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.
9 band
Equalizer Frequencies
The frequency range that allows control of the center frequency of each equalization band.
40 - 120 Hz
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)
Full (AP)
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.
No
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
No
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.
Green or Red
Signal Boost/Cut
The available signal boost or cut for each of the frequency bands.
12 dB
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
5 volts

Give it a 6...

August 27, 2010

Initially I was impressed with the added advantages of an EQ, but over the last 6 months I've started to notice some very frustrating problems with this particular unit.

Con # 1) It crosses the front/rear channels at 100Hz whether you like it or not. If you already have passive component crossovers, or are using the preamp on your amplifier, you are out of luck with this EQ. There is a button to defeat this crossover, but if you push it, it also turns off your subwoofer gain knob! This part really ticked me off.

Con # 2) The EQ allows you to boost any bass frequency between 40 - 60Hz. This is nice as a bass boost, but it also boosts that bass frequency on the front/rear channels! So if you want to boost your subwoofer at 40Hz, you end up distorting the hell out of your other speakers which certainly cannot handle that kind of boost. What's even worse, this boost knob not only boosts the selected bass frequency, but it also boosts ALL 7 OF THE OTHER BANDS! That wasn't mentioned in the manual.

Con # 3) The remote-on circuit blew about 1 week into owning it.

The features on this EQ completely defeat the purpose of an EQ, which is to flatten your system by only boosting and cutting what you WANT to be boost and cut.

It's OK- Minus the alternator whine

August 2, 2010

One thing you have to remember about EQ's- for whatever reason they are usually noisy. Meaning, they inject noise, whine, and hiss into your system. But after tweaking my amps down, the whine is to a minimum, the hiss is hardly audible, and the noise is tolerable. One thing I have to say I don't like is the high voltage inputs. It was so noisy, I used filters, grounds, ground lifters, I tried everything, and nothing worked. Finally I bought a high level to low level converter and that worked well. Once I got everything tweaked out I have to say I like it-but it was a hassle getting it there.
