How to Change the Bluetooth 5.0 EQ Settings

There is an in-built equalizer in Tinysine Bluetooth 5.0 module. If you have the CSR USB-SPI programmer, you can change the equalizer settings by yourself. TSA6175 module uses the CSR8675 Bluetooth chip. It needs a new version software to change the EQ settings. This tutorial will teach you how to set it.

 

Hardware and Software required:

Step 1:

Connect the CSR USB-SPI programmer and Tag-Connect line with an AudioB Plus convert board, then connect CSR USB-SPI to your computer by a mini USB cable, and windows will auto-detect it and install the drivers.

Step 2:

Connect TC2050-IDC-NL’s connector to the AudioB5 programming port. You need to locate the single steel alignment pin of the connector into the single hole of the PCB footprint, then press down softly to engage the spring-pin contacts. Make sure the first 6 pins have good contact with the corresponding pads. Then the blue LED and the red LED will flash alternately.

 

Step 3:

Let your smartphone get connected to the Bluetooth module and play the music. You can hear music out from the speakers. And then you can open the “CSRA64xxx Universal Front End” software.

Step4:

DSP->Connection. Select USB SPI and connect it.

Step5: Click “Monitor DSP” button.

Step6:

There are many settings that can be changed on the following page. Here we click “User PEQ” to enter the EQ value setting page.

Step 7:

In the settings page, Unclick the Flat option. Select “Bass Boost” in the Presets. Then click the “Apply” button. You will hear the Bass boost works immediately. You can also try other options.

Step 8:

Click “Download Params” to store the new settings to the Bluetooth module. Then you can remove the programmer and use the Bluetooth audio amplifier with new EQ values.

How to pair the remote with TSA1200

TSA1200 has a dedicated remote control, but if the remote control is broken or you want to use your own remote control, this tutorial will teach you how to pair.

Note: The remote control used must meet the carrier frequency of 38KHz and support the NEC standard.

Hardware and Software required:

  • audio amplifier board
  • connection cable

How to pair remotes
