Limiters 

Peak Limiter  

The Subwoofer, Midbass and Tweeter channels have individual Peak Limiters designed to pro-
tect each driver from high amplitude, short duration audio input signal spikes that might cause 
damage due to over excursion of the voice coil.   These limiters are implemented digitally with-
in the DSP in such a manner that they have zero effect on the audio signal below their thresh-
olds.   The front LED indicator light will flash RED when a Peak Limiter on any of the driver 
channels is triggered.   The duration of such events is only a fraction of a second.   Therefore, 
the LED flash may appear pink or orange as the eye naturally blends the normally aqua-blue 
color of the LED with the red.    

RMS Limiter 

The Subwoofer, Midbass and Tweeter channels have individual RMS Limiters designed to pro-
tect each driver from long duration, high amplitude audio input signals that might cause ther-
mal damage due to the voice coil.   These limiters are implemented digitally within the DSP in 
such a manner that they have zero effect on the audio signal below their thresholds.   The front 
LED indicator light will flash RED when a RMS Limiter on any of the driver channels is triggered.   

Caution:  

Signals large enough to trigger any of the limiters can generate very high sound 

pressure levels that may result in permanent hearing damage.    

Over Current 

In the event of a large audio input signal that might damage the amplifiers or power supply due 
to current overload,  the power supply is designed to enter into Over Current protect mode.   
This state typically results from a large, broadband input signal burst that flat lines the limiters 
on all four channels simultaneously.   While the fault persists the amplifier power rails shut 
down, the speaker goes quiet, and the front panel  LED turns red.   Once the audio input signal 
is turned down the speaker should reboot within a few seconds.   If the speaker fails to reboot 
or the LED light goes out completely, disconnect the audio input cable and power cycle the 
speaker.   Verify the signal level is attenuated before reconnecting audio input cable.    

Caution:  

Signals that cause Over Current protection to trigger can generate very high sound 

pressure levels that may result in permanent hearing damage.
