If your Alto Professional speaker has no sound, start by ensuring the power plug is correctly connected. Next, verify that the function switches are in the correct positions and that the volume knob is turned up. Also, check the mixer's volume. Confirm that all signal lines are working correctly, and try using different signal lines to rule out any issues with the cables.
How to fix Alto Professional Speakers that won't turn on?
If your Alto Professional speaker won't turn on, first ensure the power cable is securely connected to both the speaker and the power outlet. Then, check that the power switch is in the 'ON' position. Also, verify that the wiring is complete and correct, and that all function switches are set to the appropriate positions.
What to do if my Alto Professional BLACK 12 have audio distortion?
If you're experiencing audio distortion with your Alto Professional speakers, begin by checking that the DSP Mode switch is in the correct position. Ensure that the connected sound sources are outputting sound properly, and try testing with different sound sources. Also, make sure the volume knob is adjusted to the proper level.
Why is the sound so low on my Alto Professional Speakers?
If your Alto Professional speaker has low sound, first check if the connected signal lines work properly and try different signal lines. Then, check if the connected sound sources work properly and try different sound sources. Also, verify the volume knob is adjusted correctly and that the DSP mode is properly set.
How to fix Bluetooth disconnection on Alto Professional Speakers?
If your Alto Professional speaker's Bluetooth keeps disconnecting, first check that the Bluetooth switch is turned on and the Bluetooth LED is in search mode. Next, ensure the Bluetooth switch on your Apple device is also turned on and in search mode. If the speaker is found, verify that the device pairs successfully.
What to do if the Alto Professional BLACK 12 APP is not responding?
If the app is not responding with your Alto Professional speaker, first ensure that the Bluetooth software is successfully installed on your Apple device and that the device is successfully paired with the speaker. If they are paired, try turning off, restarting, and reconnecting the speaker. If the issue persists, turn off, restart, and reconnect the software. If none of these steps work, turn off and restart your Apple device, then reconnect and pair it again.
How to update my Alto Professional BLACK 12 Speakers if it is not updating?
If your Alto Professional speaker cannot be updated, ensure that the Bluetooth function is turned on and that the Bluetooth connection is successfully established. Also, verify that the update software you are using is the correct version.
