11 best graphic equalizer homes
A "graphic equalizer" in the context of car audio and home audio systems is a device used to adjust and fine-tune the frequency response of an audio signal. It allows users to control the relative levels of different frequency bands, often represented as sliders on a graphical display, hence the name "graphic equalizer." Here are some key points about graphic equalizers in homes and car audio systems:
Frequency Bands: A graphic equalizer typically divides the audio spectrum into multiple frequency bands. Each band is associated with a slider that can be adjusted to boost or cut the level of that specific frequency range. Common frequency bands include bass (low frequencies), midrange, and treble (high frequencies).
Equalization: The primary purpose of a graphic equalizer is to perform equalization, which involves altering the balance of frequencies in an audio signal. This allows users to customize the sound to their preferences or to compensate for acoustic characteristics of the listening environment.
Home Audio Systems: In home audio systems, graphic equalizers are often integrated into receivers, amplifiers, or standalone components.They are used to adjust the audio output from sources such as CD players, turntables, or streaming devices to match the acoustics of the room or personal listening preferences.
Car Audio Systems: In car audio systems, graphic equalizers are commonly found in car stereos and head units. They serve a similar purpose as home audio equalizers but are designed to enhance the audio experience within the confines of a vehicle. Car audio enthusiasts use graphic equalizers to optimize the sound for their specific car's interior.
Controls: Graphic equalizers typically have a series of sliders or knobs that correspond to different frequency bands. By moving these sliders up or down, users can boost or attenuate specific frequencies. Some modern equalizers may also include presets for common audio settings or automatic equalization features that analyze the audio environment and make adjustments accordingly.
Sound Quality: Properly configured graphic equalizers can improve the overall sound quality of audio systems by reducing resonances, enhancing clarity, and addressing any audio imbalances.
Advanced Features: Some graphic equalizers offer advanced features such as parametric equalization, which allows precise adjustment of specific frequencies and bandwidths. Additionally, digital equalizers may have presets or user-defined profiles for different music genres.
Installation: In car audio systems, graphic equalizers are typically installed by professionals or enthusiasts who understand audio tuning. Proper installation and calibration are essential for achieving the desired sound quality.
In summary, graphic equalizers are audio processing devices commonly used in both home and car audio systems. They provide users with the ability to adjust the levels of specific frequency bands to tailor the audio output to their preferences or to compensate for acoustic characteristics of the listening environment. Whether in a home or car, graphic equalizers can play a significant role in achieving optimal sound quality.

Ultra-Compact 9-Band Graphic Equalizer with FBQ
If we all lived in a perfect world, there would be no need for audio equalization. Sound systems would be perfect and would reproduce perfect signals in all their glorious perfection. Also, everyone in that perfect world would like the same amount of bass, midrange and high frequency, and there would be no such thing as feedback. But the world isn't perfect, is it? Even the best sound system can benefit from the use of a good EQ--like the FBQ800.

![]() Nine steps of graphic EQ. |
How Does it Work?
Imagine the frequency range of the sound you hear as a highway, a very wide one with nine lanes. Each of these "lanes" represents a single octave of the sonic spectrum. The first four lanes, labeled 63 - 500 (Hz) contain the really low frequency sound content, mainly bass, bass vocals, and the kick and tom drums. The three lanes labeled 1 k, 2 k and 4 k (Hz), make up the fundamental zone of most musical instruments and the male and female vocals. 8 k and 16 k cover the frequency range of cymbals, snare drums and higher pitched percussion instruments. The FBQ800 allows you to control the flow of audio traffic in each of these nine lanes. When properly applied, EQ makes it possible to hear all of these frequency ranges equally, thus the term equalization.
Feedback Elimination
When a specific frequency, or range of frequencies, reaches too high a level, feedback occurs--that all-too-familiar squeal or howl you get when the mic is too close to the speaker. Basically, feedback happens when there is so much of a particular frequency that it is picked up by the mic and run through the system again. That's why feedback typically gets louder and louder the longer it's allowed to occur. Needless to say, this kind of feedback is very undesirable.
This is where the FBQ800's Feedback Detection System really works its magic. In this ingenious circuitry, LEDs on the individual faders light up when that frequency band is approaching the danger zone. All you need do is lower the illuminated slider until the LED blinks out--voilá, feedback problem solved! What once required a highly trained ear is now an activity that even a child can master.
Sonic Toolkit
That really is the best way to describe the FBQ800. With its nine frequency bands, you easily fine-tune your sound and instantly eliminate feedback. And each fader can be used to boost or cut the frequency range it controls by as much as 12 dB (and that's a lot!).
Special attention is paid to the low frequency zone. In addition to low frequency faders, the FBQ800 features a Low Cut filter for removing unwanted low frequencies such as fl oor rumble, room resonance, electrical hum, etc. This is especially handy if your system is being used for speech rather than music.
To Boost or to Cut, That is the Question
Raising and lowering specific frequency bands can improve the frequency response of any room's acoustics. For instance, if the room you're in is "bass-heavy," lowering the 63 and 125 Hz faders can help eliminate an overall "boomy" or "muddy" sound. Likewise, gently boosting the 8 and 16 k sliders can add sparkle to a somewhat "dark" mix. Are the vocals getting lost in the mix? Raising the level of the 1 k slider can help bring them out.
It's important to note that raising a single fader level is not always the best solution; it's often better to lower the bands surrounding the frequency you want to bring out, and then boost the overall volume level to achieve better headroom.
Built for Accuracy and Reliability
Speaking of headroom, FBQ800's 6-digit LED Input/Output meters and level control are provided for precise level maintenance. Longterm reliability is ensured, thanks to high-quality illuminated faders and switches, and our ultra low-noise audio operational amplifiers provide outstanding sonic performance. In addition, all Mini Series components may be stacked to create an ultracompact signal processing solution.

User questions & answers
Question: | What type of cables are required to hook this up between an amplifier and yamaha receiver? Much appreciated |
Answer: | Both |
Question: | Can you adjust each channel (left/right) separately |
Answer: | Nope, the only things lit are the little indicator lights for power +/- 12dbs and something else. |
Question: | 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 |
Answer: | They are very clean sounding eqs. |
Question: | does it connect to amplifier |
Answer: | First, this is not a player. This is a tone control with instead of just the normal bass, treble and high, divides it into 31 (from 20HZ to 20KHZ). Also, this model is mono (1 channel). You can get 2 of these or get the stereo model. You still need an amplifier and a player. You hook this up between a like a CD player and your amp. |

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" |

User questions & answers
Question: | does it have 48v phantom for both XLR mic inputs |
Answer: | No. |
Question: | I have read this unit takes two racks spaces, albeit it states above it is 5.9 inches, so which is it? Thank you |
Answer: | Just measured, the height is 3.5 inches. |
Question: | Is this true?...i have been told that i cannot connect this to a onkyo 737 home theatre receiver because it does not have a tape loop |
Answer: | Hi Steve. I looked up the Onkyo 737 so I could answer your question intelligently. I need to know how you want to use the EQ before I an give you a good answer. You could use the Zone 2 output to feed the EQ input and then connect the EQ output to another source input, say if you own a tape deck and you want to equalize the response, but I do not see the traditional "tape loop" that would enable you to equalize the front two channels irregardless of which source you pick. So the simple answer is no you can't use it effectively. Sorry. |
Question: | whay are the in put / out put in each channel are crossing? like. rca has in put and out put on same channel |
Answer: | RCA is unbalanced, meaning its susceptible to noise problems. XLR (and 1/4 trs - not 1/4 tr) are balanced, and more immune to noise problems picked up in interconnecting audio equipment. Balanced connections use shielded, twisted-pair cable and three-conductor connectors (like XLR or TRS connectors). This noise cancellation is called âCommon Mode Rejection.â It's also good for long cable runs. And so XLR and TRS cables are used to transmit balanced audio from one balanced device to another. In an audio rack you might be tempted to use an inexpensive cable like RCA because the cable runs are short. That's your choice, but the professionals use XLR cables for the cleanest sound they can engineer. |

User questions & answers
Question: | are the sliders lighted |
Answer: | No, this is a single channel equalizer, if you bought 2, one for each channel it would work. But there is a better answer, the ART 341 is dual channel for stereo systems. However it comes with 15 band per channel, 2/3s octave. Better function in my estimation. And provided you have RCA input, mini-plug or 3 prong connections on your amp, going from CD to amp to eq to speakers is easy. This eq is by far the most versatile of the ART eqs. |
