RCF debuted its XPS 16K high-power four-channel amplifier with a DSP. Designed for both touring and installed sound systems, RCF says the XPS 16K and XPS 16KD (with Dante) feature a multi-channel audio DSP engine and a multi-channel Class-D amplifier delivering 4 x 4000 W of continuous power at 2.7 ohms, all in a compact 2U chassis with signal-to-noise, distortion and dynamic range specifications.

According to RCF, high-pass filters and its artifacts are replaced by Bass Motion Control, a “forward-thinking approach” to woofer excursion management. BASS Shaper, Air Compensation, and Mid-Low Correction algorithms extend LF management.

Each output features 4000 ms of output delay (1372 m / 4501 ft), plus a broad palette of EQ and dynamics processing. RCF says a host of algorithms expand the amp’s sonic flexibility, which can be used in linear mode with advanced tuning capabilities. A pair of 32-bit / 96 kHz DSP chips manages the internal routing of four XLR inputs (four analog or two analog plus four AES/EBU digital channels) and the optional Dante I/O.

Designed with a multi-faceted fault-tolerant architecture, RCF says the XPS 16K’s closed-loop digital protection includes RMS signal protection to protect transducers from thermal issues, power supply output dynamic limiting and overvoltage protection, peak overvoltage and RMS overcurrent short circuit protection plus gain modulation for thermal protection. Hardware protections include current- and voltage-based protection, monitored speaker impedance measurement and forced air convection heat dissipation utilizing speed-controlled fans.

RCF says local control of the XPS 16K is handled via a large 4.3-inch TFT color capacitive touch front-panel display that provides full operational control of the amplifier. The user interface is “intuitive and user-friendly,” featuring large-area touch buttons and a convenient edit knob. The high-contrast menus are designed to remain unambiguous, even in very bright or sunny conditions.
