• Encoders and ENTER, ESC buttons

The DS-SP24 is equipped w ith 3 Relative Encoders, “NAV/PM1”, “PM2” and “PM3”. These encoders allow you to nav igate the user interface and edit sections of the processor. They al low the user to navigate with in the sc reen for the selection of sub-menus, pages and parameters and t o select the values to be assigned d uring the editing operations.

The “ENTER” and “ESC” buttons al low the user to confirm or NOT confirm the operations performed by the encode rs.

• UTILITY, A/B and 1/2/3/4 buttons

The UTILITY button allows t he User t o enter the Sub-menus and set the general characteristics of the Processor. The A and B buttons allow the User to enter the Editing Menus of the Pr ocess or's Input Channels and butt ons 1, 2, 3 a nd 4, allow the User to enter the Editing Menus of the Processor's Output Channel s.

The A and B bu ttons a s well as the 1, 2, 3 and 4 buttons have double functions dependent on th e push and hold time.

When the A a nd B butt ons are pushed and held for more than one second Input Chann els A or B are either MUTED or UN-MU TED. The re d LED will illuminate when the Channel is MUTED. When the “MUTE” LED is OFF, then the relate d Input Channel is UN-MUTED.

A momentary push of the A and B buttons enters the Editing Mode for the Input Channels (s ee later for the Input Channel Edit ing details). The blue “EDIT” LED will no w be ON.

When the 1, 2, 3 and 4 buttons are pushe d and held for more than one second the Output Channels 1, 2, 3, and 4 are either MUTED or UN-MU TED. The red LED will illuminate when the Channel is MUTED. When the “MUTE” LED is OFF, the n the rel ated Output Channel is UN-MUTED.

A momentary push of the 1, 2, 3 and 4 butto ns enters the Editing Menu for the Output Channels (see later for the Output Channe l Editing details). The blue “EDIT” LED will now be ON.

• DS-SP24 Menu and Sub-Menu Structure s

Gain page – from this screen it is pos sible t o set the Input Channels Level from -12dB to +6dB, press ENTER an arrow will a ppear o n the left of the screen “->” then use the “PM1” or “PM2” buttons. The value set on this screen will on ly affect the input level of the selected Channel A or B. The following is an examp le screen for the “Gain” page that has set the Gain of Input Channel A to +0.0dB:

Delay page – from this page it is poss ible to set the Input Channels Delay Time from 000.0000mS up to 848.9984mS, by steps of 1mS or 2 0.8uS. To set the Delay time press ENTER, an ar row will appear on the left of the screen “-> ” then use the “PM2” encoder to set the Delay Ti me in steps of 1mS and the “PM3” for setting the “fine” Delay Time in steps of 20.8 microseco nds. The following is an examp le screen for the “Delay” page where the Delay Time of Input Channel A is set to 160.1872mS:

EQ: [x] sub-menu – from this sub-m enu it is p ossible to set the Input Channels five available Parametric or Shelvin g Filte rs.

The DS-SP24 allows the us er to sel ect either Bell or Shelving Parameters and assign them independently using t he 5 available filters.

In order to select the filter's ty pe, it is n ecessary to have the filter's GAIN=0.0dB, then using the “PM2” encoder, rotate it “clock wise” in order to decide the Bell filter's Bandwidth, or “counter-clockwis e” to sel ect the Shelving filter type (Low or High) and its order (1st or 2nd) . So, in order to define the filter ty pe for the filter number 1 (“x”=1), it is necessary from the above Screen, to enter the filter's ed iting page pressing the ENTER button, and the screen has to appea r as follows:

Input-A Gain

-> Gain = + 0.0dB

Input-A Delay

-> Delay = 160.1872mS

Input-A EQ-X

1.00KHz BW1.05 0.0dB

Input-A EQ-1

-> 1.00KHz BW1.06 0.0dB

Page 18

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” en coder c lockwise, the parameter BW will range from 0.05 up to 3 for identifying a bandwid th value for a Bell filter. If a Bell filter is selected, then t he Gain can be modified from 0.0dB and the BW will range between

0.05 and 3. If the user wants to select a Shelvi ng filter from the above setting, with the GAIN=0.0dB [if the GAIN is not 0.0dB, it is necessary t o set it at 0 .0dB using the “PM3” encoder], rotate the “PM2” Counter-clockwise . Once BW r eaches the 0.05 value, at the next step of the “PM2” counter-clockwise r otati on, the selection of the Shelving filters will be entered. Still rotating the “PM2” count er-clockwise, the Shelving filters and their order will be se lectable in the following sequenc e:

1. 1st Order Low Shelving = -6LoSh [ on the screen]

2. 2nd Order Low Shelving = - 12LoS h [on the screen]

3. 1st Order High Shelvin g = -6HiS h [on the screen]

4. 2nd Order High Shelvin g = -12Hi Sh [on the screen]

Once the desired Shelvi ng filt er is selected, the “PM3” can then be used to select the desired GAIN and when the GAIN is set at a value differ ent from 0.0dB, then the filter type cannot be changed until this GAIN is returned to 0.0 dB.

BELL Filter: As an example, if w e want to s et a bell filter within EQ-1, then the BW has to be set at a desired value of say 1.00 u sing th e “PM2” encoder, the GAIN at say +3dB using the “PM3” encoder and the center Fr equen cy at say 1.00KHz with the “NAV/PM1” encoder. The EQ sub-menu screen wi ll show t he following:

Once in the Bell Filter's edit scr een all the filter's parameters can be modified using the “NAV/PM1”, “PM2” and “PM3” encode rs for editing the Filter's Center Frequency, Bandwidth BW and Gain. The Center Frequency of the Para metric Filter can be edited using the “NAV/PM1” encoder, the BW the “PM2” encoder and the Gain the “ PM3” encoder:

“Center Frequency”: the sele ctable frequencies range is from 20Hz to 20kHz in steps of 1/24 of an Octave and can be adjuste d by rota ting the “NAV/PM1” encoder. “Bandwidth BW”: the selectab le BW ran ge is from 0.05 Octave to 3 Octave in steps of 0.05 Octave and can be adjusted by rota ting th e “PM2” encoder. “Gain”: the selectable Gain ra nge 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 wa nt to set a low shelving filter within EQ-1 then the “PM2” encoder has to be rotated co unter-clockwise until the desired Low Shelving fil ter say - 6LoSh appears on the screen, th e GAIN at s ay +3.0dB using the “PM3” encoder and the High Cut Frequency at say 1.00KHz with th e “NAV/PM1” encoder. The EQ sub-menu screen wi ll show t he following:

Input-A EQ-1

->1.00kHz BW=1.00 + 3.0dB

Input-A EQ-1

->1.00kHz -6LoSh + 3.0dB

Page 19

Note: Once the desired Lo w Shelv ing filter is selected, the “PM3” can then be used to select the desired GAIN and when the GAIN is se t at a value different from 0.0dB, then the filter type cannot be changed until this GAI N is retu rned to 0.0dB.

Once in the Low Shelving Fi lter' s edit screen all the filter's parameters can be modified using t he “NAV/PM1”, “PM2” and “PM3” encode rs for editing the Filter's High Cut Frequency, Filter's Order and Gain.

● Input and Output Channels Last Edited Parame ter Return Function

Once you have escaped out o f param eter editing within the individual Input or Output channels t he DS-SP24 will remember t his las t editing action on that Channel. When you return for your next editing action pressi ng the ED IT button on that channel will immediately return you to the s creen related to this last editing act ion.

This function makes fine tunin g or modifying easier when it is necessary to make a number of adjustments to the same parame ter in a short time sequence.

● Input Channels and output Channels LINK Func tion

The DS-SP24 is able to perform a uni que LINK MODE between Input Channels as well as a link between Output Channe ls to ena ble quick and immediate editing (you cannot link outpu t to input channels).

To link channels when editi ng, you will need to select a “Master” channel that will be the one to be edited and have it’s parame ters displayed on the LCD screen. You can then select and link o ther channels (Slaves) tha t you wis h to apply the same changes to.

To enter a link mode session, s elect t he Master channel Edit mode, then link the Slaves by pressing their relate d Edit bu ttons. All Linked channels wil l be selected ready for adjustment when their “Blue” LED is lit in th e Editi ng mode. Now all Slave channels an d only those selected will modify their parameters accordin gly as you edit the Master channel . All other existing para meter s will stay the same within the Slave Channels unless edit ed by thi s link with the Master chan nel.

Note: The LINK function is NOT a COPY function.

If you want to edit the limiter of the O utput c hannels 1, 2, 3 and 4, you can enter the editing mode of Output Channel 1 by press ing the r elated Edit button and turning on the “Blue” LED below the Output Channel 1 LED mete rs. This assigns the “role” of Master and displays this channel’s Parameters on the LCD:

Out-1 Name Polarity

-> Polarity = Normal

Out-1 Name Limiter

A: 5ms R: 0.2s +5.0dB

Page 28

Then press the Edit button of Outp ut Channels 2 and 4, turning on their related “Blue” LED’s. Now all parameters edited o n Outpu t Channel 1, will also be applied to channels 2 and 4. If you want to remove one of the linke d channels from the Link, press the related Edit button. Exiting the editing of the Maste r channel during a Link session will automatically terminat e that session. The Link will also b e automatically terminated if, during the editing of Output C hannels You jump across to begin ed iting an Input channel or vice versa.

● Factory Reset

In the event of the password being l ost or any other reason the user may require the unit to be reset to the original factory se ttings, a “Factory Reset” that will clear all settings of the DS-SP24 and return the device to the origi nal factory setting, is available to the user.

Note: Continuing with t his pro cess will mean the DS-SP24 will re-initialize to the ori ginal f actory settings and any previo usly st ored information and changed parameters will be perm anently lost.
