AudioControl THREE.2 In-dash equalizer

The AudioControl THREE.2 is actually a combination of an equalizer, preamp, crossover, and line driver. It’s there to take your digital signals and process them into crisp, clear sound and to limit and reduce background noise or “crackling” tones that simply interfere with a good sound system.

It lets you fine-tune to your musical preferences with 3 band EQ (+/-12 dB at 125, 1,250, and 10,000 Hz ) and one bass EQ: +/-12 dB at 40-80 Hz. It offers a brilliant ability to fight feedback, allowing the listening time in your car to be an enjoyable one.

This digital equalizer also has high-pass and low-pass crossovers, for controlling front and rear line outputs. Or when you do not use a subwoofer, the crossover can be bypassed, sending signals to the front and rear outputs.

Another great thing is the line driver which you can use to optimize noise ratio and dynamic range.

Biven all these specs we believe the AudioControl THREE.2 is the best car audio equalizer of the bunch if you can afford it because it comes with a premium price.

What is Car Equalizer?

A car equalizer (EQ) can help improve the quality of sound coming from your car radio by dealing with the things that can disrupt the audio.

The factors can vary varying, as your music could be drowned out by the wind from outside, the interior of the car (like metal grills over the speakers), or just general street noise.

The glass windows can cause music to also sound like an echo, but an EQ can cut tones or boost them to stop this issue from taking place. One same note can sound like something entirely different depending on what you’re using to listen with or where you are.

An EQ can give you specific adjustment ability over the quality of tone that is being emitted from your radio speakers.

Most car EQs come with two bands: bass and treble, but there can be five, ten, or even thirteen bands meaning the EQ is more detailed to your favorite sound.

For music equipment used by professionals, there can even be up to thirty bands, just to put into perspective how finely tuned you can really make audio. For most, a simple altering for a deeper bass or sharper treble is all they need to enjoy their music, while others may like to have all those extra options to fit audio to their strict liking.

The left side of the EQ is for low frequencies while the right side is for the high ones adjusting the top EQ bands control how much treble you have, and the bottom bands control the bass.

All sliders on a car equalizer are usually centered on certain frequencies in Hertz (Hz). Sometimes you’ll have to have a basic understanding of the music you are listening to so that you can adjust your EQ correctly. For example, tracks that have vocals don’t use many lows, but rather mids and highs.

What’s The Difference Between An Equalizer And A Crossover?

Well, an EQ compensates for the inconsistencies in a car by using different bands and changing the amplitude of audio signals at certain frequencies. They essentially are software filters that adjust how loud certain frequencies are.

A crossover takes in one input signal and splits it into two or three output signals containing separated bands of low-, mid, and high-range frequencies. These different bands feed into different speakers – or “drivers” – in sound systems: woofers, tweeters, and subwoofers (15-inch or 10-inch).

A simple crossover will have two filters: a low-pass and a high-pass, but this can increase depending on which one you use. The low-pass filter will only allow signals that are below a specific frequency, driving the mid-range driver to the woofer.

As you’ve guessed, the high-pass filter then only allows high-frequency signals, which feed through to the tweeter.

And finally, low-bass frequencies are directed to the subwoofers. Through a crossover, each speaker will only handle the frequencies that it can emit efficiently, that way there is no overlapping, high distortion, or overall mixing of noncorresponding tones, while an equalizer will take care of frequencies that need to be heightened or lessened.

There are two different types of crossovers: passive and active.

Passive crossovers do not need external power supplies, are easier to install, and will filter an audio signal after amplification.

But active crossovers do require a power supply, giving you more control over your sound and filtering audio signals before amplification. All speakers have their own frequency range that they perform best at, so a crossover will give them clarity, and just like an EQ, the more bands the more complex the sound adjusting is for you as the listener.

How To Properly Adjust The Car Equalizer?

Car equalizers have controls that offer a selection of presets: rock, concert, pop, vocals, concert, flat, electronic, jazz, acoustic and more, but it is not limited to just these ones.

Every person has a subjective taste in sound as well as the fact different speakers require different settings, so it is in the hands of the user to make sure it’s adjusted to the best of standards.

Start off by making sure the EQ is set at neutral (0 positions), meaning there is no EQ curve. Then, while playing a sound that you’re familiar with, make small adjustments to the frequency controls.

Start with having the subwoofer off and then slowly turn up the output until you hit the spot you’re happy with. Some call it the “sweet spot” which essentially means it’s in a setting where the bass has kicked in nicely without overpowering anyone.

The positioning of your car speakers can also have an effect on how you want to alter the audio sound.

Bass blockers can be used if you have small front speakers to help with filtering lower frequencies. This allows the music to be ultimately clearer and even louder. If your speakers are in the back of your car then you can use the faders on your receiver to bring music more forward or further back (probably depending on who’s in the ride with you).

Remember that handling a car equalizer for the best-desired sound is about balance and amount. If you want more bass, you can turn down the treble and mid-range frequencies.

What about a clearer treble? You can reduce the low frequencies to clear it up a bit. It’s best to cut and lessen instead of increasing, for this may lead to distortion of sound, which won’t sound nice at all.

How To Connect Car Equalizer To An Amplifier

To connect your EQ straight to your 4-channel amplifier, there need to be preamp-in and preamp-out channels on it, (which are usually located at the rear).

  • You will need two RCA cables to run signals to and from your EQ to your amp, (right channel jacks will normally take the red RCA plugs while the left is for the white or black).
  • Connect one pair to the preamp-in channels on your EQ and then connect the other end to the preamp-out channels on the amp.
  • Now connect the second pair of RCA cables to the preamp-in on your amp and to the preamp-out on your EQ. This will be between the amplifier and the receiver. Also, instead of preamp connections, some have “tape monitor channels” which work also.
  • Some amps have switches that will turn on the preamp connections. If you only have access to tape monitor channels, then you can turn this switch on instead.
  • Finally, turn on the EQ, the amplifier, and the receiver and adjust the EQ to your liking! Small changes can make a big difference, so start off slow and give it several seconds for the adjustments to fully take place.
