Notch Filt Filter: Filters canceling the band “around” the selected frequency; the amount of
canceled band is decided by the Q value
I
f we selected a Notch Filt filter within EQ-1, then the Q has to be set at a desired value of say
1.00 using the Param.3 encoder and the Notch Frequency at say 1.00KHz with the NAV/Param.1
encoder; the EQ sub-menu screen will show the following:
Once in the Notch Filt Filter's edit screen, all the filter's parameters can be modified using the
“NAV/Param.1” and “Param.3” encoders for editing the Filter's Notch Frequency and Q:
“Notch Frequency”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1Hz and
can be adjusted by rotating the “NAV/Param.1” encoder.
“Q”: the selectable Q range is from 0.3 up to 20.0 in steps of 0.1 and can be adjusted by rotating
the “Param.3” encoder.
When in the Parameters Editing Page, pushing once more the ENTER Button, it is possible to
access the page of the Frequency Fast Setting:
Here, the NAV/Param.1” encoder will increment/decrement the Frequency value by step of one
thousand Hz, the Param.2 by steps of one hundred Hz and the Param.3 by steps of one Hz.
Note1: once the desired options have been selected using the 3 encoders, they are automatically
saved as current and stored in the DLM26 system status once leaving the page.
Note2: to exit this page, push the “ESC” button.
Vu-Meter page – from this page it is possible to select what is shown on the Output LED meters,
by using the “Param.2” or “Param.3” encoders.
The outputs' LED meters can show the Output signal LEVEL, the Output RMS Compressor's activity
or the Output Peak Limiters' activity.
When the Output signal Level is selected, the LED meters will show, from bottom up, the Level of
the signal:
When the RMS Compressor's activity is selected, the LED meters will show, from top down, the
activity of the RMS Compressor Limiter on the output
When the Peak Limiter's activity is selected, the LED meters will show, from top down, the activity
of the Peak Limiter on the output
