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 pre-set 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.
