  • Bass Reconstruction Processors Specifications

    Input Connection Type
    This is the type of input that the unit accepts.
    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.
    Output Connection Type
    This is the type of output that the unit accepts.
    Maximum Input Voltage
    This is the maximum voltage that the processor is able to accept.
    15 volts
    Maximum Output Voltage
    This is the maximum voltage that the processor is able to output.
    13.5 volts
    Adjustable Center Frequency
    This function allows you to adjust the center frequency of the signal proccessing.
    LED Indicators
    This refers to any LED illumination present on the unit. This includes Power Indicators, Clipping Indicators, illuminated logo's, etc.
    Bass/Gain Remote
    If the unit comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
    Auxiliary Input
    This refers to whether or not the unit has an auxiliary input for connecting additional accessories.
    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.
    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 normally used with subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, which is normally used with speakers.
    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).
    10 - 100,000 Hz
    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.
    130 dB
    Total Harmonic Distortion (THD)
    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.
