Factory Digital Signal Processing Settings. EAW JFL SERIES, Loudspeaker's

A DSP with two outputs is required to operate the JFL210 in bi-amp mode or to operate a JFL210 in single-amp mode with a JFL118 subwoofer. A DSP with three outputs is required to operate the JFL210 in bi-amp mode with a JFL118 subwoofer.

The block diagrams in Figure 5.3 show the possible signal flows for a single JFL210 with JFL118.

Use the same processor outputs for additional JFL210s and JFL118s on the same mix bus, i.e.

“Left”, “Right”, or “Fill”.

5.4 SIGNAL PROCESSING

5.4.1 Factory Digital Signal Processing Settings

Factory DSP settings are available for download at http://www.eaw.com/downloads/ . The signal processing adjustments determined by EAW for JFL Series products should be fully implemented

“as is.” Array performance, in terms of frequency response, beamwidth consistency, output level capability, and wavefront coherency is dependent on the EAW engineered crossover and other processing settings. These settings are determined from extensive measurements in laboratory environments and in typical venues. As such, they will normally provide excellent results in a variety of venues.

5.4.2 Non-EAW Digital Signal Processors

Even though non-EAW Digital Signal Processors can be set to numerically equal values, the actual transfer function (magnitude and phase) of the processing depends on the particular digital processor. The reason is that different algorithms can be and are used to implement the same processing functions. The factory settings were determined using EAW’s UX8800 Digital Signal

Processor. If you will be using a non-EAW DSP, contact EAW about its compatibility with the

EAW factory settings.
