I need an Audio Detective

Hello AG I have a unique situation with my audio system that I have no answer for. Here’s the deal. I was playing my Magnum Dynalab tuner and noticed my Denafrips Terminator 2 DAC standby light was not on. The power cord had come loose from the back so I snugged it up and the light came on. For whatever reason I hit the on button on the DAC and when I did it crushed the signal on my tuner. I cut DAC off and signal came back. I tried another tuner same result. Any ideas as to what is going on?

Antenna is on the roof. I have 4 tuners with a quick disconnect I have set up so I don’t weaken my signal by having all 4 on a splitter. I only have 1 at a time. I am beginning to believe it is an RF issue being picked up by cabling. I am going to try this with my other 2 tuners tonight to see if the same thing happens

This is one of those situations that will drive many audio-enthusiasts crazy. It really depends on how much work you want to put into this. You could simply keep the DAC off (along with all LED lighting) while listening to your tuners. That would be the easiest solution here.

Or, you could unplug all audio interconnect cables from the DAC (with the unit powered ON), and see if that makes a difference, and report back your findings. It’s very possible you *might* be able to reduce this RFI using ferrite on some of the DAC cables (which ones will need to be determined). One tuner (the Magnum) might be more sensitive to this RFI vs your other tuners.

Hmmm, an audio-enthusiast that still values OTA (over the air) FM listening. I'm impressed.
