Ecler AURA-4B600 4-Channel 4 x 600W Class-D Power Amplifier - 100V & 2/4/8 Ohm
The Ecler AURA-4B600 is a 4-Channel 4 x 600W Class-D Power Amplifier with low and high impedance compatibility, dual and bridge mode operation, anti-clip system and auto standby.
Delivering the same proven AURA series performance across four independent channels for more complex and multi-zone fixed installation environments.
The Ecler AURA-4B600 steps up the AURA series to four channels of 600W RMS at 4 Ohm, making it the ideal choice for installations requiring independent amplification across multiple zones or speaker groups from a single compact 1RU rack unit. 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 across multiple zones in retail environments, educational facilities, corporate spaces, hospitality venues or sports and wellness facilities, the AURA-4B600 delivers the output power, channel flexibility and protection features that multi-zone fixed installation projects demand.
Flexible Output Configuration for Low & High Impedance Systems
The AURA-4B600 supports the same broad range of output configurations as the 2-channel AURA models but across four independent channels. In standard dual mode, all four channels deliver 600W into 4 Ohm loads, 300W into 8 Ohm loads and up to 800W into 2 Ohm loads. In bridge mode, channel pairs deliver 1300W at 4 Ohm and 900W at 8 Ohm for demanding mono applications requiring maximum output from a single channel pair. For high-impedance distributed audio installations, the AURA-4B600 supports both 70V and 100V line operation at 600W per channel, switchable via rear panel dipswitch per channel pair alongside dual/bridge and low/high impedance mode selection. An input link to CH1 selector per input allows individual channels to be linked to the first input for simplified mono or zone distribution applications.
Practical Control & Security Features
The AURA-4B600 retains the same practical control and security features as the rest of the AURA range across all four channels. 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 2.3W 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 at a glance.
Comprehensive Protection & Monitoring
The AURA-4B600 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 across all four channels. 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 72% amplifier efficiency rating helping to minimise heat generation and energy consumption across the four-channel configuration.
