Ecler HALO-4B300 Installation Amplifier with DSP, Dante & AES67, 4x 300W @ 4 Ohms or 70V / 100V Line

The Ecler HALO4B300 Installation Amplifier with DSP, Dante & AES67 is a 4-channel Class D amplifier with networked DSP, delivering 4x 300 W in low-impedance mode at 4 Ω or 8 Ω. Its four output channels can be bridged to drive high-impedance 70 V or 100 V loudspeaker lines. It features 4 balanced analogue inputs, 4 Dante/AES67 digital inputs and outputs, 2 balanced auxiliary outputs, and a flexible 4x 6 digital matrix.

Its comprehensive DSP includes input and output parametric equalization, graphic output equalization, crossovers, delay, and configurable peak and RMS limiters. The built-in web application provides intuitive configuration, control and monitoring of the amplifier. Two Ethernet ports with integrated switch functionality allow network daisy-chaining and provide access to control, Dante/AES67 audio transport and remote management.

HALO 4B300 also supports customizable user control panels and integration with EclerCLOUD and the PULSO digital control panel series.
