My studio monitors: alesis elevate 5 mkii. As you can see by their specs, they have 2x rca and 2x 1/4 line inputs. But both pairs are parte of same input module, so i guess it would be harmful (correct me if im wrong) to have two sources connected at the same time and both of them powered on. But what if i have an audio interface powered off connected to rca ins and my mixer to the 1/4s powered on or vice versa? Basically i would love to be able to have them both hooked up to the monitors to able to use one if them without switching cables. Any hint?
You should consider a "Studio Monitor Controller" with the appropriate number of input (stereo-)channels, and appropriate amount of output (stereo-)channels for your specific requirements.
Connecting both my mixers and my audio interface to my studio monitors
This title of your question indicates 3 input (stereo-)channel/sources
two sources connected at the same time
This statement in the text of your question indicates 2 input (stereo-)channel/sources.
There are various models available, for all kinds of budgets:
- Example of a 4 input device for an affordable budget: Behringer Control2USB
- Example of an 8 input device for a larger budget: Antelope Satori
The usage of a "Studio Monitor Controller" would be the preferred way of connection multiple sources to Studio Monitor speakers.
