I am experiencing a low frequency hum when listening to the radio stations located in the musicroom. I am using the audio output RCA jacks to my house audio system. The hum is also present when listening through the TV via the HDMI connection. The hum only seems to be on the radio stations. Any suggestions?
Solved! Go to Solution.
That is very odd. Mine seem fine (HDMI). Normally if it was every sound had the ground hum present, you'd think it was a physical connection issue. In this case I'm not sure. There aren't any audio settings I know of specifically related to the radio audio quality. Do you have more than one Optik box? If yes, do all boxes have the issue?
Hey Nighthawk, thanks for taking the time to reply.
Yes, I was concerned about the actual audio connections that is why I made sure to try on HDMI as well. Not only am I experiencing the hum, also, some of the radio stations have poor sound quality almost like traditional poor radio air reception. For instance, channel 7072 is clear and the hum is present and channel 7022 is less clear (like poor reception) and the hum less audible. I checked all three optik boxes and the results are the same. I think my next step will be to hook up a ground wire to one of the boxes to check if that may eliminate the hum.
Just a couple of thoughts:
NFtoBC Hello and thanks for responding.
The ethernet cables are the ones supplied by Telus and I do not know the level of quality.
I have not heard of a ferrite choke simply based on my limited technical knowledge. I am assuming the ferrite choke goes on the coax cable?
Yes the choke goes on the cable. You can find them at The Source, and similar places. It is made of the same materials as a magnet, and can cut out AC hum.
