FREQ FREQ
Frequency
0.0218 ···
22.3482 (Fil 1)
44.6960 (Fil 2)
This parameter is used to set the frequency
of the selected filter (in kilohertz).
RESONANCE RES 0 ··· 100.00
This parameter is used to set the amount of
resonance of the selected filter.
FILT 2
(only)
F2 INPUT INPUT
Available on FILTER 2 only, this parameter allows you to select
the input (the audio source) of
FILTER 2:
OFF
FILTER 2
receives no input (but it can
generate tones on its own when in full
resonance).
MIX
When this is selected, the output of PRE
FILTER MIX
is fed into FILTER 2. When MIX is
selected as the input, the A6’s filters
operate in parallel. This means that both
filters are filtering the sound independently
at the same time. Use the level knobs in
POST FILTER MIX to “mix” the levels coming
from both filters.
To filter the A6’s audio by
FILTER 1 only,
simply turn off
FILTER 2 by turning the FILT2
LP
knob fully counter-clockwise.
To filter the A6’s audio by
FILTER 2 only,
simply turn off
FILTER 1 by turning the FILT1
LP
, FILT1 HP and FILT1 BP knobs fully
counter-clockwise.
NOTCH
When selected, FILTER 2 will filter the output
of
FILTER 1’s notch filter(Low Pass and High
Pass, post-fader). The output of
FILTER 1 LOW
PASS
and FILTER 1 HIGH PASS will be
disconnected from feeding the VCA
directly—their knobs feed only Filter 2.
BP
Band Pass
When selected, FILTER 2 will filter the output
of
FILTER 1’s band pass filter.
