An earlier post on a similar topic has advice:

BHK250 - RCA & XLR inputs connected at same time?

Hi, just wondering if I can connect the RCA & XLR inputs on my BHK250 at the same time? I want to run my home theatre setup via RCA and my 2ch setup via XLR. Obviously not intending on running them simultaneously but being able to connect them up at the same time rather than connecting / disconnecting when switching from HT to 2ch will be useful in my setup. Just hoping it’s possible and won’t risk any damage to the amp. Thanks.
