The AC-BT24 enables Bluetooth® audio streaming to the DM processors and the D-6.1200 DSP Matrix amplifier featuring the Option Port.
First, confirm that the DSP product you are using with the AC-BT24 is running at least version 1.2.0 of the software and version 1.2.1 of the firmware. If your product is running older versions of the software/firmware the processor will not be able to communicate with the AC-BT24.
The way to confirm the software and firmware versions is to first connect the processor (via USB cable) to your computer running the DM Smart DSP software, open the software, login and check the version by going to the Help drop down menu and selecting About.
