AUDAC EPA502 Dual-Channel Amplifier 2x500W Class-D 1U Rack

The AUDAC EPA502 is a professional dual-channel power amplifier designed for fixed installations and mobile PA systems. Featuring a fanless Class-D design, it delivers 2 x 500W RMS at 4 Ohms or 2 x 250W RMS at 8 Ohms, with bridged capability up to 1000W at 8 Ohms. Its compact 1U 19" rack-mountable chassis ensures efficient use of space, while convection cooling guarantees silent operation—ideal for noise-sensitive environments like conference rooms, houses of worship, and retail spaces.

Advantages

This amplifier combines high power output with exceptional energy efficiency and silent cooling. The fanless design eliminates mechanical noise, making it perfect for studios, boardrooms, and auditoriums. Comprehensive protection circuits (DC, short circuit, overheating, overload) safeguard both the amplifier and connected speakers. Balanced XLR inputs and Speakon-compatible outputs provide reliable connectivity for professional audio systems.
