Gains and mixer settings
|

How do you guys calibrate/configure your mixer for recording and for playing live? Is there a difference?
When I'm recording at home I set the gains to the lowest level and use my amp to raise the volume to the desired level. I figured this would (close to) eliminate distortion which occurs when gains are too high. Am I doing it right in theory? |

no
Need a decent signal/noise ratio
Best way is via unity gain, which is finding the optimum gain settings at every stage of the signal path.
Low gains and high output is just adding a shiedload of noise into your signal |

care to explain, Freak? I would like to know as well, but more importantly, I don't understand the terminology your using, as seeing that it would be helpful for me as well, not to mention other TAs who don't understand what your saying.
Thanks |

ooh didnt realise i could do that now
sorted
:D
Yes you have it
The amp will amplify the entire signal and noise combined
If only a small percentage of that signal is music then after amplification its even worse.
I would explain it better- but i have one f*cker of a headache, so i wont |

All volumes/gains on all your throughput mixing/amplifying devices should be at unity (0db).
Here are two diagrams, the first one is wrong, the second one is correct. EX-1 and EX-2 are just some random devices (such as an effects processor or a sound board). The dashes represent the level in volume/gain:
Wrong volume/gain:
Mixer ====
Amp. =============
Ex-1. ==========
Ex-2. ============
Correct volume/gain:
Mixer ========
Amp. ========
Ex-1. ========
Ex-2. ======== |

Brilliant post! |

I sorta get the idea now with the unity business..all set at 0. therefore there should be minimum noise.
thanks guys !! |
