â– Wired audio mode for pendant-style devices supports music playback using a line-in jack. Enables non
Bluetooth operation in low battery modes or when using the device in an airplane-mode.
â– Support for smartphone applications (apps)
â– The CSR8615 mono ROM solution has undergone extensive interoperability testing to ensure it works with
the majority of phones on the market
16.1.1 A2DP Streaming
CSR8615 QFN enables an A2DP v1.2 stream connection. This enables high-quality mono music streaming where
the left and right stereo streams are mixed.

CSR8615 QFN supports a wired audio mode for playing music over a wired connection. This enables operation
when the battery is too low for Bluetooth operation or in environments where the use of wireless technologies is not
permitted, e.g. airplane-mode.
The CSR8615 mono ROM solution automatically routes the wired audio input to the output when CSR8615 QFN is
not powered.
If CSR8615 QFN is powered, the audio path is routed through CSR8615 QFN, including via the DSP, this enables
CSR8615 QFN to:
â– Mix audio sources, e.g. tones and programmable audio prompts
â– Control the volume of the audio, i.e. volume up and volume down
â– Utilise the 5 band EQ
