The Ecler AURA-8L150 is a professional-grade, high-efficiency multichannel amplifier designed for demanding commercial and installation audio environments. Delivering 8 channels of 150W RMS @ 4Ω using advanced Class D technology, it combines exceptional sound performance, energy efficiency, and compact fanless design—ideal for large-scale distributed audio systems.
Built for flexibility and reliability, the AURA-8L150 features both balanced analogue inputs and Euroblock output connectors, with input link selectors to streamline integration in complex setups. The amplifier’s universal power supply with power factor correction (PFC) ensures stable operation across a wide range of voltages (100–240V), while keeping energy consumption optimized—especially when paired with its Auto Standby mode, which reduces power use during inactivity.
Engineered with precision, the AURA-8L150 boasts a frequency response of 15 Hz – 30 kHz, ultra-low THD (<0.01%), and a high signal-to-noise ratio (100 dBA), ensuring clean and accurate sound across all channels. Multiple layers of protection—including short-circuit, thermal, HF, clip limiting, and DC protection—safeguard your system under all conditions.
Its fanless convection cooling system allows for silent operation, making it perfect for installations where noise must be minimized, such as conference rooms, museums, retail spaces, and hospitality venues.
With an ultra-slim 1U rack-mountable chassis and intuitive front-panel controls for attenuation, status LEDs, and standby switching, the Ecler AURA-8L150 is built for ease of use and long-term performance.
