Overview Described below are the functions of the front panel control buttons and encoders for The DS-SP24.
Getting Started Using Front Panel Interface Getting Started When the DS-SP24 is turned ON the device model name will appear in the LCD screen: DS-SP24 GALAXY Audio A status bar will show the progress of the DS-SP24 initialization process: DS-SP24 The DS-SP24 has two factory pre-set working modes: “1x2 Way X-Over” and “4 Way X-Over”. After the initialization, the DS-SP24 will show on the LCD the first of the embedded preset working modes, or the last one selected prior to the unit being turned off.
• Encoders and ENTER, ESC buttons The DS-SP24 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.
● Menu “UTILITY” [access by pushing the “UTILITY” button] From the “Default Screen”, it is possible to access the “UTILITY” menu by pushing the “UTILITY” button and the Sub-Menus pages can be selected by rotating the “NAV/PM1” encoder clockwise and counter-clockwise. Once selecting the sub-menu page, using the “ENTER” button will access the Sub-Menu pages, again “scrollable” using the “NAV/PM1” encoder and accessible for parameter editing again pushing the “ENTER” button.
When the “1x2 WAY XOVER” is selected, the “System Setup” page will appear as follows: System Setup Setup: 1x2 WAY XOVER * To change the desired operating mode for the DS-SP24, the screen must reflect the X-Over required and then simply pressing the “ENTER” button will bring up the following screen asking for confirmation to load the selected operating mode: New Xover [Enter] to confirm If confirmed by pressing ENTER the selected preset mode will load.
– Delay Time/Distance: this page allows you to select the measurement unit to be used for the Delays: Time (in milliseconds “ms”) or Distance (in meters:“m”) SYSTEM UTILITY - Delay Units - By pressing ENTER and rotating the “PM2” or “PM3” encoder, it is possible to select the measurement unit to be used for the delay, which will be confirmed by pushing the ENTER button.
If presets have previously been stored by the user, anyone of them can be recalled: [ENTER] to Recall. 01: PRESET 1 By using the “PM2” or “PM3” encoder it is possible to scroll through the stored presets. Once the desired preset appears on the screen select it by pressing the “ENTER” button and this will force the DS-SP24 to begin to load this selected preset and the following transitory screen will appear: Loading New Program . . . . .
When storing an edited configuration for the DS-SP24, select the location for a preset from the 24 available by using the “PM2” or “PM3” encoders. Once the desired location appears on the screen press ENTER again to reach the “Set Program Name” page. In this page the User can enter a Preset Name (up to 16 Characters) by using the “PM2” or “PM3” encoder to choose a character and the “NAV/PM1” encoder to move between the 16 available locations for the character’s positioning.
If you wish to proceed press “ENTER” again and the DS-SP24 will go ahead with the “Set Program Name” page and the subsequent overwrite on completion of the previously described storing process. Note: At any time it is possible to quit the storing action by pressing the “ESC” button.
Note: At any time it is possible to quit the deleting action by pressing the “ESC” button. Interface Utilities Sub-menu – this sub-menu allows you to define the remote control interface [USB or RS485] to be used for controlling the DS-SP24: - UTILITY MENU Interface Utilities - From “Interface Utilities”, press “ENTER” to access the Interface Setup. – Interface Setup: this screen allows you to choose the remote control protocol for the DS-SP24.
Press ENTER again and use the “PM2” or “PM3” encoders to scroll between the “be shown” and “not be shown” options. An asterisk will highlight which option is selected. Choosing the “be shown” option means that once the unit is locked, you cannot access parameter editing features, but they will be displayed on the LCD screen. Choosing the “not be shown” option means that once the unit is locked, the parameters will not be shown at all.
Using the “PM2” or “PM3” encoders to choose a character and the “NAV/PM1” encoder to move between available locations you can enter a 6 Character Password Name. The current position of the cursor for the characters to be entered is shown by a “blinking underscore”.
Once a Password has been entered into the DS-SP24 through the steps described in the previous paragraph, it is possible to “Enable” or “Disable” the password function and therefore lock the DS-SP24 restricting access to all functions. When a password has been entered you will be able to select the “Enable” option from the menu and the unit will not be accessible for editing.
Gain page – from this screen it is possible to set the Input Channels Level from -12dB to +6dB, press ENTER 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 or B. The following is an example screen for the “Gain” page that has set the Gain of Input Channel A to +0.0dB: Input-A Gain -> Gain = + 0.
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.
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.
● Menu “Output 1/2/3/4” Output Channels Editing [access by pushing the “1/2/3/4” buttons] From the “Default Screen”, it is possible to access the “Output Channel” menu by pressing the “1” or “2” or “3” or “4” 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 “->”.
LPF sub-menu – from this sub-menu it is possible to set the Output 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 Output1... using the name “Low” (see later for assigning a Name to the outputs): Out-1 Low LPE -> 20.0 Hz Lnk/Ril 24dB 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.
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.
To Edit press ENTER on the Name Page and the entering arrow will appear as in the example below: Out-1 Low -> Name = Low Name The first letter position will be blinking. Select the Character position from the 6 available by rotating the “NAV/PM1” encoder, then by using the “PM2” or “PM3” encoder it is possible to select the desired character. Once you are happy with your name selection, press “ENTER” to confirm the edited Name. The New name will be stored.
Limiter sub-menu – from this page it is possible to set the Output Channels Limiter. The following is an example screen for the Limiter page where the Attack Time of the Limiter is set at 5ms, the Release Time is set at 0.2Sec and the Limiter Active Threshold is set at +5dB: Out-1 Name Limiter A: 5ms R: 0.2s +5.0dB Once pushing ENTER the Limiter's parameters can be modified using the “NAV/PM1”, “PM2” and “PM3” encoders for editing the Limiter's Attack Time [A], Release Time [R] and Active Threshold.
Polarity page – from this page it is possible to set the Output Channels Polarity, by using the “PM1” or “PM2” encoders. The polarity can be “Normal” or “Inverted” (which means rotated of 180 Degrees).
Then press the Edit button of Output Channels 2 and 4, turning on their related “Blue” LED’s. Now all parameters edited on Output Channel 1, will also be applied to channels 2 and 4. If you want to remove one of the linked channels from the Link, press the related Edit button. Exiting the editing of the Master channel during a Link session will automatically terminate that session.
