AVOID ELECTRIC SHOCK DO NOT PERFORM INSTALLATION UNLESS QUALIFIED TO DO SO. REFER ALL

SERVICING TO QUALIFIED SERVICE PERSONNEL.

Items included in your KDC 6 kit:

(1) KDC 6 Printed circuit board (PCB) with wires installed

(1) Input/Output (I/O) panel

(2) #4-40 x ¼" screws

(3) tie-wraps

Note: Contact your Rane dealer for missing items.

Tools needed:

#2 phillips screwdriver

#1 phillips screwdriver

small blade screwdriver

needle nose pliers

diagonal wire cutters

I/O Panel Exchange Procedure:

1. Unplug the MA 6S from the AC power source.  IMPOR-

TANT: Wait ten (10) minutes before starting the installa-

tion of the KDC 6 for the power supply caps to safely

discharge.

2. Disconnect the inputs and speakers from the MA 6S by

unplugging the Euroblock connectors.

3. On a sturdy flat surface, place the MA 6S upside down

with the bottom facing up.

4. Remove the bottom cover. This is held in place by (16) #6

thread-forming screws. (12) of these screws are located on

the bottom surface which is now facing up. (2) more

screws are located on each side of the unit. See drawing

522-221 for more details.

5. Remove the I/O panel. This is held in place by (8) #6

thread forming screws and (12) #4-40 x ¼" screws.

Remove all (20) screws. Put them in a safe place, you will

need all the #4 screws and (7) of the #6 screws for re-

assembly. Remove the I/O plate. Keep this panel if you

might convert the MA 6S back in the future. See drawing

522-221 for more details.

6. Install the new I/O panel on the MA 6S unit in the same

orientation the original I/O panel was. You will note that

the new I/O panel does not cover up the silkscreened

information and mounting hole for the KDC 6. Replace (7)

#6 thread forming screws and (12) #4-40 x ¼" screws that

you removed in step 5 above. See drawing 522-222 for

more details.

7. The I/O panel exchange is complete. Proceed to the next

section to install the KDC 6 PCB.

Installing the KDC 6 PCB:

1. Confirm that the MA 6S is off and unplugged, and  the I/O

panel exchange is completed.

2. Referring to the included diagram (see drawing number

522-223), connect the wires from the KDC 6 to the correct

locations on the MA 6S. Orient the KDC 6 with the

component side of the PCB facing up (towards the bottom

cover) while doing this.

3. After all wires are connected correctly to the power supply

PCB of the MA 6S, install the KDC 6 into the MA 6S

chassis with the 3-station Euroblock connector protruding

out the rear of the chassis. The components of the KDC 6

circuit PCB should be facing up (towards the bottom

cover). Make sure the holes in the chassis of the MA 6S

align with the threaded holes on the L-brackets of the KDC

6 and install (2) 4-40 x ¼" screws through the chassis into

the L-brackets. See drawing 522-222 for more details.

4. Using the included plastic tie-wraps, bundle the wires of

the KDC 6 neatly and route them away from any sharp

objects.

5. Reinstall the bottom cover using the (16) screws removed

in step 4 of the I/O panel exchange procedure. See drawing

522-221 for more details.

6. You are now done with installing the KDC 6. See the next

section on power supply connection.
