The Behringer SD8 I/O Stage Box is a professional audio interface for live sound applications featuring 8 remote-controlled Midas microphone preamps that provide transparent audio recording with low noise and high headroom. This stage box includes 8 balanced outputs for flexible signal distribution to mixing consoles or further processing equipment. It integrates AES50 network connectivity for high-speed, low-latency digital audio transmission over standard Cat5e cables, enabling integration with compatible digital mixing systems. The built-in ULTRANET Personal Monitoring Hub allows up to 8 musicians to individually control their monitor mixes via compatible Behringer personal monitoring systems. With a robust steel housing, the SD8 measures 483 mm in width, 44 mm in height, and 260 mm in depth, weighing 2.8 kg for portable yet durable performance. The device operates on 100-240 V AC with automatic voltage selection and consumes about 15 W. All connections use professional XLR and TRS sockets, with AES50 ports supporting cable lengths of up to 100 meters. The Midas-designed preamps offer 60 dB of gain with precisely stepped controls, while the analog-to-digital conversion delivers 24-bit resolution at sample rates of up to 96 kHz. This stage box serves as a reliable frontend solution for recording multiple audio sources in venues, places of worship, or broadcast environments where consistent audio quality and network integration are essential.
