Description

The Ecler AURA-2B900 is a high-output, professional 2-channel Class-D power amplifier engineered for demanding commercial audio installations. Delivering an impressive 2 x 900W RMS output, it provides the power, flexibility, and reliability required for large-scale distributed audio and foreground sound systems.

As part of Ecler’s AURA Series, the AURA-2B900 is designed to simplify system design while maintaining exceptional performance across both low impedance and 70V/100V line applications, making it a highly versatile solution for installers working across multiple sectors.

High Power Output for Large-Scale Installations

The AURA-2B900 delivers 900W per channel at 4Ω, providing substantial headroom for larger venues and demanding audio environments.

This level of output makes it ideal for:

• Large hospitality venues such as bars, clubs, and hotels
• Retail environments and shopping centres
• Corporate and conference facilities
• Education campuses and public buildings
• Fitness and leisure venues

For applications requiring even greater output, the amplifier supports bridge mode, delivering up to 2000W at 4Ω for high-power mono configurations.

Dual Compatibility: Low and High Impedance Systems

A key advantage of the AURA-2B900 is its ability to operate across both low impedance (2Ω, 4Ω, 8Ω) and high impedance (70V/100V) systems via rear panel configuration.

This enables:

• Use in distributed ceiling speaker systems
• Integration into existing 100V line installations
• Deployment in traditional low impedance speaker setups
• Hybrid system designs combining both formats

This flexibility makes it suitable for both new builds and system upgrades without requiring additional amplification hardware.

Flexible Dual and Bridge Mode Operation

The AURA-2B900 supports both dual channel (stereo) and bridge mode operation, allowing installers to configure the amplifier based on system requirements.

• Dual mode enables independent operation of both channels
• Bridge mode combines channels for maximum output

This adaptability ensures the amplifier can support a wide range of system designs, from multi-zone distribution to high-power mono applications.

High Efficiency Class-D Amplification

Utilising Class-D technology, the AURA-2B900 delivers high output with excellent energy efficiency and reduced heat generation.

Benefits include:

• Lower power consumption
• Reduced operating temperatures
• Compact 1U rack design
• Reliable long-term performance

The amplifier is engineered with an optimised power supply and power factor correction (PFC), ensuring efficient electrical performance in continuous-use environments.

Advanced Protection and Reliability

The AURA-2B900 includes a comprehensive protection suite designed to safeguard both the amplifier and connected loudspeakers:

• Thermal protection
• Overload and short-circuit protection
• Anti-clipping system
• DC and high-frequency protection
• Auto standby function

These features ensure stable and reliable operation in demanding commercial environments.

Installer-Focused Design and Control

Designed with professional installation in mind, the AURA-2B900 includes a range of practical features:

• Euroblock input and output connectors with locking system
• Input link functionality for simplified signal routing
• Front-panel volume controls with rear-panel locking for security
• LED indicators for signal, clip, protect, and status monitoring

These features allow for efficient setup, secure operation, and straightforward system management.

Cooling and Continuous Operation

The amplifier incorporates fan-assisted cooling to maintain thermal stability during high-output operation. This ensures consistent performance even in environments where the system is running continuously under load.

Ideal Applications

The Ecler AURA-2B900 is widely used across professional AV installations:

• Large multi-zone hospitality systems
• Retail and shopping centre audio
• Corporate and conference AV systems
• Education and campus-wide installations
• Public address and paging systems
• Fitness, leisure, and sports facilities

Its combination of power and flexibility makes it particularly suitable for larger and more complex audio systems.
