How To Use Equalisation - Focusrite Green Range Manual

Use equalisation to:
• Remove unwanted noise, such as rumble, bass lift and hum (by using the Low filter).
• Reduce hiss (by using the High filter).
• Replace missing bass or treble (by using the Low or High Eq).
• Reduce excessive bass or treble (by using the Low or High Eq).
• Boost room ambience (by using the High Eq).
• Improve tone quality (by using all the controls).
• Help a track stand out in the mix (by using the Low Mid and High Mid Eq).
• Reduce noise and leakage (by using the Low and High filters). Note that you can
also use gating or expansion to do this.
• Boost lows and highs when recording loud bands (by using the Low and High Eq).

How to use Equalisation

1. If recording using a microphone, ensure that the microphone placement is correct.
Listen to the sound from the microphones with no equalisation applied, and
modify the microphone placement until you get the sound you want.
2. Set the operating level.
3. Consider what you don't want (for example, you don't want too much bass on an
analogue tape machine). This varies with the recording format and varies with the
input signal. If necessary, use the low and high filters to remove parts of the signal.
4. Listen to the ambience and room sound that comes back off tape, and check that
it has the frequency response that you are looking for (for example, the room may
be a bit dull in the top end, or there may be too much bass). If the frequency
response is not correct, use the Low and High Eq to correct it.
5. Create a sound and bring out the character of the instruments by using the Low
Mid and High Mid Eq. The section on Bringing an Instrument Forward in the Mix
has a table showing important frequencies for different instruments.
6. Set the final output level using the output fader.
