Overview

For the mid-range market, CSR has created a soundbar platform which allows for a more fully featured design while still reducing system complexity, development time and cost. For a truly immersive listening experience the platform utilizes CSR’s feature rich MAPX™ audio DSP which enables many decoding and post processing options such as Dolby® and DTS™. The MAPX 7 DSP and CSRA65610™ Bluetooth® ROM device featured in the platform design provide a wide variety of input connectivity options. As well as Bluetooth audio streaming and support for the aptX® codec, analog and digital wired audio inputs are supported together with a 2 input/1 output HDMI® interface option. The design also features a Bluetooth connection to a wireless subwoofer containing the CSRA65700™ ROM IC.

The out-of-the-box design from CSR supports a 3.1 configuration which provides speaker drive for left, right and center channels along with the wireless subwoofer output. This arrangement can be readily expanded up to a 7.1 configuration for the ultimate audio experience.

The mid-range platform has been designed with power economy firmly in mind, achieving standby power of less than 500mW. Convenient features for consumers such as wake up from standby and NFC pairing have also been included. The same standby power target is achieved by the entry-level design.
