Digital Sound Processors FAQs

Q: Do I need a DSP?

A: A DSP is worthwhile if you want an active system or to correct a factory system's tuning. It adjusts EQ, crossovers and time alignment.

Q: Does a DSP replace my amplifier?

A: No. A standalone DSP processes the signal and feeds separate amplifiers .

Q: Can CEN tune my DSP?

A: Yes. CEN can supply, fit and tune processors at our Beeston, Nottingham workshop.
