IA 202D

Whisper-quiet, efficient and easy to use

The necessary power is provided by two 2-channel Class D power amplifiers optimally tuned to the I-Line column speakers – the IA 202D with 2x 250 W at 8 Ω and the IA 402D with either 2x 200 W at 8 Ω or 2x 400 W at 4 Ω. The built-in 24bit/48kHz DSP processor supplies all I-Line speakers with customised and precise filter, EQ and limiter settings. A rotary push-button on the front panel conveniently controls preset speaker presets, delay and other functions. This ensures fast, uncomplicated and carefree system setup and tuning. Both amplifiers operate the speakers remarkably quietly – made possible by a sensor-controlled fan, an aerodynamically optimised front to back airflow, and a very low idle power. Ideal for quiet environments! The I-Line amplifiers are equipped with the three most common analogue input and output connectors. 2-channel XLR inputs with link outputs in conjunction with Phoenix MSTB 3-pin inputs cover the majority of all input requirements. Maximum flexibility at the outputs is provided by 3x Neutrik speakON® connectors in parallel to 4-pin Phoenix MSTB connectors.



IA 202D power amplifier is equipped with 3 most widely used analog input and output connections in professional audio. 2 channel XLR inputs with link outputs together with Phoenix MSTB 3-pin inputs will cover most of the input needs. Outputs are equipped with 3x Neutrik speakON® connectors in parallel with 4-pin Phoenix MSTB connectors for maximum flexibility.


24bit/48kHz DSP processor provides all I-Line speakers with correct and precise filter, EQ and limiter settings. As always – good sounding and well protected speaker systems are the ultimate aim of the SE AUDIOTECHNIK engineering team. Built-in speaker presets, EQ control, delay and other features allow for an easy, cost-effective and quick system setup and tuning.
