PEAK LED
The PEAK LED is used to monitor any peaks within the m502. It turns green at -15dBu and red at
+20dBu. The m502βs internal headroom is +26dBu, so occasional red is ξne, just a warning that you are
6dB away from clipping. If the light is mostly red, then you are probably clipping the unit and all your
gear downstream.
