RCF has launched the QPS Series of high-performance, versatile power amplifiers for touring and install applications. Using class-HD topology, the amplifiers feature a very efficient power output section with a design ‘focused on musicality, maintaining a natural and clear sound at all frequencies, with smooth highs and a tight, high impact low end’.

Wth four single-channel outputs or one/two bridged outputs, parallel or stereo, three dip-switches allow setting the maximum output voltage peak for each channel among eight values. High-efficiency heat sinks and variable-speed fans can withstand extreme heat conditions, ensuring steady power output stability over time. High-quality, low-distortion audio output, and industry-standard speakOn connectors make QPS Series the hassle-free solution for both sound systems and permanent installation.

The power supply rails continuously track the input signal for signal purity, while preserving the high efficiency of the class-D design. QPS amplifiers are bridgeable and maintain high reliability with complex loads as low as 2Ω nominal.

QPS amplifiers feature protection for both the amplifier and the sound system, including an effective peak limiting protection for the transducers. The temperature-controlled continuous variable speed double-fan system (front to back), combined with the high-efficiency heat sinks, allows the amplifier to maintain a safe, working temperature no matter the environmental temperature or the power output. The circuit is protected from overheating and short circuits, also including protections against infrasonic DC and Very High Frequency (VHF) peaks from non-musical signals that could damage transducers.
