• Encoders and ENTER, ESC buttons
The DS-SP36 is equipped with 3 Relative Encoders, “NAV/PM1”, “PM2” and “PM3”. These encoders allow
you to navigate the user interface and edit sections of the processor. They allow the user to navigate within
the screen for the selection of sub-menus, pages and parameters and to select the values to be assigned
during the editing operations.
The “ENTER” and “ESC” buttons allow the user to confirm or NOT confirm the operations performed by the
encoders.
• UTILITY, A/B/C and 1/2/3/4/5/6 buttons
The UTILITY button allows the User to enter the Sub-menus and set the general characteristics of the
Processor. The A, B and C buttons allow the User to enter the Editing Menus of the Processor's Input
Channels and buttons 1, 2, 3, 4, 5 and 6, allow the User to enter the Editing Menus of the Processor's
Output Channels.
The A, B and C buttons as well as the 1, 2, 3, 4, 5 and 6 buttons have double functions dependent on the
push and hold time.
When the A, B and C buttons are pushed and held for more than one second Input Channels A, B or C are
either muted or unmuted. The red LED will illuminate when the Channel is MUTED. When the “MUTE” LED
is OFF, then the related Input Channel is UN-MUTED.
A momentary push of the A, B and C buttons enters the Editing Mode for the Input Channels (see later for
the Input Channel Editing details). The blue “EDIT” LED will now be ON.
When the 1, 2, 3, 4, 5 and 6 buttons are pushed and held for more than one second the Output Channels 1,
2, 3, 4, 5 and 6 are either muted or unmuted. The red LED will illuminate when the Channel is muted. When
the “MUTE” LED is OFF, then the related Output Channel is UN-MUTED.
A momentary push of the 1, 2, 3, 4, 5 and 6 buttons enters the Editing Menu for the Output Channels (see
later for the Output Channel Editing details). The blue “EDIT” LED will now be ON.

● Menu “Input A/B/C” Input Channels Editing [access by pushing the “A/B/C”
buttons]
From the “Default Screen”, it is possible to access the “Input A/B/C” menu by pushing the “A” or “B” or “C”
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
“ -> ”. Then use the “PM2” and “PM3” encoders for selecting and setting the parameter values. On some
parameters that have three independent values, you will also need to use the PM1 encoder, eg filter
parameter settings.
Note: All parameter editing can be done using the “NAV/PM1”, “PM2”, and “PM3” encoders and the current
shown value of the selected option is AUTOMATICALLY loaded during the encoders’ use and stored as the
current value once leaving the page is AUTOMATICALLY loaded during the encoders' use and stored as
current value once the page is left.
Gain page – from this screen it is possible to set the Input Channels Level from -12dB to +6dB. Press
ENTER, and an arrow will appear on the left of the screen “ -> ” then use the “PM1” or “PM2” buttons.
The value set on this screen will only affect the input level of the selected Channel A, B or C.
The following is an example screen for the “Gain” page that has set the Gain of Input Channel A to +0.0dB:
Delay page – from this page it is possible to set the Input Channels Delay Time from 000.0000mS up to
848.9984mS, by steps of 1mS or 20.8uS.
To set the Delay time, press ENTER, and 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 Input Channel A is set to
160.1872mS:
Input-A Gain
–› Gain = + 0.0dB
Input-A Delay
–› Gain = 160.1872mS

17
EQ: [x] sub-menu – from this sub-menu it is possible to set the Input Channels five available Parametric or
Shelving Filters.
The DS-SP36 allows the user to select either Bell or Shelving Parameters and assign them independently
using the 5 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 select 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 will appear as follows:
In this case, the filter's GAIN=0.0dB, and 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, with 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.
Input-A EQ-X
1.00KHz BW1.05 0.0dB
Input-A EQ-1
–› 1.00KHz BW1.05 0.0dB

18
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:
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.
“Bandwidth BW”: the selectable BW range is from 0.05 Octave to 3 Octave in steps of 0.05 Octave and
can be adjusted by rotating the “PM2” encoder.
“Gain”: the selectable Gain range is from -15dB to +15dB in steps of 0.5 dB and can be adjusted by
rotating the “PM3” encoder.
Low Shelving Filter: As an example, if we want to set a low shelving filter within EQ-1, then the PM2
encoder has to be rotated counter-clockwise until the desired Low Shelving filter, say -6LoSh appears on
the screen, the GAIN at say +3.0dB using the PM3 encoder and the High Cut Frequency at say 1.00KHz
with the NAV/PM1 encoder.
The EQ sub-menu screen will show the following
Note: Once the desired Low 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 Low 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 High Cut Frequency, Filter's Order and Gain.
The Hi Cut Frequency of the Low Shelving Filter can be edited using the “NAV/PM1” encoder, the Filter's
Order can be adjusted by the “PM2” encoder and the Gain the “PM3” encoder:
“Hi Cut 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.
“Low Shelving Order”: the selectable Low Shelving Filter's range can be selected between the 1st
(Lo-1st.) and the 2nd (Lo-2nd.) one.
“Gain”: the selectable range of the Gain is from -15dB to +15dB in steps of 0.5 dB and can be adjusted by
rotating the “PM3” encoder.

High Shelving Filter: As an example if we want to set a high shelving filter within EQ-1 then the PM2
encoder has to be rotated counter-clockwise until the desired High Shelving filter say -6HiSh appears on
the screen, the GAIN at say +3dB using the PM3 encoder and the Low Cut Frequency at say 1.00KHz with
the NAV/PM1 encoder.
The EQ sub-menu screen will show the following
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.
The Lo Cut Frequency of the High Shelving Filter can be edited using the “NAV/PM1” encoder, the Filter's
Order can be adjusted by the “PM2” encoder and the Gain the “PM3” encoder:

Note1 : Once the desired options have been selected using the 3 encoders, they are automatically saved
as current and stored in the DS-SP36 system status once leaving the page.
Note2 : To exit this page, push the “ESC” button.
● Menu “Output 1/2/3/4/5/6” Output Channels Editing [access by pushing the
“1/2/3/4/5/6” buttons]
From the “Default Screen”, it is possible to access the “Output Channel” menu by pressing the “1” or “2”or
“3” or “4” or “5” or “6” 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.
For parameter editing it is necessary to press ENTER and an arrow will appear on the left of the screen
“ -> ”. Then use the “PM2” and “PM3” encoders for selecting and setting the parameter values. On some
parameters that have three independent values, you will also need to use the PM1 encoder, for example for
the filter’s parameter setting.
Note: All parameter editing can be done using the “NAV/PM1”, “PM2”, and “PM3” encoders and the current
shown value of the selected option is AUTOMATICALLY loaded during the encoders’ use and stored as the
current value once leaving the page.
HPF sub-menu – from this sub-menu it is possible to set the Output Channels High Pass Filter (HPF).
The following is an example of a HPF sub-menu screen with the filter set at 24dB Linkwitz/Riley on
Output1... using the name “High” (see later for assigning a Name to the outputs):
