IA 402D
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.
Features
Connectivity
IA 402D 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.DSP
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.Specification
