APPLICATION
LSS’s TREX is an arrayable 2-way horn-loaded long-throw loudspeaker
system designed for a wide range of medium to long-throw applications. The
LSS’s TREX tightly defined coverage pattern allows seamless integration
into array clusters, which may be tight-packed for long throw or splayed for
broader coverage. This systems was designed for a wide range of
professional applications. The TREX powering mode is only bi-amplified
operation with external digital processor.
The TREX is ideal for concert touring applications, the 13° per side
trapezoidal angles match the 60° horizontal coverage pattern allowing the
creation of tight packed clusters. The comprehensive system fly points
mounting tracks allows safe suspended installations.

INSTALLATION AND WIRING
TREX can be installed stand alone or in stack configuration, in most cases
with SUBTREX subwoofer. It must be installed only in vertical position.
In the bottom of the case there are two plastic skeeds used as feet to
support the speaker.
If installation is in stacking mode, plastic skeed fit on the recesses placed in
the top of the case placed beneath.

______________________________________________________________________________
Operating Manual ver. TREX-EN-1.1 |9
In addition, it can be installed suspended through the mounting brackets
placed inside the case.
There is a total of eight brackets inside the case: four in the top and four in
the bottom. Each bracket is secured to two adjacent internal side of speaker
using two M10 screwbolts.
If needed, replace the screwbolts with eyebolts.
More detailed:
Two brackets are connected between top and left side of case.
Two brackets are connected between top and right side of case.
Two brackets are connected between bottom and left side of case.
Two brackets are connected between bottom and right side of case.
When installation is in suspended mode, use the upper or lower brackets.
Unscrew one of the two screws hold a single bracket, the second screw
must be screwed only after the first one has been tightened to avoid the
bracket moves.
It is possible to install a maximum of three speakers in cascade using
eyebolts.
Use plugs suitable to support the weight of the entire apparatus.
Speaker can be suspended too using the flying tracks placed in the sides
and rear of the case. Multiple flying tracks allow to choice the position and
inclination of suspended speaker.
Before making connections between mixer and speakers, make sure the
mixer volume is turned down.
In the connection panel there are two Speakon NL4 connectors 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 other systems.

For a correct operation, use a 4-poles cable. Two different channels are
necessary to make speakers works. One channel for LF and another one
for HF. Internal connection are made as follow:

TREX system operating mode is only Bi-Amp (LF 1- 1+; HF
2- 2+) and needs an external digital processor with custom
setup provided by LSS. on request it is possible to ask
setting parameter in order to use third part processor. If
your amplifier can manage a 2 Ohms Load and has
sufficient power, it is possible to connect a maximum of 4
speaker in parallel (total impedance will be 2 Ohms).
Before making connections between mixer and speakers, make sure the
mixer volume is turned down.
You can now use the system

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. Verify that
the amplifier (+) terminals are connected to pins 1+ and 2+ of the
NL4 connector and the amplifier (-) terminals are connected to
pins 1- and 2- of the NL4 connector.
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.
