I have a Shaw Digital Terminal for TV and I use an RF modulator because I have an older TV.
With the Shaw Digital Terminal using RCA cables connected to the modulator, there is a buzz sound in the audio.
With a DVD player using RCA cables connected to the modulator, there isn't a buzz sound in the audio. It's clear.
Why does this happen? Is it a problem with the RCA outputs on the Shaw Digital Terminal?
Thanks.
