QPS Series is a range of four channel professional amplifiers that combines high-quality performance and reliability with the latest power amplification technologies. This high-value design offers, in compact 2-rack unit space, the sound quality and the durability of class HD amplifiers with the innovation of the latest power devices available. QPS 10K is a 4-channel power amplifier that delivers up to 4 x 2,500 W @ 2 Ohms. It features independent gain control, signal/clip and faults indicators, channels A and C XLR output link, parallel/bridge modes, and speakON output connectors. Moreover, it is protected against shorts and open circuits. Thanks to its high-efficiency heat sinks and variable speed fans, QPS 10K can withstand the most extreme heat conditions ensuring reliability.

HD Designed Driving Power

Our HD amplifier technology features 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. The power supply rails continuously track the input signal for remarkable 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 2 Ohms nominal.

Remarkable Audio Performance

With a very high signal-to-noise ratio, QPS amplifiers also boast a very low total harmonic distortion, making it perfect for highly demanding music applications hence delivering perfect vocal intelligibility.

Self-protecting Architecture

QPS amplifiers implement several safety strategies protecting 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.
