Technical Operation:
The Wireless Bass Knob WBK-S consists of two components: the WBK-S Base and the WBK Controller.
The Base is designed to serve as the hub for all connections, including power connections (Positive, Ground, and Remote), as well as RCA input and output for adjusting the audio signal level coming from the head unit.
RCA connections are a car audio standard used in universal wired bass knobs as well, allowing our wireless bass knob to be compatible with every car audio amplifier.
The second part of the wireless bass knob is the WBK Controller, which is used to control the audio signal level through a dedicated volume control IC inside the base module wirelessly.
For communication between the Controller and the Base, a 2.4GHz wireless protocol is used, providing a stable and fast connection at distances of up to 150 feet or more! Besides regulating the audio level, on the controller, you can also monitor the car voltage in real time and customize settings for a better user experience.
During use, if the Controller disconnects from the Base, the audio signal will continue to play normally, and there will be no differences in sound level.
