What Are The Best Car Audio Equalizer Settings?

Table of Contents

If you don’t know what you’re doing, tuning your automobile sound system with an equaliser can be a maddening mess and a waste of time. To make problems worse, there is a scarcity of useful information. I’d be delighted to assist in the cleanup!

The truth is that there is no such thing as a “perfect” equalisation or audio system setting. It depends on your objectives, but the ideal settings are those that allow you to customise the sound in a way that most pleases your ears. I do, however, have some general equalisation suggestions that may be of assistance to you. After describing why an equaliser (EQ) is so useful and the issues with speaker sound, I’ll make sure to cover those in a separate section below.

If you really want to appreciate your music to its greatest capacity, your car’s sound system will constantly need to be improved. I’ll go over them in detail, as well as the EQ settings you’ll need to correct them. But first, let’s take a closer look at what equalisers are and how they function.

Equalizers let you enhance the sound of a speaker system by boosting or chopping ranges of sound as wanted the place they’re missing or have “peaks” (an excessive amount of volume). The aim is “smoothing” the sound to take away harshness or an absence of bass, for instance.

Ultimately although, they’re additionally an effective way to regulate the sound to your liking. Equalizers let you right issues with a sound system in car audio by boosting (rising the volume of) or chopping (decreasing the volume of) small sections (limited-width segments) of sound within the range of musical sound frequencies. These specifics “sections” are mounted round a central level referred to as the middle frequency.

In an ideal world, speakers would produce a wonderfully flat sound output with no dips or harshness within the sound you hear. That’s inconceivable and there are at all times areas the place the sound can use enhancements. The primary bass and treble controls included with many head models can’t right a lot, sadly. Fortunately, an equalizer lets us right many of those issues.

Equalizer bands and increase or lower (attenuation)

Equalizers cut up up sound adjustment into small “bands” of sound frequencies centered round a single frequency. The quantity of bands (quantity of adjustment slots if you’ll) accessible determines how a lot control you have got. The extra bands, the finer and higher the enhancements you may make. The quantity of increase or attenuation you’ll be able to apply is measured in decibels (dB) and often there’s a most range of +/-9dB to +/-18dB.

However, it will depend on the actual model and design. 9dB and 12dB EQs are quite common. The variety of bands an EQ has will increase the quantity of control you have got over the audio sound adjustment range. More bands present a way for higher sound adjustment (you’ll be capable of higher right speaker sound issues when tuning). A 31-band EQ, for instance, provides numerous audio control however take can take numerous time to tune a system. When selecting a extra primary equalizer vs one with extra bands, the best choice is the one with extra bands

How does an equalizer work?

Equalizers work by dividing up the total range of sound into smaller sections referred to as bands. These are centered across the EQ middle frequencies. This part of sound is then elevated or decreased as you want to regulate the sound.

The bands are then recombined and output as a full range once more with the EQ changes included. Equalizers work by taking the full-range sound of every stereo channel (or mono, if it’s a subwoofer crossover, for instance) and dividing them into “bands” utilizing filters. Each filter directs the sound frequencies of that band, primarily based across the band frequency, to a circuit that will increase or decreases the volume of that range relying in your changes.

The sound from every of these circuits is then mixed again collectively and despatched out to your amplifier or speaker system. The finish end result is identical input sound however with EQ changes utilized to it – not only a easy bass and treble enchancment!

Some equalizers use a single set of controls for each of the entrance and rear speakers (one set of EQ controls for each stereo channels) whereas others have separate left and proper channels for higher tuning. Some present EQ channels for each entrance and rear speakers. In some cases, one other smaller set of bands for subwoofer bass tuning is offered. This is commonly the case for digital equalizers like these in touchscreen car stereos.

Analog vs digital equalizers

Analog equalizers use digital {hardware} resembling op-amps, resistors, or built-in circuits to regulate the sound output as you regulate it. Digital equalizers (in most cases) are completely different in that they do that in software program utilizing mathematical software program routines.

While each have their professionals and cons, digital equalizers supply extra features nowadays and lower your expenses since and area since they don’t want the added {hardware} to do the work. In many cases in addition they embrace adjustable crossovers that make system adjustment even higher.

Basic really useful car equalizer settings – setting your EQ by ear

In this part, I’ll share with you some primary steps and EQ settings when doing it by ear. In the part after this I’ll go into the best means to take action: by tuning your system utilizing the best tools.

Note that tuning audio in car methods by ear is extra for correcting simply the obvious issues you’ll be able to hear simply. To actually know what’s happening along with your system, you’ll want the best tools and method I’ll share within the sound system car tuning information below.

Getting began with the fundamentals

You’ll need to do a number of issues earlier than making an attempt to regulate an equalizer as a result of having too many changes means they’ll work towards one another, that means you won’t get anyplace! My recommendation is to do the next earlier than adjusting an EQ:

Disable any particular audio modes like bass increase or “musical enhancement.” Turn the bass increase, if current, to “flat” or off.
Set the equalizer band changes all to flat. That is, to 0dB degree, in the course of the equalizer display (or to 0dB if it makes use of a quantity type control).

For many speaker methods (for instance factory speakers with a factory-installed head unit), sometimes the sound is missing in 2 or extra areas:

Not sufficient bass
Too a lot mid range
Not sufficient treble (high frequency feels like cymbals and string devices)
Music has poor element and doesn’t sound just like the recording should

In this case, I like to recommend doing the next, being positive to use small increments of the equalizer and make modifications slowly whereas listening fastidiously.

Increase the bass a bit within the low-end range. This can be a band with a frequency of 60Hz or near it – this will depend on your explicit EQ. You can then improve it a bit within the band above it and listen to the outcomes (ex.: 120Hz band, which remains to be bass however on the decrease finish of mid range sound & vocals).
Increase the treble 6dB or so across the highest band on the higher finish of the EQ, then proceed rising by 3dB when you hear an enchancment. Continue till it sounds disagreeable to you, then lower again till it’s higher. This is often a band with 16KHz or comparable (some only go to 12KHz, which isn’t good, sadly). Treble could be a downside due to speaker placement being lower than excellent in autos together with poor high quality factory-installed speakers, too.
If you hear “harshness” and the vocals and devices in music sound like they’re grating in your nerves, you in all probability have to lower mid range sound. Start with a band round 1KHz and reduce by about 3dB and pay attention for enchancment. If there isn’t any, set it again to 0, then transfer as much as 2KHz, 4KHz, and so forth as wanted.

Note: I like to recommend utilizing a music take a look at observe to do that. You should buy audio take a look at tracks for obtain or CDs to purchase on-line. Alternatively, you should utilize a music you recognize extraordinarily well that you simply’ve heard on a high-fidelity system earlier than. The thought is to know the way the music should sound with every little thing arrange correctly and decide your EQ settings by ear utilizing take a look at music.

Our ears are most delicate within the midrange span of sounds in order that’s typically one of many greatest downside areas of speakers that want consideration. Tweeters very typically want some improve on the high finish, too.

It’s an enormous downside with factory-installed tweeters which have a poor response (sound output) on the highest finish of the sound range. It’s additionally a typical subject since many car tweeters are mounted in a location the place they’re pointing away from you. That’s as a result of tweeters are best with a directional set up the place they’re dealing with your ears (referred to as “on-axis”) and to not the side or away from them. If not, you’ll hear get a reasonably high loss within the treble range in music.

How to tune your system for the best EQ settings

Some examples of your choices for measuring and tuning your car audio speaker system. Of the three, utilizing a laptop and RTA software program or smartphone app are the best values for the greenback. Today’s smartphone apps like AudioTool supply most of the similar features as rather more costly choices. As I discussed earlier, without query the best technique to tune your system (discover the optimum equalizer settings) is to make use of a measurement tool and discover the areas that wanted adjusting.

To achieve this, you’ll want a real-time analyzer (RTA) and microphone. There’s merely NO WAY to get the best sound utilizing only some music and adjusting it by ear. In the previous this use to be a critical ache within the neck – when you might even in any respect discover an RTA to make use of. Until some years in the past, real-time analyzers had been far too uncommon and costly.

A dedicated portable unit just like the AudioManagement SA-3050, for instance, typically offered for $1,500. They had been heavy, restricted in capabilities, and battery power wasn’t even commonplace! Thankfully, nowadays you will discover get skilled outcomes utilizing your laptop and RTA software program (resembling TrueRTA, for instance) or use an RTA app along with your Apple or Android cellphone. Of the 2, probably the most inexpensive and handy choice is to make use of your smartphone. For the sake of maintaining issues easy,

I’ll cowl utilizing a smartphone and an RTA app. I like to recommend AudioTool for Android because it’s very good and whereas it’s not free, it’s low-cost!

Using a smartphone app for tuning isn’t as correct as say a way more superior (and expensive) real-time analyzer tool setup. However, you’ll nonetheless get fairly good measurements and outcomes you’ll get pleasure from when you use it correctly.

Using an RTA app for tuning (and why you want a good microphone)

Although you should utilize your smartphone’s built-in microphone to get you by, I don’t advocate it for tuning your equalizer/sound system. Built-in mics have poor frequency measurement efficiency in comparison with an actual take a look at microphone. Calibrated microphones additionally embrace a file to permit them to present a near-perfect measurement in case your RTA helps it. While you should utilize your smartphone’s built-in microphone with an RTA app to tune your system and set your EQ, I don’t advocate it. They’re poor for measuring sound and your readings can be off – means off in some cases!

You’re a lot better off shopping for an inexpensive calibrated microphone like the Dayton Audio iMM-6 at about $17. Each one features a distinctive calibration file that can assist you get extra correct readings. You don’t have to make use of calibration (the mic is already fairly good) however it’s free, so why not get probably the most out of it?

How to tune a car equalizer

Your aim should be to not get good sound however to right the areas the place the speakers have unhealthy peaks or valleys within the sound output. For that, you’ll need dearer tools and much more time and effort. The most necessary factor is to have a reasonably good thought of what’s happening with the sound output and proper probably the most troublesome sound factors. To tune your system and measure the place it is advisable to make enhancements utilizing your EQ, you’ll need to do the next:

1. Park your car in a quiet space without outdoors noise that may intrude along with your measurements. Leave the car engine off.
2. Set up your RTA to an “octave” mode much like the variety of bands in your EQ. Set the measuring speed to medium or gradual. I personally favor 1/3 octave (31 bands) mode however for these of you with fewer EQ bands, setting it to a smaller variety of bands for the RTA display should assist.
3. Set your equalizer to all-flat (all settings at zero), bass increase OFF, and every other sound enhancement disabled.
4. For methods utilizing amplifiers, ensure you’re not utilizing a bass increase for the subwoofers.
5. With the RTA working and your microphone connected (arrange the RTA’s mic choice if wanted), play a pink noise test track for measuring the system’s sound output with the RTA. (You can use an audio file or CD, however it must be high-quality and never compressed audio to ensure you’re producing actual pink noise that’s not altered and that would end in unhealthy measurements.) Note that some RTA apps can generate noise so you’ll be able to join the output to the AUX input of some head models.
6. With the RTA working and held in a center place between the seats close to ear degree, be aware areas the place there are dips and peaks in your system’s response.
7. Begin adjusting the EQ a small quantity for the bands in these spots and punctiliously watch the modifications. Turning the EQ up or down an excessive amount of for every frequency may cause you to need to continually compensate by altering different bands as they work together. Do it a bit at a time.
8. A near-perfectly tuned system would seem as a virtually flat RTA line throughout your complete audio range. However, that’s not real looking. We’re aiming to get as shut as we will to that then make customized changes later.
9. Once you’re happy you’ve bought it corrected (it takes a little bit of time and endurance!), save your EQ settings as a preset if it’s a digital equalizer. For analog (dial or slider type EQs) models, take notes for future reference.
10. Final touches: play a music observe (with good bass) that you simply’re VERY aware of and know the sound on a correct system. Carefully make modifications as it is advisable to for what sounds best to you. In my expertise, that is rising the low-end bass (round 60Hz), decrease midrange (round 120Hz), and better frequencies (16 to 20KHz) relying in your listening to and style.

The best aim isn’t to get good sound however as a substitute (1) right the worst issues in your sound system and (2) regulate the outcomes to get the sound that YOU actually get pleasure from along with your music. After tuning the system, be at liberty to make use of bass increase or different features when you suppose you want how they sound. However, remember that a correctly tuned system with good speaker efficiency usually doesn’t want a bass increase or gimmicks to make it sound correct.
