Rogue Audio Cronus Question

I'm just getting used to a new(used) Rogue Cronus (not the Magnum) - and I noticed that if I leave the tuner on (Aux 1) while listening to the turntable (Phono), some faint music from the tuner comes out of ONE of the speakers. It's in phono mode, and obviously I can get rid of the sound by simply turning off the tuner, but why would that happen, and how can I correct? Thanks.

My recently sold Sony tuner did not do this through my Modulus 3B and Odyssey amp but both of my Magnum Dynalab tuners FT101A and MD90 do cause creep through. I believe it's because the Tuners output voltage is very high. I have been turning off the tuners for years with no problems.

You can try shorting plugs in the unused inputs. My tuner bleeds over but not when the phono is playing! You can make your own plugs by using some cheap rca type cables,just cut them in half and twist the positive and ground together!

The first thing that I would do is double-check your cable routing. Make sure that the tuner interconnects are well away from the phono interconnects. Phono gets the largest boost in signal strength in a system so any stray noise will get boosted along with it. It's also especially important to keep phono interconnects away from power cables for the same reason.

My Tivoli 2 radio does this. Never knew it was a cross talk circuit thingie, but that makes sense.

As others have said it's called crosstalk and the phono input is most susceptible because of it's high gain (relative to the other inputs which are line-level).

Use short, shielded phono interconnects and route them away from other cables. And just turn OFF your tuner when not in use, no big deal.
