Ecler HADA-4B500 4-Channel 4 x 500W Networkable DSP Power Amplifier
DETAILS
The Ecler HADA-4B500 is a 4-Channel 4 x 500W Networkable Class D DSP Power Amplifier supporting low and high impedance loads, with a 4x4 digital matrix mixer, comprehensive onboard signal processing and full TCP/IP network contro.
Delivering 1000W bridged output for the most powerful and demanding fixed installation audio systems.
The Ecler HADA-4B500 is a high-powered amplifier within Ecler's HADA series of professional networkable DSP amplifiers, delivering four channels of 500W Class D amplification for large-scale and highly demanding fixed installation audio systems. Building on the same proven platform as the rest of the HADA series, the HADA-4B500 steps up to a significantly higher output power level whilst retaining the same comprehensive digital signal processing, matrix mixing, network control and protection capabilities that make the HADA series a trusted choice for professional installers and system designers.
Whether deployed across large sports facilities, entertainment venues, educational campuses, corporate headquarters, hospitality environments or large public buildings, the HADA-4B500 provides exceptional amplifier headroom, broad impedance flexibility and the reliability that the most ambitious installation projects demand — all within the same compact 2RU 19" rack chassis as the rest of the HADA series.
500W Per Channel with 1000W Bridged Output
The HADA-4B500 delivers 500W per channel into 4 Ohm loads and 250W into 8 Ohm loads, with a further operating point of 360W at 2.7 Ohm for lower-impedance speaker configurations. In bridge mode, channel pairs deliver an exceptional 1000W into high-impedance 100V or 70V distributed speaker systems, as well as 1000W at both 4 Ohm and 8 Ohm bridge — making the HADA-4B500 a highly capable choice for the most power-hungry low-impedance speaker arrays and large-scale 100V line distributed audio installations. Output mode selection per channel or channel pair is handled via the HADA DSP Manager software for precise and flexible system configuration.
Advanced Onboard DSP via HADA DSP Manager
The HADA-4B500 shares the same advanced DSP engine as the rest of the HADA series, built around a dual-core 64-bit processor with 96kHz/24-bit audio conversion and 113dB dynamic range. Per-channel processing includes parametric EQ, delay, limiter and multiband compressor on both input and output paths, with a 4x4 digital matrix mixer allowing any input to be routed to any output combination for maximum system design flexibility. All configurations can be saved as presets for rapid system recall and deployment. Signal processing latency is an extremely low 500 microseconds from analogue input to analogue output. The HADA DSP Manager application — accessible via Ethernet (100Mbps, CAT5 up to 100m) and an embedded web application — provides a comprehensive and intuitive interface for all device configuration, monitoring and control from a networked computer or control system.
Multiple Control Options
The HADA-4B500 offers the same generous range of control options as the rest of the HADA series. Front panel rotary attenuators provide direct local level control for each output channel. Four rear panel GPI inputs (0–3.3V) enable remote volume control from external control devices, whilst an external MUTE input via dry contact closure allows system-wide muting from fire detection systems and other safety or control devices. Third-party control system integration is supported via TCP/IP, making the HADA-4B500 compatible with a wide range of building management and AV control platforms. A front panel RUN/SLEEP button enables standby mode for energy-efficient operation during periods of inactivity.
Comprehensive Protection & Monitoring
The HADA-4B500 is equipped with the same full suite of protection circuits as the rest of the HADA series, providing total reliability in continuous professional operation at high output levels. DC protection, HF protection, short-circuit protection and thermal protection — with automatic output power reduction at 90°C and full mute at 100°C — safeguard both the amplifier and connected loudspeakers at all times. Per-channel front panel LED monitoring covers signal present, clip, limit, mute and protection status, with additional unit-level indicators for power on, data activity, thermal status and external mute. The temperature-controlled variable speed fan with front-to-back airflow ensures efficient thermal management throughout sustained high-power operation.
