Rated 4.9 (120 reviews)
The Ecler AURA-4B600 is a four-channel Class D installation amplifier rated at 4x 600W into 4 ohms. Each pair of channels can be set to low impedance (2, 4 or 8 ohms), 70V or 100V line, or bridge mode, so a single 1U unit can run several zones of mixed speaker types. Typical uses are multi-zone background music and paging in bars, restaurants, hotels, retail, gyms and schools.
