RCF has released the XPS 16K and XPS 16KD (with Dante) class-D amplifiers with multichannel audio DSP engine, able to deliver four channels of 4kW of continuous power at 2.7Ω from compact 2U-high chassis.
The XPS series amplifiers see high-pass filters and their artifacts 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.
FiRPhase, a proprietary and advanced digital FiR technology provides a coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies in the system. The design combines traditional and proprietary processing, delivered by two 40-bit floating-point SHARC chips running at 96kHz.
Each output channel features 4000ms of output delay (1372m/4501ft) plus a wide palette of EQ and dynamics processing. Advanced algorithms expand the flexibility of the amplifier further, which can be used in linear mode with advanced tuning capabilities. A pair of 96kHz, 32-bit DSP chips manage internal routing of four XLR inputs (four analogue or two analogue plus four AES/EBU digital channels) and the optional Dante I/O.
Designed with a fault-tolerant architecture, 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 loudspeaker impedance measurement and forced air convection heat dissipation using speed-controlled fans.
Local control of XPS 16K models is handled via a 4.3-inch TFT colour capacitive touch-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 clear and unambiguous, even in very bright or sunny conditions.
Further, the XPS 16K amplifiers feature RCF’s RDNet-OE (Over Ethernet), which represents the latest advancement in RDNet networked management for RCF-compatible products. RDNet will detect any new devices on a network, take immediate control, and provide monitoring from a remote computer. Each XPS unit features four Ethernet ports on the rear panel, simplifying integration into any existing Ethernet infrastructure – including Dante on the D model. Multiple XPS 16K units can be interconnected, connected to other RDNet-compatible devices, or linked to computers running RDNet software, all without needing an external RCF Control device. All four LAN ports connect to the internal 1Gb/s switch, ensuring seamless network convergence.
The XPS 16K supports and enables the RCF philosophy of a power-agnostic approach where integrators and system designers have complete flexibility in choosing powered loudspeaker modules (with the XPS 16K providing processing) or an externally amplified approach, where the XPS 16K delivers both processing and amplification, balancing portability, weight, ease and speed of installation and cabling considerations.
