Are there any special procedures for adjusting the levels or threshold during an event? 

When adjusting the threshold or input gain during an event there will be a time lag before realising 

the full result of the adjustment.  This is because the LEVELIZA works on average data over 

significant periods, especially when the assertiveness is set low for normal operation.  For this 

reason you should temporarily turn the assertiveness to "high (calibration)" whilst carrying out 

adjustments as then the results can be fully assessed within only a few seconds, then once you are 

happy with the new levels and threshold the assertiveness should be turned down again for normal 

operation. 

 

What if the DJs produce a level below the threshold? 

In that case the unit will stop attenuating and the level at the event will become reduced 

accordingly.  In cases where this reduced level is unacceptable and a consistent level is required, 

even if the DJ plays below threshold, then the LEVELIZA should be set so that it is attenuating more 

heavily and therefore the DJs can reduce the signal more before the LEVELIZA stops attenuating. 

This can be achieved during the setup above by setting the input gain knobs back to perhaps 1 or 2 

o'clock in step one, instead of all the way up.  Then, in between step 2 and 3 turn the input gains all 

the way up.  The LEVELIZA should quickly correct this additional level with some additional 

attenuation. 

 

What if the LEVELIZA is attenuating a lot, maybe 10 or more db? 

The sound quality and performance of the LEVELIZA is not affected by the amount it is attenuating.  

If the event is sounding good it doesn't make any difference if the LEVELIZA is working at 3 or 5db of 

attenuation or at 20db.  The only significance of a high attenuation is that the DJs would need to 

then reduce their levels a lot more before the event became quieter, and depending on the 

requirements of the event this might be either a good or a bad thing.
