Electronic Engineering Team I

Electronic Engineering Team I is the hard-core design and engineering team for high wattage power amplifiers. This 5-member team led by Mr Teddy Chiang has created all of the new 70/100 high voltage audio distribution amplifiers, multi-zone multi-function power amplifiers, and high power distribution amplifiers with a range of up to 2000 watts including in a 1U format.

Mr. Teddy Chiang
Director of EE Team I

Teddy loves to design audio amplifiers. He started his career in designing loudspeakers in 1998, at which point  he was assigned the tasks of engineering car audio amplifier and electronic crossover between 1989 and 2002. He has become expert in Class-D Audio Amplifier and this is his passion today.

Mr. Chiang is guy very humble man but he is absolutely full of design ideas. Keiga has several clients who insist on using only his designs. He can discuss design philosophy and run diagram with clients in English and provide solution options and advice for creation of unique products.

His creations in Class-D Amplifier Carrier Cancellation, Thermal-flodback Amplifier Power Control, and DSP controlled Thermal Management System has ellevated Keiga machines to high levels of performance.

He graduated from St. John’s University with Electronical Engineering major.  Other than table tennis, his hobbies are all involved with audio amplifier engineering.  He is an avid music buff and he enjoys playing with electronics and test instruments to sort out his ideas.


Mr. Phil Yao Tzu Kang
Sr. Electronic Engineer

Phil holds an Electronic Engineering degree specializing in electronic communication devices from Chien Hsin University of Science and Technology and has designed several award-winning PROTON car audio-video systems prior to joining Keiga. His knowledge and experienced in designing layout and circuit boards were the drivers in creating several key Keiga products.

Listening to music is his number one hobby, but if you like Chinese Kongfu, he would love to practice Tai Chi and Dharma Health Qi Gong with you.  He is our Renaissance man!


Mr. Kevin Sung
Sr. Electronic Engineer

Kevin holds an Electronic Engineering degree from China University of Science and Technology and has been in production and management engineering for audio and optical devices for years.

He is the go-to guy for technical and engineering transfers between our Taipei office and China factories. His devotion to electronic design and trouble-shooting has earned  him the highest respects from both design and production engineers everywhere.  Numerous amplifier products has been successfully and quickly produced due to his diligence spending nights and days in the factory converting engineering samples to mass productions.

Music, ball games, table tennis, and studying all electronic and engineering are his hobby and kept the highest 205-day record working and living at factory over 18 months.


Mr. Eric Chen
Electronic Production Engineer

Eric graduated from Tamkang University Department of Electrical Engineering in 1999 and studied post-graduate degree in Electro-Acoustic designs.  He stations in our Taichung factory but travels frequently to Taipei office in designing, testing, and documenting products’ production processes.

He found his enjoyment from sports (badminton, softball, baseball, etc.) and classical music.


Mr. Jacky Lin
Electronic, ID and Mechnical Specialist

Jacky likes to problem-solving. His educational background is in Electronic Engineering, but he also shows significant talent on mechanical structure engineering and industry design.   He is extremely thoughtful in laying out electrical circuitry and collaborates extensively with all of other engineers. You can find him always in the lab testing and creating something electronic and mechanical for the projects assigned to him.

His interests are pretty diversified, movie, music, sports, hiking, art, and dancing, you name it.
