The High-end Soundbar Example Design utilizes CSR’s MAPX™ 8-Series audio processor and BlueCore® CSR8670™ Bluetooth® Chip (supporting aptX®), as well as an HDMI® Chip, NFC Tag and LCD display.

CSR’s MAPX 8-Series is a high performance, integrated audio system-on-chip (SoC). MAPX integrates 3 DSP cores, high quality audio inputs and outputs (ADCs/DACs/PWM), multiple digital inputs and outputs (SPDIF/I2S), USB host, I2C, SPI and UART interfaces. MAPX drives the CSR8670 Bluetooth device over UART and covers the system, LCD display and HDMI chip control.

The High-End Soundbar example design takes advantage of CSR’s Subwoofer Audio Transfer (SWAT) technology. This protocol and control mechanism allows the Soundbar and Subwoofer to establish a high quality low latency and low frequency wireless subwoofer link.The Wireless Subwoofer Example Design PCB is centred around CSR’s cost effective, dedicated Subwoofer Bluetooth device, CSRA65700™.

The evaluation experience starts straight out-of-the-box, with all kit components being pre-configured with default settings. Customisation of the platform is achieved using CSR provided software and configuration tools.
