AtlasIED 1522AIOLR 2x2 CobraNet Audio Module with DSP and Control I/O

The IED1522AIOLR is a versatile 2-input, 2-output CobraNet audio interface engineered for seamless integration into professional sound systems. It converts two balanced mic/line analog inputs into CobraNet digital audio while simultaneously decoding two CobraNet channels into balanced line-level outputs. Ideal for expanding existing CobraNet systems, this module offers rich control and processing capabilities.

Featuring individually selectable 48V phantom power, software-adjustable input/output levels, and built-in DSP—including parametric EQ, delay, and compander/limiter—the 1522AIOLR is suitable for precision audio environments. With four opto-isolated GPIO inputs and four relay outputs, it also supports external triggering and control. The unit is powered via IEEE 802.3af PoE and supports redundant CobraNet connectivity.
