The Tinysine 1 x 200W Bluetooth+DSP Mono Audio Amplifier Board - TSA7550B(Apt-X) - PCB Antenna is a sophisticated audio solution featuring an AudioB plus Bluetooth module with Apt-X support. This amplifier board is designed with a class-D architecture based on the TDA7498E, delivering a powerful 200W mono output. It is compatible with a range of passive speakers, including 3Ω, 4Ω, and 8Ω, and can be powered by a DC14V-39V power supply.
The board integrates a smart cooling system, ensuring the fan operates only when necessary to minimize noise. It supports seamless pairing with mobile devices or computers, appearing as "TSA7550B" without requiring a PIN for connection. A notable feature is the ADAU1701 DSP chip, which allows users to customize audio tones and frequencies. The board comes with a default DSP program and offers flexibility in audio output settings, including full frequency or low pass options via a switch port.
Additionally, the TSA7550B supports Apt-X and TWS, enabling wireless audio streaming to two paired amplifier boards. It incorporates advanced protection features, including over/under voltage, over current, and over temperature safeguards, ensuring reliable performance. Note: Ensure proper handling to avoid exposure to extreme temperatures or electrical hazards.
