The desktop marine public address (PA) amplifier is a core component of the ship's communication system. Specifically designed for the complex on-board environment, it is fixedly installed in key areas such as the wheelhouse and control room in a desktop mounting format. It is mainly used for internal communication among crew members, transmission of navigation instructions, and emergency broadcasting (e.g., abandon ship notices, fire alarms).
Its core features include:
-
Strong Environmental Adaptability: Equipped with salt spray resistance, moisture resistance, and vibration protection performance. Components are made of corrosion-resistant materials, enabling it to adapt to harsh conditions such as high temperature, high humidity, and salt spray erosion during ship navigation.
-
Practical and Precise Functions: Supports direct microphone intercom and amplified transmission of audio signals. Some models integrate zoned broadcasting functionality (capable of directional sound transmission to areas like the deck, engine room, and crew cabins). In emergency mode, it can prioritize cutting off other audio signals to ensure clear transmission of urgent instructions.
-
Compliance and Compatibility: Must comply with the SOLAS Convention and industry standards for marine communication equipment. It can be linked with shipboard walkie-talkies and alarm systems. Some models are equipped with volume adjustment, echo cancellation, and overload protection functions to ensure communication stability.
-
Installation and Operation: The desktop design saves space and allows for easy installation. The control panel is concise and intuitive, facilitating quick mastery by crew members and adapting to the efficient operation needs during ship navigation.
