Rated 4.9 (120 reviews)
The Ecler AURA-2B1800 is the highest-power two-channel model in the AURA range, rated at 2x 1800W into 4 ohms and 2x 2400W into 2 ohms. Outputs can also run 70V or 100V lines at 1800W per channel, or be bridged for 4600W into 4 ohms, from a 1U chassis. It is aimed at large 100V systems and high-output low impedance installs in clubs, bars, sports halls, function rooms and places of worship.
