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.
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.

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.

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.
