rms Voltage Limit:
80 V
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. The powers listed in the table are calculated as the
square of the rms voltage limit divided by the sub-system’s nominal impedance (Z) in ohms.
5.7 INPUT CONNECTIONS
JFL210 and JFL118 loudspeakers utilize Neutrik® Speakon® STX Series connectors. The STX
Series’ all-metal housings are extremely rugged, and feature a built-in gasket providing weather
protection to IP54. Note that only the NLT4FX in-line cable connector will provide rated protection
against the elements.
5.7.1 JFL210 Input Connections
There are two Neutrik NLT4MP connectors on the rear of each JFL210. These connectors mate
with Neutrik NLT4FX, NL4FC, and all other NL4-compatible in-line cable connectors. The
following subsections describe the electrical connections for each operating mode.

NL4 #1: Use as the input to the JFL210.
NL4 #2: Use the second connector to loop the full
range signal to the next JFL210. Note that
an additional signal can be carried on pins 2
+/- without affecting the operation of the
JFL210.
