APPLICATION
LSS's PULCEW is a compact subwoofer system that provides response in
the 40-180 Hz range. It can be configured on request in stereo mode or
mono mode.
LSS's PULCEW uses two 160mm (6") low frequency cone with 38 mm
(1.5") voice coil for better performance in permanently installed applications.
PULCEW offers passive powering mode, band pass mechanical filter and
the internal crossover network for satellite out. PULCEW performs well with
PULCE loudspeakers to form full-range reproduction systems, and is also
compatible with other LSS small mid-high loudspeakers in permanent
installations.
PULCEW-EQ on request can be made with passive equalization circuit for
satellites.

INSTALLATION AND WIRING
PULCEW can be installed on the floor or on other table.
.
PULCEW stereo has four couples of Black and Red clamps in the
connection panel.
Two of them are connected to the right speaker while the other two are
connected to left speaker.
Considering only two couples of Black and Red clamps (right or left), the
bottom couple is the input, the upper couple is the output.

PULCEW mono instead has two NL4 speakon connectors in the connection
panel referred as ‘IN’ and ‘OUT’.
IN is the input connector and must be connected to the amplifier, ‘OUT’ is a
LINK OUT and can be connected to satellites.
Recommended configuration using multiple speakers with PULCEW in
MONO Mode is represented below:
Choose a safe mounting location, so as to prevent the cables can be
stepped on or create tripping hazards.
Before making connections between mixer and speakers, make sure the
mixer volume is turned down.

TROUBLESHOOTING
Problem
Possible cause(s)
Action
1. No Sound
Amplifier
Connect a known working test speaker to the amplifier outputs. If
there is no sound, check that all the electronics are on, the signal
routing is correct, the source is active, the volume is turned up,
and so on. Correct/repair/replace as necessary. If there is sound,
the problem is in the wiring.
Wiring
Verify that you have connected the correct wire pairs to the
amplifier. Play something at low level through the amplifier (for
example, from a CD player or tuner). Connect the test speaker in
parallel with the malfunctioning line. If the sound level has gone
or is very weak, the line has a short in it (possibly a severe
scrape, pinch, or staple puncture). If the sound level is normal,
the wire is open (possibly a cut wire or a missed connection).
Using the test speaker, move down the line and test each
connection/junction until you find the problem and correct it.
Observe proper polarity.
2. Poor Low
Frequency
Response
Speakers wired out-
of-polarity
When two speakers are connected out of polarity, the low
frequencies will cancel each other acoustically. Carefully observe
the wire markings or tracers on your speaker wires.
For PULCEW with SPEAKON terminal:Verify that the amplifier
(+) terminal is connected to pin 1+ of the NL4 connector and the
amplifier (-) terminal is connected to pin 1- of the NL4 connector.
For PULCEW with Black and Red clamps: Verify that the
amplifier (+) terminal is connected to RED clamp and the
amplifier (-) terminal is connected to BLACK clamp.
3. Intermittent
output such as
crackling or
distortion
Faulty Connection
Check all connections at amplifier and speakers to ensure they
are all clean and tight. If the problem persists, it may be in the
amplifier or wiring. See Problem 1 above.
4. Constant
noise such as
buzzing,
hissing,
humming
Defective amplifier or
other electronic
Devices
If the noise is present but no program material is playing, the
likely cause is the signal chain in the electronics. Evaluate each
component as necessary to isolate the problem.
Poor system
grounding or ground
loop
Check and correct the system grounding, as required.
If these suggestions do not solve your problem, contact your nearest LSS dealer or LSS distributor.
