AURA-1B300 is one channel, 1x300 W RMS @4Ω, high efficiency amplifier (class D). Compatibility with both Low and Hi impedance configurations. AURA Series are built with the highest robustness for long lasting performances with special power supply circuitry designed for optimized electrical consumption with fan cooling system. AURA Series also features the possibility of linking channels to the first input by selecting it on the rear panel, as well as auto stand-by, overload and thermal protection, PFC and anti-clipping system. The front panel volume knobs can be locked using rear panel switches for added security.

1 analogue audio input and 1x300 WRMS @4Ω powered audio output.
Low (2, 4 and 8Ω) and high impedance (70/100V) compatibility via rear panel switch.
Euroblock input and output connectors.
Euroblock connectors with anti-pulling locking system.
Link to input 1 available.
The front panel volume control knobs can be locked using the rear panel switches for added security.
High efficiency (Class D).
Auto Standby function.
