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').

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.
