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.
Graphic
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.

Low-pass (LP)
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.
No
Total Number of Inputs
This is the total number of input connections that go into the unit.
2
Total Number of Outputs
This is the total number of output connections that the unit will produce.
3
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.

Blue
Signal Boost/Cut
The available signal boost or cut for each of the frequency bands.
18 dB
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
8 volts
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.
.05%
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.
110 dB

What a difference

March 31, 2014

I had recently purchased this eq for my mid bass and what a difference. I like my mids in the 125 hz range and this eq does just what it needs to do. Filters out the higher hz and gets more bass going to my mids

Wow, this thing is awesome!!!!

This equalizer really made my system come alive. Much better sound quality. The bass and treble really came alive. Sounds like I'm running much more than 1 Pioneer 12" sub. The only down fall is the frequencies do not light up. Other than that it is a great product for the value.

Great EQ. Works good for low and highs. A little hairy on mids, but good for starter EQ for the price.

I have a DUAL XHD7714 head unit. How should I connect this, through the stereo's sub out?
Dom B on Aug 7, 2014
Best Answer: connect it to the front channel outputs so that the equalizer gets a full range signal, the equalizer will separate the outputs for all of the other five channels
