RCF UP 2321 Power Amplifier (320W)

The UP 2321 is a compact, high-efficiency 320W RMS digital power amplifier designed for professional audio distribution in commercial and public address systems. Built on Class D technology with a switching power supply, it offers exceptional audio clarity with reduced weight and wide bandwidth performance. It includes a Main Input that accepts connections via removable terminal, XLR, or RJ45, and supports both mic and line level signals with phantom power and a high-pass filter for optimized speech transmission. The Main Input can be given priority over the Auxiliary Input, which is designed for music playback through an RCA connector and includes tone and volume control. The amplifier is equipped with both low-impedance (4 ohm) and high-voltage (70V/100V) outputs, ensuring flexible installation options. Additional control features include DIP switch configuration, VOX activation, and GPI compatibility. The UP 2321’s convection cooling, integrated safety protections, and 2U rack-mountable chassis make it a reliable, space-efficient choice for professional installations.
