I think that info came from REL and not Arcam.From whats been posted you are absolutely right. Utter nonsense as usual from Arcam. They really have no idea what they are doing.

But surely this bass will have been EQ'd by Dirac? That's the point REL are trying to make I think. So the Sub will only be playing EQ'd FL/FR bass at whatever hi-level crossover point you set on the REL. You just have to make sure the fronts are both set to Large when you run Dirac as well as during playback.Then, I will add the high level input back in, and put a load of bass on top of that which will not be Dirac'd.
Yes, the front mains are always set to largeBut surely this bass will have been EQ'd by Dirac? That's the point REL are trying to make I think.

Think about what is being sent to the REL once back in situ via high level - it will be the bottom end of the FR at whatever hi-level x-over you set on the REL. But of course this has already been Dirac'd because that was how you would have run the EQ initially. So only the EQ'd low frequencies for FL/FR will pass through to the REL via high level.This is an interesting discussion, I am struggling to grasp it though. How will the bass that is being played by the sub via the high level input be Dirac'd, if the high level input is not connected when Dirac is run?
No, REL are saying to run Dirac with the high level input NOT connected.But of course this has already been Dirac'd because that was how you would have run the EQ initially. So only the EQ'd low frequencies for FL/FR will pass through to the REL via high level.
Yes, sure so Dirac corrects the entire freq range. But you then obviously re-connect it during playback!No, REL are saying to run Dirac with the high level input NOT connected.
How will it correct the whole frequency range if the high level is not connected? My front mains don't go down that low, they will roll off around 60hz or so, whereas the sub plays down to 10hz or lower!Yes, sure so Dirac corrects the entire freq range.

I see what you mean now. Yeah, might only be useful for those who have front speakers which go down much lower.How will it correct the whole frequency range if the high level is not connected? My front mains don't go down that low, they will roll off around 60hz or so, whereas the sub plays down to 10hz or lower!
Even for those front speakers that do go down lower, once the high level is added back in, the volume of those frequencies will be different, ie louder as the sub and the front mains might be duplicating some of the audio around the crossover point, and the nulls and peaks will be different on audio that is emanating from the sub than it will be for the audio emanating from the main speakers.I see what you mean now. Yeah, might only be useful for those who have front speakers which go down much lower.
That is interesting, I might give it a go next week, thanks for the info. It seems like a bit of a 'hack' but I would have thought that Rel should know a thing or two about bass management, so I am curious to see how that method sounds.As the poster of the Rel, Arcam and Dirac post my understanding is that for sub connected to the main front speakers the volume on the sub should be really low in that you shouldn't actually hear the sub, should be just enough volume that it just fills out the bottom end that the speakers can't actually do themselves.
So take the sub front speakers hi level connection out of the Dirac process so the speakers just run as themselves, then after the calibration is finished then just connect the hi level connection again.
The Dirac calibration shouldn't be messed up as there shouldn't be a huge amount of bass being added via the hi level.
I received my AVR850 this week and its a useful boost in SQ over my 9 year old Onkyo as expected. I do have some operational quirks that are a little annoying.
Any suggested workarounds?
- I have an RTI control system which can control the Arcam via RS232 or IP, if I use IP then the app doesn't work as the RTI processor is already connected to it and it only allows one connection. If I use RS232 then the app doesn't work as the IP is turned off.
- Once the control system is in use I don't seem to be able to use the music life app either.
- I have to turn off the control system when its connected IP to use Dirac, or if its connected via RS232 it has to be changed to IP control in the Arcam to liven the network port for Dirac to work.
- I knew the amp channels can't be re-assigned for the Atmos channels which is annoying but the digital audio inputs can't be re-assigned to specific sources either.
Info + Direct.How do I check the firmware version please?
Hi - does anyone know if the AVR390 support DSD over HDMI from a compatible player? The manual doesn’t say anything either way.
It doesn't. I asked that same question of Arcam recently. Below is their reply.......
Hi Steve,
It doesn't have native DSD support. If the unit is connected to a unit by HDMI that can output DSD the source device would understand from the HDMI handshake that it is not a format supported and convert to PCM.
If the source device is outputting analogue from the SACD it will be converting the DSD to analogue and the AVR850 would accept that signal.
Kind Regards,

This was their response to the other question I asked about whether it could happen with a firmware upgrade.......
Sorry I forgot to address the second part of your question about firmware.
Native DSD could not be added via a software update as the HDMI board needs a direct connection to the DAC (not via the DSP) which is not physically present in the unit.
Kind Regards,
Sam Burkin
Why is there no instructions DeanCouldn't resist and ran Dirac 2.1.2, everything went fine, just wondering if I've done it right. Once the measurements were done and filters calculated I was presented with the graphs, on the old version I'd then be given the option to optimise, I couldn't find any option to optimise on this version though? Just exported and it went through OK. Have I done it right or missed a stage? I must admit I expected better instruction.
