TYPE:
The 5 types of EQ that can be used are: parametric (PEQ), low shelf (LO-SHF), high shelf
(HI-SHF), 1
st
degree all-pass (AP-1), and 2
nd
degree all-pass (AP-2).
FREQ:
The EQ center frequency ranges from 20Hz to 30kHz in either 1Hz steps or 1/36 octave
steps. The frequency steps can be selected in the
System Menu
.
Please refer to page 21
for more details.
BW:
The EQ bandwidth ranges from 0.02 to 3.61 octaves in steps of 0.01 octave.
The
equivalent Q value is automatically shown besides the octave value.
For 1
st
degree
all-pass (AP-1) filter, the bandwidth will sets the phase shift at the centre frequency.
This
phase shift is gradually changed from 180 degrees above the centre frequency to the
specified value.
LEVEL:
The EQ level (or gain) ranges from -30.00dB to +15.00dB in 0.25dB steps.
Input Graphic Equalizer
GEQ#:
The graphic equalizer has 31 bands of equalization from 20Hz to 20kHz. This control
selects one of the 31 available bands.
The frequency corresponding to each band is also
shown.
LEVEL:
The GEQ level (or gain) ranges from -30.00dB to +15.00dB in 0.25dB steps.
BYPASS:
This control will un-bypass (Off) or bypass (On) the entire GEQ for this channel.
Input/Output Crossover
TYPL:
The 3 available filter types for the low frequency crossover point (high pass) are:
Butterworth, Linkwitz Ri ley or B essel.
FRQL:
The f ilter c ut-off frequency for the low frequency crossover point (high pass) ranges from 20
to 30kHz in either 1Hz steps or 1/36 octave steps. The frequency steps can be selected in
the
System Menu
.
Please refer to page 21 for more details.
SLPL:
The filter slope for low frequency crossover point (high pass) ranges from 6 to 48dB/octave.
If the selected filter type is Linkwitz Riley, the available slopes are 12, 24, 36 or 48
dB/o ctave only.
