Hello, I’ve got a few questions about Room EQ and crossfeed I was hoping someone could answer. Any assistance would be greatly appreciated. For context, I currently have an original UCX (so I can’t experiment for myself in TotalMix) but am considering an upgrade to the UCX II.

When crossfeed is enabled on a pair of channels being used in stereo configuration, is it still possible to use separate Room EQ and 3-band EQ settings for each of those channels? Or does enabling crossfeed link the EQs? I have a set of per-channel EQ curves from a custom Sonarworks headphone calibration that I’d be recreating a simplified version of, and I’d also like to use crossfeed.

I saw it mentioned that the 9-band Room EQ and crossfeed are both behind the additional 3-band EQ in the signal path, but I’m unclear on the order of the first two. Is the 9-band EQ after the crossfeed?

And finally, is there information published somewhere about the technical differences between the 5 crossfeed settings?

+ "And RoomEQ saved in Snapshots is a newer TM FX feature, not yet mentioned in manuals."

Hello, I am considering to buy UCX II exactly due to the standalone Room EQ feature - with EQ it became very relevant due to its small size and 20 output channels.  I would like to clarify some confusion after I read through the latest UCX II manual and all these Room EQ threads:

1 - does UCX II really have 20 independent output channels where all 20 output channels get the Room EQ?  (I am asking, because the current manual still states "A maximum of 16 channels of Room EQ")

2 - Are the Room EQ presets saved in Snapshots, just like 3-band EQ? This is super-important as I would like to switch Room EQ snapshots using ARC USB buttons.  (again I am asking, because the current manual still states "its settings are only saved in the Workspace")

3 - Any chance to add at least one all-pass filter or "phase rotation" in the Room EQ? (I can accept the 9-12 bands of EQ even if it is quite limited compared to many DSPs with 30 PEQs. What I am struggling with is how to do precise phase alignement for fully active speakers and multiple subs without all-pass filter or a "phase rotation" feature)

thank you.

Thank you for clarification.  Not the best news, especially that all-pass filters are not to be expected in RME devices, but at least I understand what I am getting into.

Will try to make it work

Hello!

Could somebody please confirm if Room EQ on UCX II is available in standalone and in Class Compliant modes?

Can it be configured without TotalMix, using only the display on the device itself?

Thank you.

Do I have any chance, that instead of "Shelving" there will be the choice of "Low Shelf" or "High Shelf" for each of the three "free" filters? I desperately need 3 Low Shelf filters for one output channel and currently this is the "Game Over" for my intended pure Total Mix Crossover Setup for my 4 way active speakers...

Found a workaround for the "too less shelving filter" topic, but still it would be nice.
Unfortunately I found another show stopper, which is that there is no option for Butterworth 1. Order. For Highpass below 500 Hz it's available with the "LC" functionality, but for higher frequencies or Lowpass behavior, I see no option.

I know that crossovers is not the intention of all these functions, but if you can "unlock" a whole new market with some simple adaptations, why not?

That is well known and will not change.

Ok, I have to correct myself, a LR12 can indeed be done since the filters are minimum phase. A combination of the BW2 HP/LP (Q=0.7) with a Peak Filter (Q=0.6) at the crossover frequency does the trick to a precision of 0.2 dB - if anyone else is interested.
