Talking about common problems and solutions is one thing, but in this article I’m also exploring the over-arching reason why most of these occur and what you can do to avoid them.

The 5 Common Audio Problems / Solutions

1. Partial plugging: I’ve even done this one back in my guitar days.  It’s what happens when the guitarist doesn’t plug their cable completely into their guitar. 

When I don’t get a signal during a line check, this is the first thing I ask them to check.

2. No monitor volume:  You know they are plugged in. 

A signal is being sent to them, but nothing is coming out.  Solution…turn the monitor on (we’re obviously talking about active monitors here). 

It’s so easy to overlook.  Also, if that’s not the problem, I check the controls on the monitor itself.  Sometimes they get messed with too.

3. Bad cables that appear functional: A cable tester can show a cable as good but when it’s plugged into a piece of equipment and the plug is jiggled, static is heard in the system. 

I’ve had this happen even when I jiggled the plug in the cable tester.  The solution is simple - replace the cable and fix the old one or replace it.  Unfortunately it’s not 100% reliable so don’t keep it in service. The only way to prevent this problem is regularly testing of cables.

4. No audio passing through a channel:  The best practice for resolving this is to follow the signal flow. In doing this, it’s easy to overlook the sub-groups, VCA’s, etc. 

For example, a channel that’s assigned to a subgroup but the volume for the subgroup isn’t up.  I find that by resetting the board before I start, I start from the same settings each time and avoid this error.

5. No audio when using a condenser microphone:  You probably already know that condensers required phantom power. It’s just too easy to overlook that because…most “got-ya” problems occur when you vary from your standard routine.  Plus, if you’re using an unfamiliar mixer, sometimes the phantom switch is in a new location.

Thanks for taking the time to discuss and share this with us, I for one feel strongly about it and really enjoyed learning more about this topic. I can see that you possess a degree of expertise on this subject, I would very a lot like to hear much more from you on this matter

One I run into continuously is when a guitar player wraps up practice and then hits the tuning switch (which mutes the guitar). No signal, take it out of tuning mode.

Another one is equipment thhat has it's own volume control, like a computer or acoustic guitar. I try to remind them to keep their own volume at 50% and I'll control it from the board.

tried and true - when I do my own setup and when I teach my helpers, I always say "if something can go wrong, it probably will and at the worst possible time, so anticipate it." Anticipate that someone WILL step on a cable and create partial plug-in, or break the last copper strand in a connector. So, make sure you tie cables off at the amp or monitor, etc., with enough slack to save your Got-cha. If someone does step on it, it will pull at the tie-off rather than the connector. Have spare cables - mic, instrument, power, cat5, DC adapter - at FOH or side stage, or preferably Monitor mix (if you have one) at the ready, not just in the A/V room or backstage in a trunk. If you're a portable church or do roving live, you can never have too many spares. My personal proverb is: it's better to have and not need, than to need and not have.

My first rule of tech is "Always make sure it is plugged in." I repeat it every time I fail to follow it but to others when I happily fix the issue by plugging in power, xlr, cat5, ... I have done #4 for the FOH slides for 5-6 years now and may take it even farther to be the subs and other settings. It would have saved issues. Thank you for confirming what I have practiced and shown ways to improve on it.

Hi Chris,

Always remember the batteries ,9V's in pedals , wireless , active Basses , Acoustic Guitars .

All have got me in the past ,although at sound check.

And don't forget the extra piece of 2-pin a/c powered gear plugged in to stage power at the last minute by someone , introducing that fun 60 cycle hum.

Keep your batteries fresh & your a/c grounded.
