APPLICATION
LSS's SF15DC is a 2-way self-powered loudspeaker system that provides
high output, low distortion sound reinforcement for the entire range of pro
audio applications. SF15 uses a 380 mm (15") low frequency cone with 75
mm (3") voice coil and Neodymium magnet and 75 mm (3") voice coil high
frequency compression Titanium/Neodymium driver. SF15 is ideal for better
performance in both touring and permanently installed applications. The
SF15A digital amplifier with DSP controller allows the pilotage in BI-AMP
mode 750W for LF woofer + 200W for HF driver.
LSS's SF15DC was designed as main speaker in live events, as monitor
system, front or delay fill and can be used stand alone or with one or more
other loudspeaker to create horizontal array.

SF15DC speaker can be mounted on the floor, on a pole or suspended
through the dedicated hardware.
For installation on a pole, use the pole mount cup in the bottom of the case.
For suspended installation, follow the procedure below:
Insert ALUBAR SF15 in the guide slots on the sides of the case. If one
speaker must be mounted, insert only the ALUBAR in the upper side.
Install the LIFTBAR SF15 on the ALUBAR, then lock them with a M8 BOLT.

______________________________________________________________________________
Operating Manual ver. SF15DC-EN-1.0 |11
Install BUMPER SF15 and connect it with the LIFTBARs using four
GRILLO16. Another GRILLO16 can be used to hook the BUMPER.
Choising different holes in the LIFTBAR, allow to have different degrees of
inclination. Inclination depends too from the way and the number of
speakers installed.
To install more SF15 speaker suspended in horizontal configuration, mount
ALUBAR SF15 in the upper and lower guide slots on the sides of two
adjacent cases.
Install BUMPER SF15 as previously explained and connect it with the
LIFTBARs using four GRILLO16. Another GRILLO16 can be used to hook
the BUMPER

SF15DC_______________________________________________________________________________
12| Operating Manual ver. SF15DC-EN-1.0
For suspended installation in vertical configuration, mount the ALUBAR in
the cases of speakers.
To connect a case with the lower one use the JOINT SF15, then lock them
with the locking pin.
It is possible to install a maximum of three speaker in horizontal
configuration and three in vertical configuration.
Use plugs suitable to support the weight of the entire apparatus.

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.
Check the amplifier is On, the green LED is On and SIGNAL
LED blink. Then control Volume Knobs is open.
Wiring
Verify that you have connected the correct XLR connector to the
amplifier. Play something at low level through the amplifier (for
example, from a CD player or tuner). 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).
2. Poor Low
Frequency
Response
Speakers wired out-
of-polarity
When two speakers are connected out of polarity observe the
wire markings on your XLR connector. Verify that pin 2 is +
terminal and pin 1is - negative.
3. Intermittent
output such as
crackling or
distortion
Faulty Connection Check all connections 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.
