Samsung Galaxy S9 Makes a Single Outing at MWC 2018 Samsung Galaxy S9 was unveiled at MWC 2018 held on the Feb. 26-March 1 in Barcelona. In particular, this new Samsung Galaxy S series outshone all others since major smartphone makers such as Huawei, LG, and Xiaomi did not release new smartphones for MWC 2018.
The main features of the Samsung Galaxy S9 include the 5.8” (Galaxy S9) and 6.2” (Galaxy S9 Plus) Infinity curved QHD Super AMOLED display, super speed dual pixel camera (OIS, F1.5 / F2.4) and dual pixel camera (S9 Plus) with a resolution of 12 megapixels, 10-nano AP, and 4GB (S9) / 6GB (S9 plus) of DRAM. The Samsung Galaxy S9 will be mounting three different storages: 64GB, 128GB, and 256GB.
Overall hardware specs are not much different from the previous model. Yet, its improved camera functions and enhanced Augmented Reality (AR) functions such as AR Emoji are recognized as impressive. In particular, the camera is equipped with a super-speed dual-pixel image sensor along with a variable aperture capable of switching between F/2.4 and F/1.5, which allows taking brighter pictures in the dark, and dedicated DRAM, thereby providing a super-slow-motion mode that can shoot videos at 960fps (previously at 240fps).
Other features include AR Emoji, an animated emoji created by using one’s selfies that replicates the movements of a user’s face, available via AR shopping provided in collaboration with major brands such as Sephora, and AR live translation to read and translate words from photos.
In addition, intelligent scan that combines facial recognition and iris recognition and Dolby Atmos dual stereo speakers from AKG, a premium audio brand of Harman, are also emerging as successful upgrades on the previous model.
A representative of NH Investment & Securities explained, “Despite its relatively low sales volume forecast, the Samsung Galaxy S9 is expected to be able to bounce unexpectedly. It is because we believe that the competition will weaken due to lack of competition, the return of the replacement cycle of Galaxy S series (in odd numbers) every two years, and Samsung Electronics’ strengthened promotions will be unexpected variables to come.” | Blog Magazine of korean electronics, brands and Goods

Top-quality sound audio system systems

[INQ. NO. 1410E21] Karak Electronics was established in 1977, and specializes in the audio, video, security and PA (public address) system business. For the past 30 years, Karak Electronics had 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.

The 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 for either embedding in a wall or by hanging on a 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.

Top-quality-sound-audio-system-systems The digital amplifier Prodigi Series are OTL, in other words, output transformerless amplifiers. The product can be automatically converted into DC24V in the event of a power failure. Also, the Prodigi Series adopted an OTL SEPP circuit to provide high power output with less space. Compared to the existing amplifiers, the Prodigi Series is efficient in reducing the installation space.

The high efficiency is based on the Class-D amplification using the PWM method, and is kept lightweight by using SMPS technology and SEPP circuit. The output DC is embedded with a protection circuit for checking and preventing overcurrent and overheating, and remote control is possible through the power control terminal.
