RMS Limiter
The primary purpose of the
RMS Limiter
is to protect the speakers from the thermal
damage that can be caused by extended periods of excessive power usage. Any signal
whose RMS level exceeds the threshold will be compressed, thereby reducing the signal.
The
RMS Limiter
uses the RMS (root mean square) level, which is proportional to the
average amount of energy over a short period of time, to determine when a signal has
met the threshold. Because the RMS level is more closely related to the perceived volume
of a signal than the peak level, this type of limiter is less sensitive to extremely short signal
peaks, and more sensitive to the overall volume of a signal. This is opposed to the
Peak
Limiter
, which is triggered by any signal that exceeds the threshold, however briefly.
Tip:
The Presets feature contains predefined Peak Limiter settings for a number of specific speakers.
To adjust the RMS Limiter settings for a channel:
1
On the appliance Web UI’s main page, select
DSP
.
2
Select the
Menu
button for the channel.
3
From the drop-down menu, select
RMS Limiter
