DUAL TPA3116D2 HIFI Chip Solution: Stereo Dual-channelOutput to Ensure Continuous Serial High-power Operation, THD ≤0.1%. Wide Voltage Input DC: 12-24V;
Treble & Bass Control: If You Are Tired of The Inherent High& Low Bass, Why Not Try The High & Low Control Knob! This Will Make You Feel Like Being In A Movie Theater.
BT and AUX Function: BT 5.0 version, Transmission Distance Is Farther. The Transmission Distance Can Reach 49 Feet In An Open Environment. If your Play Device Does Not Have BT, You Can Also Input Audio Signals Through The 3.5MM Headphone Plug.
Safety Protection: This Amp Board Has Overheat Protection, Circuit Protection, Over-voltage and Under-voltage Protection.
- The power supply of the module is very critical. The user must pay enough attention to the power supply. Otherwise it may not work properly.
- The higher the voltage and the higher the current then the better the output power. It is better to connect 3~4in speaker if user only have 12V 1A power adapter. It is no problem to connect 8~10in speaker if user have a power adapter which more than 19V 5A.
- If the voltage is too low, the sound will be distorted after the sound is amplified.
- If the current is too small, the speaker cannot be driven to work, and the speaker will pull the voltage low, resulting in abnormal operation or poor sound quality.
- It is recommended to use 18V/19V/24V power supply with current above 5A.
- Putting the volume to the maximum may be distorted, affecting the sound quality if input low power adapter such as 9V/12V or 1A/2A adapter.
- Commonly used speakers are generally 4ohm~8ohm.The speaker no need distinguish between positive and negative polarity.
- It can also work properly if the speaker has low power such as 20W~50W. But it needs connect to low power adapter such as less than 15V to prevent damage to the speaker.
- User don't have to worry about the problem of the speaker burning out if connect to 100W~200W speaker.Module can connect 12V~24V.The higher the voltage selected, the greater the sound or power that can be output.
- Speaker power cannot exceed 200W, otherwise it will affect the sound quality.
- The input power is insufficient.Please change the adapter power supply with higher voltage level.
- Power supply itself intermittent power-off protection.Please change a match power adapter.
- The power of the power supply is too large so please reduce the power of the input power.
- The power amplifier board is seriously heated resulting in trigger overheat protection.So please increase the radiator.
- Q: The middle BASS potentiometer is used to control the bass. Rotate to the right to enhance the bass. Rotate to the left to attenuate the bass.When the potentiometer is in the middle position, the bass is not enhanced or attenuated.
- The left TREBLE potentiometer is used to control the treble. Rotate to the right to enhance the treble. Rotate to the left to attenuate the treble.When the potentiometer is in the middle position, the treble is not enhanced or attenuated.
- Pay attention to the adjustment of high and low bass: when the treble or bass is adjusted to the right to close to the maximum, if the sound is distorted, it means that the gain of the treble or bass adjustment is too large.The user needs to turn the treble or bass potentiometer to the left to lower the gain or turn the VOLUME potentiometer to the left to reduce the total volume.
