• With the objective of developing a product that realizes the best hi-fi sound quality, enhances user convenience, has diversified connectivity, and has most functionality relative to the price while not emphasizing on a fancy exterior and demanding specifications, the development of the HUD-mx2 has been completed after a long period of time, adopting a number of high-quality components and utilizing our company’s extraordinary PCB design technology. The HUD-mx2 is capable of processing an optical input (24bits/192kHz) and a USB input (24bits/96 kHz) using only USB bus-power and enables users to enjoy audio playback that offers stronger sound output and higher sound quality by connecting the adaptor provided with the product. Moreover, users can enjoy audio playback from an iPad (with a camera kit) or a smartphone (with an OTG cable) that supports the new USB audio, etc. by connecting to them. Because it supports automatic power on/off and a power saving mode, the HUD-mx2 maximizes user convenience and power efficiency when using the product in the USB input mode.
