I cant get my mackie 2404 VLZ3 to record any audio? I have the board setup to record from the master but no audio comes into my computer. What to do next?

Probably the power inside the mixer needs to be looked at.

Sub outs needs an active speaker.

An active speaker have a built in amplifier and preamplifier.

For a passive speaker it needs an amplifier.

Upon opening the mixer, you might find that the preamp boards are

similar , use the running board as a guide in troubleshooting .

On most are the XLR inputs with phantom supply.

Without more information of your speakers and amps we can't really help you. The Mackie board puts out line-level signals and that should drive any connected amp or powered speaker to the full capability. Make sure you are using BALANCED interconnect lines either XLR or TRS cables. Use of TS unbalanced cables costs you 6 DB and also noise pickup. Make sure ALL your gear, amps, speakers etc are powered from a SINGLE receptacle or power conditioning module. Normally you will use the AUX outputs of the mixer by way of TRS cables or balanced lines in a snake to power amplifiers onstage which then connect to the stage monitors. If you have powered monitors the returns of the aux to the stage go to the powered monitors. A heavy duty extension cord brings power back from thee stage power to the mixer.

You would connect at Aux outs of Mackie to inputs of Peavey

Possibly you are using the audio from the subs or the Aux which are NOT controlled by the slide faders?

Sometimes users turn up the stage monitors to the point they can't control enough with the mains.

Make sure your system passes the audio to the amps from the XLR plugs for the mains on the back AND you use BALANCED lines to do so.

you need a recording device to do it, a recording software and most of all an

interface.

Using two balanced lines either TRS or XLR depending on what is on your M audiointerface, connect the L and R main outputs of the mixer to the L and R inputs of the M Audio. You will need recording software on your computer.
