Polarity and Pin Designations
A positive voltage applied to the + input terminals produces positive acoustic pressure from the loud-
speaker. The correct wiring of the NL4-type connector is shown in Figure 21.
Recommended High Pass Filters
When operating ENTASYS loudspeaker systems, it is strongly recommend to use an external, active
high pass filter to protect the woofers from excessive low frequency excursion. High pass filters will help protect
the loudspeaker against damage from over excursion and will avoid using amplifier power that's wasted from
attempting to reproduce frequencies below the loudspeaker's intended operating range. A high pass filter set to
at least 200 Hz, 24 dB/octave should be used. Increasing the high pass filter to a higher frequency or greater
slope should not present any problems for the loudspeaker.
