8Clip LED (MLS 506MA and MLS 506SA only) — This LED flashes when the audio level for a particular input is too high. If the audio level exceeds the point at which the Clip LED flashes, the audio will be clipped, which results in a distorted output. Adjust the output level of the active source or the input level at the switcher (via the front panel LCD Audio Adjust menu or via the control software) so clipping does not occur.
