Ideas sought for RF impedance selection
The &quot;BNC to XLR cables&quot; are basically nonsense. You can't do that. You need to use an audio balun. If the user has unbalanced source and doesn't want to use a balun, then they need to run this unbalanced signal all the way to the chassis, and you need to have both a balanced XLR input and an unbalanced RCA jack, and you can select between those. The problem with &quot;BNC to XLR cables&quot; is that they have no place in any system that is meant to perform well, and it's not your job to accommodate people who purposefully degrade their signals.
