Q&A/ Troubleshooting

1. Get noise when playing music?

• Try to use other Bluetooth devices. Weak or unstable Bluetooth signal will cause this problem, try to close your device to the BT30D.
• Try another RCA cable and make sure the audio cable is connected correctly.
• Please unplug the RCA cable from the amplifier, and then turn it on to have a try.
• Please change the audio cable and audio source to have a try.
• Did you set the “treble” volume to the top? please volume down the “Treble” volume.
• The gain of BT30D is larger than other model, you can volume down the “Treble” sound. Some speakers are very sensitive so that the white noise will be obvious, it’s normal that BT30D has some noise when you turn up the “Treble” volume.
• Make sure that all the cables are completely pushed into the device, incompletely connection will cause this issue.
• Please keep this device away from other electronic devices.

2. All cables are connected, but there is no audio output?

• Please check the indicator light on the front panel of the amplifier and the power supply are on.
• If the indicator light is on, please check if the volume knob is at the minimum state, if it is, please turn up the volume.
• Make sure that BT30D is in the play mode you want.

Note:

Bluetooth input mode (The input mode indicator light will turn blue.) RCA input mode (The input mode indicator light will turn red.) Once
Bluetooth is connected, the RCA input will be interrupted.

– Please check if the audio source is paused.
– Please try to change the sound source, cables and speakers/subwoofer.

– Make sure that BT30D is powered on and the LED light on the power adapter is blue.
– Make sure that BT30D is not paired with other devices.
– Make sure that the distance between your device and BT30D is not too long, close your device to BT30D to have a try.
– Make sure there are no obstacles between your device and BT30D, obstacles will affect the Bluetooth operation distance.
– Please try to change another Bluetooth audio source to test.
– Please replug the power supply, move the amplifier to another room and test it again.
– Restart the BT30D and then try to connect again, try to use another brand of mobile phone..

4. One channel does not work?

• Please test whether the Bluetooth and RCA input have the same problem first.
• If the two modes have the same problem, swap the speaker cables of the left and right channels, or change another speaker, and then test whether this channel still does not work;
• If only RCA or Bluetooth mode does not work, change the audio source, change the RCA cable and test again, and make sure that all the cables are completely pushed into the device.

5. Can I connect a turntable to it?

• If your turntable has a built-in phono preamp, you can directly connect the BT30D to your turntable with RCA cable.
• If your turntable does not have a built-in phono preamp, you need to add a phono preamp to the turntable and BT30D, similar to our BOX X2.

6. Can’t power on?

•  Make sure that the LED light on the power adapter ison.
• If it does not light up: Unplug the power adapter from the BT30D, plug the power adapter directly into the AC power source, and see if the LED will light up. If it still does not light up, it may be a problem with the power adapter. Please contact us to replace the power adapter.
• You can use the DC12-24V power adapter of the camera or router to connect the BT30D to test whether the BT30D can be turned on.

7. Sound quality is not good?

one speaker? Or just use it as a subwoofer preamp?

• Yes, you can do it. You don’t need to connect all the outputs.
