Is it OK to have xlr and rca connected at same time on arc ds450?


I have an arc ds450 amp and would like to have both xlr and rca inputs connected at same time (each from different pre amps). I would not use them at the same time of course. I would use the switch on the back of the amp to switch between the two inputs. Would this be suitable, and not damage anything? Thanks in advance

That's a shame- I was really hoping that I wouldn't have to connect and disconnect cables each time. These high end items don't take well to any sort of wear and tear...
Thanks for your advice!

that's a fair point you make about the xlr's being durable. i'll just have to be careful (as always) when plugging/unplugging the inputs each time. Maybe steering clear of heavy, rigid interconnects that put strain on the terminals is also worth doing.
