Ecler HADA Series of Amplifiers

HADA-4B250

DSP | LoZ and HiZ | 4x250W

Networkable Amplifiers | Reference: CHADA4B250

HADA-4B250 is a 4x250W 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.

4 x 250W outputs @ 4ohms.
2 x 500W @ HiZ (100/70V) in bridge mode.
4 analogue inputs on Euroblock connectors.
4 GPI for remote volume control.
1 External Mute.
Internal matrix mixer and signal processing.
HADA DSP Manager software for device configuration and control.
Third party control via TCP/IP
