Warranty Service

If you think your Mackie product has a problem, please check out the following troubleshooting tips and do your best to confirm the problem. Visit the Support section of our website (www.mackie.com/support) where you will find lots of useful information such as FAQs, documentation, and user forums. You may find the answer to the problem without having to send your Mackie product away.

Troubleshooting

Bad Channel

•Is the MUTE/ALT 3–4 switch in the correct position?

•Is the fader turned up?

•Try unplugging any INSERT devices (Channels 1–6 only).

•Try the same source signal in another channel, set up exactly like the suspect channel.

Bad Output

•Is the associated level knob (if any) turned up?

•If it’s one of the MAIN OUTS, try unplugging all the others. For example, if it’s the 1⁄4" Left Main out, unplug the RCA and XLR Left outputs. If the problem goes away, its not the mixer.

•If it’s a stereo pair, try switching them around. For example, if a left output is presumed dead, switch the left and right cords, at the mixer end. If the problem switches sides, it’s not the mixer.
