MRC

MRC - MRC Inc. (MRC) was established by Eui Joong Hwang (1927-2016) in 1961 in Busan, Korea. MRC manufactures internal communication and broadcasting equipment for marine applications, such as public address systems, auto telephone systems, talk-back systems, marine clock systems, and communal aerial systems for several kinds of vessels. MRC occupies around 75% of the Korean shipbuilding market, and exports internal communication systems to Japan, China, Taiwan, Singapore, Vietnam, India, and countries in the Middle East. MRC is the long-established company in the market of the internal communication systems for vessels in Korea, and it has successfully become one of the world’s leading companies in this field. Since 1992, MRC supplied its originally designed communication systems to more than 8000 vessels and offshore platforms. MRC, located in Busan, is composed of three factories and one office building with 140 employees. We work hard to offer safe navigation of ships to our customers, and we hope to get their ultimate satisfaction.

PA/GA System
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.

The PAGA system abides by the following regulations:
a) International Electro-Technical Commission (IEC)
b) International Maritime Organization (IMO) SOLAS
c) Nautical Safety (Rules for the Classification of Ships, DNV)

This system was tested at the IEC60945 standard and approved for CE by DNV. The Type Approval was done from Lloyd Register, CCS, and DNV.

Loudhailer
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.

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).
