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.
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.
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.
Equalizer Frequencies
The frequency range that allows control of the center frequency of each equalization band.
Signal Boost/Cut
The available signal boost or cut for each of the frequency bands.
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
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).
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.
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.

Excellent product. Just make sure the manufacture date is recent.

May 13, 2010

This unit works great with the JL Audio CleanSweep CL-441dsp unit. Just be aware that your input connections may not match those specified in the instruction manual. For example, I needed to 2-way sum mid-range and tweeter signals, and I had to use inputs A (tweeter) and C (mid-range) for the CL-441dsp calibration to work properly. The instructions incorrectly specified using inputs A and B, since C is a dedicated low-pass signal input. Regardless, it is working great now, and I highly recommend it. Also be aware that older CleanSweep CL-SSI units have flawed hardware and will not work properly (according to JL Audio tech support--call and they can diagnose this based on serial number). Before buying from SonicElectronix, I purchased another unit on eBay that was manufactured in 2006 that did not work and had to be returned.

Sonic Electronix had the best price and it was in stock! I've bought a number of things from you guys before and I've always been really happy with everything I've purchased. You guys are the first place I check when I'm looking for new equipment to upgrade my car audio system and I love how you always have what I am looking for and what I need. It's to bad you don't have local storefronts to where I could run down to the store and get what I need. Maybe one day my dreams will come true!
