Have you tried another source into the same input on the mixer and does this also come through quiet? Have you checked the gain for the channel(s) you are using? Have you tried a different wire for the connection as well as different source? Is it on all channels? have you tried a different amp?
Place your mixer in a location that will allow you to hear the sound coming from the speakers clearly. The best placement is opposite the speakers, centered between the left and right pair. Connect the power supply to your mixer.

Connect the female end of an XLR cable to a microphone. Run the other end of the cable to your mixing board. Plug the male end into the "Mic" port of an open channel. These channels provide the preamps that will shape the sound characteristics of the microphone signal, processing them for output. Repeat the process for each microphone in your rig
3
Connect one end of a balanced 1/4-inch cable to the left channel jack labeled "L" found on the "Main Out" panel. Connect another cable to the right channel jack with the "R" label. Connect the opposite end of each cable to the matching left and right inputs on you amplifier.
4
Power on your mixer and amplifier. Test each microphone connected to the mixer for output.
5
Adjust the volume of each microphone channel to create a balanced mix. Use the "EQ" knobs to shape the tone and cut out frequencies that are causing squeal and feedback.
Get yourself anti-static spray and spray over the connector before inserting into the jack, most times its dust or static buildup which causes that buzzing sound and in other times replace your mic
Is the sound a low frequency buzz or high frequency hiss? With all the input level controls at the minimum position and the output level controls at the maximum is the sound audible?
Waiting clarification, don't hesitate to post.

Either through your computer's soundcard (1/8" mic input) or you'll have to get an interface such a an M-Audio FastTrack. There has to be something that converts the analog sound from the mixer to digital info that you're computer can utilize.
You will need an oscilloscope and a good grounding in electronic servicing to attempt a repair.
But, check the signal routing. Refer to the user manual.
It sounds like you're experiencing a couple of issues with your Behringer Xenyx 1204FX mixer. Let's address each of these problems separately:
DSP Display Not Illuminating: The fact that the DSP display works when you press down and turn the knob suggests that the issue might be related to the display itself or its connection. Here are a few steps you can take to troubleshoot the problem:
Check Power Source: Ensure that the mixer is receiving proper power and is turned on. Sometimes display issues can be caused by power-related problems.
Connection: Make sure the ribbon cable or connector that connects the display to the circuit board is properly seated. A loose connection could be causing the display to not illuminate.
Faulty Display: If none of the above steps work, there might be a problem with the display itself. You may need to contact Behringer support or a professional technician to get the display repaired or replaced.
AUX 1 Send Not Working: If the AUX 1 send is not working as expected, there could be several reasons for this:
Routing Settings: Make sure that the AUX 1 send is properly routed to the desired destination. Check the routing options on the mixer to ensure that the signal is being sent to the correct output or destination.
Level Controls: Verify that the level controls for AUX 1 are set correctly. Make sure that the AUX 1 knob for the specific channel you're working with is turned up.
Effects/Processing: If you're trying to send a signal with effects applied, check if the effects are set up correctly. Sometimes, an incorrect effect or routing setting can affect the AUX send.
Cable and Connections: Ensure that the cables connecting the AUX 1 send to external devices (such as monitors or effects units) are functioning properly and securely connected.
AUX Master Level: Confirm that the AUX 1 master level (usually located on the main output section of the mixer) is turned up to an appropriate level.
If you've gone through these troubleshooting steps and the issues still persist, it might be a good idea to consult the user manual for your Behringer Xenyx 1204FX mixer for further guidance. If the problems continue, you may need to reach out to Behringer support or consider seeking assistance from a professional audio technician or repair service.
Hello Geoff, try using an external processor and check that it works well, if so, the problem is that you have the Jack connectors of Effect sending and those of Return of Effects, dirty
Apply a couple of drops of oil, type WD40, to a Plug connector and insert and remove them repeatedly in each connector Jack for sending and returning effects
I hope you can solve the problem, comment the results
Greetings Franco Dosil
Hola Geoff, prueba usando un procesador externo y comprueba que funcione bien, si es asi, el problema es que tienes los conectores Jack de envio de Efecto y los de Retorno de Efectos, sucios
Aplicale en un conector Plug un par de gotas de aceite, tipo WD40 y entralos y sacalos repetidamente en cada conector Jack de envio y retorno de efectos
Espero puedas solucionar el problema, comenta los resultados
Saludos Franco Dosil

Check all the wiring connections on the speaker. Check the plug in points for the cables are not loose in the body of the speaker or the connector plugs themselves are not loose in the actual plug sockets.
Next you will need to get inside the speaker body to check the connections and soldered joints. Take a good look at the back of the cable plug sockets and to the back of the actual speaker cone connections. Check each wire at Both ends for damage. No sound at all suggests the issue might be at the 'Input' where the cable plugs into the back of the speaker body.
If the right input on your Behringer Ultracoustic ACX1800 CD is not working, it could be due to a number of reasons, including:
A faulty cable or connection: The problem could be as simple as a loose or damaged cable. Try swapping out the cable with a known working cable or check the connection to ensure that it is secure.
A blown fuse: The ACX1800 CD has a built-in fuse that protects the internal components from power surges or other electrical issues. Check the fuse to make sure it is not blown and replace it if necessary.
A damaged preamp or amplifier circuit: If the problem is not with the cable or fuse, it could be due to a damaged preamp or amplifier circuit. This can be caused by a number of factors, such as overheating, power surges, or other electrical issues. In this case, you may need to take the ACX1800 CD to a professional repair technician to diagnose and fix the problem.
A faulty right channel input jack: It is also possible that the right channel input jack itself is faulty. This can be caused by wear and tear over time or physical damage. In this case, you may need to replace the input jack or have it repaired by a professional technician.
