XLD FIR_Drive v2.0 DSP Setting Notes 
11-19-10	MDK

EV XLD loudspeakers provide a unique ability to control the horizontal dispersion pattern down to fairly low frequencies. The presets provided in this folder provide several options. The XLD281 provides 120 degrees of covereage and the XLD291 provides 90 degrees. It is important that you match the loudspeaker setting to the speaker. Do not apply XLD281 settings to and XLD291 loudspeaker.  

The XLD-FIR v2.1 presets provide improved polar and acoustic response while allowing the speakers to be used in multi-pattern XLD arrays without special settings. 

Subwoofers are time-aligned and level-adjusted to be flown in the same array. The subwoofer level is set for a 1/4 ratio of subwoofers to top boxes. Subwoofer output level and alignment delay may need to be adjusted for your application.

We created these settings for use with the TG-series amplifiers equipped with RCM-26 DSP cards and Dx46 processors. These FIR_Drive settings also include the ElectroVoice PA Limiter and TEMP Limiter which can only be used with FIR_Drive processors. 

These settings are not for use with the Netmax N8000 System Controller. At this point the TEMP limiter is not available in the Netmax N8000. However, additional XLD FIR v2.1 settings are available for use with the N8000 until the TEMP limiter becomes available. The FIR_Drive settings can be identified by the FIR_Drive in the sps file name.
