The Dayton Audio DSP-408 is a versatile 4x8 digital signal processor designed to bring studio-grade sound shaping to both home and car audio systems. Whether you are fine-tuning a multi-channel home theatre setup or optimising speaker performance in a vehicle, this compact module delivers exceptional control over your audio environment.

Built around the powerful Analog Devices ADAU1701 engine, the DSP-408 processes audio at 24-bit/48 kHz resolution for clean, accurate signal handling. Its four low-level RCA inputs and four high-level inputs via a 16-pin wiring harness allow seamless integration with factory or aftermarket head units. The eight RCA outputs provide ample channels for complex crossover networks, time alignment, and equalisation. Maximum input levels reach 3.2 V on RCA and 8 V on high-level inputs, while a low output impedance of 50 ohms ensures reliable signal transfer. The unit operates on 9–17 VDC, making it suitable for automotive electrical systems, and measures a compact 166 x 116 x 26 mm for easy mounting. Calibration is handled through dedicated Windows software or Android/iOS apps, giving you intuitive control over every parameter.

With its robust feature set and flexible connectivity, the DSP-408 is the ideal solution for audiophiles seeking precise, customisable sound optimisation in any listening environment.
