Alto Uber FX [10/48] Troubleshooting

Troubleshooting

If the unit is not charging: Make sure the power cable is properly connected to the power

input and the power outlet.

If the sound is distorted: Try lowering the volume control of your sound source, musical

instrument, or microphone. Also, try to reduce the overall volume of Uber FX using the Master

Volume knob.

If there is too much bass: Try adjusting the tone or EQ control on your sound source to lower

the bass level. This will allow you to play the music louder before clipping (distortion) occurs.

If there is a high-pitched whistling noise when using microphones: This is probably

feedback. Point the microphone away from the speaker.

If you can’t hear the microphone over the music volume: Turn down the music volume

from your source.

If you can't hear your instrument: Check the setting of the Line/Mic switch. If you are using

an instrument with passive pickups, set the switch to the Mic setting.

If you can’t play music from a flash drive: The USB port is only for charging USB devices.

If you cannot connect your audio device to Uber FX via Bluetooth:

• Have your audio device (e.g., smartphone or tablet) and Uber FX as close together as

possible while trying to connect. Make sure both the audio device and Uber FX are

unobstructed by walls, furniture, etc.

• Reset the Bluetooth connection on Uber FX to disconnect Uber FX from any other audio

device and restart the search process. If this does not work right away, power off Uber

FX and then power it back on. See Pairing a Bluetooth Device Using NFC for more

information.

• Reset the Bluetooth connection on your audio device by turning Bluetooth off and back

on. You can find this under the Bluetooth menu in the Settings for your phone or other

audio device.

If this does not work, and you have connected to Uber FX before, find Uber FX in the list

of available or previously connected devices in your audio device's Bluetooth menu, tap

the "gear" or “i” icon located next to it and then select Unpair or Forget. Turn Uber FX

off and back on and try pairing again once it reappears in your available devices list.

Note: If Uber FX has been paired to another audio device recently that is still within

range, you may need to repeat this process with that audio device to fully disconnect.
