2. INTRODUCTION The JFL Series is a compact format, constant curvature line array system for venues with listener distances up to about 45 m / 148 ft. It is designed to be incredibly simple to deploy, yet provide the highest output possible from a compact line array format. The Series includes the 2-way JFL210 full-range loudspeaker and the complementary single 18 inch JFL118 subwoofer. -

Weight of the array 4.2 GROUND STACKING Normally, a ground-stacked JFL Series main array is used where suspension is not possible, too difficult, or too time-consuming. JFL210 – with or without JFL118 – are also quite effective when used in stage side fill or audience front fill applications. -

This may be implemented in a DSP (Digital Signal Processor), equalizer, or amplifier with integrated high pass filter. The recommended filter is 60 Hz, 12 to 24 dB Butterworth. Page 8 of 18 RD0465(A) JFL SERIES OWNER’S MANUAL... -
Page 9: Signal Processing
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. -

JFL210 is operated in bi-amp powering mode. HF shading functions are instead replicated in DSP. Recommended settings are available on the EAW website. In an array where some JFL210s are being used for short to medium distances and some are used for long distances, it is appropriate to use multiple HF outputs in DSP to implement mixed shading. -

CAUTION: The rms voltage limits listed above are related to the thermal limits determined from EAW’s standard power test. In this test, transducers are “exercised” to a point of damage or failure. The test signal has a 6 dB crest factor (peak to average ratio). A maximum continuous voltage limit for the loudspeaker is then determined based on the test results and on the transducer’s application in the loudspeaker. -

NL4 #3: Use as a loop-through, high-passed connection to JFL210 or other loudspeakers. 6. RIGGING & HANDLING JFL Series arrays may be suspended via M10 mounting points or the accessory FB121 Fly Bar, ground- stacked, tripod-mounted, or pole-mounted. This manual will cover suspension using M10 mounting points and tripod / pole mounting applications. -
