The Fosi Audio BT20A MAX is a compact stereo amplifier designed to deliver more power, greater flexibility and improved Bluetooth connectivity. It utilises a Texas Instruments TPA3255 chip and a Qualcomm QCC3095 Bluetooth 6.0 module, with support for high-quality codecs such as LDAC, aptX Lossless, aptX Adaptive, aptX HD, AAC and SBC. <\/p>\n

It features two RCA inputs, a Bluetooth input and a subwoofer output, allowing you to set up a simple yet effective 2.1 system. With a suitable power supply, it can deliver up to 300W x 2 at 4\u03a9 peak power, with 180W x 2 RMS at 4\u03a9, whilst maintaining a compact design suitable for a desk or living room. <\/p>\n<\/div>\n<\/div>\n<\/div>\n
