Hi, folks,
This is my first post ever here and after some research here in the forum I came to no conclusion, I'd like to beg your pardon if the following topic has been discussed already.
The 4I/O module seems to offer connectivity to the Eurorack universe, and strange enough, it is not an input, not an output, but a combined input/output module with no switches at all.
The description declares that I can connect audio sources to this module, so it will function as an input. But what about the O for output? Can I also route AE Modular signals to these 3,5mm connectors?
Thanks a lot beforehand for every explanation you might offer!
Have a nice time and stay in good health, guys!

The 4I/O offers connectivity, and protection of AE from eurorack. Signals out of AE will keep their voltage. Signals into AE will be flattened when the voltage is too high. You've got the same protected I/O on the master module, except on the master two for cvs and two for audio, while on 4I/O they can all be switched between audio and cv. |

Thanks for the quick response!
I did not quite understand what you said about the master module. I have the revision 3 with two audio connectors and two control connectors. Audio 1 is identical to audio 2, and control 1 identical to control 2, right? Or did you mean revision two of the master module?

Hello syndenfall, each of the sockets in the 4I/O can be either an input or an output and you can select between Audio or CV with the little switch next to each socket. If you want to get CV into the AE system from Eurorack, then you just put the cable into one of the I/O sockets and then an AE patch cable from that port number into whichever other AE module you want to control. If you want to get CV or audio out of the AE, then just connect a cable into one of the 4I/O sockets and connect it to your mixer or maybe a Eurorack effects module. Eurorack signals are much "hotter" than AE signals with voltages between -10 and +10 Volt. AE only works with voltages between 0-5 Volt and the I/O module will cut ignore any negative voltage and "cut off" any voltage above 5 Volt. So you are relatively safe in sending Eurorack signals into the AE, but you may not get the same "range". The Master module as 2 audio and 2 CV sockets and these work exactly like the 4I/O module. I hope this helps, please try it out, you won't hurt your system. You can also find a lot of good documentation for each module in the Wiki: wiki.aemodular.com/pmwiki.php/AeManual/4IO |

yes, the master sockets work exactly like the 4I/O. Unless you want to connect multiple ways with a Eurorack or other similar gear you wouldn't need the 4I/O.

Thanks for the explanation, guys, that helped a lot!
I have begun testing yesterday with the Master module, and everything worked very well, lots of fun   . Now I'm waiting for the 4I/O thingy! |

as others have said, AE will 'clip' inbound audio and cv signals, and output the audio signal is pretty 'low' due to being line-level so, on the eurorack side.... id recommend for audio and 'input/output' module - these don't have to be expensive, I use use various Ladik modules as they are small and (relatively) cheap. eg. ladik.ladik.eu/?page_id=1417 - A-525 2ch line preamp + 2ch line out (4HP) - 40 GBP (I also have the a520 , which provides 4ch preamp - which is very handy) for CV , usually 5v output is 'ok', so mainly it's just input attenuation, which i use regular attenuators for. (interestingly , Ive just noted the above A525 has DC coupled output, so probably could also work?!) you can get by using regular attenuators and VCAs (if they do > 1:1 gain) , but I actually found it so much more fun in eurorack to be able to plug in other gear i have (including AE), and those 4HP make it easier, and so more likely to happen  |
