Product Description
XY-C15H 20Wx2 APP Control Audio Amplifier Bluetooth-Compatible Subwoofer Board Stereo Wireless HiFi Speaker Module Set
Feature:
Audio input supported: Bluetooth-compatible 5.0, AUX,
Audio output supported: active speaker, passive speaker (note: passive speaker and active speaker can only choose one)
Classic looking multifunctional main knob. The main knob uses the rotary encoder used by high-end power amplifier to achieve 360 degrees of stepless tuning; Feel smooth, one button start and stop. Long press switch machine simple and convenient operation
Bluetooth-compatible high-speed and stable connection. Built-in super 5.0 series Bluetooth-compatible chip, effectively reduce the playback lag
Mobile APP control. APP visual operation playback mode supports for Apple/Android (please download for Google Market, search ‘Sinilink’ to download).
The heat sink affixed by special thermal silica gel is used for heat dissipation, and the heat dissipation area is doubled to ensure the full power and high performance operation of the product.

Tips:
1. Audio input mode switching:
This product is powered on in Bluetooth-compatible mode by default when no external audio device is mounted. Follow the backplug device priority principle during playback. For example, if AUX is inserted during Bluetooth-compatible playback, it will be switched to AUX playback immediately. Audio mode can also be switched by APP, which is very convenient. AUX line with shielding layer should be selected as far as possible to reduce noise when AUX is playing. If it is used with desktop computer, AUX output interface behind computer host should be used as far as possible, as AUX output in front of computer may have noise.
2. Power supply selection:
The power supply range of this product is 9-26VDC, compatible with the standard 5.5-2.1/2.5 power adapter plug, recommended to use 12V/24V standard power adapter, current output 2A or more.
1)The power supply size is related to the speaker power, such as the use of 4Ω/15W speaker power supply is less than 12V; Use 8Ω/30W speaker, power supply does not exceed 24V.
2) The power supply voltage should not be higher than 26V, higher than 26V, the circuit board will be burned.
3) If the power amplifier board restarts after the volume is increased during the playback, it is caused by insufficient power supply. Replace the power supply with a larger output current.
3. Speaker selection:
This product can continuously output 15W*2 power amplifier, 10W~100W speakers can be pushed, 8 ohms or 4 ohms speaker is recommended.
If music speakers appear "hiccup" phenomenon, the first consideration is insufficient power supply, use a larger power supply; Second, consider the power amplifier overheat protection, strengthen the heat dissipation or turn down the playback volume. If multiple speakers are used in parallel, the total impedance of the parallel speaker must be controlled above 4 ohm. If the impedance is too small, the power amplifier is easy to enter the overcurrent protection state.
4. Power amplifier board heat dissipation problem:
It is normal for the power amplifier board to generate heat when driving the loudspeaker. If the output power is 20W x 2, you need to install additional heat sink for heat dissipation
Note:
Use 4Ω speaker, power supply cannot exceed 12V; Use 8-ohm horn, power supply cannot exceed 24V
