Bestes Preisleistungsverhältnis für die Menge an analogen Outputs
Anonymous 10.03.2017
We have screened all available multichannel audio interfaces for the best price per output channel (43 ¤ per channel). We were very lucky that it did turn out to be a MOTU ?

We use the device for multichannel 3D audio loudspeaker setups in combination with the MNTN 3D audio software. For this purpose, it's still not easy to find interfaces with enough output channels for a reasonable price.

For the audio quality, it's MOTU as we know it. No concerns for all the critical aspects. A minor thing is that it's hard to get started without taking a quick look at the manual. That's why we spend only four stars on usability. However, that's how we know MOTU devices, too. But still, it's almost plug-and-play.

A big plus is the possibility to combine up to 5 devices to end up with 120 output channels (=loudspeakers) from one single computer. The scalability not only counts for practical purposes, but also for the budget.

A minus: The ads on the MOTU product website did let us understand that the device could be connected to a Mac directly via ethernet cable. Until now, we couldn't figure out how that might work. However, USB works fine or course.

Here is an article comparing other multichannel audio interfaces to connect a bunch of loudspeakers to you computer:

This rare item was delivered with ease. I have been looking for this for a while. I’m coming to the conclusion that Thomann is my go to store.

erreurs de conception
Frederic6273 29.03.2015
j'ai acquis la pire 24 AO AI dans le but d'avoir 64 Io

tout d'abord on découvre qu'au final on ne peux router sur usb que 24 sur 64... moyen.. en gros les 24 in/out analogiques.. c'est domage car il y a 3x2 set de ports ADATS en plus !! donc 48 in/out en plus

firmare truffé de bugs, perte de la cnx à l'admin du truc lorsque connecté en USB.. finalement aprés 3 firemare update en 2 mois bonnes nouvelles

64 in/out routable sur usb au final, enfin

plus de perte de connexion aux cartes...

par contre gros défaut de conception, les in/out ne marchent pas sous mac (pas testé sur d'autres os) en effet si l'on met en 1ere la 24Ai les 64 1ere input sont numérotés 1 a 64, comme la 24 AO arrive derriere, les sorties correspondantes par exemple au 24 Input analog sont numérotées de 65 a 87 !! impossible d'utiliser de mémoire, a chaque fois que l'on plug un effet pour l'utiliser en bloucle, il faut aller à la peche sous xls pour connaitre les in/out a utiliser !!
pareil sur les adats, rien ne martche et le support motu s'en moque totallement, ce produit n'a pas du tout été fait pour être utilisé comme le fait à savoir uniquement les in/out mais en standalone, en mixant tout dans leur soft, qui à l'air bien au deumeurant

Parfait pour une installation fixe.

Utilisée en studio avec une 24AI, elles sont parfaites et d'une stabilité à toute épreuve.
Les deux sont simplement reliées entre elles avec un câble ethernet, et sont configurées pour apparaître comme une seule et même interface audio.
Les réglages peuvent être protégés par mot d passe, ce qui est très utile dans mon cas (studio son dans une école).
