General 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
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.

Low-Pass (LP)
High-Pass (HP)
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.
Display Color
The display color refers to the color of the text and or graphics on the receiver.

Multi-Color: When more than one color is on the display, for example one part of the text is white, while the other part is blue.

Variable-Color: The display colors can be changed by the user. If the default color of text/display is blue for example, the user can change the settings to where the color turns to red. Variable color displays are typically described in detail in the item's description.

TFT-LCD Display: In-dash receivers with a video screen that display multiple colors and often times video such as DVD, navigation or other video sources.

Button Color
Refers to the color of the physical buttons on the unit.
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.
82 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.

Awesome device for the $$!

October 29, 2009

As soon as I got this installed on my Lexus IS300 I couldn't wait to tune it. Calibration is NOT clear in the instructions nor did anyone post anything out there on the web. Alpine support wasn't that helpful, but they pointed me in the right direction.

Once calibrated, the stock speakers off of an aftermarket headunit and amps sounded amazing!

Amazing sound can be acheived with this device (after multiple calibrations [more than 20x]).
Best bang for the buck for a Sound Processor!

Calibration - Knowing where to set the mic to calibrate sucks! If you don't know the mic placement, 95% of the time your system WILL sound worst than the stock system.
Instructions are horrible.
Volume output - You NEED to run amps!! 3 amps would be best and let your HU adjust the subs.

Quick low down on calibration:
Turn your HU 3/4 all the way to the MAX.
Enter the calibration disk.
Follow the QUICK setup instructions (it gets the basics across fairly clearly)

Mic Positions:
Position 1 - Direct center of the Drivers head position.
Position 2 - Direct center of the Passenger's head position.
Position 3 - 2" Left of direct center of the Driver's head position.
Position 4 - 2" Right of direct center of the Driver's head position.
Position 5 - 4" Left of direct center of the Driver's head position.
Position 6 - 4" Right of direct center of the Driver's head position.
