Omnitronic A-3603

The A-3603 produces enough power to supply large speaker system with up to a maximum of 3600 watts, 4 ohms (2000 W sub and 2 x 800 W tops). Enough potential you can use in clubs, lounges, restaurants, dancing schools and fitness studios and the like.

Set the frequency between the tops and subs with the inbuilt crossover. It also features a bypass function, which enables you to connect ahead a DSP speaker management system. You can as well switch from 2 stereo input channels to 3 separate channels. Save weight when you have to move it and save space when you mount it - the Class D construction and the switching power supply technology help you to do so.
