Hi There,

I'm looking for some advice on how to combine / route audio & mic signals through the Korg Radias.. I'm wondering if anyone may have any ideas. I'll try to explain the problem as clearly as possible..

I have a wireless transmitter in one part of the room that transmits audio signals to a powered speaker in another part of the room. This transmitter ONLY has two input jacks for the left and right signal.

The audio signal being transmitted must come from 1 of 2 different sources:
- Music being played by a 2 channel media player that ONLY has balanced output jacks (1/4” TRS which combine Channels 1 & 2), or separate analog audio outputs (left and right RCA) for Channel 1 and another set of analog audio outputs (left and right RCA) for Channel 2, and;
- Robot voices being generated by the rack mountable Korg Radias (without the external keyboard) using a dynamic mic plugged into Input 2 jack on the back of the Korg Radias.

Here’s the challenge… I would like to be able to play music and create robot voices at the same time while the music is playing. Unfortunately, the wireless transmitter only has a left and right input jack, so I’m forced to choose between plugging in the 2 channel media player or the Korg Radias (but I can’t do both at the same time).

I’m wondering if there’s a way that I can plug the 2 channel media player into Input 1 & 2 jacks on the Korg Radias and then simply route the music internally "as-is" over to the output jacks. I’m also wondering if I can somehow plug my dynamic mic into the condenser mic input jack on the Radias, thereby freeing up Input Jacks 1 & 2 for the 2 channel media player. My goal is to simply play the music through the Radias using the input / output jacks, but also add robot voices using a dynamic mic (I would rather not use a condenser mic because I’ve been told I may get a lot of feedback)..

Hope that makes sense!!

Thanks,
Warren

You can't use the condensor input AND audio inputs 1 & 2.

the condensor input is just a different preamp stage and still goes into the input 2 ADC.

Normally if you want to merge multiple audio sources, you use a mixer. They are designed to do precisely this kind of thing - mix two or more audio sources and route to output(s)

Thanks for the feedback.. The dual media player already has a mixer built into it (but only for mixing the internal audio signals from the media player).. It just doesn't have extra plugs to accept external audio signals.. Guess I'll just have to upgrade to a better mixer.. Thanks!
