Four independent channels. Maximum installation flexibility.

The Ecler® AURA-4B150 is a professional four-channel installation amplifier designed for demanding audio projects requiring multiple independent loudspeaker zones within a single compact unit. Delivering 4 × 150 W of Class-D amplification, it supports both low-impedance loudspeakers (4 and 8 Ω) and 70/100 V constant-voltage systems.

Its versatile architecture makes it particularly suitable for multisensory environments, educational facilities, therapeutic spaces and professional multi-zone audio installations. The four independent amplifier channels allow installers to power different areas or combine loudspeakers and vibroacoustic elements while reducing rack space and simplifying system design.
