Focusrite Green Range, Manual

Setting the Gain
Use the meter and gain control to match the incoming level and gain to the internal
operating level. With an input signal coming into the channel, watch the meter as
you use the gain control to modify the gain, and set the gain control so that the
meter registers between -3 VU and 0 VU. This sets the level above the noise level of
the unit, and leaves room for any sudden increase in performance level (it gives
about 20 dB of usable headroom).
Setting the Phase
When recording a single source using more than one microphone, it is possible for
the signals from the microphones to be out of phase, which affects the quality of the
recording since signals that are out of phase tend to sound “thin”.
For example, when recording a snare drum with two microphones (one on the top of
the snare, the other on the bottom) they will be out of phase. Use the phase switch
to reverse the phase on one of the microphones (but not both) - it normally doesn’t
matter which microphone you reverse. However, if the source is being picked up by
another microphone (for example, by an ambient microphone) then you need to
ensure that you do not put your two close microphones out of phase with the
ambient microphone.
