Galaxy Audio DS-EQ230 - Manual (Page 22)

The DS-EQ230 allows the user to select either Bell or Shelving Parameters and assign them
independently using the 30 available filters.
In order to select the filter’s type, it is necessary to have the filter’s GAIN=0.0dB, then using the
“PM2” encoder, rotate it “clockwise” in order to decide the Bell filter’s Bandwidth, or
“counter-clockwise” to select the Shelving filter type (Low or High) and its order (1st or 2nd ).
So, in order to define the filter type for the filter number 1 (“x”=1), it is necessary from the above
Screen, to enter the filter's editing page pressing the ENTER button, and the screen has to appear
as follows:
In this case, the filter’s GAIN=0.0dB, and being BW=1.05, the current filter selected is a Bell type.
Now, rotating the “PM2” encoder clockwise, the parameter BW will range from 0.05 up to 3 for
identifying a bandwidth value for a Bell filter.
If a Bell filter is selected, then the Gain can be modified from 0.0dB and the BW will range
between 0.05 and 3.
If the user wants to select a Shelving filter from the above setting, with the GAIN=0.0dB [if the
GAIN is not 0.0dB, it is necessary to set it at 0.0dB using the “PM3” encoder], rotate the “PM2”
Counter-clockwise. Once BW reaches the 0.05 value, at the next step of the “PM2”
counter-clockwise rotation, the selection of the Shelving filters will be entered.
Still rotating the “PM2” counter-clockwise, the Shelving filters and their order will be selectable in
the following sequence:
1. 1st Order Low Shelving = -6LoSh [on the screen]
2. 2nd Order Low Shelving = -12LoSh [on the screen]
3. 1st Order High Shelving = -6HiSh [on the screen]
4. 2nd Order High Shelving = -12HiSh [on the screen]
Once the desired Shelving filter is selected, the “PM3” can then be used to select the desired GAIN
and when the GAIN is set at a value different from 0.0dB, then the filter type cannot be changed
until this GAIN is returned to 0.0dB.

BELL Filter: As an example, if we want to set a bell filter within EQ-1, then the BW has to be set
At a desired value of say 1.00 using the “PM2” encoder, the GAIN at say +3dB using the “PM3”
encoder and the center Frequency at say 1.00KHz with the “NAV/PM1” encoder.
The EQ sub-menu screen will show the following:
