I just attempted to use the RCA L & R out from a BHK Pre for LFE inputs into pair of GoldenEar Triton One.R speakers. The XLR output goes to the Amp.
With this configuration I am getting a loud hum from the speakers and no audio. Powering down and removing the cables from the Pre restores audio.
I have read hear on the forum of others successfully using a similar setup.
Thanks in advance,
