Public Address System

The PA system consists of equipment such as
microphones, power amplifiers, speakers, and
distributors for public purpose broadcasting in
all or selected areas, and provides emergency
broadcasting and notification broadcasting
functions including fire broadcasting.

NTEC System

New system that can be controlled by network

Karak Electronics' NTEC system is a new broadcasting system designed to suit each purpose in various buildings such as apartments, complex buildings, manufacturing facilities, and educational facilities based on the nation's best technology accumulated over 40 years.


This system meets the fire safety standard (NFSC202) of the emergency broadcasting system through interlocking with the fire receiver and protection of line short circuits, and multiple broadcasting is possible by reflecting the audio matrix structure.


In addition, it is possible to configure a centralized configuration through serial communication and a local area RX/TX distributed system through PLC (Power Line Communication). For user convenience, the web browser control method provides an environment that can be easily used not only in the management room but also remotely according to the user's needs.

Various functions according to product configuration

NTEC adds higher reliability

Basic configuration of NTEC


Economical, concise, and easy to expand peripherals, it provides an optimal operating method for your needs.

External equipment connection


It is possible to transmit/receive various signals and voices to external facilities and broadcasting systems through NEI42, which acts as an interface connected to the main control device, NMC44.

Call station operation


It is possible to broadcast the sound source by selecting the broadcasting area through the call station remotely.

Control multiple audio sources


Multiple audio sources can be integrated and controlled through the main control unit. This allows detailed control such as play/pause/turn over, volume, and USB/CDP/RADIO sound source type selection.

Basic configuration of NTEC


Economical, concise, and easy to expand peripherals, it provides an optimal operating method for your needs.

Switchover of main controller


When a system error of the main controller is detected, the switch to the spare unit is automatically performed through the NEX44, and additional power protection functions are added to respond to continuing broadcasting in case of emergency.

Spare amplifier operation


Through the NFD81, the power amplifier failure can be checked in real time, and the problem power amplifier can be automatically converted into a spare power amplifier to continue broadcasting operation.

Power optimization


From the development stage, NTEC was designed to optimize the DC power supply and improved the reliability of the broadcasting system through a more concise and faithful basic design.

Web browser remote control


Broadcasting system can be controlled through web browser from management room as well as remotely.

TTS(Text To Speech)
 + Reservaion


If you enter the content you want to broadcast in text and reserve a time, it will be broadcast at the reserved time.

Fire receiver interlocking


It is possible to quickly transmit an evacuation broadcasting through interlocking with P-type and R-type fire receiving equipment.

Expandability through digital communication


It supports both centralized configuration and local area distributed configuration enabling broadcasting from small buildings to large complexes.

Multiple Broadcasting


Broadcasts can be sent separately to areas used for different purposes within a building.

Macro function


Broadcasting zones and contents can be stored in macro buttons, allowing you to broadcast easily at the touch of a button when needed.

Emergency bell interlocking


 By interlocking with the emergency bell facility in the building, an voice alarm can be immediately transmitted to the relevant area.

Interlock and control external devices via GPIO


It can be linked with external devices through data and dry contact input/output, or broadcasting by controlling external devices.
