THE MAIN MIXER

EQ section
This is a four-band EQ with parametric midrange controls and high and low frequency shelving bands. The EQ can be
switched between two operating modes, each with slightly different curve characteristics. There is also a filter section
with low pass and high pass filters.
The EQ can be placed before or after Dynamics in the signal path - see “Signal Path section”.
The parameters are as follows:

Description
LPF “ON” button Activates/deactivates the low pass filter. A low pass filter lets low frequencies pass and cuts out the high frequen-
cies.
HPF “ON” button Activates/deactivates the high pass filter. A highpass filter is the opposite of a lowpass filter, cutting out lower fre-
quencies and letting high frequencies pass.
LPF Frequency The Low Pass filter (LPF) removes high frequencies from the signal, making the sound less bright. The LP filter
has 12dB/Octave roll-off curve. Range is 100 Hz - 20 kHz.
HPF Frequency The High Pass filter (HPF) removes low frequencies from the signal, causing a thinner sound. The HP filter slope
has a 18 dB/Octave roll-off. Range is 20 kHz - 4 kHz.
FILTERS TO DYN S/C
button
See “About the Filters To Dynamics Sidechain button”.
EQ “ON” button Activates/deactivates the EQ. (This does not affect the LPF/HPF filters.)
“E” button When the “E” button is activated the EQ will have slightly different curve characteristics.
In normal mode (E button deactivated), the Gain setting will affect the bandwidth (Q) for the HMF and LMF EQ
sections. The higher the gain, the narrower the bandwidth and vice versa. With E mode activated, bandwidth is
constant at all gain settings, which provides more gentle slopes.
HF Gain/Frequency The HF section provides high frequency shelving equalization. Frequencies above the set corner Frequency will be
cut or boosted by the set HF Gain amount.
The HF Gain control can cut or boost the selected frequency range +/- 20dB and the HF Frequency can be set
between 1.5kHz - 22kHz.
