mark 1V effects loop question

Hi I have the B version amp and have just bought a TC g major to replace my G system because i wanted more floor effects on a pedalboard . and a need to have alighter rig for rehearsal.
In looking at the connections for the G major and the programming it has different reccomendations depending on if the loop you put it intyo is series or paralell . After a search through here and the manual i cant see which the boogie is and thefore if i need to use this killdry option on the unit. anybody know if the mark4's loops are series or paralell ?

Best regards


Mark

Serial, which is good. Parallel bad. Muy mal.

All Mark IV's are series loops
