RCF Forstærker QPS 10 k 10000 W 4 x 2500 W 2 Ohm

QPS 10K 4 kanals professionel forstærker

QPS-serien er en serie af fire-kanals professionelle forstærkere, der kombinerer højkvalitets ydeevne og pålidelighed med de nyeste effektforstærkningsteknologier. Dette højværdidesign tilbyder, i kompakt 2-rack enhedsplads, lydkvaliteten og holdbarheden af klasse HD-forstærkere med innovationen af de nyeste strømenheder til rådighed. QPS 10K er en 4-kanals effektforstærker, der leverer op til 4 x 2.500 W @ 2 Ohm. Den har uafhængig forstærkningskontrol, signal-/klip- og fejlindikatorer, kanal A og C XLR-udgangslink, parallel-/brotilstande og speakON-udgangsstik. Desuden er den beskyttet mod kortslutninger og åbne kredsløb. Takket være dets højeffektive køleplader og ventilatorer med variabel hastighed kan QPS 10K modstå de mest ekstreme varmeforhold, hvilket sikrer pålidelighed.

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.
