※ In a nutshell, this is a power amplifier that packs a lot of power into a small body. No USB-DAC (A separate USB-DAC is required to connect to a PC or smartphone via USB) 【Features】 ● 1mii BS08+ 100Wx2 Multi-input Power Amplifier ● Includes a 144W power supply for full power output 【Specifications】 ● Type: Class D mini power amplifier ● Output: 100Wx2 (with 24V power supply / 3Ω speakers) + Output for active subwoofer (line output) ● Power Supply: DC 12-24V ● Inputs: Line input (RCA) SPDIF Coaxial digital Bluetooth 5.0 Supported codecs: aptX/aptX-HD/SBC ● Amplifier Chip: TPA3116D2x2 ● Bluetooth Chip: Qualcomm QCC3031 ● The variety of input types, Bluetooth 5.0, and aptX-HD codec support are great features. ● The unit is very compact, but the power supply is large due to the high power output (see photo). 【Power Supply】 ● Switching type ● Input: AC 100-240V The unit's input is a 3-pin (so-called Mickey Mouse) type, but the AC cord is Japanese specification, with a separate ground wire. ● Output: 24V/6A (Confirmed to work when connected to the main unit) 【Current Condition】 Fully functional Includes original box Simple manual printed on the inside of the box No noticeable scratches (see photos). Has not been opened internally. Purchased on Amazon in 2022 (power supply purchased separately on Amazon at the same time) The power supply was replaced with one that provides full power output. The SPDIF interface cover is missing (see photo), but there are no particular issues with use. Selling because I purchased a new amplifier. ※ As of September 2024, the current BS08 model available in Japan is a model that omits the subwoofer output and SPDIF input/mini-jack input. ※ I am not considering price reductions, but I change the price periodically.
