DETAILS

The Ecler AURA-2B900 is a 2-Channel 2 x 900W Class-D Power Amplifier with low and high impedance compatibility, dual and bridge mode operation, anti-clip system and auto standby.

Stepping up the AURA series with greater output headroom for larger and more demanding fixed installation environments.

The Ecler AURA-2B900 builds on the robust foundations of the AURA series, stepping up to 2 x 900W RMS at 4 Ohm for larger and more demanding fixed installation audio systems. Like all AURA series amplifiers, it has been engineered with the highest levels of robustness and reliability for long-lasting performance in continuous professional operation, combining high-efficiency Class D amplification with a specially designed power supply optimised for electrical consumption efficiency.

Whether deployed in large retail environments, sports and wellness facilities, educational campuses, hospitality venues or corporate headquarters, the AURA-2B900 provides the output power, flexibility and protection features that the most demanding installation projects require — all within the same compact 1RU chassis as the AURA-2B600.

Flexible Output Configuration for Low & High Impedance Systems

The AURA-2B900 supports the same broad range of output configurations as the AURA-2B600 but with substantially increased power output. In standard dual mode, both channels deliver 900W into 4 Ohm loads, 450W into 8 Ohm loads and up to 1000W into 2 Ohm loads. In bridge mode, the amplifier delivers an impressive 2000W at 4 Ohm and 1600W at 8 Ohm for demanding mono applications requiring maximum output from a single channel pair. For high-impedance distributed audio installations, the AURA-2B900 supports both 70V and 100V line operation at 900W, switchable via rear panel dipswitch alongside the dual/bridge and low/high impedance mode selection. An input link to CH1 selector per input allows channels to be linked to the first input for simplified mono or zone distribution applications.

Practical Control & Security Features

The AURA-2B900 retains the same practical control and security features as the rest of the AURA range. Front panel volume control knobs per channel can be locked via rear panel switches, preventing unauthorised level adjustment in public-facing or unattended installations. Each channel can be switched between standard volume control and bypass mode. An auto standby function — selectable from the front panel — automatically places the amplifier into a low-power standby state during signal inactivity, consuming just 2.1W in standby for highly energy-efficient operation. A front panel power on/off switch and dedicated auto standby on/off LED provide clear and convenient system status monitoring.

Comprehensive Protection & Monitoring

The AURA-2B900 is equipped with the same full suite of protection systems as the rest of the AURA series. DC protection, HF protection, short-circuit protection, clip limiter and thermal protection all work together to safeguard both the amplifier and connected loudspeakers during continuous high-power operation. Front panel LED monitoring covers signal present, clip, protect, standby, thermal and link status per channel and per channel pair, with a unit-level power on LED providing clear overall system status. Twin fans provide active cooling throughout sustained high-power use, with a 77% amplifier efficiency rating helping to minimise heat generation and energy consumption.
