Band Gain controls
Once you have chosen the range(s) and determined the Level, you control the action of the
DNS3000’s filter bank using the Band Gain controls.
The six faders represent six frequency bands distributed from lower frequencies (left) to higher
frequencies (right) across the selected range.
You will use the Band Gain controls to control the amount of noise attenuation performed in
each band, adjusting them to suppress as much noise as possible without introducing unwanted
artefacts into the desired signal.
Noise suppression occurs in a given band when the fader is below the 0dB line. However, there
are occasions when you might wish to boost the signal in a given band, and you can do this by
moving the appropriate fader above the 0dB line.
Activity LEDs
The twelve Activity LEDs offer a visual indication of the activity in each of the six bands
controlled by the Band Gain controls.
■
Both LEDs off: Less than ±0.5dB activity
■
Green LED lit: The signal is being attenuated
■
Red LED lit: The signal is being boosted
The brightness of an LED offers an indication of the amount of attenuation or boost applied.
Each band controls numerous filters. Therefore, the Activity LEDs in a given band display the
overall activity in that band, and are not necessarily indicative of the action of any single filter at
that moment.
Bypass
You can route the input directly to the output by pressing the Bypass button. This allows you to
switch off all processing, regardless of any other settings, either on the DNS3000 itself
(including the in-built scenes and automation) or obtained by remote control. The signal latency
is not affected by the Bypass state.
This control affects both channels regardless of the status of the channel selection buttons.
The Bypass button flashes slowly to indicate an I/O error such as no lock.
