SE-Audiotechnik – IA 402D Poweramp


Poweramp 19″, 2HU,2 x 400 W @ 4 Ω

I-Line offers two 2-channel class-D power amplifiers with switching mode power supply.

IA 402D provides 2x 200 Watts at 8 Ohms or 2x 400 Watts at 4 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.
