(7) Bass Control
The Bass Control is set at 80Hz and allows you to either add or remove
the low frequency content of the signal by 15dB.
Rotating the control clockwise will ’boost’ the signal, rotating the control
anticlockwise will ‘cut’ the signal.
This control is useful for adding more ‘thump’ to low frequency signals
such as bass guitars and kick drums but can also be used to remove
unwanted rumble or boominess from signals such as vocal or instrument
microphones.
(8) Mid Control
The Mid Control is set at 600Hz and allows you to either add or remove
the high frequency content of the signal by 15dB.
Rotating the control clockwise will ‘boost’ the signal, rotating the control
anticlockwise will ‘cut’ the signal.
This control is useful for adding ‘body’ to drums, bass guitars or
percussion but can also be used to remove ‘boxy’ resonant frequencies
from acoustic guitars and other signals.
(9) Treble Control
The Treble Control is set at 12kHz and allows you to either add or remove
the high frequency content of the signal by 15dB.
Rotating the control clockwise will ‘boost’ the signal, rotating the control
anticlockwise will ‘cut’ the signal.
This control is useful for adding ‘crispness’ or ‘sizzle’ to signals with a lot
of high frequency content such as guitars and cymbals but can also be
used to remove unwanted sibilance from signals such as vocals.
