Info & Guides
NOTE: The CMP31 (black or white) is used on fixed mount Standard Horizon VHF radios. The CMP31 replaces the CMP30 and is fully backward compatible. It has a longer mic cable (24.25 inches), and louder audio than the previous model.

When connected to the MATRIX GX3000S, or the QUANTUM SERIES VHF, this remote station mic controls the 30W PA/hailer functions, whether you're at the Nav station, cockpit, tower or lower helm station.

The RAM3 microphone is supplied with 23 feet routing cable and a waterproof panel mount connector. For the ease of adding an extension speaker, a pair of speaker wires is supplied on the rear of the routing cable so you do not need to pull additional wires.

Additional features include intercom capability when connected to a compatible Standard Horizon VHF. The RAM3 can be extended to up 70 feet using the optional CT-100 (23 Foot) extension cable. The CMP30 RAM3+ is backed by an industry leading 3-year waterproof warranty.
