Common questions about manuals, registration, and support for this brand.
Check the model number printed on the amplifier board or packaging, such as YS-MT21 or YS-TB21H, and select the matching manual. Connections and specifications vary by model.
Follow the model-specific voltage and current requirements, confirm power polarity, and check speaker impedance and wiring. Disconnect power before changing connections and keep the board ventilated.
The YS-MT21 instructions state that Bluetooth takes priority over AUX. A successful Bluetooth connection automatically switches the board to Bluetooth mode, and automatic reconnection is supported.
No verified Sienwiny warranty or registration page is available in the supplied information. Ask your seller for the terms applicable to your purchase and keep your order details.
Check the power supply, polarity, speaker connections, selected input and volume settings against your model's manual. Power off before inspecting wiring, and check for loose connections or short circuits.
