The Audac EPA152 is a compact, energy-efficient dual-channel Class-D power amplifier delivering up to 2 x 150W at 4Ω. Designed for fixed and mobile installations, this 1U rackmount amplifier combines lightweight construction, high efficiency and reliable protection circuitry for professional audio applications.
With silent convection cooling, automatic standby functionality and comprehensive protection systems, the EPA152 delivers dependable performance with ultra-low energy consumption.
Advanced Class-D technology ensures high output efficiency, reduced heat generation and clear audio reproduction across the full frequency range.
With a frequency response of 20Hz – 20kHz (±3dB) and THD+N below 0.1%, the EPA152 provides clean, accurate sound suitable for music and speech reinforcement.
Energy Star certified, the EPA152 automatically switches to standby mode when no audio signal is detected, consuming less than 1W in standby. This makes it ideal for commercial environments where power efficiency is essential.
Comprehensive protection circuitry safeguards against:
The fanless convection-cooled design ensures completely silent operation and reduced maintenance requirements.
Balanced XLR inputs with link-through outputs allow easy signal distribution to additional amplifiers. Speaker outputs are provided via SpeakON-compatible connectors and 2-pin Euro terminal block connectors for flexible installation options.
