Product overview
The ECLER HALO-4B300 is a 4-channel Class D amplifier with networked DSP, delivering 4 x 300 W at 4 Ω or 8 Ω, with four outputs that can be bridged to drive 70 V or 100 V loudspeaker lines.
It features 4 balanced analogue inputs, 4 Dante/AES67 inputs and outputs, 2 balanced auxiliary outputs and a 4 x 6 digital matrix. The DSP includes input and output parametric EQ, graphic output EQ, crossovers, delay and configurable peak and RMS limiters. A built-in web application handles configuration, control and monitoring, and two Ethernet ports with an integrated switch allow daisy-chaining. User panels, EclerCLOUD and ECLER PULSO digital control panels are supported, all in a 1 RU chassis for desktop or 19 inch rack.
| At 4 Ω or 8 Ω | 4 x 300 W |
| Bridged pair, 8 Ω or 70 V | 600 W |
| Analogue and Dante/AES67 inputs | 4 + 4 |
| 19 inch rack or desktop | 1 RU |
Key features
- 4 amplified outputs, 300 W each at 4 or 8 Ω
- Bridge mode: 600 W at 8 Ω, 600 W at 70 V, 550 W at 100 V per bridged pair
- 4 Dante/AES67 inputs and 4 outputs (2 flows each), 4 analogue inputs, 2 auxiliary outputs
- 2 Ethernet ports with switch for control and Dante/AES67
- DSP: 12-band PEQ on inputs and outputs, 8-band GEQ, crossovers, 1 s delay, peak and RMS limiters, 20 presets
- microSD audio player, events and scheduling, custom user panels
- 4 GPI (0-12 V) and external mute for wall panels and alarm systems
- Energy saving: auto standby per channel and sleep mode; EclerCLOUD compatible
Low impedance or 100 V lines
Each output drives 4 Ω or 8 Ω loudspeakers. Bridging channels 1+2 and 3+4 on the rear CONFIG switches gives high-impedance 70 V or 100 V operation or 8 Ω bridge; invalid set-ups mute the outputs and are reported in the web application.
Network audio and control
NET1 carries control (web application, user panels, third-party control) and NET2 carries control plus Dante/AES67 audio. The Dante/AES67 licence is included and AES67 is enabled by default.
Control for users
Front panel knobs are programmable, WPa wall panels connect to the GPI ports, users control their zones from the ECLER app or a web browser, and EclerCLOUD allows remote monitoring.
