EQ on Steroids

If you want great sound and love to “tweak” your system, then you will truly appreciate the AudioControl THREE.2. Affectionately called the "EQ on steroids", the THREE.2 is a high-end pre-amplifier that offers equalization and crossover controls for enhanced sound quality. Multiple audio inputs, both front and rear allow for maximum connectivity with all of your favorite source units.

Endless Features

While being housed in a compact 1/2 DIN sized chassis, the THREE.2 is truly a feature-laden processor. The THREE.2 starts with four stereo equalization filters including AudioControl’s proprietary Para-BASS controls, which give subwoofers extra kick and detail as needed. It also features a 4 channel, 2-way, 24 dB/octave car audio crossover with a fader. To round out the package the THREE.2 also includes a subwoofer level control, master volume control, and the ability to select the back lighting illumination color between Cool Blue and Hot Red.

Ease of Installation

Given that many of today’s audio enthusiasts like to carry their music with them, the THREE.2 is equipped with dual, 3.5mm auxiliary input jacks located on the front and rear of the chassis. This helps facilitate the permanent installation of cabling or lets a user plug in their portable audio device on the fly.

General Features:

  • In-dash Pre-Amp controller
  • Dual stereo auxiliary inputs (3.5 mm front and rear) for easy connectivity of portable audio devices like iPods
  • Two input channels and two, four, or six channels of output
  • Stereo and Para-BASS equalization controls for maximum sound quality
  • Precise 24 dB/octave electronic crossover plus subwoofer level control optimizes bass performance
  • Pre-amp line driver (13 volt peak) delivers maximum signals to amplifiers
  • Master volume control and fader
  • Selectable illumination – Cool Blue or Hot Red LED’s
  • Compact 1/2 DIN chassis
  • Authorized Internet Dealer
  • 5 Year Manufacturer's Warranty (*when installed by an authorized AudioControl dealer)

Equalizer Specifications

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.
3 band
Equalizer Frequencies
The frequency range that allows control of the center frequency of each equalization band.
20 - 20,000 Hz
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.
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.
Button Color
Refers to the color of the physical buttons on the unit.
Blue or Red
Signal Boost/Cut
The available signal boost or cut for each of the frequency bands.
24 dB
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
13 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).
20 - 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.
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.
110 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.

Flexible Pre Amp - Line Driver - XOver

September 2, 2013

Only requires Front Two Channels for input from the source unit then has Front, Rear and Sub Woofer Left & Right outputs. The Sub Woofer output includes an electric (active 24 dB) crossover at 90 HZ and can be changed out to 30 HZ - 3500 HZ or can by-passed. Line Driver up to 13 v and two 1/8 Aux. plugs, one on the front and one on the back for Ipod or other devices. I use this pre amp along with the Audio Control 6XS for a 4-way active crossover system.

Much control for no much $$$

June 24, 2013

I recently installed this unit in my Dodge Challenger. I have used many AudioControl products in the past but had never used this particular "in dash" piece. Let me tell you, it gives you a very good command of whatever music you are listening too. The adjustments are very accurate and the master volume control is a great feature. The sub control and gain control are great as well. You will not be disappointed with this EQ. Pair it with the in dash Epicenter and your subs will do more than you ever imagined.
