Level Magic™ Dynamic Audio Leveling
Audio leveling is also supported by the FLEX decoding module. This feature defines a
constant gain adjustment for incoming audio signal.
Dynamic leveling uses the same technology found in Jünger Audio's Level Magic™ hardware-
based processors. Level Magic is a trademark of Jünger Audio Studiotechnik GmbH. The
dynamic leveling option requires a firmware license.
