IA 202D

I-Line offers two 2-channel class-D power amplifiers with switching mode power supply. IA 202D delivers 2x 250 Watts at 8 Ohms. The amplifier is equipped with a digital encoder with push button for DSP preset selection, delay settings, EQ adjustments and more.

Sensor-controlled fan and optimized front-to-back air flow, together with very low idle power consumption, ensure low noise levels for quiet environments at all times. A combination of XLR, speakON® and Phoenix connectors for in- and output ensures maximum flexibility during the installation process.
