How do I connect a digi 003 to mackie d8b?

Don't know your setup but have you checked out any possible Hum loops? Have you updated any firmware updates? Is your mains input clean (no spikes or very short drop outs of voltage)? Are you near any possible RFI, e.g. Taxi's or CBr's? The list goes on so check out the Mackie forum on the web for more. Good Luck...

SOURCE: my mackie d8b just stop picking up any input

Also check your phantom power - if your mics need phantom power and it's not there...

I have one of these, you may have a problem with a capacitor, they tend to go every 5 years or so. its a back to base job, but you probably dont need to send your cpu, just the mixer unit.

This is vague,,, there are so many outputs, knobs, LED's that I suspect you have not tried the right combination. I have no idea what your signal sources are... mics... tape... etc.

To start, turn the trim control of one channel that you have a signal source connected. Set all the EQ controls and the pan CONTROLS TO 12 O'CLOCK.

Check that you can trigger the clip light with high level of input. Press the solo button for that channel and using a set of headphones listen for any signal... turn the headphone level up and the slider for that channel...

First do your basic checks,,, try EACH mute button and see the LED light... try each solo button and see that each will light AND also that ANY solo light will cause the RUDE solo light to come on...

Just use balanced audio interconnect cables (XLR or TRS) between the mixer and the M-Audio interface.
