Configuring a TinySine Bluetooth amplifier module in Mono mode

The aptX TinySine Bluetooth amplification modules are set by default for stereo output. However, it is possible to switch this output to Mono mode by changing the configuration of the Bluetooth module. Once this change is made, the 2 audio channels (L/R) will be mixed and output on the left channel. This guide details the steps to change this setting.

Only TinySine aptX Bluetooth amplification modules support Mono output.

Connect the connector of the TC2050-IDC-NL cable to the programming port of the AudioB Plus module. To do this, place the metal alignment pin of the connector in the hole provided for this purpose on the PCB. Press gently to make contact between the pins and the contact points. The blue and red LEDs start flashing alternately.
