I want to take 2 separate audio signals being fed into a multi and plug them into the Reverb Input (on the Reverb module). I know it's generally forbidden and I don't want to overload the input. But is it safe to do?

Don't see why not. The only way you'd wind up with overvoltage from two inputs is if they were being fed into an adder, where you could get 10V out from two 5V inputs. But with a mixer (of any sort) output, the output never exceeds the hottest input value.

Better using a mixer just to be safe! Mult are not protected...

Turns out they are - to quote Robert in another thread: Basically, you can use the mults as passive mixers as they are; the modules contain an output resistor of 1k mostly, so you get the signals mixed when connected together. No worries, nothing can be damaged by this! As someone who was eyeing more mixers at the expense of fun stuff I'm quite pleased about this! |

Regarding mixers, an idea from a while ago popped up again in my mind: forum.aemodular.com/post/3178/threadAs with VCAs you cannot have enough mixers, so this was my idea to have four 4-input mixers in one module (sacrifying fine control over the levels, but at least some fixed attenuations). |

Thanks for all the responses but there are mixed messages here. So it is safe to put two audio signals into a multi and then then out to a Reverb Unit. Because the multis are buffered? I am confused with the concept of using a mixer to mix 2 audio inputs to then put into an effect as this sounds like pre-amping the signals, which would be worse no? |

I'm no expert but my understanding based on the post I quoted from Robert (I was asking as I wanted to convert some multiples into passive mixers btw - turns out I don't need to as they already are!) is that it's fine. With the rest I'm not quite sure what you mean - the mults are passive so there is no buffering or preamping going on - there will be a drop in so level the more inputs you combine too. |

Soz tIB. I'm not disparaging your input. lukylutte reckoned it was iffy so I'm just trying to get an aggregate of peoples opinions. I feel stupid really because it it requires is for me to just plug them in and see. I just don't want to blow my Reverb module. My thinking is with putting both the audio inputs into a mixer and then into the Reverb module might be overloading the input anyway. I usually only ever use the multis for clock & gate signals.

I've basically taken Roberts advice of: "don't worry, you can't break things", and have done some really crazy things. No damage yet. You're safe imo.

No need to apologise- I thought the same as luckylutte and had been using my mults in the same way as you until I found out the info from Robert above. |

I've just put two outputs from 010Drum and Kick into multi and from there into one channel of the mixer (and then into audio output). I haven't noticed any kind of volume drop. It sounded just the same as through 4ATT/MIX output which I usualy use to combine several soundsources

Thanks folks. I'm re-assured. Going to keep the defibrillator handy just in case.
