1x XLR input on NAP 250DR

maybe a stupid question, but can anybody tell me how to connect a pre amp with 2x XLR outputs to a NAP 250 DR ( 1x XLR input)? and, what are the disadvantages here?

XLR connectors are normally used for making balanced (rather than single ended) connections between equipment. It’s not a true balanced input on the 250 - it uses an XLR socket but wired with pin 1 as gnd, 2 as Ch1 and 3 as Ch2. I would use the unbalanced (single ended) outputs (on RCA connectors) on your preamp and use a custom 2x RCA to XLR cable to connect your pre to the 250.


Was about to say the exact same thing, so I’ll just concur.

thanks for your info.

You’d need a custom-made cable for connecting a non-Naim preamp to NAP250.
Not that common… but I think Chord may have something available.

Have a look at a company called flashback sales they sell a vast array of cables including specialist Naim types. I found them when looking for an XLR cable for the pre out on my 172.

I have no affiliation and have not dealt with them yet so please do your own research.
