Fosi Audio BT20A MAX TPA3255 Class D Stereo Integrated Amplifier with Bluetooth aptX HD, Subwoofer Output, Remote Control, Including 32V/5A Power Supply Adapter
Features:
- Thanks to PFFB technology and dual independent power supplies, this stereo amplifier delivers ultra-low distortion (≤0.003%) and a high signal-to-noise ratio (≥112 dB). It effectively reduces noise and interference, providing clean and detailed audio reproduction.
- Powered by the TPA3255 and NE5532 chips, the BT20A MAX delivers up to 300W per channel. Its optimized design features a built-in ultra-quiet cooling fan, improving cooling efficiency by 30% compared to the PRO version, ensuring stable performance even under heavy load.
- Equipped with the Qualcomm QCC3095 chip and Bluetooth 6.0, supporting LDAC, aptX Lossless, aptX HD, aptX Adaptive, aptX, SBC, and AAC codecs, with a maximum sampling rate of PCM 24-bit/96kHz. Provides a stable, low-latency wireless connection.
- Features dual RCA inputs, a dedicated subwoofer output, and a motorized analog potentiometer for precise adjustments via the included remote control—ideal for a 2.1 home theater audio system.
- Enjoy pure sound in Bypass mode or customize bass and treble in Tone mode. The 12V trigger input enables synchronized power on/off, and the HPF setting optimizes speaker performance.
- Compared to the PRO version, the BT20A MAX features an improved circuit design and a newly integrated ultra-quiet fan that boosts cooling performance by 30%. Specially designed ventilation openings on the top and sides maximize airflow for optimal heat dissipation.
Versatile Functions: Includes bass/treble control and EQ bypass for personalized sound tuning.
