DYN2000
FRONT PANEL DESCRIPTION
Expander/Gate Section
A noise gate is a signal processor that turns off or
significantly attenuates the audio signal passing
through it when the signal level falls below a user
adjustable threshold.
1. Expander/Gate Threshold Control and LEDs
This control adjusts the threshold of the gate, basically
determining how much of the input signal will pass
through to the output. When the threshold control is
in the OFF position, all signals are allowed through
the gate. Turning it all the way clockwise will ensure
only signals over the +15 dB are allowed to pass
through, affectively limiting the noise level. The two
LEDs indicated when input signals are above (green
LED) or below (red LED) the selected threshold.
One way to easily and effectively set the gate
threshold is to first turn this control to the OFF
position. Play your audio through the DYN2000 and
turn the threshold control up until the red Gate LED
comes on. This is helpful in removing hiss from tape,
guitar amps, and so forth.
NB.
The DYN2000’s expansion ratio is internally fixed to
approximately 10:1, helping to eliminate residual noise often
associated with gating.
2. Sidechain Enable Button
This switch enables the sidechain, allowing users
to use the 1/4” TRS sidechain connector on the
rear of the DYN2000 to send their signal to external
processors and receive the processed signal back.
If there is nothing connected to the sidechain loop,
this button has no affect.
3. Expander/Gate Release Control
This control sets the speed at which the gate closes
once the input or sidechain signals fall below the
selected threshold. Set this control to a slower setting
if vocals or acoustical instruments are used; set to
fast for tighter percussion.

4. Contour Button
Push this button in to ensure the DYN2000 is less
sensitive to low frequency energy, ensuring there’s
no loss of audio – particularly helpful when using
mixed program material.
Compressor Section
Compressors are signal processors that reduce
signals over a user-defined threshold by a user-
defined amount/ratio.
5. Gain Reduction Meter
This meter gives users a visual ideal of how much
the signal is being attenuated by the compressor and
gate functions.
