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.
