Behringer NU3000DSP Parametric EQ Control View, Parametric EQ Frequency Curve Display, Dynamic EQ

13iNUKE NU6000DSP/NU3000DSP/NU1000DSP User Manual

•Frequency Curve—displays the filter curves in visual form, and allows click-and-drag manipulation of EQ frequencies and gain.

The Frequency Curve and Control View interact with each other and simultaneously shift as you change parameters in either view.

Parametric EQ Control View

The Control View of the Parametric EQ tab contains virtual knob controls for Gain, Frequency, Quality (parametric EQ only). Exact parameter values appear in boxes below each virtual knob. These parameters may be altered by either adjusting the virtual knobs or by entering values directly in the parameter boxes.

To activate an EQ band, click the button (Filter 1, Filter 2, and so on) at the top of each channel strip. The channel button will light up to indicate the EQ is active.

Pull-down Type menus for each EQ band contain these additional options:

•PEQ (parametric EQ)

•LS6 (low shelving EQ, with a 6 dB slope)

•LS12 (low shelving EQ, with a 12 dB slope)

•HS6 (high shelving EQ, with a 6 dB slope)

•HS12 (high shelving EQ, with a 12 dB slope)

Parametric EQ Frequency Curve Display

The Frequency Curve displays a frequency range from 20 Hz to 20 kHz, with 15 dB of cut/boost displayed on the vertical axis. Within this graphic field, the EQ curve appears as a solid fill above and below the 0 dB center line and running from left to right. The curve shifts and moves to reflect changing parameter values. Dotted vertical lines indicate frequency points for the various EQ bands, numbered 1 through 8, and these frequency points can be selected and moved through the frequency spectrum using the mouse or trackpad. The gain for each EQ band may also be adjusted by using the frequency lines.

Adjusting Parametric EQ frequency via click-and-drag

1.Click and hold on the numbered box at the top of the desired EQ band frequency line.

2.Drag the frequency line to the desired location on the frequency spectrum.

3.The EQ curve shown by the solid yellow fill will move and adjust as you shift the frequency line. The virtual knob and frequency displayed in the Control View will also simultaneously change as you move the frequency line in the Frequency Curve.

Adjusting Parametric EQ gain via click-and-drag

1.Click and hold over the numbered box at the top of the desired EQ band’s frequency line.

2.Move the cursor vertically up or down the frequency line to the desired gain level.

3.The EQ curve shown by the solid yellow fill will re-size and adjust as you move the cursor up and down the frequency line. The virtual gain knob and gain dB displayed in the Control View will also simultaneously change as you move the cursor up and down frequency line in the Frequency Curve.

4.Dynamic EQ

The Dynamic EQ tab displays and controls DEQ DSP module settings in two formats (similar to the Filter/Crossover and Parametric EQ tabs):

•Frequency Curve—displays the layered dynamic EQ curves in visual form, and allows click-and-drag manipulation of dynamic EQ/filter frequencies and gain.

•Control View—allows parameter tweaks via virtual controls, as well as pull-down menus for EQ/filter type (Type) and gain reduction/boost ratio (Ratio).

The Frequency Curve and Control View interact with each other and simultaneously shift as you change parameters in either view.

Dynamic EQ Frequency Curve Display

The Frequency Curve displays a frequency range from 20 Hz to 20 kHz, with layered dynamic EQ curves. Within this graphic field, the dynamic EQ curves appear as solid yellow lines that appear at every 10 dB (0 to -50 dB) threshold on the vertical axis. The curves shift and move to reflect changing parameter values. Dotted vertical lines indicate frequency points for the various dynamic EQ bands, numbered 1 and 2 (per channel), and these frequency points can be selected and moved through the frequency spectrum using the mouse or trackpad. The gain for each dynamic EQ band may also be adjusted by using the frequency lines.

Adjusting dynamic EQ frequency via click-and-drag

1.Click and hold on the numbered box at the top of the desired dynamic EQ band frequency line.

2.Drag the frequency line to the desired location on the frequency spectrum.

3.The layered dynamic EQ curves shown by the layered yellow lines will move and adjust as you shift the frequency line. The virtual knob and frequency displayed in the Control View will also simultaneously change as you move the frequency line in the Frequency Curve.
