The Audac EPA252 is a powerful, energy-efficient dual-channel Class-D amplifier delivering up to 2 x 250W at 4Ω. Designed in a compact 1U rackmount format, this lightweight unit is ideal for fixed installations and mobile audio systems where performance, reliability and efficiency are essential.
Featuring convection cooling, advanced protection circuitry and automatic standby functionality, the EPA252 provides high output power with minimal maintenance and exceptionally low standby energy consumption.
Utilising advanced Class-D technology, the EPA252 delivers clean, stable amplification with excellent efficiency and minimal heat generation. Output ratings include:
A wide frequency response of 20Hz – 20kHz (±3dB) and THD+N below 0.1% ensure accurate and distortion-free audio reproduction across the full spectrum.
The EPA252 is Energy Star certified and automatically switches to standby mode after approximately 30 minutes without signal detection, consuming just 0.8W in standby. This makes it particularly suitable for commercial and permanent installations where energy efficiency is a priority.
Advanced internal circuitry provides comprehensive protection against:
The fully convection-cooled (fanless) design ensures completely silent operation and long-term reliability without the need for active cooling or regular maintenance.
Balanced XLR input connectors with male link-through outputs allow simple daisy-chaining of multiple amplifiers. Speaker outputs are provided via SpeakON-compatible connectors and 2-pin Euro terminal block connectors for flexible installation options.
