Product:
The new version of the DSP board is equipped with MCU_STM32F103C8T6, AD1938_CODEC decoder board adds a single-chip microcomputer for soft control, you can set the sampling rate and audio interface type.
On-board routines provide input and output IIS/SPDIF (off fiber/coaxial selection) interface;
The factory setting is 192K_TDM format, OUT3/OUT4 are straight-through interfaces, and OUT1/OUT2 are stereo 2 frequency division mode output interfaces.
S1 key input selection; blue light flashes for SPDIF input, red for IN2 analog input. Green for IN1 analog input.
S2 button preset EQ switch, a total of 10 kinds of EQ presets.
S3 key super bass switch, useful in electronic crossover subwoofer channel, open by default;
The three-color LED shows the input channel and working status flashing respectively;
One STM32 single chip is reserved on the board, and the single chip can be used to control the DSP, and the USB/uart/spi port is set aside, which can also be used as a single chip development board.
Potentiometer ADC acquisition for volume control, LED drive example. . .

You only need to connect a minimum of 6 wires to form an audio system with 6 inputs and 8 outputs. It can be used directly with our ADAU1452/ADAU1463/interfaces or ADAU1401 series. It can be controlled by soft control or hard control, or directly configured by DSP The CS42448 is a highly integrated audio codec containing 6 analog input channels and 8 analog output channels, suitable for the design of multi-channel applications in home theater and car audio systems, or DSP electronic 4-way speaker systems. The CS42448 supports the addition of up to eight single-ended or six differential audio input sources, and up to eight single-ended or differential output sources. Highly integrated, multiple audio channels can be passed to the DSP chip for audio processing without the need for external analog-to-digital (A/D) converters. An auxiliary serial input is available for two additional PCM (pulse code modulation) data channels. The inputs are more powerful, enabling audio/video (A/V) sinks that can receive audio from multiple sources. In car entertainment systems, audio input sources can include in-car navigation systems, cell phones, CD/DVD players, and radio tuners. The CS42448 outputs feature Cirrus Logic`s patented Popguard® technology, which eliminates clicks and pops during power switching. Popguard simplifies system design and reduces bill of materials (BOM) costs while enhancing audio. The CS42448 offers advanced performance, design flexibility, reduced BOM cost, and a competitive retail price. This IC is ideal for audio applications requiring wide dynamic range, negligible distortion, and low noise, such as A/V receivers, DVD receivers, and car audio systems.
