types of output sockets is not enough for the speaker electronics to process the 
signal effectively.  bhi have another product that will work with these levels of signal, 
the NEIM1031MKII (DSP Noise Eliminating In-line Module). Please contact bhi for 
more information. See end of operating manual for contact information.  
 

Sometimes there is a short delay before the noise cancellation is active:

 

  This is due to the time the DSP takes to start processing the signals. This gives you 

the opportunity to check that the DSP is not taking out any detail from the signal. 

 

Sometimes I can hear a processing sound in the speakers when no signal is 
present: 

  This is caused by the DSP processor and is normal.  When a signal is applied you 

should not be able to hear this in the speaker.
