Krell HTS 7.1 pre-amp mode

Is it possible to use both the RCA and XLR analog audio outputs at the same time in pre-amp mode?
There is usually not a switch on the outputs. :)  I've never seen a device with XLR and RCA outputs that didn't power both simultaneously. INPUTS however are often switched.
Thanks erik_squires! You are right, on settings, you can select input, but there are no options for output.
