JBL Northridge E Series E150P - Manual (Page 3)

English
SPEAKER PLACEMENT
• As a general rule, bass
response increases as a sub-
woofer is placed closer to a
wall. Therefore, bass output is
maximized when the sub-
woofer is placed in a corner.
• It is also recommended that
the subwoofer be positioned
along the same wall as the
front loudspeakers.
Low-frequency sounds are nor-
mally omnidirectional, meaning
the listener can’t tell where they
are generated from. However,
frequencies between 75Hz –
150Hz can be localized, espe-
cially at higher volume levels.
Positioning your subwoofer as
recommended will provide the
most natural soundstage and
imaging from your loudspeaker
system.
Remember that these are just
guidelines. Since every listening
room is different, JBL strongly
recommends experimenting
with the positioning of your sub-
woofer to obtain the most pleas-
ing results in your room. One
technique that can help you find
the ideal subwoofer location is
to temporarily place the sub-
woofer near the main listening
location. Then move around the
room and determine where you
hear the most pleasing bass
performance. This would then
be the ideal location for the sub-
woofer.
When we designed the E150P
and E250P powered sub-
woofers, our goal was to offer
the user the best possible per-
formance combined with the
most flexible and complete
installation options. Please look
over the following three exam-
ples to determine which
description best matches your
system and follow the corre-
sponding hookup instructions. To use the binding-post speaker
terminals with bare wire,
unscrew the collar until the hole
through the center post is visi-
ble under the collar. Insert the
bare end of the wire through the
hole in the post, then screw the
collar back down until the con-
nection is tight. The holes in the
center of the collars are
intended for banana-type con-
nectors. To comply with European CE
certification, these holes are
blocked with plastic inserts at
the point of manufacture.To use
banana-type connectors
requires the removal of the
inserts. Do not remove these
inserts if you are using the
product in an area covered by
the European CE certification.
ANALOG RECEIVER/PROCESSOR –
SPEAKER LEVEL CONNECTIONS
Use this installation method
with an analog receiver/
processor that does not have
digital processing or bass
management, and also does not
have a subwoofer output or a
volume-controlled preamp
(line-) level output:
Connect your receiver or ampli-
fier’s front left and right speaker
terminals to the left and right
terminals on the subwoofer that
are marked “High Level In.”
Connect the left and right termi-
nals on the subwoofer that are
marked “High Level Out” to the
cor-responding terminals on the
back of your front left and right
speakers.
Connect your receiver or ampli-
fier’s center, left and right sur-
round-speaker terminals to the
corre-sponding terminals on the
back of your center, left and
right surround speakers.
