Nvs - 4000 in a NAC

[Hrvat9]

I just got my nvs-4000 in the mail and I’m wondering before I tackle this, is there anything I’ll need to make it work? Is it plug and play ?

Congrats on the purchase

You need a specific set of wiring if you have the standard low PSU in your cab.

It came with The top left ac in and out wires but that’s it. I unplugged them and plugged in the wires from my other psu into those slots and the third cable into the dc out 1 and confirmed everything works for some reason, either I was tired or something but the picture looked a hell of a lot better with the bigger psu. Now I need the audio cables which I can’t seem to find anywhere but neo legend, but it says they’re unavailable.

These audio cables are easy to make. I found an old 3.5mm jack to phono cable, and chopped off the 3.5mm jack. I then just crimped on 4 connectors, and fit them into the Amp-Up plug

Everything works including the demag button? For me it didn't with the standard wiring. But I think there are different sets of wiring depending on which PSU your NAC comes with, so it could be different for you.

That easy?? Where would I find that specific amp up connector? I also need the 2 pin amp up for the naomi sound amp

I actually totally forgot to test the service/test/demag buttons -_- lol. I’ll try them out today. One thing I did notice is that the switch on the power supply did nothing :/. The switch on the back of the NAC controlled everything

Here is the exact harness for that PSU: https://www.ebay.com/itm/Sega-Naomi-Har ... SwPYZU-v1q

It has all of the audion cable break outs and wiring to power a Naomi.

Once you wire it all up properly, the power switch will come into play

Buy one of these cables, and cut it in half (you can make 2x cables then keeping 1 as spare): http://uk.rs-online.com/web/p/rca-phono ... s/7424579/

4 pin connector here: http://uk.rs-online.com/web/cp/7100028, ... ?sra=p&r=t

Pins for the connector: http://uk.rs-online.com/web/p/pcb-conne ... s/6831336/

you just need a crimping tool then if you dont have one already?

Hate to bump this thread, but I'm also in the same boat- I've got an NVS on the way but I have the 400-5261 in mine currently. It looks like it should be plug an play except for the monitor.

I ended up using mine in my versus city since the psu blows he fuse. plug and play. Never ended up putting it into the NAC because I put my naomi into the versus
