Carefully begin to remove the grill. The
grill has a tendency to want to “pop
out,” so please be sure to hold the
grill in place with your free hand while
removing the screws with the other
hand. Do not fully remove the grill as the
cable is still firmly attached to the led
PCB assembly.
4
Carefully remove the cable attached to
the led PCB assembly.
5
Use the phillips head screwdriver to
remove one screw from the center of the
led PCB assembly.
Five screws need to be removed from
each side of the grill (ten screws total)
using the phillips head screwdriver.
Keep the ten screws in a safe place.

Carefully remove the led PCB assembly
from the back side of the grill.

The hard part is done, the rest is easy!
Place the new led PCB assembly (part
#0007334) where the old one was. Follow
the same steps as above, but backwards
6 to 1. Power up the SR1522z and the led
should light up. Congratulations, you just
replaced an led PCB assembly...now go
play some shows!

The grill support is covered with a
rubber strip. The four screws may be
accessed by either: (1) peeling back
the rubber strip, or (2) puncturing a
hole through the rubber strip where
the screws are located with the phillips
head screwdriver. The grill support is
easily removed by pulling it off of the
cabinet. Don’t forget to screw the grill
support back in place once the woofer is
replaced!

Four nuts and eight washers may be
removed from the driver using the
8mm open end wrench. Turn counterclockwise to loosen and remove,
clockwise to tighten. The other three are
located around the horn assembly. Lift
the horn up as the nuts are loosened. It
cannot be removed otherwise. Notice
that the flat washer is on the bottom,
followed by the locking washer, and
finally the nut.
8
Keep the four nuts, four locking washers,
and four flat washers in a safe place.

The horn assembly should easily lift right
off of the high frequency driver.

Four headless screws need to be
removed from the high frequency driver.
Pliers could help if the screws are too
tight. Turn counter-clockwise to loosen
and remove, clockwise to tighten. Keep
the four headless screws in a safe place.
Place the new high frequency driver
(part #0008093) where the old one
was. Follow the same steps as above,
but backwards 10 to 1. Power up the
SR1522z and the new driver should now
be pumping out those highs again.
Fantastic, you just replaced a high
frequency driver!
14
Diaphragm replacement:
1
At the present time (December 2006),
diaphragms are not currently available,
so you will have to replace the complete
driver following the previous section
(pages 10-13). If you have received
a diaphragm, please follow the steps
below.

Follow steps 1-5 of the high frequency
driver replacement instructions, as the
horn will need to be removed in order to
access the diaphragm.

This is what the plate adapter and
diaphragm look like after they have
been removed from the horn assembly.
The diaphragm is separated from the
plate adapter simply by pushing down
on the terminals.
This is what the diaphragm (left) and
plate adapter (right) both look like. Place
the new diaphragm (part # coming
soon) where the old one was. Follow the
same steps as above, but backwards 6
to 1. Power up the SR1522z and the new
diaphragm should now be pumping
out those highs again. Sweet, you just
replaced a diaphragm!

The covers may be worked loose by
wedging a flat head screwdriver in
between the cabinet and the cover, as
well as the amp assembly and cover.
Make sure to get around the entire cover
plate in order to liberate them.

Fourteen screws need to be removed
from the amplifier assembly using the
phillips head screwdriver. The amplifier
assembly is capped by two cover plates
outlined above.

Once the two cover plates are removed,
two more screws need to be taken out in
order to separate the amplifier assembly
from the cabinet. Keep the two screws in
a safe place.
The amplifier assembly is now ready to
be separated from the cabinet. Do not
completely take the amplifier assembly
off yet, as five cables need to be
removed first (as shown above):
(1) led PCB cable, (2) blue and black,
(3) solid blue, (4) solid black, and (5)
solid yellow. Do not force cable removal
or connection, although needle-nose
pliers may aid in loosening the crimped
cables.
Caution: The amplifier assembly is
approximately 18 pounds, so please
make sure to grasp it firmly.

the amplifier assembly. The cable only fits
in one way.

See the pictures to the right for the
closeups of the woofer and high
frequency driver terminals. Make sure
the cables are reconnected to the same
terminals they were removed from (but
on the new amplifier assembly). Once
again, they are: (2) blue and black, (3)
solid blue, (4) solid black, and (5) solid
yellow. Do not force cable removal
or connection, although needle-nose
pliers may aid in loosening the crimped
cables.

Place the new amplifier assembly
(part #0014138-00) where the old one
was. Follow the same steps as above,
but backwards 7 to 1. Remove the
serial number from the faulty amplifier
assembly (as shown in picture above)
and place on the new amplifier
assembly. Power up the SR1522z and
relish in the fact that you just replaced
an amplifier assembly. Hats off to you for
a job well done!
9 Important:
The faulty amplifier
assembly must be returned to LOUD
Technologies. The address should
be on the return shipping label that
was provided with the new amplifier
assembly. If not, the return address is at
the top of this page. Also, please write
the order number and service request
number (ex: 1046256-1203935) in big,
black, bold numbers on the outside of
the box. This helps expedite the return.
