IS2083 Bluetooth® Audio Application Design Guide

PublishTime：2021-10-22

Microchip’s Multi-Speaker Bluetooth Audio solution utilizes Microchip proprietary technology to connect a master speaker to one or multiple slave speakers through a modified Bluetooth protocol. Multi-Speaker functionality is implemented using Microchip’s IS2083BM device. One (master) speaker can either be connected to a Bluetooth-enabled device (smartphone, tablet, laptop, etc.) A master/speaker can be connected to a device (phone or tablet) over Bluetooth or AUX-in jack, and re-transmit either of the two audio sources to one or more speakers acting as a slave.
Multi-Speaker solutions can be achieved using Class 1 BM83 modules, which allow for extended range. This is a widely used technology for applications such as PA conference systems or wireless audio throughout indoor or outdoor.
Multi-Speaker can be provisioned to Concert mode (two or more speakers) or in Stereo mode (two speakers). For more details, refer to “Demo Setup” and “Firmware Capabilities/Features”.
Figure 1 illustrates a typical Concert mode application where the master speaker is connected to a Bluetooth-enabled device.
Figure 2 illustrates a typical Concert mode application where the master is connected to a Bluetooth-enabled device through AUX-In.
Figure 3 illustrates a typical Stereo mode application where the master is connected to a Bluetooth-enabled device.
Figure 4 illustrates a typical Stereo mode application where the master is connected to a Bluetooth-enabled device through AUX-In.
