Open the upper cover of the AD-66DPRO and take a closer look: the overall circuit layout is obviously more beautiful than the previous generation product, and the chassis circuit board filling ratio is also more substantial and eye-catching. The circuit design of the whole machine is divided into five parts: analog audio signal input board, digital audio decoding and Bluetooth receiving circuit board, main power amplifier circuit board and power supply board , 110V ~ 220V patented dual power management system board, and panel LCD display circuit board.

AD-66D PRO has upgraded a set of phono amplifier input unit circuits that were previously only found on mid- to high-end HI-FI power amplifiers . This is aimed at some nostalgic audio enthusiasts who like to play vinyl records, and the audio market should also It is a new strategy adopted by a large number of different grades of vinyl record players. This unit circuit is also equipped with a phono amplifier mode selection slider, which can select moving magnet ( MM ) or moving coil ( MC) according to the LP record player used. ) There are two ways of phono amplification. It fully meets the needs of this group of enthusiasts and is very user-friendly and practical.
