Question: Does software come in English
Answer: It depends on whether you're looking at the front or rear of the equalizer. The channels aren't labeled "right" and "left" but rather "one and "two". If you want your left channel to be indicated on the left side of the front equalizer panel, use the inputs and outputs for channel one, which are on the "right" side of the rear panel.
Question: What’s the difference among the x5, s5 and the rev
Answer: The actual unit width is 19.0" including the mounting ears (non-removable). The body of the unit (not including the ears) is about 17.5" wide. The entire unit will tightly fit inside a 19" wide space. Not sure what the 21.5" is referencing.
Question: how do I hookup EQ to mixer using rca jacks? I am getting no signals
Answer: I don't get your question... sorry
Question: If i'm running from my i pad into the eq and then into my amp/tuner with rca cables which rca inputs do i use? thanks
Answer: It is not visibly one piece, but the handle tip is the same material as the blade. I appears one piece.
Question: The rca in's/outs i assume are left rca's=left channel - right rca's= right channel. i just bought this and the rca's are not color coded. correct
Answer: In general the difference between a utility knife and a boning knife is one of heft. A utility knife if generally thicker and meant for rougher work. They generally don't hold an edge as long. A boning knife is generally sharper and more flexible for work around the bone.
Question: I'm confused, says this is 19'' rack mount but description says 21.5''. I need this to fit into a 19'' non-rack space, will it fit
Answer: Yes, I put them on the magnetic knife holder.

Question: Can i put 4 of this speakers, 2 front, 2 rear, without amplifier, i have Opel Tigra with fabric speakers and radio
Answer: Dear,our software come in Chinese and English.Is very easy to operate.
Question: Do these have crossovers
Answer: Dear, X5 and S5 are the same effectors, but their models are different. Our effectors are regulated by anti-howling, equalization and reverberation. The microphone has 15-segment equalization and the music has 7-segment equalization, which is very powerful. It can also be controlled by computer. X5/S5 is a digital effector and can be controlled by computer. The rev3900 is analog, mainly for panel adjustment. Audio processing is also directly adjusted by several knobs on the panel, and the cost performance is better by X5. The main difference is that one is digital and the other is analog. These two models are our best sellers. If you have any questions, welcome to consult us by email. Thank you!

User questions & answers

Question: Will this work with denon avr 2112ci receiver
Answer: Yes you can. I only use 2 channel receivers. Not into cinema and avr receivers. I use an external audio source selector. Available on Amazon. Mine handles 3 sources. But selectors with more source inputs are available. I run my sources to the inputs on the selector. Then run the single output to the auxiliary input or in the case of newer receivers, input 1,2 or 3. For my application it works very well. Technically you can connect this eq to your Denon or any other receiver without the in out loop.
Question: what would cause this to make an awfull hissing sound ? right now its useless
Answer: Trying to diagnose sound equipment is not always easy. A hum usually means a bad ground. A his could be a lose connection or a bad cable. First see if the noise is on both sides or just one. Single side noise try changing a cable from the left to the right to see if the hiss changes sides. If it does change does change out the cable. If the his stays then you have a speaker problem. If the his is on both sides check your ground. Hope this helps.

Product Highlights: Most equalizers used for live sound mixing will allow you to affect frequencies across a variable frequency range. In general, if you’re trying to tune a sound by emphasizing desirable frequencies or pulling back less important frequencies, then you’ll be better off keeping the bandwidth fairly broad. On the other hand, if you’re trying to notch out hum, tame hiss, or carve out some other unwanted sound, then you’ll preserve your overall sound better by narrowing in on the frequencies you want to remove. Once you get into the world of digital mixers, studio-style fully parametric EQs become more common. These equalizers not only allow you to adjust the center frequencies of the mid bands, but they also allow you to dial in the bandwidth to make precise alterations to your sound, boosting board frequency ranges for added warmth or notching out an annoying resonance at 1.5kHz. While this surgical precision can be incredibly useful, it’s important not to get mired in minutia that can take up time you simply don’t have in live music production.
