Humming sound
I've tried using my Hilton AC-201 and it gives me a Hum while recording. This 201 has always had a hum in it since I bought it.
To minimize hum:
- Use shielded cables.
- Try not to place the recording cable over or near a power cord.
- Try different jacks on your computer. E.g., you could be going into the microphone input instead of the line input -- this could overload the system and create a hum.
If the above suggestions fail to resolve the problem, try using the 'noise reduction' feature of CoolEdit2000 to remove the hum.
