Quick Start with Level Magic
For the first use of the Level Magic™ unit it's advisable to start with one of the
factory presets (6 available). Some individually needed changes in the settings
can be saved later in one of the 4 user presets.
- Select the preset meeting the application you are looking for mostly.
- Check if operating level and peak level are meeting your standard. If this is
not the case readjust them and save your settings in one of the available user
presets.
- If after having worked with different presets you think the desired setting is
between two factory presets, compare them in the following table and look for
the differences.
Always take in mind that the balance of both levelling processes is determined
the audio performance of the box mostly! As more available maximum gain by
the transient processor as more boosting the level control is. As less available
maximum gain by the transient processor as more sensible the level control will
be applied.
Because of the use of adaptive controlled processing algorithms and considering the
fact, that the AGC setting must meet the slow gain change requirement, just a few
variations are left. Mostly changeable parameters to play with are Transient
Processor Range in accordance with Transient Processor Program. The
recommendation is:

Level Magic™ is creating the level headroom between the operating level and
the peak level. For almost any audio material used for broadcast transmission
the headroom should be 6...9dB.
With this rule it should be easy to find the settings for the limiter. Even if the operating
level is –20dBFS and therefore a technical headroom of 20dB is available it doesn't
make sense to use it. More than 10dB headroom are increasing the dynamic range of
the audio material for broadcast transmission too much.
