  Lisa KellerSep 22, 2025
  If your Yamaha Subwoofer's power does not turn on automatically when the source begins playing, it could be due to the following reasons: * If INPUT is set to ANALOG, the unit is not operating in linkage with the Pairing Master; turn on the power manually. * Low-frequency input signal may be absent because of settings on the amp; change the amp’s settings. * Because there was no network connection for an extended time, the unit entered eco standby mode; turn on the power manually.

  Ronald KruegerAug 25, 2025
  If the Yamaha Subwoofer suddenly turns off during use, it's likely that the protection circuit has been activated due to a rise in the unit's internal temperature. To resolve this, wait approximately one hour for the unit to cool down. Ensure there is enough space around the unit and that it is not covered by any material. Then, turn the power on again.

Why can't my Yamaha MusicCast SUB 100 Subwoofer find the wireless network?
- S
  Steven BellSep 23, 2025
  If the wireless network cannot be found by your Yamaha Subwoofer, it could be due to the following reasons: * A device that generates electromagnetic radiation (such as a microwave oven or radio equipment) is located nearby. If using the unit with a wireless connection, do not use it near such devices. * Access to the network is being restricted by the firewall settings of the wireless LAN router (access point). Check the firewall settings of the wireless LAN router (access point).

  Jennifer JohnsonSep 3, 2025
  If the Yamaha Subwoofer is outputting noise or if an electronic device nearby is emitting noise, a digital device or a high-frequency device might be located too close to the unit. Try moving the Yamaha Subwoofer and the device farther apart.
