MULTI-CHANNEL ANALOG MIXERS WITH ENHANCED FX, USB RECORDING MODES, AND BLUETOOTH®
51
Noise / Hum
•
Are the EQs set to reasonable levels?
•
Are any aux returns maxed out?
•
Are you using unbalanced cables? Swap them out with balanced cables to see if that fixes the problem.
•
Try the same source signal in another channel, set up exactly like the suspect channel.
•
Try disconnecting the cable connected to the input jack. If the noise disappears, it could be a “ground loop,”
rather than a problem with the mixer.
•
Turn the input gains down one-by-one. If the offending noise disappears, it’s either that input or whatever is plugged into it.
If you unplug the whatever-is-plugged-into-it and turn the input gain back up and the noise is gone, it’s from your whatever.
•
Is phantom power required for the microphone?
•
Whenever possible, plug all the audio equipment’s line cords into outlets which share a common ground.
The distance between the outlets and the common ground should be as short as possible.
•
Make sure none of the signal cables are routed near AC cables, power transformers, or other EMI-inducing devices.
•
Is there a light dimmer or other SCR-based device on the same AC circuit as the mixer?
Use an AC line filter or plug it into a different AC circuit.
