HI all.

I have two Flex, one is Analogue Balanced(TRS) version, and another is Digital(SPDIF/TOS) version.

I have simple problem and question.

I guess if I use Flex digital version, I could reduce latency that Flex make.

But digital in/out Flex may have almost same latency of Analogue in/out.

The latency was about 3.1~3.5msec. 

1) Analogue in / out  : TRS in -> FLEX -> TRS out
2) Digital in/out        : Tos(optical) in -> Flex -> Tos out ( I connected flex to RME ADI-2 PRO FS. RME ADI-2 PRO's have under 0.1msec latency of AD-DA converting.)

Filter, PEQ, delay, gain and so on were not applied.
Analogue in /out worked like AD/DA converter and Digital in/out worked like digital pass through.

1) and 2) cases showed almost same latency when I measured.

Is there any way to reduce latency of Flex Digital in-> Digital out?

Please give me some advice.

Thanks in advance
