Hi - does anyone know the best/safest way to wire a JVS New Net City for JAMMA, specifically the sound? I have a RiverService JAMMA conversation harness (https://www.rs2006.co.jp/e/jamma_harness/index.html) but the sound goes to RCA connectors that are meant to go into the NNC amp, then to the speakers.
I believe this might create issues because sound is already amplified on the JAMMA board, and it would then be amplified again by the NNC amp.
I have read that an audio line out converter / high-low converter could work (by lowering sound power into the NNC amp) (http://www.ms-line.co.jp/original_hi_low_21hl_20gl.html) but would there be any risk to the JAMMA board (e.g. Somehow the converter stresses the JAMMA board amp)?
Another option could be to create a connector that takes the RCA connectors from the JAMMA harness and connects directly to the NNC speakers. This would bypass the NNC amp. Is this an option/advisable?
Any expert advice would be appreciated.
Thanks
