The Key Filters
Source Switch
Ext/Linked/Internal
With no LED lit the source comes from the ‘Internal’ signal. In the Ext position the gate
responds to the signal dynamics of another, independent signal as plugged in via the
1/4” jack. This jack works in the same way as the ‘Key Input’ jack of the DS201, DS404
or DS501.
Using the innovative optical infra red triggering mechanism linking can be acheived
regardless of the 500 series rack that you use. With the switch ‘Linked’ the signal
trigger of each linked channel is set by the ‘Key Filters’ section and the Threshold of the
adjacent left channel - if this is also linked this continues until the Master DS101 is
reached. Note that only adjacent channels can be linked. The Attack, Hold, Range and
Decay controls, as well as the Duck and Bypass switches remain indepentent. In this
way the triggers are the same but differing envelopes can be used for each channel.
Using External Keys
An external audio source may be used to control the Gate action, making it possible to
Gate one channel’s sound according to the dynamics of another independent signal.
For example, gating a bass guitar from a kick drum, or where a brass section can be
keyed from the most experienced player; producing a tighter, more aligned sound.
L.F.
22Hz to 3kHz
The Low Frequency control works
by attenuating frequencies below
the cut-off frequency selected.
H.F.
25Hz to 30kHz
The High Frequency control
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 and is the source used to trigger the gate. The optimum use of these
controls is to momentarily operate the channel in Key Listen, and tune-into the loudest
part of the trigger source sound.
