IMPORTANT SAFETY INFORMATION | ENGLISH 15

2. INTRODUCTION
Congratulations on purchasing a FOHHN®LC loudspeak-
er system. LC loudspeakers are passive, weatherproof line
source systems with aluminium housing, specially designed
for use in fixed installations where the highest demands for
speech intelligibility and visual appearance must be met.
They are equally suited to indoor or outdoor use.
LEN loudspeaker systems feature two-way technology with
integrated passive filters that guarantee an even disper-
sion and the best possible coverage. An integrated FOHHN
SOURCE DIVISION WAVEGUIDE effectively suppresses side
lobes, resulting in improved speech intelligibility for acousti-
cally challenging venues with long reverberation times, such
as railway stations, airports, auditoria and conference halls.

SETUP AND OPERATION | ENGLISH
3. SETUP AND OPERATION
3.1 INSTALLATION AND MOUNTING
Depending on the particular model, LC loudspeakers can
be mounted on building structures using the following wall
brackets (see Chapter 5 “Accessories”):
WAL1, WAL03, WLX100, WLX221
Loudspeaker mounting within buildings should only be car-
ried out by trained personnel.
Please ensure that the wall brackets you have selected are
suitable for use with the product to be installed.
We recommend that you read Chapters 1 and 2 of this user
manual carefully. You must also observe any relevant na-
tional safety requirements.
CONNECTION TO BUILDING STRUCTURES
• Make sure that the building structure to which the loud-
speaker will be connected is statically suitable.
• Surfaces that support brackets must be sufficiently sta-
ble and not be subject to long-term settlement.
• Wall plug and screw connections must be of sufficient
size to cope with the tensile strength required. This will
also depend on the type and inclination of the particu-
lar speaker mounting.
• If you are uncertain about any of the above points, it
is imperative to consult a qualified structural engineer.
CONNECTIONS BETWEEN LOUDSPEAKERS AND
BRACKETS
• All FOHHN brackets include fastening materials for
connecting them to the loudspeaker. If you want to use
other screws, their strength must be at least class 8.8;
this corresponds to a tensile strength of 800 N/mm² and
a 0.2 % proof stress of 640 N/mm².
• Never use screws that are longer than the originals
supplied. This could damage structures inside the loud-
speaker, or cause a short circuit.
• When connecting the following brackets to LC series
loudspeakers, a tightening torque of 10 Nm is required:
WAL1, WAL03, WLX100, WLX221. This applies to
standardised screws without washers: DIN 912/6912,
DIN 931/933, ISO 7380.
SAFETY
• Regardless of any currently applicable legal require-
ments, we strongly recommend securing all systems to
a second separate point. Any M6 thread points on LC
loudspeakers are suitable for this purpose. The two sets
of threads above the connection panel and on the up-
per end of the housing rear wall are specifically intend-
ed for this.
• DIN 580 C15 forged eyelets can be used for anchoring
the system. SEE FIGURE 1.
• To secure the loudspeaker, only suitably sized permit-
ted elements (such as wire ropes, shackles or quick
links) should be used. The maximum falling distance,
before the safety element is engaged, should be as
small as possible and must not exceed 200 mm.
Figure 1
17
• When anchoring the system to the wall, dynamic
strength caused by the falling loudspeaker must also
be considered.

SETUP AND OPERATION | ENGLISH
MOUNTING WITH WAL1 BRACKETS
1. Remove the two oval-head screws from the top and
base of the loudspeaker.
SEE FIGURE 2.
2. Fix both WAL1 brackets to the wall using two screws
and wall plugs in each case. The loudspeaker itself
serves as the best distance gauge.
When mounting the longer LC150 and LC220
loudspeakers models, it makes sense to fix the low-
er bracket first and determine the position of the top
bracket using the actual loudspeaker.
Allow play of ca. 2 mm between the loudspeaker
and the bracket.
3. It is advisable to affix the supplied rubber wash-
ers around the drill holes on the top and bot-
tom surfaces of the speaker. This will prevent
the powder coating from becoming scratched.
SEE FIGURE 3.
4. Slide the loudspeaker between the two brackets.
5. Screw the brackets to the loudspeaker using the sup-
plied M6x25 screws and washers. Do not tighten the
screws at this point.
Apply medium-strength thread lock fluid to both
screws beforehand.
6. Adjust the loudspeaker then firmly tighten both screws
according to the required torque.

MOUNTING WITH WLX100 / WLX221 WALL BRACKETS
1. Remove both oval-head screws M6 (D) at the mount-
ing plate and loosen the screws (C, F, G) by about three
turns.Removethemountingplatefromthewallbracket.
SEE FIGURE 4.
2. Remove the fourto six M6 oval-head screws thatare lo-
cated underneath the connector panel. SEE FIGURE 5.
3. Fix the loudspeaker to the WLX100/WLX221 mount-
ing plate. Apply medium-strength thread lock fluid to
all screws. On both brackets, use four of the locking
screws you just removed. Tighten all screws according
to the required torque. SEE FIGURE 6.
4. Fix the WLX100 or WLX221 to the building structure
using two screws and wall plugs. To do this, you will
need to disassemble the mounting bracket from the wall
bracket. During installation, don‘t forget to place the two
tooth-lock washers (A) between the mounting bracket
and the wall bracket. Make sure that the wall brack-
et is mounted with the horizontal slot facing upward.
SEE FIGURE 7.
5. Put the mounting bracket in a roughly vertical position by
turning the adjustment spindle (B) to the right.
6. Place the loudspeaker and its mounting plate on the
wall bracket. Both sides of the mounting plate must be
resting on the screw (C). SEE FIGURE 8.
7. At this point the fixing screws (D) can be fitted and
tightened with a torque of 8-10 Nm. There are two op-
tions here: If the front holes (20) are to be used, this will
result in an adjustment angle of 0-20°; if the rear holes
(30) are used, this will result in an adjustment angle of
10-30°.
8. Set up the required inclination angle by turning the ad-
justment spindle (B) to the left. If you need to reduce
the angle again, turn the spindle back while pushing
the speaker slightly up towards the wall bracket and
thus releasing the spindle.
9. Loosen the clamping screws (E) on the horizontal axis
and turn the loudspeaker to its required position.
10. Once you are happy with the loudspeaker’s angle and
rotation, tighten the clamping screws (E) with a torque
of 20 Nm. Tighten the screws (C, F, G) with a torque of
8 to 10 Nm.

1. Remove the two M6 oval-head screws that are located
underneath the connector panel. SEE FIGURE 9.
2. Fix the WAL3 to the wall using two screws and wall
plugs. For this, use the part containing the two slotted
holes at right angles.
3. Fix the bracket to the loudspeaker using the WAL3’s
mounting plate. Apply medium strength thread lock
fluid to all screws. Firmly tighten all screws using the
required torque.
4. Tighten the M8 nut (F) just as far as it is still possible to
turn and angle the loudspeaker. Set the required rota-
tion and inclination angles. SEE FIGURE 10.
5. Once you are happy with the above angles, tighten the
M8 nut (F) using a torque of 18 Nm.

SETUP AND OPERATION | ENGLISH
3.2 WIRING
All LC series loudspeakers are passive systems designed
for use with external amplifiers. They have identical ca-
bling connectors and can be supplied with a choice of two
options:
• 2 × 4 plastic terminal blocks are supplied as standard.
These are suitable for wires with a cross section of up
to 4 mm².
• The loudspeakers can also be supplied with 2 × 4 ce-
ramic terminal blocks. These are suitable for wires with
a cross section of up to 2.5 mm².
All cables used must be of an appropriate cross section. We
recommend using ferrules for stranded wires.
A sealing plate is attached to each loudspeaker, along with
two M16 cable glands. Once cabling has been completed,
this can be used to cover the connector panel and provide
tension relief for the cable.
Please be aware of the fact that the specified degree of
protection (in accordance with IEC 60529) is only obtained
by mounting the sealing plate correctly. The cable glands
are suitable for use with cables of between 6 and 10 mm
in diameter.
If only one cable is being used, the other cable gland
should be replaced by the dummy plug that has been sup-
plied with the loudspeaker.
