StudioLive RM32Ai and RM16Ai Mixers & UC Surface with QMix Ai

Yup, the RM32AI has been discontinued. Bummed!!!!
Was hoping for a way to bypass the preamps to use a tube preamp on a few tracks here and there. The RML32AI has the option for using Inserts to bypass the initial preamps to use external preamps... oh well. ok I'm venting, ha

I guess I was inquiring if there was a way with the original RM32AI, short of getting an additional RM16AI (to sync), if one could add just an extra 8 inputs, for 40 inputs, even if its just TRS vs XLR inputs? Currently running a DI800v2 8-channel Active Direct Box and all is well, but was hoping to add yet another 8 channel inputs.. via light-pipe, or another way?
Anyone have a suggestion for easily master/slaving/cascading another 8 inputs? Don't need anymore outputs. Just wanting to add another 8 tracks in, if that's an option at all?

Yes, it was and is possible to expand the system up to 64 channels/tracks. You need an AVB Switch for that, because the RM rack mixers are cascaded via AVB. There is some information available on the download page

There are some RM specialists writing for this Facebook group:

It might make sense to consult them... ;-)

Thank you for the quick reply. I will check on the fb page. I was hoping to add a few channels without doing a cascade to another unit that size, as I didn’t need the outputs, just inputs. Some interfaces have the light pipe option, the Rm32ai doesn’t of course, was hoping to find a way short of picking up another rm unit to add channels.

For daw purposes, you can chain any firewire device. Doing it this way, you will not see those channels in UC or UC surface. Something like a Firestudio Project would work

A curious topic to add to this discussion. If going either Dante or AVB to sync/lync my current RM32AI and a RM16AI (considering used) together... I understand that will give additional inputs... will it also show as 48 channels in Universal Control/UC Surface mixer? I use that to send mixes to the headphone amps, so would need those extra 16 channels to be a part of the whole. 32 currently show as only 1 rm32ai.. if adding a rm16ai, will i then have 48 UC channel sliders available to send to headphones?

Casading is possible via AVB (not Dante) and UC Surface will show 48 channels. ;-)

Thank you! more info then I started with.
I'm a little curious... if this is still valid or not, as this screenshot attachment was from a "coming soon" in 2015 doc... is Cascading possible just thru Ethernet, and still show as 48 channels, or AVB the only way to go to get what I'm inquiring on.

I used an MOTU AVB switch for cascading my RM mixers, but because both rack mixers have an AVB enabled option card, it works with just an Ethernet cable. It does need some settings (IP addresses), but I don't know anymore in which manual or document this was described.

I think the screenshot shows something weired, because cascading means that the RM32 becomes the Master and the RM16 becomes the Slave, so it only needs one FireWire connection to the Master rack mixer. The Ethernet connection is also shown wrong. You can not connect a computer via AVB.

that may be something 'intended', but not actual, as it did say "coming in 2015"...
I did find this youtube video: https://www.youtube.com/watch?v=d5BiINY0eoM
that goes over: StudioLive RM Cascading Setup
Will that need to change out the standard default card in the back of each? or good as is?
Sorry for such silly questions, been using the RM32AI 32 channels at once for so long never had a need for more channels at once, but have that need more and more now.

As well as the video above, I located this (attachment), page 4 from:
https://pae-web.presonusmusic.com/downl ... 220151.pdf
Seems to go over it quite well.
Maybe they didnt fully understand the graphic description when initially put out the pdf in 2015, hoping to be able to use straight Ethernet into the router for syncing, but the updated screenshot shows an AVB is required, and that group outputted to the wireless router for iPad and Qmix usage.
I have to think at some point someone must have tried just connecting both RM's into the router (no AVB switch) and hoped for the best. Curious on the failure there, does it just not see each other on UC Surface, or cause nasty noise, etc, etc?

Yes, that's an old video and it basically shows how CS18AI and two RM mixers can be connected. But it is also possible to connect two rack mixers only and use all AVB functionality. This does not allow Remote Control (iPad), but you can and will use UC Surface on your computer which is connected to the Master via a FireWire. The connection between the two mixers can have a distance up to 100 meters. As I wrote earlier, the rack mixers were shipped with AVB-ready option cards, so you don't need to spend additional money. If you think of getting an AVB switch, look for the MOTU AVB switch because it has a dedicated port for a router.

I remember that page in the manual and it reminds me of "old days". I had a RM16AI as second rack mixer (Slave) and of course the MOTU AVB Switch with the router port. But I think you didn't mentioned a CS18AI and remote control. All you need is a direct connection. I modified that passage a little bit to show what I am talking about. If you want remote control, you have to add the MOTI AVB Switch and a router.

Thank you soo very much for the info, a fountain of knowledge!!! Sooo much appreciated on the new cascading concept... never thought id need more then 32 channels at once, but anyway.
These will be setup in the control-room together, in the same rack, so I was hoping it would be an easy connection to sync the 2... and it seems to be easy enough from your modification.
While I have been using the iPad access from time to time when sitting in a different area of the control room (not directly in from of the UC in the chair, but maybe on the control room couch, etc), not as often as the folks recording would use QMix for changing their own headphone mix...
But if Im reading this correctly, until the AVB switch arrives, I can make the UC changes on any of the new 16 channels as well, 48 total, I will have access to, they will hear those extra channels... and when the AVB switch arrives, they can use QMix again so I don't have to worry about changing their headphone monitor mix.

Thinking this ”outloud” before taking the original RM32AI out of the rack to make room for both to soon be cascaded RMs, hauling out cables to rewire things, incorrectly 4 times, ha....
Going by your photo above, if the RM32AI has its network cable going directly to the RM16AI (vs going directly to the router), it would make sense to set the networking section in UC Surface to “Static Self Assigned” with a 169.254 IP, vs “dynamic” with a 192.168 IP, as dynamic would be getting the ip from the router.
Yeah or do I need more coffee?

As far as I know the mixers are able to assign the addresses they need (as long as nothing else is involved), but my knowledge is ending at this point and I can't help further. I do remember some manual or video about this, but don't ask me what and where and why and whatever...

You might have noticed that a lot of specialists for the AI rack mixers have left here and most of them went to a Facebook group, which I would recommend to join. I am sure you will get all answers there.

I guess I was trying without the avb switch, going by the diagrams. After a dozen or so wire ups, finally decided that using the avb switch would be the best bet. Ordered a Motu avb 5 port switch this morning, (Tues), will arrive Fri morn. All problems will be resolved.
On a side note, I'm a member of that facebook group. Lots of great people. I have learned a lot that I wasn't aware of, and have even had the chance to help others.
