RD0465 (A) JFL SERIES OWNER’S MANUAL Page 9 of 18
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.
