Description
The RCF XPS 4K is a four-channel Class D DSP amplifier designed for demanding professional installed sound applications. Delivering up to 4000W of total continuous power, with 4 × 1000W at 4 ohms, it combines high power density with advanced digital processing in a compact 2U chassis.
Advanced DSP Processing & System Optimization
Each output channel includes comprehensive processing tools such as up to 4000 ms of delay, EQ filters, crossovers, FIR filters, multiband compression, RMS limiting, power limiting, and thermal protection. Advanced RCF technologies including FiRPHASE, Bass Shaper, air compensation, driver excursion control, and dynamic PEQ provide precise system optimization.
RDNet Control & Professional System Integration
The XPS 4K also provides extensive system management through RDNet, Gigabit Ethernet, onboard RCF speaker presets, and a front-panel color touchscreen. With analog and AES/EBU digital inputs, flexible routing, comprehensive protection circuitry, and rackmount construction, it is well suited to high-performance installed sound systems.
