4 Controls
4.1 Mid Lift
The amount of mid lift is continuously variable between 0
and 21 dB. The actual amount of gain is dependant on the
Q setting, so at a narrow Q, 21dB can be added at the
centre frequency but at a wide Q, this will drop to around
16dB.
f (kHz)
This control will select the centre frequency of the mid
boost circuit.
Q
This control sets the width of the frequency band being
boosted. ‘H’i is a very narrow band of frequencies either
side of the centre frequency, ‘Lo’ is a wide band of
frequencies.
4.2 Mid Cut)
The amount of mid cut is continuously variable between 0
and -17 dB.
f(kHz)
This control will select the centre frequency of the mid cut
circuit.

‘Cut’ brings a lo pass filter in which reaches -6 dB at either
15, 11 or 6 kHz.
‘Lift’ brings a shelving Eq in, which reaches its peak of 6 dB
at either 15,12 or 10 kHz.
