The DPU-4.8 Digital Signal Processor is a powerful and versatile audio management solution
designed for professional sound reinforcement and installation applications. Equipped with 4 analog
inputs and 8 analog outputs, it operates at a high 96kHz/24-bit resolution for exceptional audio
clarity. The processor offers extensive tuning flexibility with 15-band PEQ on inputs and 10-band PEQ
on outputs, along with advanced filter options including Butterworth, Bessel, Linkwitz-Riley, and All Pass. With dynamic 3-band EQ, integrated FIR filtering (up to 512 taps per channel) and linear phase
processing, the DPU-4.8 ensures precise system alignment and superior sound performance. It also
features preset management with secure locking, and supports control via USB, TCP/IP, and RS232,
complemented by an intuitive Windows and Android-based control software for seamless operation.
