Smart Protect

There are advanced DSP protection mechanisms 

designed into the DLM12S to safeguard the subwoofers 
and amplifiers from inadvertent damage.

The protection circuits are designed to  
protect the subwoofers under reasonable   
and sensible conditions. Should you choose 

 

to ignore the warning signs [e.g. excessive distortion], 
you can still damage the speaker in the DLM12S by 
overdriving it past the point of amplifier clipping.    
Such damage is beyond the scope of the warranty.

Limiting

The driver has its own compression circuit which 

helps protect it from damaging transient peaks.    
The compressor is designed to be transparent and 

 

is not noticeable under normal operating conditions. 
The front LED will pulse when in limit. Turn the  
volume down!

Overexcursion Protection

A 36 dB/octave high-pass filter at 32 Hz just prior  

to the low-frequency amplifier prevents very low    
frequencies from being amplified. Excessive 

 

low-frequency energy below 29 Hz can damage the 
woofer by causing it to “bottom out,” also know as  
overexcursion, which is equivalent to a mechanical  
form of clipping.

Thermal Protection

All amplifiers produce heat. The DLM12S is designed 

to be efficient both electrically and thermally.

The amplifier module has internal heatsinks and 

a digitally controlled variable speed fan. As the DSP  
recognizes varying internal heat levels, it will turn   
on at an appropriate speed to draw cool air in over 

 

the amplifier and exit via the side vents.

In the unlikely event of the amplifier overheating,  

a built-in thermal switch will activate, muting the  
signal and ramping the fan up to top speed. An error 
message will also appear on the OLED Display.

When the amplifier has cooled down to a safe  

operating temperature, the thermal switch resets itself, 
and the DLM12S subwoofer resumes normal operation.

If the thermal switch activates, try turning down the 

level control a notch or two on the mixing console (or 
the back of the subwoofer) to avoid overheating the 
amplifier. Be aware that direct sunlight and/or hot stage 
lights may be the culprit of an amplifier overheating.

FYI

The FYI screen displays the latest UI version, DSP 

version, Amp B+ [voltage] and current temperature. 
Nothing may be changed or updated here, just an FYI,  
as stated. This screen is displayed when pressing the 
VOL [10] and MEM buttons [14] simultaneously.

AC Power

Be sure the DLM12S subwoofer is plugged into an  

outlet that is able to supply the correct voltage specified 
for your model. It will continue to operate at lower   
voltages, but will not reach full power.

Be sure the electrical service can supply enough  

amperage for all the components connected to it.

We recommend that a stiff (robust) supply of AC 

power be used because the amplifiers place high    
current demands on the AC line. The more power that is 
available on the line, the louder the speakers will play 
and the more peak output power will be available for a 
cleaner, punchier bass. A suspected problem of “poor 
bass performance” is often caused by a weak AC supply 
to the amplifiers.

Be aware of any error messages that may be displayed 

on the OLED Display. Overvoltage, for example.

Never remove the ground pin on the power 
cord or any other component of the DLM12S 
subwoofer. This is very dangerous.
