Digital amplifier

[INQ. NO. 1502E17] Karak Electronics was established in 1977, and specializes in the audio, video, security and PA (public address) system business.

Over the past 30 years, Karak Electronics has focused on the development of highquality and innovative products in the audio and video field, and was designated as a promising medium-sized enterprise by the SMBA (Small-Medium Sized Business Administration). Moreover, the products developed and manufactured by Karak Electronics are distributed domestically through more than 50 dealers, and internationally through over 30 foreign distributors.

Karak Electronics’ digital amplifier Prodigi Series are OTL, in other words, output transformer-less amplifiers. They can be automatically converted into DC24V in case of power failure. Also, the Prodigi Series adopted OTL SEPP circuit to provide high-power output with less space. Compared to the existing amplifiers, the Prodigi Series are efficient in reducing the installation space. The highefficiency is based on Class-D amplification using the PWM method, and is lightweight thanks to its use of SMPS technology and SEPP circuit. The output DC is embedded with protection circuit for checking and preventing overcurrent and overheating, and remote controlling is possible through the power control terminal.

The portable PA system developed and manufactured by Karak Electronics is used for the communication and exchange of information. That is one way of doing multiple passes of the information of limited scope and space for people to target large-scale residential facilities so it is essential to install this system in the public facilities, transportation aviation facilities, buildings, commercial facilities, etc. The product is available embedded in the wall or by hanging on the wall. Main materials of the portable PA system are aluminum and plastic, and the portable PA system, wall mount series are provided in white color.

To enable continuous development in technology, Karak Electronics established the affiliated R&D Center, to fully utilize the developed IT infrastructure to develop the newest concept of PA system for convenience in use and to provide flexibility to the extend system. Through the affiliated R&D Center, Karak Electronics developed several technologies and products, including the public address (PA) system, APT emergency system, touchscreen system, digital video recorder, U-SOTEC system, 5-Zone mixer amplifier, and many others.

Karak Electronics registered and acquired numerous patents for its technologies and products, including the patent on equipment to fasten the speaker, digital PA system, illegal trespassing sensing system and the method, touch screen system, multi-date with single cable transmission and reception system, and many others.
