| General Specifications | |
Frequency Response Frequency Response in a car amplifier refers to the range of audio frequencies it can amplify, typically measured in Hz. For example, a response of 20Hz to 20kHz indicates the amp can handle deep bass to high treble, covering the full audible spectrum.
|
|
S/N Ratio S/N Ratio (Signal-to-Noise Ratio): A measure of an amplifier's ability to amplify audio signals relative to background noise. A higher S/N ratio indicates clearer sound, as more of the output is dedicated to the signal rather than noise.
|
|
THD+N @ Rated Power THD+N (Total Harmonic Distortion plus Noise): A measurement of the total distortion and noise introduced by an amplifier. Lower values indicate cleaner audio reproduction, as less distortion and noise affect the output signal.
|
|
Input Voltage Range Input Voltage Range: The range of voltage levels an amplifier can accept from the audio source. It determines compatibility with various head units or signal processors, ensuring optimal signal strength without distortion or clipping.
|
|
Low Pass Filter Low Pass Filter: A feature that allows only frequencies below a specified cutoff point to pass through to the subwoofer, blocking higher frequencies to ensure cleaner bass output.
|
|
Crossover Slope Crossover Slope: The rate at which frequencies are attenuated beyond the crossover point, measured in dB per octave. Steeper slopes (e.g., 24 dB/octave) provide more precise separation between frequency ranges, improving sound clarity.
|
|
Fuse Rating Fuse Rating: The maximum current an amplifier can handle before its fuse blows, protecting the unit from damage. It indicates the amp’s power capacity and helps ensure safe operation within the electrical system.
