CONTROL DESCRIPTION
Both channels of the DS301 are identical and may be used completely
independently or linked for stereo operation. Only one channel is described
below, with any link peculiarities shown where applicable.
KEY SOURCE
There are three possible triggering sources for the DS301, External, Internal or
MIDI. Selection is accomplished via the three-way toggle switch above the Key
Source filter controls. For conventional use where the audio input itself is used
to trigger the expander/gate, INT should be selected. Alternatively, an external
trigger source may be used by feeding it to the 'return' tip of the Side-Chain jack
on the rear panel, in this case, EXT should be selected. The third option is MIDI
where the unit is triggered from a MIDI source, (refer to MIDI section of this
manual).
Note: If no jack plug is inserted into the side-chain / key-input socket on the rear
panel then the INT or EXT switch positions will both route the audio input through
the filter section.
FILTER
L.F.: The Low Frequency filter provides a slope of 12dB per octave and is
variable from 25Hz to 10 kHz and works by severely attenuating
frequencies below the cut-off frequency selected.
H.F.: High Frequency filter provides a 12dB per octave slope and is variable
from 200Hz to 35kHz, this filter attenuates frequencies above the selected
cut-off value. In other words, when both filters are set, it is the range
between the two settings that is allowed to pass.
IN/ :
Allows the filters to be switched out of circuit when not required.
OUT
The fastest Attack time of the DS301 is attainable when the filters are
switched out, due to the fact that any filter circuit has a slight inherent
delay.
TEST
Depressing the test button causes the gate to respond as though it has been
triggered from a legitimate source. This is useful in setting up the envelope
parameters, particularly in external mode where trigger source input might not
always be available, and also for checking the performance of any MIDI
equipment that you wish to trigger from the expander/gate. Test is also used
when programming the MIDI parameters and this is fully explained in the MIDI
section of this manual.
