Frequently Asked Questions
Q: What is the difference between the JQ-D171BT and JQ-D169BT Bluetooth decoder boards?
A: The JQ-D171BT delivers 2×80W of amplifier output and supports a wider voltage range of DC 6V–24V, making it suited for higher-power speaker setups. The JQ-D169BT outputs 2×30W and operates at DC 6V–16V — it features Bluetooth 5.3 and a dancing three-color LED display, making it a great choice for compact or decorative audio builds.
Q: What audio formats does this Bluetooth audio decoder board support?
A: Both the JQ-D171BT and JQ-D169BT support MP3, WMA, WAV, FLAC, and APE lossless audio formats, ensuring high-quality audio playback from USB drives, TF/SD cards, or wirelessly via Bluetooth.
Q: Can this module be used as a standalone amplifier with an external audio source?
A: Yes. Both modules include a LINE IN input, allowing you to connect any external audio source directly — such as a phone, tablet, or audio player — without using Bluetooth or USB storage. The built-in amplifier then drives your connected speakers at full rated power.
Q: What power supply do I need for this decoder board?
A: The JQ-D171BT requires a DC 6V–24V supply with at least 2A of current (DC 12V recommended). The JQ-D169BT requires DC 6V–16V at 2A or more. A stable regulated power supply or suitable battery pack at the correct voltage will work well for both models.
