About the Hertz H8 DSP

From our tech experts at CEN

The Hertz H8 DSP is an 8-channel car audio digital signal processor with a 31-band graphic EQ and time alignment on every output. It accepts speaker-level inputs from a factory head unit, plus AUX and optical S/PDIF (up to 96 kHz/24-bit). Each output has its own crossover and delay (0–15 ms, up to 510 cm), and the DRC HE remote control is included.

Who it suits

The H8 DSP suits enthusiasts building a multi-way active car audio system who need precise per-channel control of level, timing and tone. It works equally well to upgrade a factory head unit setup. Pair it with speakers from the Hertz range for a complete system.

Our tech experts advise

Setup uses Windows PC software over USB; there is no app. The speaker-level inputs accept 2–15 V RMS, covering most factory head units. Fitting is priced per vehicle — see our car audio installation service for a quote.
