RCF UP 2321 - 320W at 4-Ohm 70V/100V Power Amplifier in Black Finish

The RCF UP 2321 is a high-performance power amplifier designed for both announcement and music transmission, offering exceptional audio quality and flexibility in a range of installations. This 320W amplifier is perfect for PA systems, broadcasting environments, and background music applications, providing powerful amplification for both low impedance and 70V/100V constant voltage lines. The UP 2321's Class D technology, combined with a switching power supply, ensures a lightweight yet robust design with outstanding efficiency and sound reproduction across a wide frequency range.

The UP 2321 features multiple input options to accommodate various audio sources. It includes a main mic/line input, which can be connected through removable connectors, XLR, or RJ45, allowing for easy integration into any system. The main input can be configured with a priority function, which ensures that announcements or critical signals are automatically given precedence over background music. This priority feature is ideal for situations where speech needs to be clearly heard over other audio sources. Additionally, the main input includes a presence control for optimizing vocal clarity and a high-pass filter to enhance speech intelligibility, making it particularly well-suited for PA and communication systems.

The amplifier also has an auxiliary input for music sources like CD players or tuners, connected via RCA connectors. The auxiliary input features tone controls for adjusting the volume, bass, and treble, allowing users to fine-tune the sound for their specific environment. This level of control ensures optimal performance for both voice and music content, making the UP 2321 versatile and adaptable in a wide range of settings.

The amplifier offers both low impedance (4 ohms) and 70V/100V constant voltage outputs, making it compatible with a variety of speaker systems. Whether used with high-power line-array setups or low impedance loudspeakers, the UP 2321 delivers consistent and reliable performance. The front panel features LED indicators for power, protection, and signal levels, providing immediate feedback on the amplifier's status. The compact design makes it easy to install in a standard 19" rack, occupying just 2U of rack space, while its convection cooling system ensures quiet operation without the need for noisy fans.

In terms of protections, the UP 2321 is equipped with short circuit, thermal, DC, and fuse protection mechanisms to ensure safe operation in all conditions. With its high-quality build, advanced features, and flexible functionality, the UP 2321 is an ideal choice for a wide variety of professional audio applications, from commercial installations to live events.
