Trigger Input Voltage NAP250

[NaimDude]

Hi everyone,

just bought a new classic NAP250 and it’s absolutely fantastic with my Kudos Titan 505. My source is a Eversolo DMP-A10 and I connected both via the Trigger In-/Outputs, but the NAP250 refuses to turn on when the Eversolo is switched on. One can use an electrical or optical 3,5mm connector, I used the electrical version and it didn’t work. Does anyone know, if the NAP250 needs a certain input voltage? The Eversolo delivers 12V.

Thanks for your replies!

They are not 12v triggers on the NC250 but automation ports for connection to other Naim products. Why not put the NC250 into auto standby ? It will switch out of standby when it senses an input signal and then switch back to standby after ~19 mins without a signal.

The 250 is of course designed to work with a Naim system, for which it is supplied with an optical cable. Have you tried that with your Eversolo? Whether the amp is capable of understanding commands from non-Naim equipment I have no idea.

[NaimDude]

Thanks for your reply. The NAP250 is in “Auto Stby”, but is not switching on automatically, when a signal comes in.

[NaimDude]

Thanks for your reply. Yes, I tried that and it didn’t work.

You have to power off the NC250 completely if you’ve changed the auto-standby switch setting. There were some issues with some NC250s (i had this on mine) whereby auto-standby was not working so this may be the case. In all cases, disconnect the trigger in / outs as it’s not designed to work with the Eversolo.

I did power off the NAP250 completely, thanks for the hint, but it doesn’t switch on anyways. The trigger in/outs are disconnected now.

Interesting - it may be the NC250 has an issue as did a couple of others who were using the auto-standby function with a non Naim source, rather than using the system automation connection within a full Naim system.

NC 250 Auto Standby not working?

Folks, I’ve been enjoying my NC250. It’s a cracker of an amplifier and I’m really pleased with it. One slight fly in the ointment is that after warming it up for a few days in Instant On mode, the Auto Standby functionality doesn’t seem to work (rear switch changed from Instant On to Auto Standby). I’m not using it in a Naim system so there is no optical comms connection, but even so, in this mode it should go into standby after ~19mins of no signal and then come back on when it senses a signa…

I now have NC350s and the auto-standby function works really well.

[NaimDude]

Yes, that could be one of those units. Have to check if it turns automatically off after 19 mins.

Are you actually giving the 250 a signal to wake it when in Music Sensing mode?

I use system automation now with a NAC332 but remember when I used mine with a NAC282 I had to turn the volume up more than I expected to ‘wake’ the 250 from its standby slumber.

[NaimDude]

Thanks for your reply. I turned the volume up quite a bit. Dead silence.

[NaimDude]

Okay, now it works. I had to unplug the Eversolo to install a SSD memory card and after that the NAP250 turned on as it sensed a signal and it went automatically in standby without it. Sometimes it’s strange. Thanks y’all for your help!
