RCF's UP8501 is a 500W power amplifier featuring 2 inputs per channel, dual AC and DC power supply, priority circuitry, no output lines tranformers, and status LEDs on front panel.

The UP 8500 series power amplifiers are designed with an innovative RCF power supply and amplification technology. The full digital technology allows merging extremely high efficiency both with AC and DC power supply, pro audio quality reproduction and compactness. All UP 8500 series power amplifiers are certified according to EN 54-16 standard in combination with DXT 7000 Voice Alarm system.

The full digital technology used in these new products allows extremely high efficiency both with AC and DC power supply operation, Pro-Quality audio reproduction and compactness: all the three models are built-in a single 19” Unit.
The switching mode power supplies include an independent DC 48 V section that guarantees extra redundancy to the possible failure of the units. Each channel is provided with two inputs and dedicated priority circuit to get mix/mute and exclusive priority operation. The amplifiers are suitable for 70/100 V applications, using a unique RCF technology that allows to eliminate the line output transformer. Several status LEDs on front panel give a complete feedback on amplifier status, a DIP switch on rear panel allows to disable the frontal volume controls in order to avoid misuses. All connectors are removable screw terminals.
