1500 ARRAY (serv.man11) - JBL Audio User Guide / Operation Manual. Page 6

Due to the weight of the 
1400 Array horn module, it 
is packed separately from 
the low-frequency enclosure. It
is a very simple procedure 
to install the module, and the
necessary instructions are
listed below. The required
Allen-tipped screw driver is
included in the accessory pack.

1. Carefully remove the horn

module from the packaging
and place it face down on a
soft surface.

2. Locate the cardboard

accessory sleeve and
remove the hardware.

3. The accessory sleeve should

contain:

a. 2 Long 1/4" x 20 Allen 

head bolts

b. 1 Short 1/4" x 20 Allen head

bolt

c. 1 Logo plate
d. 1 Rubber hole plug
e. 4 Metal coasters 

(to protect wood and tile
floors from the spike feet)

4. Carefully unpack the low-

frequency enclosure and
place it upright. It would be
helpful to position it near its
final position in the room
since it is much easier to
move without the additional
weight of the horn module.

5. Notice the two threaded

inserts on the angled face 
of the top and also the small
L-bracket on the top. These
are the attachment points for
the horn module. Imme-
diately adjacent to the L-
bracket is a recessed con-
nector which will make the
electrical connection for the
horn module.

6. Although the module can 

be installed by one person, 
it is easier if a second set 
of hands are available.

7. Cradle the horn module with

the opening along your fore-
arm and, using your free
hand, connect the plug
coming from the bottom of
the horn assembly into the
jack on the top of the
enclosure.

8. You can now place the horn

in position on top of the
enclosure. The L-bracket 
fits in an opening under the
horn assembly. The module
will sit on top of the enclo-
sure by itself, although it
should always be steadied
until fully mounted.  

9. Line up the two mounting

holes on the lower lip of the
front of the horn with those in
the enclosure. Partially install
one long bolt and then the
other one. It may 
be necessary to lift the horn
slightly so that the bolts
install smoothly. Do not force
or cross-thread them.

10. Once both bolts have been

started, work them in all of
the way, but do not tighten
them securely just yet.

11. Install the remaining short

bolt in the hole at the bottom
rear of the horn module. You
can fully tighten this bolt. 

12. Now completely tighten the

two front bolts.

13. Everything should be tight

and properly aligned at this
time. If not, loosen, realign,
and retighten as required.  

14. The final steps are to

remove the backing from the
logo badge and place it in
the recess on the lower horn
lip and to use Rubber Hole
Plug to hide the hole at the
bottom rear of the horn
module. Do not complete
these steps until the system
has been turned on and
tested acoustically. Make
sure the horn module is
playing first. Once the logo
badge and rubber hole plug
are installed, it is extremely
difficult to remove them.
