Restore Deep Bass Lost in Recordings

The AD7500B digital bass restoration processor is designed to bring your music back to life by recreating low-frequency content often lost during recording or compression. Its dedicated digital bass driver circuit enhances depth and warmth across all music formats, delivering fuller, richer sound that transforms your entire car audio system into a more immersive listening environment.

Precision Controls for Tailored Low-End Performance

Fine-tune your bass exactly how you want it using the dual rotary tuning system. The SWEEP control allows you to select the bass center frequency from 27Hz to 63Hz, while the WIDE knob adjusts the range of enhancement. Together, these controls let you shape your system’s low-end response for tight punch, deep rumble, or balanced warmth depending on your music style.

Clean Signal Integration with Professional Audio Specs

Built for high-performance systems, the AD7500B offers an impressive 10Hz–35kHz frequency response, 133dB signal-to-noise ratio, and extremely low 0.0025% distortion. Balanced RCA inputs accept up to 15V RMS and provide strong noise rejection to reduce engine whine and electrical interference. The included dash-mounted remote with LED indicator gives you instant control over bass output, while the selectable PFM subsonic filter removes inaudible frequencies that waste amplifier power.
