I think i read here that it isnt a good idea to output an external synth audio to the MX 1/8 audio input.

I don’t think you read that anywhere. Of course, you can plugin any audio device with an 1/8 inch stereo mini plug output. Adjust the volume on the external device.

Thanks for the info on this subject.

It was page nine,11th topic down in the MX forum where i read about hooking up external synth into MX 1/8 input.
My wording probably didnt come out right on my initial post,lol.

Again many thanks Bad Mister.
The info was helpfull. 🙂

Adapting an instrument with high level Outputs, say on 1/4” or XLR” jacks down to an 1/8” mini plug is ignoring a certain reality.

If your Synth has an output on 1/8” mini stereo, it’s a good bet you can continue without worries of overloading the input (and that is that only real concern in all of this). It’s when you find yourself adapting down that you have to be careful.

But a device outputting its audio on an 1/8” mini screams consumer levels... just as a Aux In on a synth screams consumer levels. Remember you have no level control protecting that Aux In, so level is controlled at the SOURCE device. Meant for a handheld playback device like a iPod, phone, handheld recorders, etc., etc. Not LINE level signals really...

I just hooked up my MONOTRON to my MX49.
It works really well.
The MX 1/8 input doesnt distort.
I did make sure the MONOTRON volume was low.
The sweet spot seems to be MONOTRON volume at about halfway.
I could have probably turned up the MONOTRON more but the gain is good and loud at about half.
Plus when you turn a MONOTRON volume way up or all the way up it gets a hissy noise.
