Audible or very high floor noise (also referred as "pink" noise, "background" noise, or "hiss") happens on the IRH-280/281 headsets.
Audible noises can happen for a few reasons. Most commonly, unshielded signal wires are the main cause of unwanted noise. Additionally, signal wires to close to power lines, DC, or AC can also cause the issue. It is advised to keep them a part always.
Solution | Workaround
- Run programming with HI and VI-N audio.
- Set the compression slope to 2:1.
- Adjust the appropriate DIP switches and input level controls to cause the audio level LEDs to flash during normal programming, but not stay lit continuously.
- Try listening to each channel on IR headphones.
- If necessary, adjust compression to bring up low levels or reduce noise.
