“Setting up a good vocal – you can’t go wrong with an SM58 here. Sing straight into it (it should be touching your top lip!); set the desk gain according to your listening level not what the LED meters say; pop the filter in and even wind out the low-EQ as well. That should get you started…”
Now that comment got a request from Tim Brown asking Tim Horton to explain more about the LED issue. Here is Tim’s response:
Yes, this is something that I am asked about a lot…
The idea is that all too often we are setting our gain levels by the LEDs on the board; we spin the gain in until the lights tell us it’s the correct level.
But how do we know this is the right volume in the system?
What about doing it this way:
N.B. This should be done 1 channel at a time, not whilst everyone else is playing.
Set gain to minimum
Push fader to -5dB (minus 5)
Pad if necessary
Add gain until it is at an appropriate volume level
Open eyes and check that there are no red lights on the meter
EQ to taste
Adjust gain if necessary (EQ can compromise gain setting)
Bring fader down to minimum
Set monitor level as appropriate
Fader back to -5dB
Everyone happy? Move to next channel
Some further thoughts; if you are doing it like this and adjusting the gain according to the volume level you require then you are engineering sound, rather than watching LED meters. The meters are helpful as a reference, but shouldn’t be used as a crutch.
The assumption is made that your system is capable of the sound levels you require of it! Of course, if the system cannot give you the volume you need then you will be hitting the red lights.
In a similar way, we should not be asking small speakers to give us a huge bass sound. If you haven’t got a sub then don’t try to get that punchy kick drum / bass guitar sound; the speakers simply won’t be able to keep up.
Ok, so you don’t have to shut your eyes, but if you are prone to watching the meter for level setting then why not?
It will take practise to get this right, especially once you set monitor levels.
Speaking of monitor levels; your front of house sound should be 10dB louder than the monitors / stage noise. If it’s not then the muffled monitor sounds will overpower your detailed FOH mix.
Once you have set the monitor levels, you should never adjust the gain as it affects the entire channel and all associated feeds (auxes for monitors, recording, effects; matrices, etc).
By setting the fader to -5dB we are giving ourselves an extra 15dB of level in the FOH which should be plenty of headroom in the mix.
