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.
Equalizer Frequencies
The frequency range that allows control of the center frequency of each equalization band.
25 - 18000 Hz
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.
9V volts
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 Hz = 30 kHz
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.
98.7 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.

MA audio makes great stuff

March 14, 2005

This is the most amazing deal perhaps ive ever seen on this site. 30 band equilizers like this noramlly go for upwards of $800. In my experience of installing car audio, i have never heard anything bad about MA Audio, and heard they make great stuff. If this equilizer is anything like the rest of there line-up of top quality audio components, i would jump on the chance to get this eq. if your looking for a high-quality eq to top off your system and fine toon it that last bit, this will fit your needs perfectly!
