The Green‑GO GGO‑GNM300 is a compact 300 mm electret cardioid gooseneck microphone engineered for seamless integration with MCX and MCXD multi‑channel stations. Designed to deliver precise, articulate speech capture, it combines a sensitive electret capsule with a tight cardioid pickup pattern to focus on the speaker’s voice while suppressing ambient noise, ideal for intercom, paging, broadcast communication, and control-room environments.

With a wide frequency response from 50 Hz to 20 kHz, the GNM300 reproduces speech with clarity and natural presence. Its sensitivity of –42 dB ensures accurate capture of both soft and dynamic vocal levels, while its 110 dB maximum SPL capability provides ample headroom for use in loud technical spaces. The microphone maintains professional audio performance through a 74 dB signal‑to‑noise ratio and operates reliably on 9–52 V phantom power with a low 2 mA consumption.

The streamlined 300 mm gooseneck provides stable yet flexible positioning, allowing users to find the ideal angle for consistent communication. At just 60 g and featuring a 12 mm head diameter, the microphone is lightweight without compromising structural rigidity. A built‑in 3‑pin male XLR connector ensures robust connectivity, while the included windproof foam cover minimizes plosives and optimizes intelligibility. Engineered as part of the Green‑GO intercom ecosystem, the GGO‑GNM300 excels in reliability, sonic precision, and ergonomic adjustability, making it the perfect solution for compact operator stations that demand both performance and durability.
