Standard CMP31W White Second Station Microphone

The Standard CMP31W White Second Station Microphone is a remote control solution built for boaters and mariners running Standard Horizon fixed-mount VHF radios with remote capability. After years on the water, any serious skipper knows that efficient bridge management—especially during critical communications—depends on quick access to radio controls from multiple locations. This second station microphone extends that capability to helm positions, cabin areas, or engine rooms, eliminating the need to leave the helm to adjust frequency, volume, or DSC functions.

Built with a full dot-matrix display and programmable keys, the CMP31W delivers straightforward operation in demanding marine environments. The white faceplate suits modern helm layouts and integrates seamlessly with Standard Horizon's ecosystem. The microphone enables complete functional control—power on/off, channel selection, volume adjustment, and all DSC calling and acknowledgment features—from a secondary location without compromising radio performance or signal integrity. At 2 lbs, it installs with minimal weight penalty and mounts easily in existing dash or console openings.

This microphone is ideal for larger vessels, commercial fishing operations, and cruising boats where crew members need independent radio access during normal watch-standing or emergency response. Compatible with all Standard Horizon VHF radios featuring remote control protocols, the CMP31W works best on installations where the main transceiver is mounted below decks or in an engine compartment. Installation requires a compatible Standard Horizon fixed-mount VHF radio and standard marine-grade cabling; consult your radio's manual for wiring specifications and remote-capable model confirmation.
