LevelMax™ Suite Limiters
This is a suite consisting of a peak voltage limiter, rms power limiter, clip limiter, and transducer thermal limiter. The Limiter panels can be accessed by clicking one of the
amplifier channel's
Limit
icons from the Configuration panel (see
Figure 43:
LevelMAX panel
On Button
This button turns the LevelMax limiters on or off.
Threshold (Peak and RMS)
These parameters set the level, in absolute voltage, which the peak and rms limiters will allow from the amplifier. Note that the Advanced option must be selected to adjust
the Peak Threshold parameter manually.
Release (Peak and RMS)
These parameters set the release time of the peak and rms limiters. The release time is defined as the time it takes each limiter to increase the output signal by 20 dB. Note
that the Advanced option must be selected to adjust these parameters manually.
Transducer Thermal Limiting (Thermal Voltage and Thermal Response Time)
The transducer thermal limiter limits the long-term output power of the amplifier to what the loudspeaker load can handle without overheating and going into thermal
compression. You can set the voltage level at which the thermal limiter engages and the thermal response time. Your loudspeaker manufacturer might be able to provide this
information.
Automatic
With this option selected, the software determines the best settings based on the signal characteristics. You can still modify the ` Threshold, Transducer Thermal Voltage,
and Transducer Thermal Response Time parameters, but all other parameters will be set automatically.
Advanced
WIth this option selected, you can modify all parameters available in the Limiter panel.
Amp Output Meter
This meter shows peak and rms output levels in dBFS.
Gain Reduction Meters
These meters show the peak, rms, and total gain reduction levels incurred by limiting.
