The Sony MXD-D3 is a CD and MiniDisc combo deck released in January 2000, designed for efficient audio recording and playback. It features a high-speed 4X dubbing capability from CD to MiniDisc, enabling quick transfer of music. The unit supports CD-text display, allowing automatic title transfers from compatible CDs. It has a dual line display that can indicate both CD and MD information simultaneously. The device measures 430 × 120 × 290 mm and weighs 4.7 kg, making it a compact addition to any audio setup. The ATRAC encoder/decoder uses the Type-R version, ensuring good audio quality during recording. Key inputs include RCA in, Digital optical (TOSLINK), and CD inputs, while outputs consist of a 1/4 inch headphone jack and RCA out. The MXD-D3 lacks certain modern features like NetMD or Hi-MD support and has a power requirement of AC. Although it is praised for its fast dubbing speed, users have expressed challenges with its remote control interface and some quirks during recording.
