Vh4s effects loop

[V87]

Hi all, quick question regarding the effects loop on the vh4s. If I have a mono effects chain running 4 cable - how would I run the effects into the effects loop to work on all channels all the time ? I don't want to use the channel inserts as I want to have the effects available across all channels. I'm thinking send from the last pedal in the chain would need a y splitter cable then go into both return a and b ? Alternatively, I do have a stereo delay at the end of the chain that I could send stereo into both returns (as opposed to mono, which what I'm currently doing).

Hope that makes sense.

P.S I have looked in the manual and couldn't find anything.

Just a thought.
You need a split box in order to go to A and B. If you get hum, you can get this https://www.lehle.com/de/lehle-p-split-iii
The delay can be put in the parallel loop or after the split box in the serial loop.
I do not run any fx in the loop except delay...
