V-Dyn by Labo ★ K effects

The dynamics unit is set out with the Gate/Expander on the left had side of the module
and the Limiter/Compressor on the right.

The gate /Expander controls are:

Key

Pressing this Button provides a dedicated patch input to the gate only; enabling the gate to be
triggered by an external signal.
The compressor operation is not affected.


INV

This button inverts the external trigger control so that the gate closes when a signal of
the required level is present. This can be used as a « Ducker » or for mutein severe breakthrough frm another source.

HYST

Hysteresis is the difference in dB between the gate mute level (set by the threshold control) and its unmute level.
Varying hysteresis allows more precise triggering of the wanted signal whilst still allowing the correct amount of signal
tail through. (10dB of hysteresis is usually a good starting value for setting the gate). The fully anti-clockwise position
switches the circuit into a 2:1 ration expander.


THR

Provides threshold control over 70dB in two overlapping ranges.

The -30 button adds -30dB to the panel values.

RGE

Sets the range (mute depth) of the gate over a 50dB range.

FAST

Changes the attack time for the circuit from 1ms to 100us.

REL

The release time for the gate/expander is continuously variable from 30ms to 3s

GATE

switches the gate/expander into circuit separatively from the limiter/compressor.

The limiter /compressor controls are:

L/C

switches the limiter compressor into circuit separatively from the gate/expander.

LINK

When Link button is pressed it links the control voltage of the limiter/compresor to another module for stereo or quad ganging. The control voltage is still generated if the limiter compressor is not in circuit and can therefore be used for stereo/quad link
even if it is not actively processing.

GAIN

Gain makeup of up 30dB is provided to enable an excellent signal to noise ration to be maintened throughout
the path even under heavy compression.

THR

Threshold level can be controlled over 50dB in two overlapping ranges

The -20 button adds -20dB to the panel values.

RAT

Controls the compression ratio with a conveniently arranged law betweeen 1:1 and limiting.

Fast

Nominally changes the impulse attack time from 1ms to 100us. However the attack time is programme dependent, normally having a 7ms time constant, with faster time constants being applied to transient programme.

REL

The release time can be varied from 30ms to 3s with the additional benefit of automatic hold and impulse release circuits to remove pumping
and breething effects.

AUTO

Switches the release control to a triple time constant program dependent release time.


Gain reduction Led

A simple metering fonction is performed by the tri color Led .
The led indicate Green for a small gain reduction, orange for medium and red for large (1, 5 and 10dB respectively).
