POT1 adjusts the relative gain of CH1 based on the total gain. POT3 is used to adjust the CH2 output channel, and POT4 is used to adjust the total gain. When JAB4 is used in 2.1 mode, you can configure any output channel as a 0.1 low channel. The function of the potentiometer will change automatically. If you want to use JAB4 in 0.2 mode, you need to set the output mode and frequency in PCUI. In hardware control mode (potentiometer), JAB4 does not support configuration as 0.2 mode. 3.HPF refers to high-pass filter, and BPF refers to band-pass filter. When CH1 (CH2) is used as stereo output, POT2 (POT3) functions as a high-pass filter; when CH1 (CH2) is used as a single-channel output, POT2 (POT3) functions as a band-pass filter.

work.\u003cbr\u003e\nAnswer.\u003cbr\u003e\nBluetooth indicator light is regular blinking when it works normally, if it is long lit or not lit, there may be a problem with the Bluetooth module, you can contact customer service to deal with it.\u003cbr\u003e\n\u003cbr\u003e\n2, the phone can be connected but notebooks or desktops are not connected.\u003cbr\u003e\nAnswer.\u003cbr\u003e\nIf the phone can connect and play music, it means that the bluetooth amplifier board is not a problem, it may be the computer bluetooth driver problems, the version is too old or there is a file is lost, it is recommended to uninstall and then install the latest version of the driver from the new.\u003cbr\u003e\n\u003cbr\u003e\n3、Volume up sound lag, intermittent, volume down can be normal playback.\u003cbr\u003e\nAnswer.\u003cbr\u003e\nOne of the reasons: the power supply power is too small caused by the voltage or current is too low reason three: if the power supply is not a problem, it is possible that the power of the speaker is too small, such as the output of 5W, but connected to a 1W speakers, the volume is turned up, the phenomenon of lagging, and there is the possibility of burnt out the speakers.\u003cbr\u003e\n\u003cbr\u003e\n4, too much noise when playing music, or not playing music also has a bottom noise.\u003cbr\u003e\nAnswer.\u003cbr\u003e\nThe role of the amplifier board is signal amplification, the main source of noise is the environment of the radio clutter generated by the amplifier board amplification, so there is a little noise is normal, if the noise is too large, you can change the power supply test, or change the speaker test. If there is still noise, contact customer service to send back for testing, replacement or repair.\u003cbr\u003e\n\u003cimg referrerpolicy=\"no-referrer\"
