Modifying Harman Kardon Speaker Settings via Micro-USB: Disable Auto-Shutoff

In this article, we will discuss how to modify Harman Kardon speaker settings, specifically focusing on disabling the auto-shutoff feature, through the Micro-USB interface. The procedure covered here is applicable to various Harman Kardon speaker models, including the Harman Kardon Onyx Studio 5.

Understanding the Harman Kardon Speaker Settings

Harman Kardon speakers come equipped with a range of settings that can be modified to suit user preferences. One such setting is the auto-shutoff feature, which is designed to conserve power by automatically turning off the speaker after a period of inactivity. However, there might be situations where you want to keep your speaker on continuously, making it necessary to disable this feature.

Accessing the Speaker Settings via Micro-USB

To access and modify the speaker settings, you will need a Micro-USB cable, which is typically included in the speaker's packaging. Follow these steps to get started:

1. Connect the Micro-USB cable to your computer or laptop.
2. Plug the other end of the Micro-USB cable into the Micro-USB port on your Harman Kardon speaker.

Identifying the Service Port

Once connected, you will need to locate the Service port, which is typically found within the speaker's settings menu. To do this:

1. Launch a terminal or command prompt on your computer.
2. Run the following command to list the available ports:

    $ ls /dev/cu.*
    

   Note the port name that appears after connecting the speaker. This will be used to access the speaker's settings.

Modifying Speaker Settings: Disabling Auto-Shutoff

Once you have identified the correct port, you can modify the speaker settings using a plain text editor, such as nano or vi. To disable the auto-shutoff feature, follow these steps:

1. Run the following command to open the settings file:

 $ nano /dev/cu.<port_name>
 

Replace <port\_name> with the actual port name identified earlier.

1. Locate the following line within the settings file:

 power_save_time_sec = 1800
 

This line specifies the auto-shutoff time in seconds (1800 seconds = 30 minutes).

1. Change the value to a large number (e.g., 86400 for 24 hours) or set it to 0 to disable the feature entirely.
2. Save the changes and exit the text editor.

Verifying the Changes

After disabling the auto-shutoff feature, it is essential to verify that the changes have taken effect. To do this, simply check that the speaker remains on even after the usual auto-shutoff period has elapsed.
