RCF has introduced the KPS Series Class-D multichannel amplifiers, engineered to deliver high levels of flexibility, efficiency and system control across a wide spectrum of professional installation environments including conference centres, corporate systems, retail spaces, theme parks and museums. Designed to address the growing complexity of modern AV deployments, the series offers scalable configurations ranging from 2 to 8 channels, with power outputs spanning 160 W to 800 W per channel, and compatibility with both low-impedance (2.7, 4 and 8 ohms) and high-impedance (70 / 100 V) systems.

At the core of the range, the KPS 16X Series stands out for its high power density, delivering four independent 160 W RMS channels within a compact 1 U, half-rack-width chassis. Its intelligent power-sharing architecture enables dynamic reallocation of up to 300 W to any individual channel, allowing integrators to distribute power asymmetrically without the need for bridge mode or reduction in channel count, thereby optimising headroom when driving RCF loudspeakers.

The amplifiers are equipped with a universal, regulated switch-mode power supply (SMPS) with Power Factor Correction (PFC) and an integral standby converter, automatically adapting to mains voltages from 100 V to 240 V at 50 – 60 Hz to ensure consistent global operation. A comprehensive suite of protection mechanisms safeguards the system against short circuits, DC offsets, high-frequency faults, undervoltage, excessive temperature and overload conditions, supporting long-term operational reliability.

RCF’s Class-D output stage employs a full-bandwidth pulse-width modulation (PWM) modulator capable of reproducing the entire 20 Hz–20 kHz frequency range with minimal phase shift. Combined with high-speed switching and real-time global feedback, the design maintains total harmonic distortion below 0.05 %, delivering clean, wide-band audio performance while minimising heat generation within a compact and lightweight form factor.

In terms of connectivity, the KPS Series supports both balanced and unbalanced analogue inputs alongside an S/PDIF digital input that can be forwarded across multiple units to create a shared audio bus. The amplifiers can also be specified with an integrated Audinate Dante audio-over-IP interface, enabling bidirectional, low-latency, lossless multichannel audio transmission over standard Ethernet networks. This ensures seamless interoperability with established control and automation platforms including Q-SYS, AMX, Crestron and Control4.

Complementing the amplifier range is the RC KPS, a wall-mounted, networked PoE controller designed to provide intuitive input selection and volume control. Built with a minimalist aesthetic using high-performance polymer and a touch-friendly matte finish with concealed screws, the controller supports up to eight units per KPS amplifier and allows flexible zone assignment via RDSpace. Features include instant network pairing, quick source selection, level management, PIN code protection, and customisation options with four display colour schemes, four brightness settings and four button backlight configurations, with EU and US versions available in white (RAL9003) and black (RAL9005).

System management is handled through RDSpace, RCF’s adaptive software platform for configuring and monitoring KPS amplifiers within professional audio networks. Offering a unified interface, the platform enables comprehensive control over input routing, zone configuration, output optimisation and speaker calibration, while supporting real-time monitoring across installations of varying scale. RDSpace incorporates linear-phase FIR filtering, speaker presets and user presets, flexible routing, parametric EQ, precision delay and full device control, allowing operators to manage complex, multi-zone systems efficiently from a single application.

With its combination of scalable power configurations, advanced DSP capabilities, extensive connectivity and integrated control ecosystem, the KPS Series positions itself as a robust and versatile solution tailored to the evolving demands of contemporary professional AV installations.
