splitting pre-out

recently acquired an old bryston 2B. any caveats about splitting the 970 front L&R and running fronts with the bryston and using the split front thru my 7075 to speakers in another room? the rest of the 7075 channels continue to run with the bryston powered fronts.

You'll need to re-calibrate your system, as the splitter will create a roughly 3dB drop in signal.

thanks, about what i figured.
