Attenuation questions for CMVS and supergun (for RGB output and cabling)

[Arcade-Projects]

Hi - I've been reading various threads on the dangers of not attenuating RGB output from PCBs and the Neo Geo. It's not something i gave much thought to but in retrospect perhaps i should, and maybe others haven't too.

I have a JNX CMVS and Raijin/Hakuryu supergun, (both of which are fantastic!).

I run my CMVS into a BVM monitor (via BNC cables) and the supergun into a Framemeister and OSSC. The BNC cable does not have any resistors or capacitors (not attenuated) but the BVM seems fine with it.

Hopefully someone can tell me whether:
(1) I need capacitors and resistors for these two machines on the cables/connectors or whether they are unnecessary?

(2) If so, what is recommended and where is the best place to buy them.

(3) Can BVMs generally cope with strong signals or as a matter of course things going into them should be attenuated?

Thanks
