This type of system may have between 2 and 10 FX’s that will have their AC Outputs connected to the same Leg.  We will be using a 
Quad-Stacked (4 FX) system as an example.  If you have less than four FX’s then any reference to FX’s on ports greater than the 
amount of FX’s in your system will not apply to your system.  If you have more than four FX’s then follow the natural pattern of 
programming that will become apparent in this example.   
In a quad stack, I am assuming that the top FX is plugged into port 1 of the HUB, the 2

nd

 FX down is plugged into port 2, the 3

rd

 FX 

down is plugged into port 3, and the 4

th

 FX down is plugged into port 4 (This 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

st

 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”.  Press the PORT button again to talk to the FX on port 3.  Push the INC 
button 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 two times to set the “Stack Phase” to “OB Slave L1”.  Now you’ve set 3 FX’s (P02-P04) to be in parallel with the master (P01).  If 
you have more FX’s in the system then program them as “OB Slave L1”.   
Press the DOWN button 2 times to get into the “POWER SAVE LEVEL SLAVE ADJUST ONLY” menu.  Press the PORT button until 
P02 is displayed in the upper right corner of the screen.  This menu pertains to the slaves only which is why we’re starting out with port 
2.  The setting from the factory should be already set to 1 which is the 1

st

 rank slave.  If it’s anything other than 1, then 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

nd

 rank slave.  Press the PORT button to talk to the port 4 FX.  Press the INC button until the setting is 3  

for 3

rd

 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

st

 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

nd

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

rd

 

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!   

This type of system will include only three FX’s and must be set up as described here.  Turn off all AC Output and AC Input breakers 
before powering up FX’s.  In 3-phase stacking, I am assuming that the top FX is plugged into port 1 of the HUB, the 2

nd

 FX down is 

plugged into port 2 and the 3

rd

 FX down is plugged into port 3 (This is not a rule, just for simplicity).  The HUB has a jumper on it that 

needs to be changed for 3-phase stacking (refer to the HUB manual).  Using the MATE, go to the stacking menu (explained earlier in 
the “Stacking Instructions” section).  You are now at the 1

st

 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 “3ph Master”.  The Master FX is considered phase A.  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 five times to set the “Stack Phase” to “3ph Slave”.  Now you’ve set this FX (P02) as phase B, producing 208VAC between itself 
and the master (P01).  Press the PORT button again and verify that the label in the upper right hand corner displays P03.  We are still 
in the “Stack Phase” menu but we are now talking to the FX on port 3.  Push the INC button five times to set the “Stack Phase” to “3ph 
Slave”.  Now you’ve set this FX (P03) as phase C, producing 208VAC between itself and the master (P01) and also 208VAC between 
itself and the FX on phase B.  The next two screens in the STACK menu do not apply to a 3-phase system, so you need not worry 
about them.  Remember that the AC input to a 3-phase system must be a 3-phase source (generator or grid).  Have fun with your 
system!
