Backed by a limited lifetime
significant volume output of the Black Widow compared to our
main line of headphones requires us to warn the consumer of
potential eardrum damage if detector signal is not regulated
to tolerant levels. Without the limiting circuit engaged, we
recommend starting with a minimal headphone volume control setting
with detector volume at maximum, then gradually increase headphone
volume controls as needed and tolerated.
