RCF UP 8502 - 2 x 250W at 100V Power Amplifier with EN54-15 Certification in Black Finish

The RCF UP 8502 is a high-performance 2 x 250W power amplifier designed for use in critical audio systems, especially those requiring compliance with emergency sound standards. This amplifier is part of the UP 8500 series, which integrates advanced RCF power supply and amplification technology, offering exceptionally high efficiency with both AC and DC power supply. The UP 8502's digital technology allows for precise, professional audio reproduction, combined with a compact design ideal for both fixed and mobile installations. Certified to the EN 54-16 standard, it is fully compatible with the DXT 7000 Voice Alarm system, ensuring that it can be used in emergency voice alarm systems with a high degree of reliability and performance.

With a robust 2 x 250W output at 100V, the UP 8502 is suited for both low impedance loudspeakers (minimum 4 ohms) and constant voltage 70V/100V systems. This makes it versatile for a range of applications, from public address to emergency systems. The amplifier features a dual AC and DC power supply, which ensures uninterrupted operation in case of a power failure, thanks to its battery support (48V DC). The amplifier also offers a priority circuit, which ensures that emergency audio signals are always given precedence over background music or other non-emergency audio sources. This is a crucial feature for emergency audio systems where announcements or alarms must be heard above all other audio.

The UP 8502 comes equipped with 4 balanced inputs (Euroblock connectors), allowing for flexible connectivity in complex audio systems. It also offers General Purpose Inputs (GPI) and a General Purpose Output (GPO), enabling further integration with other system components, such as fire alarm systems or remote control units. The amplifier's output section is equipped with Euroblock connectors, simplifying installation in various setups. The amplifier features forced cooling to maintain optimal temperature levels, ensuring safe and reliable operation under heavy load conditions. Built-in protection features such as short circuit, thermal, DC, and fuse protection safeguard both the amplifier and connected equipment, enhancing its durability and performance.

The front panel of the UP 8502 includes status LEDs to provide visual feedback on the device's operational status, including power, protection mode, and signal levels. This makes monitoring easy for audio technicians, particularly in live event or critical installation scenarios. Additionally, the amplifier is designed with no output line transformers, reducing complexity and the risk of signal degradation. With a wide frequency response range of 40 Hz to 16 kHz, the UP 8502 delivers clear and high-quality audio for a wide range of applications, from speech intelligibility to high-fidelity music playback.

With its full digital technology, EN 54-16 certification, and feature-rich design, the RCF UP 8502 is the ideal solution for both high-performance installations and emergency audio systems. Its compact, rack-mountable 1U design makes it easy to integrate into standard rack systems, while its powerful features ensure it performs reliably in a variety of professional audio applications.
