Dolby surround to work on N330+N150?

Hi!

I have powernode N330 as main player, and powernode N150 as amp for surround speakers. I would like to be able to use these as 4.1 system for movies. I also have subwoofer connected to N330. Unfortunately my projector has no HDMI ARC output so I can't connect it straight to N330. I bought an active HDMI splitter, but it doesn't seem to work with N330. Maybe that's because it's an HDMI ARC input on N330, or the splitter doesn't support the right audio format (it supports LPCM 7.1, Dolby TrueHD / Digital Plus ja DTS-H).

Anyway, there is another HDMI splitter with optical output as well. Would that make any difference if I try to use the optical input of N330 to get the surround working? So in a nutshell, is the problem the HDMI to HDMI ARC connection, or just the codec that the splitter is using? Or maybe something else?

Thanks!

    Hi Jori

    Sounds like your HDMI splitter does not support ARC and would require a full HDMI extractor that supports ARC, which usually would run you into the $200US/€220 range...

    If you can run optical from the source to the front POWERNODE, you should receive DOLBY - you may have to set the source to PCM. If you need further troubleshooting, drop us a note by selecting Help, Send Support Request in the BluOS App along with the makes and model numbers of your external gear and our Support Crew can assist further.

    What you can try is use a HDMI extractor that has an optical output. Those start at around 20 Euro, though I have had bad experiences using such a model with an Audiolab amp. The POWERNODE wasn't too happy either, though it fared better IIRC. Maybe bad luck, maybe typical of cheap HDMI extractors. I did switch to a better model which works fine.

    Basically you'd go from the source via HDMI into the extractor, and then via HDMI into the projector. The optical out of the extractor goes into the POWERNODE. This is the setup that I am using (it works for surround too), as the HDMI ARC of my TV does not let through anything but PCM 2.0.

    Yeah, thanks! Actually that's what I did after trying 2 different hdmi splitters without an optical output. Bought a cheapest one from Amazon with the toslink, and now it's working with 5.1 sounds. Great!
