The Ecler AURA-4B900 is a flagship 4-channel Class-D power amplifier designed for large-scale commercial audio installations requiring high output, flexibility, and long-term reliability. Delivering 4 x 900W RMS output, it provides exceptional power density within a compact 1U rack format, making it an ideal solution for multi-zone systems where performance and efficiency are critical.
As part of Ecler’s advanced AURA Series, the AURA-4B900 combines high-efficiency amplification, dual impedance compatibility, and installer-focused features, enabling scalable system design across hospitality, retail, education, and corporate environments.
The AURA-4B900 delivers 900W per channel at 4Ω across four independent outputs, providing a total system output capability of up to 3600W.
This makes it particularly suitable for:
The high output per channel ensures consistent audio performance across extended speaker runs and multiple zones.
With four independent channels and four analogue inputs, the AURA-4B900 enables flexible multi-zone system design. Each channel can operate independently or be linked to a common input, simplifying mono distribution or system expansion.
This makes it ideal for:
Its multi-channel architecture reduces the need for multiple amplifiers, saving rack space and simplifying installation.
A key advantage of the AURA-4B900 is its dual impedance capability. It supports:
Selectable via rear panel switches, this allows the amplifier to be used across a wide range of system types.
This flexibility enables:
The AURA-4B900 supports bridge mode operation, allowing channel pairs to be combined to deliver up to 2000W into a single output.
This is particularly useful for:
This adaptability allows the amplifier to support both distributed and high-output system designs.
Utilising Class-D amplification technology, the AURA-4B900 delivers high output with improved efficiency and reduced heat generation.
With efficiency levels of around 80%, it ensures:
This makes it well suited to commercial environments where systems operate for extended periods.
The AURA-4B900 includes a comprehensive suite of protection features designed for professional use:
These systems ensure stable and reliable operation while protecting both the amplifier and connected loudspeakers.
An automatic standby function further enhances efficiency by reducing power consumption when no signal is present.
Designed with installation efficiency in mind, the AURA-4B900 includes:
These features ensure secure installation, easy configuration, and reliable operation in commercial environments.
The amplifier features dual fan cooling, ensuring stable thermal performance even during sustained high-output operation.
This makes it suitable for demanding environments where the system is expected to run continuously.
The Ecler AURA-4B900 is widely used across professional AV installations:
Its high power output and multi-channel flexibility make it particularly suited to large-scale installations.
