HADA series / Networkable Amplifiers

HADA-4B750

Name: Ecler HADA-4B750
Brand: Ecler
SKU: HADA-4B750

Highly Adaptable Digital Mixer

HADA-4B750 is a 4x750W digital amplifier that supports low and high impedance loads. The internal DSP, through the DSP Manager software, allows tailoring the input and output signal through parametric EQs, multi-band compressors, limiters, and delays and each configuration can be saved as a preset. In addition to the software option, input levels can be controlled via the front panel potentiometers, via remote controls using the rear panel GPI, or via a TCP/IP from third party control systems. All HADA series amplifiers include efficient thermal protection, DC protection, over current protection, and HF protection for total reliability in any kind of installation.
