In fact, a multi-channel volume control is a surprisingly hard to get feature when using pro sound cards, while users of AV receivers get it for free, even with a remote control.<br /><br />A low pass filter on MOTU can be approximated using either a peaking EQ with the center frequency set as low as possible, or with multiple shelving filters. But I guess your intention is to have a proper crossover filter which indeed totally lacks from their EQ options. miniDSP products are better suited for this task.<br /><br />As for the volume control, I tried different solutions both in software and hardware. If you plan to do room correction, you might consider AcourateConvolver from AudioVero (maker of Acourate), it works on Windows. In hardware, good affordable solutions are RU-VCA6A from RDL Labs and Volume8 from SPL. The first has several alternatives for adding a remote, while the second has better transparency (lower THD+N), but has no remote options at all.Mikhailhttps://www.blogger.com/profile/03247181793198240403noreply@blogger.comtag:blogger.com,1999:blog-3158263204999873374.post-8008799901589847122022-01-05T09:21:51.555-08:002022-01-05T09:21:51.555-08:00Hello, nice setup!

Seems that Motu AVB generation devices lack some vary basic functions that have been standard for a long time but for some reason is now absent. Other example of these is total lack of low pass filters.Laurihttps://www.blogger.com/profile/02305166776506472873noreply@blogger.comtag:blogger.com,1999:blog-3158263204999873374.post-89492475549924712972020-06-29T10:50:42.926-07:002020-06-29T10:50:42.926-07:00Got it, thank you for your helpGot it, thank you for your helpChamphttps://www.blogger.com/profile/05600365024969789839noreply@blogger.comtag:blogger.com,1999:blog-3158263204999873374.post-43974994899836882402020-06-28T12:46:01.723-07:002020-06-28T12:46:01.723-07:00Frankly, I don't remember why I was using diff...Frankly, I don't remember why I was using different EQ on Sub L and Sub R back then. I don't do that anymore.<br /><br />As for phasing, I think you anyway need to have low frequency part in your L and R channels to be in phase or close to that. This is to avoid problems when summing for the sub and for mono playback.Mikhailhttps://www.blogger.com/profile/03247181793198240403noreply@blogger.comtag:blogger.com,1999:blog-3158263204999873374.post-51844181761768092372020-06-28T12:27:05.069-07:002020-06-28T12:27:05.069-07:00Ah got it, thanks for the help on that, and then a...Ah got it, thanks for the help on that, and then are you eqing Sub L and Sub R separately to avoid phasing?

On the "Mixing" tab you need to split into 2 mono channels one of the mixer inputs and one of the "Aux" busses, by clicking on the two blue dots under the channel name (note that "Group" busses can't be split). Then you set up an "Aux Send" from input L and from input R into the same channel of the Aux bus you've just splitted.Mikhailhttps://www.blogger.com/profile/03247181793198240403noreply@blogger.comtag:blogger.com,1999:blog-3158263204999873374.post-42849333663712894752020-06-27T19:58:03.962-07:002020-06-27T19:58:03.962-07:00How did you mix down the Sub L and Sub R into one ...How did you mix down the Sub L and Sub R into one mono output?Champhttps://www.blogger.com/profile/05600365024969789839noreply@blogger.com
