Note: If the DS301 is set to Expander mode and a long attack time is set, then

operating Test will only cause a slight change in level, just as an audio trigger

would under the same conditions. If the DS301 is set for linked stereo operation,

then the left hand Test button will trigger both channels and the right hand

channel Test button will be inoperative as an audio trigger.

ENVELOPE

FUNCTION:

The DS301 operates in either Gate or Expander mode and switching from gate

to expander by pressing the EXPAND button, a status LED lights to show Expand

mode is selected.

Note: The Retrig/Ratio control changes function according to whether gate or

expander is selected;

Expander mode, it controls the expansion ratio.

Gate mode, it functions as a retrigger delay time control.

The other control that affects the characteristics of the DS301 is the Function

select switch; in Gate mode, it allows the user to select between Gating and

Ducking, whereas in Expander mode, the choice is between Expansion and

Limiting. Selecting Ducking allows the level of the signal being processed via the

main input to have its gain controlled by an external signal fed in at the side-chain

input. In Limit mode, the DS301 functions as a basic compressor/limiter.

THRESH:

This control sets the level above which the gate or expander will start to open at

a rate determined by the Attack control. Once open, the gate or expander will

remain open until the signal falls back below the threshold, after which

attenuation will take place at a rate set by the Hold and Release time controls.

The only condition under which the gate will refuse to open when these conditions

have been met is if the Retrigger control is set to such a high value that the

system has not been given time to reset since the last triggering event. The

Threshold is continuously variable between -70dB and infinity.

ATTACK:

Sets the rate at which the expander/gate opens once the input signal has

exceeded the Threshold set by the user. This is variable from a very fast 5uS to

100mS. One feature implemented in the DS301 is that, in Gate mode, the attack

cycle is allowed to complete once triggered, even if the triggering sound is of

short duration. The attack starts from the dB level set on the Range control.
