Equalizer Specifications

Type of Equalizer
This determines the way the equalizer processes the signal from the source unit. A parametric equalizer allows to you adjust the center point of the frequency band you are adjusting as well the bandwidth which can be narrowed or widened. A graphic equalizer has fixed frequency bands and bandwidth and only the frequency bands can be adjusted. A digital equalizer uses a software program to tune your system.
A graphic equalizer typically has more adjustable bands and is less expensive, whereas a parametric will have fewer bands but offer a greater level of control and provide more tuning options. Digital equalizers will tune your system with the most detail and precision but require a computer and are typically a little higher in price.
Parametric
Equalizer Bands
The number of graphic or parametric equalizer bands the receiver has. The better the EQ, the more likely you will be able to "tweak" your sounds to your desire.
7 band
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-Pass (LP)
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.

Display Color
The display color refers to the color of the text and or graphics on the receiver.

Variable-Color: The display colors can be changed by the user. If the default color of text/display is blue for example, the user can change the settings to where the color turns to red. Variable color displays are typically described in detail in the item's description.

TFT-LCD Display: In-dash receivers with a video screen that display multiple colors and often times video such as DVD, navigation or other video sources.

Great device!!

February 15, 2015

I used this as a line driver/Eq to replace my existing Pioneer head unit in my 97 Ford Ranger. I hooked it up to a Home Audio Bluetooth receiver and an Aux input jack to pipe music into this unit. The sound quality and usability of this setup is AMAZING!! Definitely one of the better purchases that I've made in some time!!
The only gripes I have are minor ones... The main volume knob could be a little bigger, there is no real way to know what the subsonic frequency is set at and the blue backlighting is WAY too bright!!!
Other than those little things, it's a great unit and I would definitely recommend it!!!

This eq is a lot nicer than most,it's more like having a 14 band instead of 7.with 7 bands of tonal change,and 7 bands of 12db plus or cut to that frequency. If your looking for sound quality this is it.the last 7 band eq you will ever need. Perfect for your dash.

good eq for the money

August 19, 2016

it was between this eq and the american bass but i decided to go with this model because it had a built in volt meter and i was able to find the specs as compare to the AB. im using it in my ice cooler boombox and it made a heck of a difference in sound.. i dont have to custom build my own crossovers to get the sound i wanted. What i like about this unit and other reviewer have mention is that they send you a small flat head screw driver to dial in the frequencies that you need to boost and it displays it in the small screen as well as the volts of your battery which i dont have to use a seperate volt meter. i migjt hook it up in my car too see the diference

great eq for the money

May 6, 2016

I got this to have some tuning options for my system. I'm able to dial up or down problem areas in my vehicle as this is a parametric. It's only a seven band but tunes like a 31 band third octave would. Very flexible and easy to use. I like the digital volt meter on the front panel. The display also shows what frequency is being adjusted. Three sets of outputs with gain control. Blue led backlight. Sub volume. No noise from this unit. Nice and clean sound. Solid build quality as well. Very happy with this unit. Getting one for my other car.

Great eq for the money

March 6, 2016

I purchased this product because of the flexibility in selecting the 7 frequencies you want, as well as the adjustable sub sonic filter for your subwoofer . Plus, this eq didn't limit you on a sub crossover frequency like others in its price range. I forgot to mention that the digital volt meter is a great touch as well. The blue back light is very bright, but doesn't bother me since I have it mounted in the center console armrest, but it could be a distraction if you dash mount it. Not sure about durability yet since I've only had it installed for a couple of weeks, but the fit and finish is well made.

Parametric, never had an EQ with it, wanted to check it out.
Richard L on May 22, 2016
I chose it because it has voltage meter
Alex H on May 13, 2015
The advertisement or the people don't mention anything about the power in watts that it adds to a system.Why not?
A shopper on Sep 4, 2015
Best Answer: This is a passive parametric equilizer. Passive no power. Does a great job of enabling you to contour sound in your vehical so it does sound louder. Its just not adding any true watts.

Which option provides the best sound quality:
1. Using the LFE and low pass filter function of the head unit that has separate RCA out for sub?
2. Using the low pass filter in this unit?
A shopper on Feb 28, 2015
Best Answer: That depends on a lot of factors...
What head unit are you using? What Amp are you using?...
I used the LPF on this unit to fine tune the sub amp because the settings can be adjusted without access to the amp... after getting a better idea what frequencies I wanted to set the LPF at I used the LPF on the amp because it was a better crossover(2nd order vs. 1st order). I hope this helps!!!
Regards,
John

Does the bass and low bands only control rear channel or is it also for subwoofer?
A shopper on Jul 29, 2016
Best Answer: No it controls all channels. Front/rear/sub depending on where you set your frequency points for the corresponding bass and low dials. Also depends on your crossover points. But to answer your question it will affect all channels.
