RCF’s new IPS Series of high-performance, adaptable 2U-high class-H topology power amplifiers are intended for install applications, and offer configuration as two single-channel outputs of two parallel outputs or a single-channel bridge, in three power options – 2x 2.6kW (IPS 5.0K), 2x 1.25kW (IPS 2.5K), and 2x 750W (IPS 1.5K) at 4Ω.

Class-H amplifiers modulate the supply voltage to the amplifier output devices so that it is never higher than necessary to support the signal swing. This reduces dissipation across the output devices connected to that supply and allows the amplifier to operate with an optimised efficiency, regardless of output power level. Up to full power, a class-H design will require less energy than a pure class-AB design, and is better suited to high-power applications.

IPS amplifiers incorporate several protections 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 the optimal 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.
