Hello everybody,

I'm thinking of buying a SL Console for a while now for our rehearsal space where we have 3 bands. One thing I don't have a grip on yet without any hands on experience is the audio routing capabilities of the SL series - the manual and guides don't give me an exact picture there (may be my intellectual challenge tho ;) ).

However my dream scenario would be having a little SL with 16 inputs at the PA/Recording rack and either a 32R connected in stagebox mode or stageboxes connected via AVB for a total of at least 48 input channels for the several band scenarios.

My question would be: when creating scenes for Band A/B/C, can I freely choose between any Input on the AVB network channels or do I always have to choose blocks of 8 channels from any stagebox for AVB inputs as long as I do not get over the 32 recording channels.

Thanks in advance for your input and best regards!

Answering the title of your post: both.

The AVB network stream allocation is in banks of 8. It’s the initial network wide housekeeping to allocate AVB channels to the network units you want to receive input from.

The patching of those network channels to mixer channels is a mixer’s local business and is channel by channel.

With the mixer outputs it’s similar. Stage boxes ‘listen’ in banks of 8 AVB streams. But what’s in those streams is up to the mixer sending them, channel by channel.

With mixers on both ends you can go completely overboard by mapping one mixer’s analog inputs and mix outputs to random AVB sends and then untangling the whole thing in the mixer on the other end of the AVB cable and vice versa. Not sure if you want to go there though ;)

Interesting questions... ;) After the firmware upgrade USB is 64 x 64 now, but when I connect my SL 16 or my 32R with a computer, Capture shows 32 + 1 stereo track and there is no chance to activate more than 34 tracks. There is a routing matrice missing, like the one Studio One has. I can't "tell" Capture that there are 64 USB channels available.

Basically, using two mixers does NOT ADD more channels. It only brings more flexibility to the routing of inputs and outputs. It doesn't matter WHERE the input of channel 32 is. The signal can come from console 1 or rack mixer 2 or stagebox 3. It is more important to consider the channel "frame" you are dealing with. Series III is now three types of mixers: a 64 channel mixer(SL 64S), the 32 channel mixers (SL 16, SL 24, SL 32, SL 32S, SL 32SX, SL 32SC) and a 16 channel mixer (16R). You can see it in Capture, which mixer "frame" you are dealing with. Only the SL 64S allows Capture to record up to 64 tracks.

32 tracks should be enough for a band, or even three bands. You would not want to divide 48 tracks in to 16 tracks for band 1, another 16 tracks for band 2 and 16 more tracks for band 3. This makes no sense. Using the same tracks/channels for the same purpose is a better workflow.

AVB has to do with network, USB with recording. The routing/patching is completely separated.

SL 16 and 32R is a perfect combination. You only need one CAT5E cable to connect console and rack mixer (stagebox). Add a router if you want to use remote control.

SL16 | 32R | 16M

Apple routers | iPads | PreSonus SW5E & Motu AVB switches | Alesis iO Dock with AudioTools' Smaart RTA & Spectograph extension |
Yamaha S112, S15e, S10e, SM12, SM10 | Galaxy Audio Hot Spots | Mac mini | Lenovo Laptop | Studio One Pro 3.5.6

Hi everyone,

first of all: thanks for the helpful answers! :thumbup:
So this is more or less my "wish coming true" - perfect.

Yea we got a bit of a crazy situation at our space. 3 Bands with overlapping constellations, and I hate to start rehearsals by having to replug- and rewire stuff all over the place - because I got the role of "tech and sound guy".

We have 2 more classical rock bands (2-3 vox, 2x gtr, bas, dr, bits of keys or e-drums once in a while) and a crazy experimental electro-rock-whatever ensemble with insane amounts of stuff using equipment of all of the above.

My idea was plugging everything in and for the "normal rehearsals" or recording sessions creating a scene with a fully mic'ed drumset (8 mics), vox and other instruments and for the electro-stuff just the basic drum setup for both sets (oh, bd, sn) and the rest of the available channels for all the insanity without ever needing to re-wire anything...

So next step: asking the government (read: wife) for budget. :mrgreen:

Best regards

As Wahler mentioned: the 48 channel requirement needs some thinking. On the AVB network there’s room for 64 channels but the SL16/SL32SC can handle only 32 channels (or 38 when you count the aux and tape inputs too) for mixing. With a second mixer on the network you may be able to do some submixing for the main mixer but it won’t be the same as a full 48 channel mixer. The only PreSonus Series III mixer capable of being that is the SL64S with its 64 channels.
