The Chiayo Electronics Company was founded in 1971 in Chiayi City, Taiwan. In the beginning, the company's main focus was on the manufacturing of Electronic Condenser Microphones (ECM). Chiayo were the first manufacturer to produce this kind of microphone in Taiwan. A few years later Chiayo recorded another first by introducing the first FM wireless microphone in Taiwan. This was followed by pioneering the wireless microphone systems all the way from VHF, UHF, Infrared and fixed frequency to the more modern PLL-Synthesised technology of today.

After more than 3 decades of development, Chiayo is now recognised worldwide as a leading designer and manufacturer of professional wireless microphone systems and wireless portable sound systems. It's also one of the few companies in this field in the world that can boast its own original RF (Radio Frequency) and AF (Audio Frequency) design, from the entry level to the state-of-the-art PLL-Synthesised multi-channel UHF system with proprietary features. The strength of Chiayo lies in its vast experience and industrial know-how in the field. This valuable heritage of technical knowledge, skill and experience have enabled Chiayo to enjoy the confidence of the most demanding customers in the world.

Chiayo believe in producing high quality products and maintaining excellent after sales service, which is an integral part of their business philosophy. Based on this principle, the Chiayo design and manufacturing process are carried out compliant to ISO-9001 standards.

Due to business expansion, Chiayo relocated to its present 6,000 square metre, modern facility in 1997. For the convenience of our international customers Chiayo still maintains an International Sales Office in Taipei. To stay competitive internationally Chiayo built another factory in China. In the future of our product development, Chiayo will apply continued cutting edge technology in wireless microphone systems and wireless portable sound systems to enhance product quality and reliability.

The ACMA's Channel Finder

From 1 January 2015, wireless microphones must not be used in the 694 – 820 MHz frequency range. The main alternative frequency ranges will be 520 – 694 MHz and 1790 – 1800 MHz, with some other frequencies also available.

If you choose to use the spectrum in the 520 – 694 MHz range, you must not cause interference to television and radio services who also use this spectrum.
