HALO series / Networkable Amplifiers

HALO-2B300

Name: Ecler HALO-2B300
Brand: Ecler
SKU: HALO-2B300

HALO-2B300 is a 2-channel Class D amplifier with networked DSP, delivering 2 × 300 W in low-impedance mode at 4 Ω or 8 Ω. Its two 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 4 × 4 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-2B300 also supports customizable user control panels and integration with EclerCLOUD and the PULSO digital control panel series.
