Stacked, With LFE and Speaker-Level Inputs to PS1400 and Internal
High-Pass Signal Output to PT800
Use this installation method
with the PT800 and PS1400
stacked.
By using the PS1400’s internal
crossover to process the full
range output of your receiver
or amplifier, the Performance
speakers can behave as a
single full-range system and
produce the highest quality
of sound reproduction that
makes the best use of each
transducer component of each
module. In addition, the LFE
(low-frequency effects)
channel provided by some
digital sources can be mixed in
with the low-frequency signal
to provide effects that add
excitement and realism to
movie soundtracks, musical
performances or other
materials.
Do not use the PS1400’s
internal crossover and
speaker-level outputs unless
the PS1400 and PT800 are
stacked. If the PT800 is placed
separately – on the wall, on
a shelf or on a stand – you
must use your receiver or
processor’s crossover, which
should be set to 80Hz.
The
reason for this is that the
PS1400’s internal crossover is
set at 130Hz, and was custom-
designed around the precise
location of the PT800 module
on top of the subwoofer.
This installation method should
be used for digital surround-
sound formats, such as Dolby
Digital or DTS
® , where the
receiver or processor has a
subwoofer output or a volume-
controlled preamp (line-level)
output.
1. Configure the receiver/
processor for “Large”
speakers for the left and
right channels.
2. Configure the receiver/
processor for “Subwoofer On”.
3. Configure the receiver/
processor for “Small” for the
center and rear channels.
4. Check the owner’s guide for
your receiver or amplifier to
make sure that the main
speaker terminals will output
a full-range amplified signal.
Connect your receiver or
amplifier’s left and right
speaker terminals to the
binding posts marked
“System Input”
¶
on your
corresponding left and right
PS1400 subwoofer modules.
5. Set the PS1400’s crossover
switch
™
to the “Normal”
position. This will cause the
PS1400 to provide an electronic
130Hz crossover for the
subwoofer that matches the
passive 130Hz crossover point
at the output to the PT800 tower.
6. Set the Polarity (phase)
switch
¢
to Normal, since all
amplifier channels will be in
phase, and in the stacked
configuration, sound-wave
cancellation will not be an
issue.
7. Connect the receiver/
processor’s LFE or subwoofer
output to the LFE Input
§
on
your left and right PS1400
subwoofer modules. If your
receiver/processor has only
one output jack, use a
Y-connector (not included).
Plug the male end of the
Y-connector into your
receiver/processor’s
subwoofer output jack, and
connect each of the two
female ends to separate RCA-
type patch cords, then plug the
RCA-type patch cords into the
LFE inputs of the PS1400
modules.
8. Remove the JBL logo plate
from the mounting plate on top
of the PS1400 by gently prying
it upwards. This will expose
the binding post output
terminals that will provide the
signal for the PT800 module. It
is easiest to connect the gold
jumper bars between the
terminals on the top of the
PS1400 and the terminals on
the rear of the PT800 by
completely unscrewing the
binding post collars first. Insert
the closed loop at one end of
the jumper bar over the PS1400
output terminal, and insert the
open end of the bar around the
PT800’s input. Screw the
collars back onto their
respective posts.
