Automotive DSP with 15-band EQ

The WUQ Pro 2.4S is a digital signal processor designed for car audio systems. It provides 15-band graphic equalization and crossover management for two input channels and four output channels. Installers and enthusiasts use it to tune frequency response and signal routing in multi-amplifier setups.

Replaces passive crossovers and basic EQs

This unit replaces fixed passive crossover networks and limited analogue equalizers with fully adjustable digital filters. The upgrade is worth it when you need independent control over each output channel, precise filter slopes from 6 to 48 dB per octave, or the ability to store and recall 12 preset curves for different listening preferences.

Limited to two-channel input topology

The processor accepts only two input channels, so systems requiring more than two discrete source signals cannot be accommodated without external summing. Output routing is fixed at four channels, restricting configurations that need five or more independently processed outputs. The highest crossover frequency available is 22 kHz, and maximum output attenuation reaches 45 dB.

Questions about this item

Does the Pro 2.4S need a specific DIN opening or rack space to mount?

The unit is a compact DSP processor designed for automotive installation; it does not require a standard DIN opening and can be secured in any suitable location with the supplied brackets.

What wiring step do installers most often miss when connecting the 2-in 4-out DSP?

Remember to run both input channels A and B into the processor and assign each of the four outputs to the correct crossover filter before powering up.

Will the 15-band graphic EQ or the 12 factory presets need periodic recalibration?

The equalizer settings and presets are stored digitally and remain stable; no recalibration is required unless you deliberately change the curves or load new presets.
