FOSI AUDIO BT20A PRO 48V AMPLIFIER
The Fosi Audio BT20A Pro 48V is a compact Class D integrated amplifier supplied with a 48V/5A power supply for its higher-output configuration. It combines stereo RCA and Bluetooth 5.0 inputs with volume, bass and treble controls, a 3.5mm pre-out and speaker outputs, making it an accessible solution for desktop, bookshelf and compact stereo systems.
TPA3255 CLASS D AMPLIFICATION
The amplification stage is built around the Texas Instruments TPA3255 Class D platform. With the included 48V/5A power supply, this version is specified at 225W × 2 into 4Ω at 1% THD, providing significantly greater available output than the lower-voltage configuration of the BT20A Pro.
RCA & BLUETOOTH 5.0
The BT20A Pro accepts a conventional stereo RCA source or wireless playback over Bluetooth 5.0. Bluetooth supports SBC and AAC codecs and has a specified transmission range of up to 50ft. Bluetooth takes priority when an active wireless connection is present.
BASS, TREBLE & PRE-OUT
Independent bass and treble controls allow simple adjustment to suit the loudspeakers, room or personal preference, with centre positions for neutral response. The rear 3.5mm pre-out can feed an active subwoofer, powered speakers or another amplifier, adding useful flexibility to compact 2.1 and multi-amplifier systems.
SWAPPABLE OP-AMPS
Two socketed NE5532 operational amplifiers can be replaced with compatible alternatives including LME49720HA, MUSES02, OPA2134PA and LM4562. This gives experienced users an optional route for experimenting with the analogue stage while retaining the core TPA3255 amplifier architecture.
