The ECM-600H is a complete professional audio power amplifier module. The module contains power transistor drive electronics, control and protection circuitry. Only a power supply, decoupling capacitors and output filter (optional) must be added to produce a stand alone professional audio amplifier. The module is optimised to drive a 4 load (16, 8 and 2 optimised versions are available). Modules can be ganged together to produce a stereo amplifier. For higher power applications the ECM-600H/SL slave module can be linked to the power amplifier to increase the drive capability.
