IP Audio Input Converter

The Inter-M NAI-1104 IP Audio Input Converter is a high-performance, rack-mountable audio interface designed to integrate analog audio sources into IP-based public address systems. Ideal for facilities requiring flexible and scalable audio distribution, the NAI-1104 converts up to four analog audio inputs into AoE (Audio over Ethernet) digital signals for seamless transmission over a standard IP network.

Engineered for compatibility and space efficiency, the NAI-1104 features a 1U rack-mountable design, allowing it to be easily installed in existing audio systems without taking up excessive rack space. It supports both AC (120~240V) and DC (+24V) power input, offering installation flexibility in a wide range of environments, from corporate buildings and schools to transportation hubs and industrial facilities.

This IP audio converter supports 4-channel analog input, with selectable MIC (-60dBV) and LINE (0dBV) sensitivity. It provides high-quality audio with low Total Harmonic Distortion (THD)—less than 0.04% for LINE input and less than 0.2% for MIC input—and maintains a wide frequency response (20Hz~20kHz) for clear, full-range sound reproduction. The signal-to-noise ratio exceeds 70dB for LINE and 65dB for MIC, ensuring excellent audio clarity.

The NAI-1104 also features 4 contact inputs, allowing for seamless integration with external control devices or triggers such as fire alarm systems or automation controllers. Network communication is handled through a 100/1000Base-T RJ-45 interface, supporting communication distances of up to 100 meters.

Whether expanding an existing PA matrix system or building a new AoE-based infrastructure, the Inter-M NAI-1104 provides reliable, high-quality audio input conversion that empowers professional-grade audio distribution and control.
