Dedicated DSP sound processors from HELIX and BRAX, built for precise in-car audio tuning independent of your amplifier. A standalone DSP processor gives you time alignment, parametric EQ and crossover control ahead of your amps, ideal for multi-amp systems or when you want processing power separate from your power stage. Every processor here is genuine Audiotec Fischer gear, Australian-stocked and warranty-backed.
