If you are using Behringer P16 personal mixers with the X32, chances are, you have run into volume problems. A majority of people I come in contact with who are using the P16 personal mixers have complained that they are not loud enough.
Good news is, the P16s have plenty of volume control. It is probably just a setting or two that is causing the problem. So, let's go over the four things you need to check.
Gain is the most important knob on your mixer. If it is not set properly, it messes with everything else (including the P16s). So, the first step to solving P16 volume problems is to make sure the gain is set correctly on every channel.
Here’s a post to help you out: How to Set the Gain on Your Mixer
On the Behringer X32, the ‘tap’ setting lets you decide at what point in the signal chain to send that specific channel to the P16. In other words, you can send a channel with or without EQ, with or without compression, etc.
On the X32, navigate to the 'Routing -> p16 out (or ultranet)' tab. Then, check every channel to make sure 'Tap’ is not set to ‘Post Fader’ (unless you specifically want it to be). Basically, if ‘tap’ is set to ‘Post Fader’, when the sound tech adjusts the volume of a channel in the main mix, it will adjust the volume of that channel in the P16s as well.
On the P16 personal mixer, there is a button labeled ‘Main’. Press this button and then turn the volume all the way up. As you may have guessed, this is a control for the overall volume of the P16. But, so is the ‘Level’ knob at the top right of the P16.
I have found that it is best to turn the ‘Main’ volume all the way up and then use the output ‘Level’ knob to adjust the overall volume. If the ‘Main’ volume is not all the way up, you may find the output ‘Level’ knob all the way up but the mix still not being loud enough.
If everything is set correctly, the output ‘Level’ knob should be set around 2 o’clock and the mix be plenty loud enough.
The limiter on the P16 personal mixer is there to protect your ears. But, if you have it set too low, it will ‘limit’ the volume of your mix.
Basically, you want the limiter to protect your ears from any loud noises that sneak through, like feedback from a vocal mic.
The limiter knob is a little counter-intuitive. If you have it turned down, it is going to limit more, but if you have it turned up, it is going to limit less.
I have found that having the limiter all the way up, which means it is limiting less, works the best. You’d think it wouldn’t limit at all in the case, but it actually does continue to limit, but only the loudest moments.
Keep an eye on the red light around the limiter, which lets you know when the limiter is activated. Basically, you just want it to flash occasionally during the loud moments. So, if it never comes on, you may need to dial it back a bit to make sure your ears are protected.
When the four things above are all taken care of, you should find that there is plenty of volume headroom when using the P16 personal mixers.
