The Midas DN4816I StageConnect Interface is a professional audio interface featuring 16 balanced line level combo XLR inputs, designed for expanding audio connectivity in live sound and studio environments. This interface supports multi-channel audio transmission through a single XLR cable, providing seamless integration with other StageConnect devices. It delivers 32 channels of uncompressed PCM audio at 24-bit resolution and 48 kHz sampling rate with latency below 0.05 ms, ensuring high-fidelity audio transmission for professional applications. The interface supports daisy-chaining with other DN48XX series devices, automatically negotiating channels for flexible I/O configurations ranging from 32 inputs to 32 outputs. Power can be supplied via DC input or through the StageConnect connection, with each SC Master providing 18W of power for devices in the chain. The unit is compatible with Ultranet technology, allowing connection to over one million Ultranet-enabled products including P16 monitoring systems, AIR mixers, and Turbosound speakers via a single CAT5 cable. This compatibility enables transmission of up to 16 independent channels of 24-bit digital audio between compatible digital devices. The interface is particularly suitable for connecting wireless microphone receivers, external effects processors, and playback systems, helping to conserve local console inputs while reducing setup time and increasing system reliability. The StageConnect Calculator tool assists with planning system configurations by calculating power consumption, DMX cable lengths, and audio routing parameters. Constructed with professional durability in mind, this interface meets the demanding requirements of touring productions, fixed installations, and recording studios where reliable audio connectivity and signal integrity are essential.
