6 JL AUDIO ZR650-CSi
CROSSOVER NETWORK ADJUSTMENT
The ZR crossover networks have been designed
to allow tonal adjustments to the upper midrange
response and tweeter level. These adjustments
make it possible to fine-tune your system to suit
your listening preferences and to compensate for
various speaker mounting applications.
ADJUSTABLE MIDRANGE PRESENCE:
Your ZR crossover networks provide a unique
midrange presence control, located under the
clear cover. The midrange presence is selectable
via a set of pins and allows for four settings. These
settings affect the amplitude of the upper midrange
response of the ZR component woofer. We
recommend that you begin your listening with the
factory setting (3) and adjust up or down as needed
to compensate for mounting location, orientation or
personal taste.
ADJUSTABLE TWEETER LEVEL:
ZR crossover networks also provide five levels
of tweeter adjustability designed to compensate for
different mounting locations, vehicle interiors and
personal taste. These levels are selectable via a set of
pins located under the clear cover of each crossover
case. We recommend that you begin listening in the
“REF” (Reference) position. To find the optimum
tonal balance in your installation, experiment with
alternate tweeter level settings by moving the jumper
connector. It is safe to switch jumpers while the
system is playing.
TWEETER PROTECTION:
The ZR crossover networks are equipped with
an advanced electronic tweeter protection circuit
designed to minimize the possibility of tweeter failure.
This electronic device monitors current going to the
tweeter and will disconnect the tweeter from the
signal when it senses overload. Should this occur
while listening to the audio system, simply reduce the
volume for a few seconds and the protection circuit
will reset itself automatically.
