AURA-4L150 is a multichannel, 4x150 W RMS @ 4 Ω, high efficiency amplifier (class D). AURA Series are built with the highest robustness for long lasting performances with special power supply circuitry designed for optimized electrical consumption and are 100% silent featuring convection cooling system. AURA Series also features the possibility of linking channels to the first input by selecting it on the rear panel, adjustable auto stand-by level, overload and thermal protection, PFC and anti-clipping system.

4 analogue audio inputs and 4 x150 WRMS @ 4 Ω powered audio outputs.
Euroblock input and output connectors.
Link to input 1 available.
Volume control knobs on front panel, that can be blocked via switches accessible from the bottom cover.
High efficiency, auto stand-by function and convection cooling (fanless, 100% silent).
Thermal protection.
Overload protection.
Anti-clip system.
