Firewire inputs do not work

It sounds like you're experiencing a couple of issues with your Behringer Xenyx 1204FX mixer. Let's address each of these problems separately:

1. 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.
2. 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.

If you are experiencing an issue where the QSC RMX 1450 amplifier is not giving any sound when connected to the main output of your Mackie 16 OK mixer, but works when connected to the aux send, here are some possible causes and solutions:

1. Check the main output level on the Mackie mixer. If the level is too low or muted, this can cause the amplifier to not produce any sound. Increase the main output level on the mixer and check if the amplifier produces sound.
2. Check the cables connecting the mixer to the amplifier. If the cables are damaged or not connected properly, this can cause the amplifier to not produce any sound. Ensure that the cables are connected securely and are not damaged or broken.
3. Check the amplifier settings. Ensure that the amplifier is set to the correct input source and that the input gain level is set correctly. You may also want to check if there are any protection modes or limiters enabled on the amplifier.
4. Check the speaker connections. If the speakers are not connected properly or are damaged, this can cause the amplifier to not produce any sound. Ensure that the speakers are connected correctly and are not damaged.
5. If none of the above steps work, there may be an issue with the mixer or the amplifier. You may need to contact a qualified technician to further diagnose and repair the problem.

Thats all. In Ableton,the setting MIDI input must be set to USB MIDI.

Skype allows only one audio input at the time. You can set up the input device in the skype menu.
Try connecting all microphones to the Mackie and then connect the output from it to the line in or microphone input on the PC, then choose the input you connected it to in skype.

The internal audio systems in the PC's are inadequate for high quality work. You should get an external audio system that attaches via firewire or USB to your MAC. Then use balanced cables from the mixer to this audio interface. There are MANY different audio interfaces... Search the music equipment suppliers in the "recording" section of their catalog...
