Green-GO Quad 4-wire Audio Interface

The Green‑GO Quad 4‑Wire Interface bridges legacy analogue intercom and line‑level audio directly into the Green‑GO IP ecosystem with four independent ports, each built around a dedicated XLR3 line input, XLR3 line output and a D‑Sub9 GPIO for external call, cue and control logic. Every port can be configured in seconds from the bright TFT display and push‑encoder, running either as a full user‑based Green‑GO engine with routing, calls and cues, or as a general‑purpose line in/out for program audio, show relay and announcements. Dual EtherCON ports provide a built‑in 10/100 Mbps switch for effortless network integration, while local non‑volatile memory safeguards intercom routing, device setup and user preferences for robust, matrix‑free operation. Power is as flexible as the workflows it enables, with IEEE 802.3af PoE over LAN or an optional 12 VDC input, keeping typical consumption under five watts. Housed in a compact 19‑inch, 1U chassis measuring 485 × 160 × 45 mm and weighing 2.45 kg, the Q4WR is engineered for tours, broadcast trucks and installed venues that need rock‑solid audio interchange between analogue 4‑wire infrastructure and modern Green‑GO networks. From tying in a third‑party 4‑wire matrix to injecting remote program feeds via a Green‑GO bridge, the Quad 4‑Wire Interface turns complex intercom topologies into a clean, scalable IP workflow.
