A Cure for "One-Size-Fits-All!"

There’s simply no such thing as a “one-size-fits-all” audio system. To enjoy your system to the fullest, it needs to be tuned and tailored to not only your specific tastes, but also to suit the acoustic characteristics of the listening environment. With this in mind, we designed the NVX XEQ7, a 7-Band Stereo Equalizer that allows you to compensate for seven acoustic anomalies unique to the automotive environment. Each frequency band can be boosted or cut by up to 12dB, while a separate subwoofer volume control can boost/cut the subwoofer frequencies by 15dB. In addition to the equalization functions, the XEQ7 also features both RCA and mini-jack auxiliary inputs, allowing you to play audio from an iPod, MP3 player, DVD player, or other device. The front panel includes master volume and fader controls for easy adjustability.


XEQ7 Features:

  • 7-Band Graphic Equalizer with Dual Aux Input
  • Gold-plated contacts for optimum signal transfer
  • Master and subwoofer volume control
  • 3 Sets preamp outputs (front, rear and subwoofer)
  • 7V Max preamp outputs
  • Subwoofer frequency and level controls
  • Gold-plated RCA level inputs
  • Left and right gain adjustments
  • 2 Pairs of RCA inputs
  • One 3.5mm auxiliary input
  • Blue illumination
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

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.
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)
High-Pass (HP)
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Display Color
The display color refers to the color of the text and or graphics on the receiver.

Multi-Color: When more than one color is on the display, for example one part of the text is white, while the other part is blue.

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.

Signal Boost/Cut
The available signal boost or cut for each of the frequency bands.
12 dB
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
7 volts
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
10 - 50,000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
100 dB
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

Wesley T on Oct 18, 2015
In order to use input 1 and 2 on the back i have to access the top of the EQ and flip the switch? If so, i don't understand how both inputs are usable once the unit is installed. I understand there's also an input on the front that is auto. But the rear is not?
jr j on Apr 9, 2015
Best Answer: if your head unit has a ft and rear output connect both of those to the ft and rear inputs on the rear of the eq.then use both outputs on the eq to go too a four channel amp,or two one channel amps.i think the switch is for if you have only one output on your hear unit,use switch to get two outputs off eq.input on ft is for a phone or ipod.it will bypass your head unit .then you can use volume knob on eq for power.i really like mine.works well.use low pass switch on eq to get best responce and sound.i set it to 120hz and system really came to life.get and blow your doors off.good luck!

Hi I have a JVC kd-avx33 head unit.

I dont use the internal amplifier, my speakers (jbl ms-62c and jbl t696) are powered by a jbl gto1004.

I'm looking for those 1/2 din equalizer.
The internal equalizer of the head unit does the job but i'm looking for something more efficient.

Would you suggest me this equalizer i'm not totaly on a budget but i dont want to spend 200 on an equalizer?
dude d on Aug 11, 2014
Best Answer: This equalizer is exactly what you want. It's simple to set up and gets the job done. My only complain would be the knobs, but you get used to them. Don't spend 200 on an eq. The nvx is perfect. Make sure your amplifier is 4 channel so you can use all the frequencies

Does this unit ABSOLUTELY have to battery hardwired, or can it be spliced into head unit 12v battery lead?
Steve C on Oct 4, 2014
Best Answer: It wouldn't ABSOLUTELY have to be wired to battery, but if your 12v lead is too thin it may pop a fuse by running both units on the same lead. Could be unsafe if it's really thin, if it's thick you'll be fine. This equilizer also boosts the signal outputs to the amp, so I would run another lead IMO

I need the speaker wires for this with the RCA connectors on one end (to plug into unit) and wire leads on the other end to splice into my auto's speaker wires. What would you suggest? Do you carry this product?
Steve C on Nov 12, 2014
Best Answer: Steve an EQ like this requires an external amplifier. It takes signal in allows you to manipulate the signal for your external amplifier to boost for your speakers. You cannot hook it up directly to your speakers. What you seek is similar to the MS-8

It has a built in amplifier so there is no additional equipment.

will a 4 channel amp and a monoblock amp both together work with this? and can you equalize all the channels separate? for instance I don't want my tweeters playing low frequencies and my mids playing high frequencies.
Isaac T on Sep 17, 2014
Best Answer: Well it will let you adjust the frequency for 7 bands I'm running ah 4channel Amp which controls my mids and highs. I'm also running ah 2channel Amp on my subs and it works fine if installed right you will be able to turn whatever frequency dwn or up just depends on what you like!!! Hope this was some help to you!!!!!!

If my head unit (Kenwood DNX572BH) has the 3 preamps out (Front, Rear and Sub) and this only has the 2 inputs how would I go about wiring this to the whole system? Or, is this just not what I need?
John - on May 28, 2015
Best Answer: You only need to plug in the front left and right or the rear left and right. The EQ will change it to stereo. Car stereo is not like a 5.1 home stereo, it doesn't break up the sound that way. I have a sony head unit set up in my car with this EQ, on the front channels only. The Bluetooth only seems to want to go through the front speakers on my head unit. This EQ sounds real good for the money.

Hi all. I purchased the NVX XEQ7. I have a 2014 ford fusion with all stock radio. Right now I have a PAC LOC 7 running my sub from my right speaker channel and it is fantastic and loud.
I bought the NVX xeq7 so I could add another 4 channel amp to my front and rears. I took the output RCA from the LOC and ran it to the INPUT 1 on the NVX... everything hooked up perfect. The only problem is that the VOLUME OUTPUT is SUPER SUPER LOW even after increasing the output levels on the NVX XEQ7.
Can anyone help me with this and let me know why? do I have a BAD NVX? I cannot imagine it should be like this?
Just for comparison, with ONLY the LOC installed (no nvx eq) my bass level could only be turned up to 1/2 and hitting 128 db. With the nvx eq I had to turn all levels up and I can barely hear the bass.
Or can i not use an LOC running to the EQ?
PS... just to see, I did run my right speaker into the HIGH INPUT wires on the NVX and the volume was still SUPER SUPER LOW....there was just a hiss with little music coming out of the front speakers and sub output was still very low. VERY WEIRD. Or I cannot run an EQ from an LOC.
OR I have a lemon eq...

Thank you,
scot m on Jul 18, 2016
Best Answer: Hi Scot,

I know you said you increased the output levels on the NVX, but to be clear, are you referring to the volume knob on the front, or the outputs on the top of the unit that requires a small screw driver to access? I ask because I had a similar issue when I purchased mine. I was sure that I turned up the output volumes but I didn't. I ended up returning the first unit and once I received the replacement I had the same low volume issues. I dug a little deeper and discovered the screwdriver was a tiny bit too large and what I thought was turning was not. In other words, make 100% sure you're turning up the levels with a small enough screwdriver.

Are the sub channels summed? Do they output stereo or mono?
A shopper on Mar 24, 2016
Best Answer: The XEQ7 does not sum the channels to create the bass channel.

The XEQ7 has an internal crossover that you can set to 60 or 90hz with the selector switch on the top of the unit. The XEQ7 output the bass in 2 chanels (R and L).

Hope this helps.

I have a 2014 f150 with my touch... can I run this after the factory amp to my 4 channel without a processor?
Gregg B on Aug 6, 2016
Best Answer: Usually with an EQ you want to run it AFTER the radio and BEFORE the amp.
As for if you need a processor, you say you have the factory amp, then YES you might need a processor or equivalent, like the LC6i or LC7. The of the LC6i and LC7 sum all the highs, mids and lows.
When you buy the oem upgraded stereo with amps from Ford, like what you have, it splits all the frequency's up. The LC6i or LC7 or processor with take all those split frequency's and SUM them into 1 full frequency and send them to the correct high, mid and sub outputs.
On Youtube, search " adding 4 channel amp to factory stereos" and " LC7 or processors".
You will find a lot of good info that explains how factory stereos split the frequency's and how the LC7/processors sums them back together. Hope this helps.

one question, it says the remote wire is a input/output, i understand what that means, but cant find a schematic for this because im wanting to wire mine a certain way, so can someone please explain like exactly what they mean you can use the remote wire for since it can be both a input and a output? thanks.
A shopper on May 28, 2016
Best Answer: Not sure why it is listed as input/output for the remote wire. This is just a standard setup. "1" always on batt. connection, one ground, one remote turn on... usually fed from the head unit's power antenna. In other words, it is an "in" of 12 volts. There is no "switch" to turn on the unit. 12 volt power on this remote lead is the switch. If you power up both the batt and remote at the same time,(tie them together) the unit may not turn on. (did this). Hook batt. to 12 volt constant supply. Then the remote wire will switch the unit on just fine.. Have had nice performance from this unit. The same wire from the head unit is usually run to the remote turn on wire of an amp.

do you to purchase additional RCA's for this ? how many would I need I run my coaxial's off my head unit and sub with a monoblock..RCA's needed ? How Many ? Thanks
Ron L on Jan 26, 2016
Best Answer: You will not need this unit if you are going to run your coax speaker off you HU. This is RCA in and RCA out. You run one set of RCA's from your HU to the EQ, then up to 3 set of RCA's from the EQ to your amplifiers. The amplifiers will then power your speakers.

were is the wiring diagram for the high input harness ?
A shopper on May 13, 2015
Best Answer: It's on the top right hand corner of the unit. You just splice into the factory front or rear speaker wires and the black wire is grounded to the car's chassis.

Hi all...A customer asked me a question via my email. I tried to answer but the link to answer would not work so I am answering through here instead.
Question was "I have a 2014 f150 with my touch... can I run this after the factory amp to my 4 channel without a processor?"
Did you mean after your factory "radio" to your 4 channel amp?
I wish you gave more info, because I do not know if you have factory or upgraded stereo with amps, but I will try to help.
Answer 1) Usually with an EQ you want to run it AFTER radio and BEFORE the amp because the EQ has all the outputs for your amps.
2) as for needing a processor, and you are running the EQ after the radio and before the amp, I am not 100% sure... but I do not think you need a processor if you no split frequency's. (highs from 1 amp, mids from another amp and bass from another amp).
3) Are connecting to the low inputs or the high inputs on the EQ?
4) if your original question is correct ...."I have a 2014 f150 with my touch... can I run this after the factory amp to my 4 channel without a processor?" I am wondering why you want to run an EQ between 2 amps? That is why I asked if you meant AFTER the oem radio?
If correct, then YES you may need a processor to sum all your highs, mids and bass frequency's into 1 or 2 full frequency outputs. Something like the LC6i or LC7 or equivalent will be needed to sum everything back together when ford split all the highs, mids and bass.
Sorry for the huge paragraph, just trying to answer to the fullest. Hope this helps.
