A class D audio amplifier is characterized as a PWM amplifier or switching amplifier. The switches are either fully off or fully on, thus significantly minimizing power losses in the output devices. Moreover, efficiencies of 90-95% are possible with class D audio amplifiers. South Korea is a pioneering region across the avenue of technological developments and innovations. Given the substantial deployment of audio amplifier manufacturers in the country, leading enterprises such as Qualcomm have their production plants situated in South Korea. Moreover, the presence of key players, including Samsung and Sony, further bolsters the development of audio amplifiers in the country.

In 2019, South Korea had over 456 passenger cars per 1,000 inhabitants. Although the total number of registered cars is decelerating, it is anticipated to maintain a stable increase. This is mainly attributed to the growing demand for second cars by consumers as well as the expansion of eco-friendly vehicles. The automobile sector, as a result, accounts for the largest buyer of class D audio amplifiers. In addition, several regional start-ups have also developed numerous variations in speakers and subwoofers that are customized in nature. Hence, these factors are expected to augment the class D audio amplifier market growth in South Korea during the forecast period.

The South Korea class D audio amplifier market is segmented into amplifier type, device type, and application. The amplifier type category is further segmented into mono channel, 2-channel, 4-channel, 6-channel, and other amplifier types. 4-channels are typically utilized to power a complete set of door speakers (4 total speakers) in vehicles. They are also bridgeable, facilitating various configurations. Furthermore, a 4-channel amplifier can handle front right, rear left, front left, and rear right, as well.

Other amplifier types include 3-channel, 5-channel, and 8-channel. 5-channel amplifiers are an amalgamation of a monoblock amplifier as well as a 4-channel amplifier, built into the same chassis. This aspect helps eliminate the requirement for elaborate wiring scenarios and multiple amplifiers. Besides, they are an optimal, simple solution for powering 4 speakers and a subwoofer. However, they are relatively more challenging to use for high powered audio applications since 5-channels are typically capable of running around only 600-1000W RMS

Some of the leading companies operating in the South Korea class D audio amplifier market include Analog Devices Inc, Texas Instruments Inc, STMicroelectronics, etc.
