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.
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.
12 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.

High-Pass (HP)
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.
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
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.

Great addition to my Alpine iDA-X305

June 9, 2009

Pretty much a must-buy is you care about sound quality. Too be honest, if you spent the cash on one of the higher-end units like the X001, X100 or newer X305, you should automatically pick this up with it. Makes a HUGE difference in the type of sound you can output from the headunit. I previously owned (and loved) a Sony MEX-BT5100, the only Sony headunit with extensive EQ features, but this unit coupled with my X305 blows it away in that regard. Hard to not find a way to replicate a certain sound given all the options.

CAUTION THOUGH, remember to flip the switch under your HU when you install this thing. I forgot to, tuned it on, and it sounded TERRIBLE at first. Low frequencies sounded damaging to the woofers (loud buzzing and crackling) and high frequencies appeared distant and muddy.

A must buy for audiophiles

September 26, 2008

This unit is just simply amazing.. I installed it on my X100 deck yesterday and WOW. The difference in the quality of the sound is like night and day. Much more clear.. The pre-out are a much higher voltage. There are hundreds of setting, including timing correction for perfectly tune you system... This is by far the most important purchase on my system
