3. This product can improve the clarity of high and low bass and enhance the dynamic effect
4. Built-in miniature potentiometer adjustment, suitable for in-machine modification
5. Single power supply is easy to use
Working voltage: DC5-12V (recommended to use regulated power supply, try not to use switching power supply to avoid interference)
Interface spacing: 2.54mm
The treble adjustment potentiometer has two functions
1: When the potentiometer is adjusted to the left (within the range of 3/1 clockwise), the BBE is straight-through (that is, the bbe function is turned off)
2: The range after the potentiometer is adjusted clockwise by 3/1 is to enable the bbe function, and the potentiometer is used for treble adjustment at this time. In this way, there is no need to add a bbe switch, and the bbe can be controlled on and off by adjusting the tweeter potentiometer, which is more convenient to use.
