ASP-Q2

Crossover

$499.99MSRP · USD

The ASP-Q2 is a full-system preamp and 7-band parametric equalizer designed as a precision tuning tool for serious car audio systems. It delivers up to ±12 dB of correction at any point in the frequency spectrum through audiophile-grade internal components and precision pots, producing a maximum output of 7 V RMS. Separate bass-level control balances low frequencies against the highs, and each channel of both Main and Aux inputs has its own independent level adjustment.

Key Features

  • 7-band parametric EQ with ±12 dB boost/cut per band across seven frequency ranges
  • Subwoofer output with continuously variable crossover from 30 – 300 Hz
  • Subsonic filter adjustable from 15 – 50 Hz protects woofers from harmful low-frequency energy
  • 2-channel inputs (Main + Aux) with per-channel level trims; 3-channel outputs (Front, Rear, Sub)
  • 7 V RMS maximum output voltage — well above typical head-unit preamp levels
  • 90 dB S/N ratio and 0.03% THD through audiophile-grade signal path components
