N Gauge DCC/DC Diesel Sound
Decoder with 28 Functions
Item #0001644-2 (Kato SD70 MAC & AC4400)
Thank you for purchasing this MRC DC/DCC Diesel sound
decoder. This dash 2 version has 4 prime mover sounds recorded
directly from the real SD70 and other type of locomotive. All
notching along with increased speeds were also part of the
recording process. Unlike some others, we do not use simply
increase volume or frequency of the prime mover sound to
simulate the notching process. The decoder has presets for all
of its functions, so no adjustments should be required. However
if you wish to make changes, this decoder has a full range of
options
•Digital Signal Process (DSP) and reverb effect
•Built in four types of synchronized diesel prime mover
sounds to choose from
•Built in 34 user selectable different horns and 8 bells
•Lifelike, randomly associated locomotive sounds
•28 accessory functions allowing more sound control
than ever
•Programmable individual sound volumes
•1.0 amp capacity
•Directional headlight and rule 17
•2-digit (1-127) or 4-digit (1-9999) address
•Supports full read back of CV’s
•Programmable start and top voltage
•Programmable acceleration and deceleration rate
•Programmable 14, 28, 128 speed steps
•Supports speed table
•Supports advanced consisting (CV19)
•Supports programming on the main (OPS mode)
•Compatible with NMRA DCC standards
•Built a10mm, 32 ohm speaker
• Directly replaces Kato SD70MAC and AC4400 PC
boards
SPEED TABLE CV67-CV94 FOR 28 SPEED STEPS
When CV29’s bit 4 is set to “1” it will use the speed table formed by CV67-
CV94 to control speed (motor voltage). It allows you to setup each speed for
all 28 speed steps. First, program CV29 to 18 for short addresses (1-127) or
program CV29 to 50 for long addresses (128-9999) to enable speed table
control. Then select throttle to 28 speed steps and run your loco at speed step
1. Use program CV on the main to change CV67’s value (1-255) to adjust step
1’s speed. The kick voltage, CV65 is only applied when the speed step
changes from 0 to 1. You should switch between 0 to 1 many times to check
step 1’s speed. When done with CV67, select speed step 2 and program
CV68. CV68’s value must be greater then CV67’s. When done with CV67-
CV94, use read back CV to make sure their values are in increasing order.
Note: When using MRC Prodigy DCC to program addresses it will automatically
disable the speed table (set CV29’s bit 4 to “0”). Programming CV125 to 1 will
also disable the speed table and re-program CV67-CV94 to a default linear
speed setting.
TROUBLE SHOOTING
Whenever the decoder doesn’t work please use the program track to program
CV# 125 with value 1 to restore the decoder to factory settings. This should
bring the decoder to life with address #3. This decoder should perform well
with all DCC systems. The maximum DCC output should be less than 15 V. If
the locomotive does not respond to commands, it may have lost its address.
Please re-program the address and program CV19 to 0 (disable consist). If it
responds slowly, you should clear its momentum by reprogramming CV3 and
CV4 to zero. If step 1’s speed is too high, you should program start voltage,
CV2 to zero. If its top speed is too slow, program top voltage CV5 to 31. You
should also clean the track to improve electrical pickup. Read your DCC
system manual to learn how to program and operate the decoder. For more
information about registers/CVs and their functions, please refer to the NMRA
DCC Standard & Recommended Practices, RP-9.2.2. This is available directly
from the NMRA or their website at www.nmra.org.

DIESEL SOUNDS FUNCTION CHART
Note2: when CV122=3 (manual notch up/down, F8 will notch down and F9 will
notch up.Bell, Dynamic Brake and Rail Wheel Clack cannot play at the same
time. If you activate the Bell sound [F1], while either the Dynamic Brake or Rail
Wheel Clack sounds are in use, the Bell sound will override the other 2 sounds.
Rail Wheel Clack cannot play while the loco is in idle. When you turn off
Dynamic brake and Rail Wheel Clack sound there will be one second delay.
Although there is a 32 ohm speaker included, the amplifier can handle 8 or 16
ohm speakers, if you wish to change it.
INSTALLATION
Your new MRC 0001644 Sound Decoder will virtually “drop-in” to a Kato SD70MAC
& AC4400 diesel locomotive. Although easy, please follow instructions carefully.
Remove the locomotive body following Kato’s instructions. Remove the original
circuit board by very carefully sliding the circuit board slightly to the rear of the
chassis. Lift out. The 0001644 sound decoder is installed in the same location.
First, deburr the chassis (with emery cloth) any casting flash that may cause a
sharp edge under the location of the insulation tape. Then, using electrical or
equiv plastic tape, carefully tape the chassis in the areas as indicated (See fig 1
& 2) to isolate the decoder from the chassis. This must be done to prevent damage
to the decoder. Align the decoder and carefully insert it in the slots in the chassis.
Gently press down on the rear (speaker side) of the decoder while sliding it into
position, being careful not to bend the PC board and the vertical copper motor
contacts on the side of the chassis. Ensure the vertical copper contacts (on the
decoder) cover the thin vertical motor contacts. The motor contact must not touch
the loco chassis. Remove the white protective film from the speaker and “stick” it in
place as shown. The decoder installation is complete.
When replacing the body, ensure the copper contacts on the trucks are under the
horizontal chassis contacts.
Fig 1.
MAKING A TEST TRACK
When you complete the decoder installation, we strongly recommend
building a test track with a 27 ohm resistor to limit current. Only test
your installed decoder on the test track. The test track may prevent
damage from an incorrectly installed decoder.
Note: The program track is NOT a test track. The program track does not use a
current limiting resistor. So it can’t protect an incorrectly installed decoder.
TESTING
All MRC decoders have been factory programmed with address #3, 28/128
speed steps and maximum top voltage. Never run the installed decoder on
your layout without first successfully running on test track. Otherwise,
you may damage the decoder if it is not wired correctly or if you have not
properly isolated the motor, chassis and lights.
To test, place the loco on the test track. Select the “Run” mode of your DCC
system and select or acquire address #3. Move up the throttle and the loco
should move forward. Push the light button [F0] and the front headlight should
come on. Change the direction of the loco and the loco should change direction
and the rear headlight (if equipped) should come on. The loco cannot reach full
speed, due to the resistor. If all above occurs, you passed the test. Congratula-
tions!
Do not run the loco for an extended period of time on the test track or
the resistor will overheat.
If your installed decoder does not pass the test, find the problem, correct it and
test it again.
DCC OPERATION
This decoder has start up and shut down feature. You must press any function
key to start up the engine before operating the loco. To shut down the engine you
must bring the loco to idle and then press F8, 3 times.
DC OPERATION
The 0001644 decoder provides synchronized diesel rumble sounds with DC
operation. Bells, horns, etc., cannot be accessed. However, use of the MRC
Tech 6 Sound Controller 2.0 (0001200) will enable the full range of sounds on a
DC system.
CAUTION:
The decoder must be isolated as shown. Apply electrical tape or plastic
equiv.) tape in the areas shown in red to prevent the electrical contacts
from touching the chassis and damaging the decoder.
