• Menu “LIN/RIN” Equalizer’s Channels Editing [access by pushing the “LIN/RIN” buttons] From the “Default Screen”, it is possible to access the “LIN/RIN” editing menu by pushing the “LIN” or “RIN” button. Once the button is pressed, the related blue “EDIT” LED will turn ON. The Sub-Menu pages can now be scrolled through by rotating clockwise and counter-clockwise the “NAV/PM1” encoder. For parameter editing, it is necessary to press ENTER and an arrow will appear on the left of the screen “->”.
Source page - from this page it is possible to assign one of the following Inputs to any Equalizer’s Channel: 1. Analog InA = Input Channel A 2. Analog InB = Input Channel B 3. Analog InA+B = Sum of Input Channel A and Input Channel B 4. Digital Left = Input S/PDIF Channel Left 5. Digital Right = Input S/PDIF Channel Right 6.
Delay page - from this page it is possible to set the Equalizer’s Channels Delay Time from 000.000mS up to 848.9984mS, by steps of 1mS or 20.8uS. To set the Delay time press ENTER an arrow will appear on the left of the screen “->”. Then use the “PM2” encoder to set the Delay Time in steps of 1mS and the “PM3”, for setting the “fine” Delay Time in steps of 20.8 microseconds. The following is an example screen for the “Delay” page where the Delay Time of Equalizer’s Channel A (named Left) is set to 160.
LPF sub-menu - from this sub-menu it is possible to set the Equalizer’s Channels Low Pass Filter (LPF). The following is an example of a LPF sub-menu screen with the filter set at 24dB Linkwitz/Riley on Equalizer’s Channel A (named Left): OutputADPA-240A Left LPF -> 20.0Hz 1x2 WAYLnk/Ril X-OVER24dB The filter’s parameters can be modified by use the “PM2” and “PM3” encoders for editing the Filter's High Cut Frequency and the Filter’s Type and Order.
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 ).
Once in the Bell Filter’s edit screen all the filter's parameters can be modified using the “NAV/PM1”, “PM2” and “PM3” encoders for editing the Filter’s Center Frequency, Bandwidth BW and Gain. The Center Frequency of the Parametric Filter can be edited using the "NAV/PM1" encoder, the BW the "PM2" encoder and the Gain the "PM3" encoder: “Center Frequency”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24 of an Octave and can be adjusted by rotating the “NAV/PM1” encoder.
Note: Once the desired High 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. Once in the High Shelving Filter’s edit screen all the filter’s parameters can be modified using the “NAV/PM1”, “PM2” and “PM3” encoders for editing the Filter’s Low Cut Frequency, Filter’s Order and Gain.

Once pressed, the related blue “EDIT” LED will turn ON. The Sub-Menus pages can now be scrolled through by rotating clockwise and counter-clockwise the “NAV/PM1” encoder. For parameter editing it is necessary to press ENTER and an arrow will appear on the left of the screen “->”.
• MENU “A and B Output Channels Utilities” [Access by pushing the “LOUT/ROUT” buttons] From the “Default Screen”, it is possible to access the “Equalizer’s Channel Utilities” menu by pressing the “LOUT” or “ROUT” button. Once pressed, the related blue “EDIT” LED will turn ON. The Sub-Menus pages can now be scrolled through by rotating clockwise and counter-clockwise the “NAV/PM1” encoder. The available utilities are the following: 1.Flat Equalizer 2.Copy Equalizer from Ch[x] 3.
• Factory Reset In the event of the password being lost or any other reason, the user may require the unit to be Reset to the original factory settings. A “Factory Reset” that will clear all settings of the DS-EQ230 and return the device to the original factory setting, is available to the user. Note: Continuing with this process will mean the DS-EQ230 will re-initialize to the original factory settings and any previously stored information and changed parameters will be permanently lost.
• Equalizer’s Channels LIN/RIN and Compressor/Limiter’s Channels LCOMP/RCOMP Last Edited Parameter Return Function Once you have escaped out of parameter editing within the individual Equalizer’s Channel or Compressor’s Channel the DS-EQ230 will remember this last editing action on that Channel. When you return for your next editing action pressing the EDIT button on that channel will immediately return you to the screen related to this last editing action.
