EAW DX810 instruction manual Crosspoint Matrix Section, Option

reflected in the Crosspoint Matrix Section by “blanking out” all but the top row of crosspoints for the linked crossover outputs. Note that only contiguous outputs may be linked to create a crossover.

Linking outputs together for the crossover automatically links those outputs in Output EQ processors. The Output EQ defaults to the setting for the first output in the crossover (i.e., Output A). The equalizers are located prior to the crossover in the signal chain, so all the outputs assigned to the crossover are affected by the EQ settings.

With the first band active (red active button lit), click the On button to turn the crossover on and off. When the crossover is turned off, all the outputs assigned to the crossover pass a full-range signal. Click the Reset button to return all the knobs for the currently active band to their default settings.

Output: Select the first output for the crossover (A-J). Click the arrow next to the box to select an output in the pull-down list. It appears in the first Output box. Repeat for up to five bands in a single crossover system.

To deselect an output once you've selected one, click the arrow next to the box and select the "blank" line under the J output. This removes the output selection from the crossover.

Polarity: The Polarity button reverses the polarity of the output by 180°.

Edit: Click the Active button under Edit to adjust the settings for the selected output. Then use the Filter Type, Filter Slope, Alignment, Frequency, and Delay Time controls.

Filter Type: Use this control to select high-pass (HP), low-pass (LP), or band-pass (BP) filters for the selected output. Notice that the Frequency control selection changes to High Freq and Low Freq when BP is selected.

Filter Slope: Use this control to choose the roll-off curve for the frequencies above or below the cutoff frequency. When Butterworth or Bessel alignment is selected, 12, 18, and 24 dB/octave slopes are

available. When Linkwitz-Riley is selected, 12 and 24 dB/octave are available (18 dB can’t be selected).

Alignment: This switch selects either Linkwitz- Riley, Butterworth, or Bessel characteristics for the selected Filter Type.

Frequency: This selects the cutoff frequency for the selected filter, with a range from 20 Hz to 20 kHz. When a bandpass filter is selected, High Freq and Low Freq controls are available.

Delay Time: This control adjusts the delay for the selected output in small increments (22.7 ∝s), with a range from 0 ∝s to 997 ∝s. The equivalent distance the sound travels in the selected amount of time is displayed.

Note: This control is provided in the Crossover window because the Delay Line DSP (the Delay button) is situated prior to the crossover in the signal chain. When the crossover is active, use this delay control to adjust for offsets between drivers in a stack. For example, use this control to time-align a horn’s compression driver and a woofer’s voice coil.

This button is reserved for future upgrades.

CROSSPOINT MATRIX SECTION

This section provides a view of all the input-to- output crosspoints in the mixing matrix. It has a numerical and graphical indication of the gain setting for each crosspoint.

Click the associated letter button (A-J) in the Output Section to select an output and the horizontal row of input crosspoints is highlighted. The input faders in the Input Section now control the gain settings and mix for the selected output. Either click on the fader or click on the horizontal mini-fader indicator bar in the crosspoint to adjust the gain for the input.

Click the select (S) button to select the crosspoint for copying or pasting the level. Otherwise, when a group is selected, use it to assign the crosspoint to the selected group.
