About the Hertz H8 DSP
From our tech experts at CEN
An 8-channel digital sound processor with equalisation and time alignment, the piece that corrects for the fact that a car is an acoustically awful place to listen to music.
Who it suits
Anyone who has bought good speakers and amplification and still feels the sound arrives from the wrong place. A DSP is also what makes a factory-fit system usable as a signal source when the head unit cannot be replaced.
Our tech experts advise
A processor is only worth what the tuning puts into it: the hardware does nothing until someone measures the car and sets delays, crossovers and EQ for where you sit. We tune DSPs in the vehicle at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.
