DS501 OPERATORS’ MANUAL4

CONTROL DESCRIPTION

L.F. 25Hz - 3KHZ

The Low Frequency filter works by severely attenuating

frequencies below the cut-off frequency selected.

H.F. 250Hz - 30KHz

The High Frequency 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.

Note: Filters only effect the signal triggering the gate. See 'KEY

LISTEN'.

Ext/Int In the Int position, this switch causes the gate to respond to the

dynamics of the signal being processed.

In the Ext position, an external audio signal fed to the key input

is used to control the gate, making it possible to gate one sound

using another, independent signal.

Threshold !72dBFs - Infinity

Sets the level at which the gate opens.

The four led meter, to the left of the control, shows the signal

below threshold.

Attack 10uS - 1 Second

This control determines how quickly the gate opens. The fastest

Attack time ensures that the gate does not clip the leading edge

of extremely fast transients.

Note: See section on using Attack under 'OPERATION'.

Hold 10mS - 2.5 Second

Determines the amount of time the gate is held open after the

signal falls below the Threshold.

Decay 5mS - 4 Second

Determines the rate at which the gate closes, once the signal has

fallen below the Threshold and the Hold time has expired.

Range 0dB - !80dB

Sets the amount of attenuation applied to the signal when the

gate is closed. This enables the gate to remove unwanted signals

entirely, or simply to attenuate signals which are too loud.

Note: Active on both channels, even in stereo linked operation
