AudioControl Store

For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. “Can you really win without AudioControl”, was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products “make good stereo sound better”


The AudioControl EQL - 2 Channel Trunk-Mount 13 Band Equalizer

The EQL works wonders with any 2 channel audio system: From existing factory installed setups to custom audiophile-grade systems. Level-matching circuitry allows connection to either preamp-level or speaker-level inputs. The EQL also features thirteen-band, dual-bandwidth equalization and a Programmable Frequency Match (PFM) filter for precise bass control.

Key Features:

Dual Bandwidth Equalizer – 13 bands:

The dual bandwidth design of the EQL concentrates more control in the lower bass frequencies where the interior of an automobile causes problems. The higher frequency controls are spaced on octave centers to give you complete control up to 16,000 Hz. No simple dash-mount equalizer gives you this kind of flexibility.

Level Matching:

True standards in car stereo are hard to find. Every manufacturer has a slightly different interpretation of things. The input and output level controls on the EQL bring everything together. Now any head unit can be connected to any amplifier and the will system sound great.

Balanced Input:

The EQL takes noise rejection a step further than the average by incorporating balanced differential input circuitry. By looking at the output from your source unit in a different way the EQL can reject up to 60 dB of radiated noise.

Programmable Frequency Match Filter:

AudioControl's Programmable Frequency Match (PFM) filter system brings out the best in any system. A modular programmable low-cut frequency filter allows the system installer to easily customize the bass roll-off to match any speaker design. Unruly subwoofer boxes can finally be brought under control.

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.
Graphic
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.
13 band
Equalizer Frequencies
The frequency range that allows control of the center frequency of each equalization band.
31.5 - 16,000 Hz
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.

None
Built-in Bass Reconstruction
Bass reconstructors, or bass enhancers, improve low frequency reproduction in a car audio system with at least one subwoofer. These bass expander products will help your subs produce accurate bass thumps.
No
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
No
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.
Yes
Total Number of Inputs
This is the total number of input connections that go into the unit.
2
Total Number of Outputs
This is the total number of output connections that the unit will produce.
1
Button Color
Refers to the color of the physical buttons on the unit.
Black
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
7.5Vrms
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 - 20,000 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.
0.005%
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.

EQL Review

January 4, 2015

Pros: Very solid product. Well built, 13 bands of adjustability. Easy to install and adjust to your personal preferences.
Cons: It would be great to be able to make system adjustments without having to remove the top panel, Plus it would be a bonus to have included a second set of high input signal connectors to be summed.

Equalisers

November 14, 2011

Ever since i bought an MA audio 15 band equalizer from Sonic Electronix couple years back (i still wish they can bring it back) i can no longer be satisfied with using an in dash equaliser because there is not enough settings on them for me. This audiocontrol EQ has the best sound quality i have ever heard from any equalizer. The only difference is that the MA audio had 15 bands of eqalisation for both the front and the rear for around the same price range, so i have to buy another audiocontrol eqaliser to do the same work. Would i switch bak to the MA equalizer? No!! Not with the sound quality i am getting from this equalizer. Best sounding equaliser i have ever heard!!

Of course, another awesome product from audiocontrol

April 23, 2009

I have this unit in my 2000 ford ranger hooked up before a 24xs, and I have to say, this thing is amazing. I finally get the crisp clear sound from all my JL audio speakers that I should at the price I paid. All I had to do was tweak down the harsh frequencies 3 db at 2khz and 4khz and down the midbass at 125hz and that was it. Another great unit by audiocontrol and I greatly recommend it.
