Audio Processor

Audio processors give you finer control over your system's sound than a head unit alone. This range includes the Hertz H8 DSP 8-channel digital processor with remote control, DS18 EQX7 and EQX7PRO 7-band equalisers, Boss Audio EQ1208 and Hifonics HFEQ-2 4-band equalisers, and the Boss Audio BX55 electronic crossover.

There's also the DS18 2CLC line output converter with a digital bass enhancer, handy for adding an amplifier to a factory stereo, and the Hertz Mille Legend MLCX 2 TW.3 crossover set. A DSP suits detailed tuning across many channels, while an equaliser or crossover is a simpler way to shape tone and send the right frequencies to each speaker.
