Rated 4.9 (120 reviews)
The Ecler DARA-4B600 is a four-channel Class D installation amplifier with built-in DSP and network control, rated at 4x 600W into 4 ohms. Each pair of channels can run at low impedance, on 70V or 100V lines, or bridged, and a 4 x 4 input matrix, speaker presets and limiters are set from a web browser. It is used for multi-zone systems in bars, restaurants, hotels, retail, gyms, offices and schools where the amplifier also handles the processing.
