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.
10 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)
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
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.
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
4 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 - 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.
98 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.

is there a reason that this piece if retail and not on the vip shipping program?
A shopper on Aug 31, 2016
Best Answer: Hello,

The VIP Guarantee program is not a shipping program. Although some products under the program get free 2 shipping that is hardly the main perk. In fact, this item is currently being processes as a VIP product, but will not receive Free 2-Day. This may change at any point, but won't at the moment. Give our sales team a call and they might be able to make an exception. (That is not a promise.)
