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.
6. Compressor Threshold Indicators
These three LEDs indicate the relationship of the input signal level
to the threshold of compression. The green BELOW LED is On
when the signal is below threshold and the red ABOVE LED is On
when the signal is above threshold.
Note: Even when no input signal is received, these LEDs may flicker when
the power is activated or deactivated.
7. Compressor Threshold Control
This control allows users to adjust the level at which compression
to the input signal will kick in, thus avoiding distortion and protecting
your amplifier and speakers. Turning it clockwise will raise the
threshold, thus squeezing signals at a higher level and reducing
the amount of compression applied to the signal.

8. Hard Knee Button
With this button pushed in, the DYN2000 applies a hard-knee
style of compression to the input signal. What this means, exactly,
is that when the signal level reaches the selected threshold, the
compressor will kick-in instantly and start compressing the signal
at the selected threshold. When released, however, a soft-knee
style of compression is used, basically easing into the compression
just prior to hitting the threshold.
9. Ratio Control
This allows users to adjust the ratio between the input signal
received by the DYN2000 and the compressed output signal.
When this rotary VR is set to 1:1, there will be no compression
applied to the signal. When it is set at 2:1, any input signal over
the selected threshold is compressed to half. When it is set to ∞:1,
any signal over the threshold setting will be completely removed
(affectively making the compressor a 'limiter').
OUTPUT
This diagram shows typical compressions at various ratios.
10. Compressor Attack Control
This control allows users to adjust the speed at which the
compressor function will take effect after a signal above the
selected threshold has been detected. A fast attack time will be
more noticeable, but will control excessive peaks much easier.
A slower attack time, however, will be far less audible and still
successfully compress excessive signals.
