 Gain
Structure - 4 - Setting the gain-2 |
Step 1
We will use a simple system comprising a microphone connected
to a mixer, which feeds an amplifier running a pair of speakers.
Connect the mic to the mixer, the mixer to the amp and the amp
to the speakers. Have all the volume controls/faders turned right
down. Locate the 'gain' control on the input channel on the mixer
that the mic is connected to (Fig 1). |

On most mixers, there will be a button marked
'PFL' (standing for Pre Fade Listen) on each input channel. Press
this to on - this routes the input signal from this channel to
the headphone and led meters (See Fig 2). It takes the signal
before the fader (hence Pre Fade Listen) so the fader
position has no effect. You are now ready to adjust the mic input
gain. |
