I just purchased and installed my first studio monitors and connected them to my audio interface. I had to buy separate RCA(f)–1/4”(m) adapters, since the cable included with my monitors is RCA-to-3.5 mm and my interface has 1/4” outputs.
Every now and again (anywhere from ten minutes to half an hour apart), my studio monitors will emit a loud pop, regardless of what audio is playing or what application is running. The sound is jarring enough to distract and irritate, so I want it gone. The audio itself is fine otherwise – good quality and clarity, no persistent clicking, etc. I’ve already tried some obvious things, such as ensuring the cables are properly plugged in, jiggling them to see whether one might have a faulty connection, playing with the various volume dials and internal settings, etc. That said, I’m new and untrained in audio equipment, so I don’t really know what I’m doing.
Before I bought the aforementioned RCA–1/4” adapters, I had plugged the monitors the other way around, with the two RCA cable ends into the monitors and the 3.5 mm end into the audio interface’s “Phones” output via a 1/4” adapter. The audio quality seemed decent, and I never noticed any popping for the roughly 24 hours it remained connected that way. (Secondary question: If I cannot fix the pops, is there anything wrong with this particular setup, or would it be acceptable for recording/mixing?)
This is a new problem that never occurred prior to the current setup. Nothing has changed in the computer settings or in how the audio interface is connected to the PC.
