Record multiple transponders simultaneously

[Akita]

I have now Vu+ dou 2 with 4 tuners.
I have bought Vu+ duo 4k se with a tuner S2X FBC Twin Tuner.
How many transponders can I record on at the same time?
With the Vu+ duo 2 I could record from 4 different transponders at the same time.

How should I configure tuner S2X?
I am watching from a satellite position.

Unless you have a unicable lnb, then you would configure it the same as you did on your duo2 and you can record the same amount of transponders as you could on the duo2 also.
