TINYSINE TSA7800C, 2 x 50W + 100W 2.1 Channels SPDIF Coaxial

TSA7800C 2x50W + 100W 2.1 channels SPDIF+DSP digital amplifier board with a SPDIFBee receiver module. SPDIFBee convert the SPDIF signal to I2S signal and output to the ADAU1701 DSP chip. TSA7800C is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D structure (Texas Instruments TPA3116D2) and 2 channels have 50W power output and another one channel has 100W power output. All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-24V power supply. It can be used to drive any 4Ω or 8Ω passive speakers (subwoofer channel can drive 2Ω speaker). It's a 2.1 channels amplifier board. The channel for subwoofer is 100W mono output (user can change the DSP program to make it become right or left channel). It has a coaxial input connector on the board which can accept different sampling rates digital audio source, from 16bit 44.1KHz to 26bit 96KHz. The highlight point is Analog Devices ADAU1701 DSP chip on board. User can set each channel audio tones separately.
