Microphone Unit

The Zenitel Phontech P-8301 MK11 is an external microphone and antenna unit for the P-8301 MK11 marine sound reception system. It helps closed bridge vessels detect relevant external sounds, such as foghorns, bells and gongs, when operators cannot hear them directly.

Main benefits and key functions

Four microphones in an omnidirectional assembly monitor sounds from around the vessel. Zenitel specifies the 70–2100 Hz detection range and digital processing for noise suppression and sound direction determination within the complete system. The unit therefore has a different job from the P-8301 MK11 display: it is the outside sensing element, not the operator panel. For bridge equipment installers, the distinction between the outside sensor and the indoor display is important. Both elements are needed for the detection and presentation functions described by the manufacturer.

Typical applications

P-8301 MK11 is intended for one-person operated closed bridge class ships as part of the Phontech sound reception system. Its ability to collect sound from every direction helps supply the bridge equipment with the information needed to present audible warnings and directional indications to crew.

Connectivity and installation

The microphone/antenna has a 3 m pigtail for system connection. Zenitel describes the sound reception system as self-calibrating, easing setup and alignment. Official documentation lists MED, UK MER, ISO 14859 and IEC 60945-related approvals. Specify it together with the matching P-8301 MK11 main display unit and installation accessories as required.

Specification and purchasing guidance

For installers and specifiers, the P-8301 MK11 should be matched to the host equipment, cabling and operating conditions shown on the project drawings. Keep the model number in the system schedule so future maintenance teams can identify the correct version. Check any optional accessories separately rather than assuming they are supplied with the base product.

Summary

The Zenitel P-8301 MK11 offers a focused solution for its documented role. Its main strengths are the specific functions and compatibility described above, making it a practical choice when those requirements are part of the installation. Order the exact version that matches the system design.
