8. Solució De Problemes
If you encounter any issues with your Nobsound M10 amplifier, consulteu els següents problemes i solucions habituals:
- Q: Is it normal for the M10 to become warm during operation?
- A: Yes, it is normal. The M10 uses a high-efficiency TPA3255 amplifier chip, which naturally generates heat during use. When powered with a 32V supply, the surface temperature may reach around 113°F (45°C). This does not affect its performance or lifespan.
- Q: Why does the M10 shut down automatically during use?
- A: The M10 requires a power supply with at least 100W output. Auto shut-off usually indicates that your speakers demand more power than the current power supply can provide. Please reduce the volume or use a higher-wattage adaptador de corrent.
- Q: Is the included power adapter sufficient?
- A: The 32V/5A adapter (if included with your purchase) is sufficient for most home speakers. If you purchased the version without a power supply or require higher output for demanding speakers, please use a high-quality adapter with adequate power (e.g., 100W or more).
- Q: How do I switch between AUX, Bluetooth, and USB inputs?
- A: The M10 has an input priority: AUX > Bluetooth > USB.
- AUX takes priority when connected.
- To use Bluetooth, disconnect the AUX cable.
- To use USB, disconnect the AUX cable and pause any active Bluetooth playback.
- Q: Which systems support USB input on the M10?
- A: USB input works only with Windows computers (Windows 7 to 11, no driver needed, plug and play). It does not support phones, Macs, or other OTG devices.
- Q: Why doesn’t the Play/Pause button work in AUX / USB mode?
- A: The Play/Pause function only controls Bluetooth playback. For AUX / USB mode, please control playback directly from your source device.
- Q: Can I replace the NE5532 op-amps?
- A: No, the NE5532 op-amps are surface-mounted and are not user-replaceable.
