STACKING INSTRUCTIONS

System Examples (Continued)

Using the MATE, go to the stacking menu (explained earlier in the “Stacking Instructions” section). You are now at the 1

stacking

rank slave. If it’s anything other than 1 appears press the INC

or DEC buttons to make it 1. Press the PORT button to talk to the port 3 FX. Press the INC button to change the “power save level
slave adjust only” to 2 which is the 2

rank slave. Press the PORT button to talk to the port 4 FX. Press the INC button until the

setting is 3 for 3

rank slave. Now you’ve set the rank for all the slaves. If you have more FX’s in the system then press the PORT

button to access the next FX and press INC until the number on the screen is 1 number less than the port number (i.e. if you are on
P05, the number on the screen should be 4).
Let’s back track a little by going to the “POWER SAVE LEVEL MASTER ADJUST ONLY” menu. Do this by pressing the DOWN
button, TOP button, then DOWN button. Verify that the screen you are on now is the “POWER SAVE LEVEL MASTER ADJUST
ONLY” screen and change the port to P01. Turn on all of your FX’s AC Output breakers. The master FX’s “Inverter” LED should be
solid and all the slaves “Inverter” LED’s should be blinking. Adjust the “POWER SAVE LEVEL MASTER ADJUST ONLY” from 0 to 1
and watch the 1

slave’s “Inverter” LED go solid. When the “Inverter” LED is on solid, this means that the inverter is on. When the

“Inverter” LED on the slave is blinking, this means the FX is asleep. Adjust the “POWER SAVE LEVEL MASTER ADJUST ONLY” to 2
and watch the 2

slave’s “Inverter” LED turn on. Adjust the “POWER SAVE LEVEL MASTER ADJUST ONLY” to 3 and watch the 3

slave’s “Inverter” LED turn on. If you have more than three slaves then keep increasing the value in the “POWER SAVE LEVEL
MASTER ADJUST ONLY” screen and verify that each slave’s “Inverter” LED comes on as expected. You have now verified that all
FX’s are stacked correctly so adjust the “POWER SAVE LEVEL MASTER ADJUST ONLY” back down to 0 and have fun with your
system!

STACKED SYSTEM USING OUTBACK’S “SERIES / PARALLEL” STACKING

This type of system may have between 2 and 10 FX’s that will have their AC Outputs connected to one of two Legs. I am assuming
that half of the FX’s will be connected to each AC Output Leg. Actually, it is acceptable to divide the FX’s between the two Legs in the
way you see fit, but at least one FX must be on each Leg. We will be using a Quad-Stacked (4 FX) system with two FX’s on each Leg
in this example. When we set an FX as “OB Slave L1” this indicates that it is in parallel (on the same Leg) with the master FX. When
we set an FX as “OB Slave L2” this indicates that it is in series (on the opposite Leg) with the master FX. If you have a different amount
of FX’s than the four FX’s in our example or if you are overloading one Leg of your system, then you might be putting the slave FX’s on
different Legs than what is shown in the example. We will try to alleviate any confusion when we get to the part of the process where
this is important. The sentences in italics are intended for instructions on systems that are different than the example.
In a quad stack, I am assuming that the top FX is plugged into port 1 of the HUB, the 2

FX down is plugged into port 2, the 3

down is plugged into port 3, and the 4

FX down is plugged into port 4 (again, the location of the FXs is not a rule, just for simplicity).

Using the MATE, go to the stacking menu (explained earlier in the “Stacking Instructions” section). You are now at the 1

stacking

menu called “Stack Phase”. In the upper right hand corner of the mate screen will always be the HUB port number of the FX you’re
working with at the time. Let’s start out with the FX that’s on port 1. If something other than P01 appears in the upper right hand corner
then press the PORT button until P01 appears. Set the “Stack Phase” of the port 1 FX to “1-2 PH Master”. Press the PORT button and
verify that the label in the upper right hand corner displays P02. We are still in the “Stack Phase” menu but we are now talking to the
FX on port 2. Push the INC button two times to set the “Stack Phase” to “OB Slave L1”
If you have a system with only two FX’s or you wish to put the FX connected to port 2 in series with the master, push the INC button
one additional time (three times total) to set the “Stack Phase” to “OB Slave L2”.
Press the PORT button again to talk to the FX on port 3. Push the INC button three times to set the “Stack Phase” to “OB Slave L2”
If you wish to put the FX connected to port 3 in parallel with the master, push the INC button only two times to set the “Stack Phase” to
“OB Slave L1”.
Press the PORT button again to talk to the FX on port 4. Push the INC button three times to set the “Stack Phase” to “OB Slave L2”.
Again, if you wish to put the FX connected to port 3 in parallel with the master, push the INC button only two times to set the “Stack
Phase” to “OB Slave L1”. Any additional FX’s in the system can be programmed by pressing the PORT button to get to the next FX
and then press INC two times (“OB Slave L1”) for parallel stacking or press the INC button three times for series stacking. In this
example, we’ve set 1 FX (P02) to be in parallel with the master (P01) and 2 FX’s (P03 & P04) to be in series with the master.
Press the DOWN button 2 times to get into the “POWER SAVE LEVEL SLAVE ADJUST ONLY” menu. This menu allows you to set
the order in which the slave FX’s come “On”. Press the PORT button until P03 is displayed in the upper right corner of the screen.
We’re starting out with port 3 because the FX on port 3 is the first slave that is in series (“OB Slave L2”) with the master.
