Shure P4800 Digital Signal Processor (Used)

The Shure P4800 is a 1U rack-mounted digital audio processor that combines a flexible 4-input by 8-output matrix mixer with powerful DSP to optimize sound in installed and live reinforcement systems. Positioned between your mixer and amplifiers, it delivers precise routing, equalization, dynamics, and delay with dependable performance.

Configured with an intuitive drag-and-drop Windows application, the P4800 lets you build custom signal chains including parametric EQ, crossovers, compressors, limiters, feedback control, and delay in any order. Extensive preset management and external control options make it easy to standardize setups across venues or quickly recall scenes for different events.

With professional headroom, low noise, and 48 kHz, 24-bit conversion (32-bit floating-point internal processing), the P4800 maintains clarity from input to output. Security lockouts and remote integration suit auditoriums, houses of worship, boardrooms, and touring rigs.
