MRC Various Products
MODEL : MPA-9000 / MPA-7000 / MPA-2000
Public Address system is a marine and offshore PA/GA system. The Public Address System (PA) and General Alarm System (GA) are very important in ensuring the safety of facilities and human life. In particular, this system is designed to respond precisely to emergency situations through the connection with various alarm systems. In explosion endangered areas, an explosion-proof speaker or an intrinsically safe microphone is supposed to operate.-
MODEL : MPA-1100
The MPA-1100 series Loudhailer is a multipurpose device that is used as a ship-to-shore hailer, ship-to-ship hailer, foghorn, audio amplifier, intercom, and/or alarm system. As a loudhailer, it amplifies the sound through the speakers to a 200~400 watt level and adjusts to the desired voice level. If an additional (optional) horn is added to the system, the loudhailer output can be switched to either or both of the hailing horn positions from the front panel control. And the system is designed and manufactured to provide ease of installation and operation with excellent reliability.-

It is manufactured to be a waterproof and dustproof appropriate for the vessel, and adopts the input power supply of 24V DC to deliver communications and signals (bell, lamp, etc.). This system includes the following types: flush, wall, waterproof, portable, and intrinsically safe (used for normal condition or in the area with the possibility of explosive gas in case of accident) types, all of which can be interfaced to the Horn/Bell/Flashing Light, and the Foot Switch.-
MODEL : LC-900 / JB-904/906/908/912 / PS-900
Intrinsically Safe Telephone system is designed to communicate at dangerous locations in the vessel (either at normal conditions or in the area with the possibility of explosive gas in case of accident), as it performs perfectly for the intrinsically safe construction. The structure of this system is carefully manufactured to be humidity, water, shock, and corrosion resistant in consideration of the maritime environment. The quality of voice signal and side tone was improved by adopting a low-noise OP-AMP in the telephone. Noises induced from the voice transmitter were remarkably reduced by using the circuits with high common mode rejection ratio (CMRR).-

The NTP-100 provides secure synchronised timing for ship network system. The NTP Server is the solution for stable and precise timing on your network with GPS via Marine Master Clock System. The MRC (MCS-980) master clock system ensures the synchronization of all IT devices on the same network. Typically, this is done through the network time protocol (NTP) on the active portion of the communications infrastructure. The MRC NTP-100 is based on GPS and Master clock system technology for synchronising to satellites’ atomic clocks. This enables computer networks to synchronise all elements of network hardware and software (including system logs) to the millisecond over LANs and/or WANs anywhere on the vessel.-
MODEL : MSR-9200A / MSD-100
Sound Reception System is a device for the wheelhouse isolated from the outside to pick up the signals clearly coming from other vessels by sensing the sound waves (70Hz-820Hz) outside the vessel. A sound amplifier and speakers are installed in the wheelhouse, and four waterproof microphones are connected to the outside. It is possible to figure out the direction of sound as the speakers in the wheelhouse play the amplified sound from the microphones installed outside. The level of output sound can be controlled and interfaced to the PAGA and Whistle systems.-
MODEL : MMS-100 / MSS-110 / MSS-120
Paging System is a device to enhance work efficiency and safety by facilitating smooth communication between workers in crane operation.
