According to RCF, these professional stereo power amplifiers are designed using ultra-high efficiency class-H mode topology, providing from 2 x 800W up to 1 x 3200W, at an efficiency of around 85%. A powerful transformer-based power supply and hand-selected components make these power ratings possible with exceptional audio quality and absolute reliability, even in 2 ohm mode, say the company. The PA output stages are fully protected against over-temperature, short circuit and RFI and are equipped with soft start circuit and temperature-controlled fan cooling.
The integral soft clip limiter protects against damage to the connected loudspeakers. The activity of a protective circuit, signal and limiter is shown for each channel by LEDs. Input connections are via two XLR and 2 parallel quarter-inch jacks. Speaker outputs are provided on two Speakon 4-out terminations.
