Introduction
Getting Started
Installation and Setup
The UNIKA DSP speaker management processors can be operated from their respective front
panels or control panels to a varying degree, depending on model. However, for maximum
exibility, remote operation from a Windows PC as well as from an Apple computer running OSX
is also possible; for this remote functionality, the device must be connected via a wired Ethernet
or a USB connection to the same network as the control computer. The control computer can be
connected to the network wired or through Wi-Fi.
● It is recommended that a router with DHCP server is connected to the network so that it assigns
the unit an IP address.
● When the controller is connected to the network, you can check or set its IP address via the unit
window under Hardware - > Congure - > Network Settings → IP address.
The default setting is DHCP (Auto IP).
● If Fixed IP address has been set, and this is no longer known or been forgotten, it can be
requested via the display on the device. Press the menu button four times and turn the encoder
wheel to the right three times to display the IP address.
● Note: you cannot connect the unit to the network through the USB or Ethernet at the same time.
You can only control the unit from one platform at the same time – if you switch from one
platform to another, you MUST shut down the control software at the previous platform rst.
● Local connectivity of the device to the control computer from a front-panel USB connector is also
possible to download initial settings or as a fallback in case of network failure.
● This Software Manual explains the remote setup and operation of the system through a network.
The operation is basically same for all platforms; where differences exist they will be noted.
● Download and install the latest software from the UNIKA website. Note that for a Windows
computer, there are separate applications for Windows 32 bit and 64 bit.
http://www.unika.com.tw
● The software consists of a network window that list all known UNIKA DSP devices on the local
network, and one or more unit windows for settings of a device. In the following sections we will
discuss the Unika DSPControl program for Windows.
● The mac version works very similar to the Windows version.
The mac menu bar is different from Windows for most program, the same differences are
present with DSPControl.

Unika DSPControl
Figure 1: DSPControl network panel
Figure 2: Tools menu items
● The Windows Unika DSPControl Network window is shown in Figure 1: DSPControl network
panel. During installation your rewall setting are congured to allow communication over the
network.
● Switch on the DSP and launch the DSPControl software. It will show the devices found on the
network together with their mac address and IP address, similar to Figure 1.
● Note: you can control the unit from only one PC at the same time. If you want to switch control
from one to the other, shut down the Unika DSPControl software on the previous control platform
rst.
● The ‘>’ icon at the right side may be either > or >. When >, the unit is on line and can be
activated by clicking the >.
The main purpose of the control app is to select a particular unit for manipulation and/or to group
several units in a Group.
The available Tools commands are shown in Figure 2: Tools menu items.

DSP Audio Processor
1. Tools
● 1.1 Tools | Set Software Password
Allows you to set up a password to access the graphical DSP software unit window. The
DSPControl software has a separate, extensive system of operation modes.
Note: you can modify the Unit Name in the Unika- DSPControl program slot for the connected
unit by just typing a new Name.
● 1.2 Tools / New Group
This command allows you to combine several on- line units into a named group. The group will
be shown in the Control screen, see Figure 3.
Clicking the cross icon on the right deletes the
Group; clicking the blue tool icon opens a screen
where you can select the members of the Group;
you will be able to select any unit which is on-line
to become a member of the group.
A further selection from this screen opens a
dialog where you can specify which parameter,
for which setting and for which channel you wish
to link within the Group.
For instance, you can link only gain, or gain and
PEQ settings for Input & Output channels.
An example Group setting screen is shown in
Figure 4.

DSP Audio Processor
● 1.3 Tools / Enter Demo Mode
Allows you to exercise the functionality of an Unika DSP unit without hardware present for
training and familiarization purposes.
● 1.4 Tools / Disable / Enable Updates
When set to Enable Updates, there will be an indication when rmware updates for the unit will
be available. This is shown on the right edge of the unit identication in the control program with
a ‘rotary’ icon, see Figure 5. The icon turns yellow color when updates are available. Clicking
the icon will initiate the update.
This is a ‘brute force’ update which will also restore the unit after a crash or other unrecoverable
situation. All presets and other settings will be lost however.
Clicking the green > symbol at the right of the connected unit info line in the Unika DSPControl
window will load the software for the unit. At this point, the software will go through a
synchronization cycle and, if a Personal Identication Number (PIN) was dened before, will ask
for the PIN.
The Main graphical interface screen will come up similar to Figure 6; this is the opening screen of
the actual application controlling the settings of the unit.
● 1.5 Other Settings
● 1.5.1 Power-On Preset
In the menu item Hardware - > Congure - > Power On Preset, a preset can be selected, which
is automatically loaded when the device starts.
● 1.5.2 Read Only Preset Range
When you are logged on as Developer or higher, you can block a certain preset range from
being altered.
In Hardware - > Congure - > Read-Only Preset. If the value is, for example, set to 10, the rst
10 memory locations in the preset list for User and Admin mode are read only and the user
cannot save presets to those locations.
Figure 5: rotary’ icon yellow color at right indicates rmware update for this
unit is available

2. Unit Window: Main Panel
Figure 6: unit window
● 2.1 Unit Window Menu
Figure 6: unit window shows the unit window from which all setup screens and options can be
reached. Clicking the exit cross will close the software but leave the network Control program
running.
● 2.2 File Commands
● 2.2.1 File / Open and File / Save
Presets are the snapshot of all settings for a particular conguration. With these commands you
can save a preset, and reload it at a later time. In addition it offers the choice to use the .preset
le format or the .txt format. Text les are a way to archive settings for documentation purpose.
● 2.2.2 File / Backup presets and File / Restore presets
These commands operate similarly to Save and Open, but will save all presets in the unit in one
directory, or load all presets from a directory.
● 2.2.3 File Quit –
self-explanatory

DSP Audio Processor
● 2.3.1 Hardware / Enter Password
The unit has three access levels plus locked. Entering the right access level password unlocks
that access level. Please see password protection, access control & locking.
● 2.3.2 Hardware / Congure
The Congure menu item opens an additional screen where several options are presented. However,
the options shown will depend on the access level currently in force – to be discussed.
● 2.3.3 Hardware / Congure / Power On Preset
Allows you to select a preset that will be automatically loaded at power-on;however any
changes to this preset will not be carried over to the next power-on cycle unless you have
saved the new setting, i.e. it will revert to the saved preset.
● 2.3 Hardware Commands
The Hardware menu offers several functions as shown in Figure 7: unit panel Hardware menu
items.
Figure 7: unit panel Hardware menu items

DSP Audio Processor
● 2.3.4 Hardware / Lock Unit
Clicking this menu item will lock the unit. When locked, the unit window shows input levels but
no controls or other settings, and nothing can be changed, as shown in Figure 8: detail of unit
panel in locked state.
An attempt to lock the unit will generate a warning that unlocking will only be possible with a valid
password. The actual operation of this function depends on the access level as described later.
● 2.3.5 Hardware / Go to Standby
Will place the unit in Standby. In this state, outputs are disabled but all settings can still be
manipulated.
● 2.3.6 Hardware / Set PIN
Clicking this option allows you to enter a 4-digit PIN number. When this is set, you will need
to enter the PIN number at any time you connect to the unit. Note: the PIN control can be
switched off by setting the PIN to 0000.
Figure 8: detail of unit panel in locked state.

DSP Audio Processor
● 3.1 Unit Window Functionality
On the left side, the Unit window (Figure 6) gives access to the cross-over settings screen
as well as all settings screens for each individual Input- and Output channels. These will be
discussed later. The following commands are found in the center of the Unit window:
● 3.1.1 Presets - Local
These commands allow you to save and re-load congurations as .preset les on the connected PC.
● 3.1.2 Presets - Unit
These commands are similar as the other Save and Load commands but with the distinction
that presets can be saved to and reloaded from the unit internal memory. The drop-down menu
under Default Preset shows a list of memory slots where named presets can be stored and recalled.
Since this is internal in the unit they will be available independent of the stored presets in a computer.
● 3.1.3 Link
Under Link there are several status related indications. The indicator at the right will be green
for an active link with the unit or red when the unit is off-line. The name and MAC address of the
connected unit is also shown.
● 3.1.4 Unit Name
Shows the unit name of the connected unit,
which can be edited by typing in a new
name. The new name will be reected in the
Link slot as well as in the name eld in the
Unika DSPControl window.

DSP Audio Processor
● 3.2 Unit Window Channel Settings
On the right side are the Channel settings.This area is divided into several subsections:
● 3.2.1 Level Faders for Input Channels
These faders control the level from each of the physical input connectors as sent to the Input
processing channels. Channel names are shown at the bottom line. Level settings are also
shown numerically below the faders, and can also be set by entering a specic value in the
corresponding text eld.
● 3.2.2 Input Selection for Input Faders
When your unit is equipped with AES3 (AES/EBU) or Dante inputs, you can select the source
for inputs 3 and 4 from this pull down menu.
● 3.2.3 Level Faders for Output Channels
These faders control the levels for the physical Output channels at the rear-panel output
connectors. Level settings are also shown numerically below the faders, and can also be set by
entering a specic value in the corresponding text eld.
Faders auto-zero:
Whenever you double-click on a fader, that fader moves to the default
position. This is usually 0dB (unity gain) for gain faders. This operates on all views and screens.
When two channels are linked, the odd-numbered channel can be used to manipulate both linked
channels.
● 3.2.4 Link Buttons
When activated, all settings for the related pair of channels pairs are linked together and can
only be changed with the left (odd numbered) fader of the pair the right fader will follow.
Similarly, entering numeric values in the level elds will only be accepted for the left channel of a
pair, with the right-channel numeric value following, the even- numbered channel of a linked pair
will be unresponsive but follow the odd-numbered channel settings.
To reset a paired level to 0dB you must therefore double-click the odd-numbered fader.
● 3.2.5 Mute Buttons
Mute buttons allow muting of an Input- or Output channel on a per-channel basis, independent
of any linking in effect.
10
DSP Audio Processor
● 3.3 Digital Inputs (Option)
When your device is equipped with AES3 (AES / EBU) and/or Dante input, you can set the
source of input channels 3 and 4.
The AES-3 (AES / EBU) input signal can be fed via AES XLR socket in the controller. The Dante
input is fed to the units via the same RJ45 connector that is also used for control.
Available input sources: Analog, AES-3 and DANTE.
● 3.3.1 AES Failover
In the menu item Hardware -> Congure -> AES analog failover, a radio button can be turned
on so that when there is no AES / EBU signal, the unit automatically switches to the analog input.
4. Input Channel Settings Screen
Figure 10: Input channel settings window
Figure 11: Input signal ow
Clicking on an Input channel number in the Unit window will bring up the input channel settings
screen see Figure 10. In this screen, individual input channels can be equalized and/or ltered.
11
DSP Audio Processor
● 4.1 Filtering and EQ
All input channels can have filtering and equalization applied individually, or as linked pairs.
Input channels can be linked in the Unit window, and in that case, all EQ and lter settings for
the pair will be linked.
If input channels are linked, EQ and lters for each pair can only be set for the odd number for example, setting an EQ for input channels 1 and 2 can thus only be done in the Input 1 screen.
EQ can be set either in the graphical screen by cursor dragging, or in the numerical elds and
drop- down lists below the graphical screen.
Type, Freq., Q/BW and Gain can be set for each input or pair of linked inputs.
All settings are reected real-time in the graphical screen.
The Q/BW column toggles from indicating Q or bandwidth (BW) every time the column label is
clicked.
● 4.2 Input Channel Transfer Function Curve
On the graphical screen, a white curve represents the compound transfer curve for that input
channel.
The various elements that make up the curve like EQ settings and the crossover filters are
indicated by their respective colors and EQ numbers.
There are two ways to toggle the contribution of an EQ or crossover element to the white
compound curve on or off. You can either click the black/blue button next to each EQ or the
HPF or LPF lter at the bottom of the screen, or you can double-click on the numbered square
of the elements in the graphical screen. Even if the effect of the element on the compound
curve is removed, the colored non-contributing curve of the element remains visible. This is a
useful functionality to review the contribution of several interacting lter and EQ settings on a
channel.
F i g u r e 1 2 : p r e c i s e s e t t i n g t o o l s
● 4.2.1 Screen Expansion and Legends
On the left-hand side of the graphical screen are four icons
to help precise settings. The top Arrow icon expands the
graphical screen to the size of the window. Clicking this icon
again from the expanded screen expands it to the full display
size. In either of the expanded settings, clicking the X-icon at
the top left will collapse the graphical area to the default setting.
12
DSP Audio Processor
The Camera icon will generate a .png picture le similar to a screen shot which you can save for
documentation or instruction purposes.
The
T
(text) icon will place the frequency, Q and gain values of each EQ and lter setting in the
graphical screen. These settings will anyway be visible when changes are being made, but with
the T icon activated, they will be visible continuously. This duplicates the numerical indications in
the lower part of the screen but it will be useful with the expanded screens mentioned before.
For very accurate settings of EQ or ltering you can click the Looking Glass icon. All movements of
the cursor now have a much smaller effect and you can drag curves with much greater precision,
clicking the Looking Glass again reverts to normal operation.
● 4.2.2 Input Gain, Mute
The right hand side of the screen shows the fader to set Input channel gain and a Mute button.
Settings are individual per channel unless input channels have been linked in the Unit window.
● 4.2.3 Delay, Limiter, Compressor
In the bottom right of the Input screen there are settings for channel delay, limiter threshold
(-48 to +24 dBu) and Limiter release rate (10 to 100 dB/s) settings plus a button to enter the
RMS Compressor menus. Channel delay can be set in a variety of distance or time units from
the drop-down list.
Figure 13: Detail of Delay, Limiter & Compressor in input- window
13
DSP Audio Processor
● 4.2.4 RMS Compressor
Clicking on the compressor button brings up the
compressor menu Figure 14.
In the compressor menu you can set the
parameters of the RMS Compressor, the
threshold, attack, hold, and release time, the
compression ratio and the make-up gain
.
Next to the controls is a VU meter that also
displays the gain reduction (GR). Be sure to use
the ‘
Back
’ button to return to the output menu.
When you click X-over in the left unit window function list, most of the screen is dedicated to the
controls and indicators for setting up the cross over lters as shown in Figure 15.
● 5.1 Graphical Control
The graphical window shows the crossover settings for each of the output channels in dedicated
colors. The numbers for each channel have a triangle shape and the direction of the triangle
denotes whether the triangle controls the upper or lower corner frequency setting.
Figure 14: Compressor settings window
Figure 15: Crossover window
5. Crossover Settings Window
14
DSP Audio Processor
For each channel, the cross-over frequency on either side of the band can be set with the cursor
or by entering a value in the numeric elds below the channel. To change the frequency setting
by mouse, move the cursor over the number of the channel you want to change in the graphical
screen until the cursor changes to a 4-way arrow. Now you can click- and-drag the number triangle
and the frequency value will change real time, and will be reected both in the screen curve and
the numerical value. Frequency limits are 20Hz and 20kHz in each case.
● 5.2 Filter Type
The lter type and slope for each Output channel and at each end of the band can be set by
selecting the desired type from the drop-down menu below the graphical area, for that channel.
Separate lter types are available for the HP and the LP setting.
● 5.3 Gain
The Output channel gain, in dB, can be set by entering a numerical value in the eld indicated by “G”.
Note: the Gain value entered here will be reected in the setting for the channel in the Unit
window level setting; Alternatively, changing the Gain setting for a channel in the Unit window
will be reected in the Crossover screen gain setting!
● 5.4 Delay
For each channel a delay can be introduced in the numeric eld indicated in milliseconds.
● 5.5 Link
When two channels are linked by activating the related Link button in the top right-hand side of
the screen, the settings for that pair are combined and only a single color and number icon for
the pair is shown in the graphical screen (only the odd number of the pair is shown). Also in this
case, all numerical values and lter types for the two channels are linked and can only be
changed in the left hand side (odd numbered) channel of the linked pair.
Note: Changing the Link status of a pair of Output channels will also be reected in the Link
status for that pair in the Unit window; alternatively, changing the Link status for a pair in the
Unit window will also carry over to the Crossover screen!
● 5.6 Mute, Phase Invert
The top right side of the screen shows these additional options which are self-explanatory.
Changes to the Mute status of a channel or channel pair will also reect in the Unit window
and vice versa. Mute status of an individual channel can be changed independent of whether a
channel is linked to another channel. However, the Phase invert status will be link for two
channels if the channels are linked.
The phase invert button changes the polarity of the output channel. The signal is changed 180
degrees.

DSP Audio Processor
6. Output Channel Settings Window
Figure 16: Output channel window
Figure 17: Output signal ow
● 6.1 Input Output Matrix
Figure 16: Output channel window, faders are shown for each of the input channels. This will
allow mixing each of the input signals to each individual Output channel. Even if Input channels
are set to Linked in the Unit window, it is still possible here to mix individual Input channels to an
Output channel in any desired ratio. Level settings are shown numerically below each fader.
The available range is from -48 dB to 0 dB, as in other screen, double- clicking a fader resets it
to default.
● 6.2 Graphical Screen
A complete control screen is available for each Output channel. The graphical area reects the
Crossover settings for the channel in addition to any equalization settings set up in this screen,
and is very similar to the available settings in the Individual input channel screens. The status of
an element is always reected in the blue on/off button next to each element.

● 6.3 Relationship between Input- and Output Settings
At the bottom of the Output channel settings screen (Figure 16) you will see the high-pass and
low-pass settings from the cross-over settings for the particular Output channel repeated. Both
the slope and the lter type are shown, and the curves are also shown in the Output graphic
screen. Any changes you make here are also reected in the X- over screen. This way, you
have control over the main crossover settings as well as the EQ and ltering for a specic
Output from a single screen. In contrast, the crossover screen gives you the overview of all
cross-over settings for all channels in a single screen.
Both the HPF and LPF lter can be disabled here, this will also be visible in the Crossover screen.
● 6.4 Output Filtering and EQ
Similarly as described for the Input channels, each Output channel can have up to 10 EQ’s and
lters attached to it (Figure 16). For each of these, EQ type, Frequency, Q or BW and Gain can
be set.
Each EQ can be set in the graphical screen by dragging the appropriate EQ number as
described earlier, as well as by entering the desired numerical values in the elds. When using
the mouse to drag settings, the actual numerical values for Gain, Q or BW and Frequency are
shown in the screen.
Note: The four icons in the top left area of the screen (expansion arrow, camera, ‘T’ and
Looking Glass) act as described for the Input screen.
● 6.5 Output Channel Transfer Curve
On the graphical screen, a white curve shows the compound transfer curve for that output
channel.
The various elements that make up the curve like EQ settings and the crossover lters are
indicated by their respective colors and EQ numbers.
Note: that the white compound transfer curve also reects any cross-over settings made in the
X-over screen, when activated.
● 6.6 Delay, Limiter, Compressor
Like the input channel, each output is also equipped with a dynamics processing section.
The compressor and limiter at the output limits the entire signal. In the bottom right of the output
screen there are settings for channel delay, limiter threshold (-48 to +24 dBu) and Limiter
release rate (10 to 100 dB/s) settings plus a button to enter the RMS Compressor menus.
Channel delay can be set in a variety of distance or time units from the drop-down list.
17
DSP Audio Processor
● 6.7 RMS Compressor
Clicking on the compressor button brings up the
compressor menu.
In the compressor menu you can set the
parameters of the compressor such as threshold,
attack, hold and release times, ratio and makeup gain.
Next to the controls is a VU meter that also displays
the gain reduction (GR). Be sure to use the ‘Back’
button to return to the output menu.
Note, is selected equipment with power amplication
built in, it is possible to set the threshold as an
absolute (RMS) voltage. The system then displays
the corresponding output power for 4 and 8 ohms
loudspeaker system. This makes it easy to set the
maximum power that power amplier will apply to
the connected loudspeaker making it easy to set
the threshold so that the attached loudspeaker is
not thermally overloaded.
Note: Applying too much electrical power is not the
sole failure mode for a loudspeaker. Applying power
outside of the rated frequency range can easily
damage a loudspeaker at low power levels. UNIKA
advises to carefully consider the correct settings for
each driver. The RMS Compressor and Peak Limiter
can be valuable tools to protect drivers, but will not
guarantee that the driver cannot be damaged.
Figure 18: Output RMS Compressor
● 6.8 Change / Adjusting Values
To change a value in the input elds in a Windows PC, it is also possible to adjust the value
using the arrow keys or the scroll wheel on the mouse.
18
DSP Audio Processor
This unit has three access levels, plus locked mode. It is intended to enable the right amount of
control to each type user.
The three levels are:
● User
(user of the system)
The user is the person that makes use of the system that the DSP product drives. This can
be the FOH engineer, venue engineer. This user level has the lowest amount of control of the
conguration.
● Administrator
, e.g. installer, sound system designer…
The administrator is the person that changes the system. In some cases this can still be the DJ
or FOH engineer, typically when they are familiar with the venue. It can also be the designated
maintenance engineer.
● Developer
(the person responsible for the acoustic performance)
The developer tunes the crossovers, equalizes the outputs, and sets the output limiter so that it
protects the system.
The standard passwords are as follows
User mode: U0000
Administrator mode: Adm0001
Developer mode: Dvl0001
Note: Please change these passwords as soon as possible to prevent unauthorized access to
your system.
Note: Please store your changed passwords securely. There is no way to retrieve lost passwords.
If you break into your unit by setting and forgetting a password, we cannot help you without an
RMA process. Resetting your unit can only be done in the factory. We do not have or give out a
master password. Please head this warning and keep your password in a secure location.
The privileges of each level are now explained in more detail.
At start-up the unit will be in User Mode by default, and will have access privileges as congured
previously for that Mode. There is no specific indication that you are in User Mode. However,
Administrator and Developer Mode will be indicated at the top of the window next to the unit name.
As developer, you have access to and can set all passwords, access levels and privileges.
You should receive a Developer password with your unit; if you log on with that password you can
then set up a User and Administrator password and the privileges for each level as described in
this Chapter.
7. Access Control and Locking
19
DSP Audio Processor
Note:that there is no functional relation between the software password in the network window of
the control software, the PIN control system and the hardware-related access control functionality
for the DSP software. Each operates separately.
If you enter your Developer password, the Hardware drop-down menu will show additional options
that will not be visible in the other modes.
In addition to change your Developer password,you have the option to set the passwords for
Administrator and User modes (Figure 19).
You can also set all Access rights for the other modes as shown in Figure 20.
Figure 19: Additional functionality available in Developer mode
Figure 20: Developer can set Access rights for all other operation modes.
20
DSP Audio Processor
For each level, there is a dialog screen with privileges that you can set for that level, accessed
through the Hardware / Access Rights menu. You set the User Mode privileges that are required
to work with the unit as a user, while with Administrator and Developer level access, you can
allow progressively more detailed settings and adjustments to be made. For this reason, the
Access Rights dialog window will show more privileges with higher access levels. The User Mode
privileges list with a sample setting is shown in Figure 21.
A similar screen will be shown for Administrator mode; Figure 22.
Figure 21: Sample User access level privileges dialog box
Figure 22: Administrator access level privileges dialog box.

DSP Audio Processor
Finally, there is a dialog screen to set the access levels in locked level mode as shown in Figure 23.
A typical Locked screen is shown in Figure 24 Sample Locked screen.
Figure 23: Locked level access settings dialog box
Figure 24: Sample Locked screen

DSP Audio Processor
Access rights
Most descriptions are self-explanatory, the following rights can be controlled:
●
Load presets – loading presets from the device preset list
●
Save presets – Saving presets to the device memory
●
Enable Display Lock Control – Locking and unlocking the unit
●
Change Access Rights of Locked level –change the access rights for lower level(s)
●
Change Unit Name
●
Lock Automatically after Power Cycle – The Unit can be set to lock automatically after a power
cycle (be careful, if the user sets this to on he/she may be locked out after a power cycle)
●
Change Unit Conguration – Change the conguration of the Network, Auto-standby, Startup
preset setting. Again, mistakes here can lock a user out of the device control
●
Load an empty Preset – For an experienced user, loading an empty preset can easily reset
the unit for a clean slate. But for an inexperienced user, it can damage loudspeakers. So when
unchecked, the user can only load presets that have been dened
●
Upgrade unit rmware
●
Show full graphics – when checked the full settings, like crossover, EQ, and limiter settings are
visible to the user, even when they cannot be changed.

DSP Audio Processor
8. Firmware Update Process
The controller rmware can be updated via the PC software. It is strongly recommended that the
DSP is updated via the Ethernet interface.
The update is performed in administrator mode.
On models with a display, the rmware version can be checked via pressing the encoder button 4
times and turning the encoder until the rmware version is displayed
.
You can also check the rmware version in the PC software via Help -> about -> version.
An available update is indicated by the sufx "(Update Available)". If an update is available, it can
be performed as follows:
Hardware - > Firmware Update. The program may run in several stages through the update
process.
If the update fails, restart the software and device and try again.
Through a firmware update (at least Admin or Developer mode), all presets from the DSP
controller can be cleared. You will be prompted for the option to backup and restore all presets. If
that is not done, the update removes all presets from memory.
In user-level "Developer", presets can be cleared "Preset" → "Clear all User Presets". All presets
are deleted that are not protected by the "read-only preset range". To clear Read-Only Presets: In
user- level "Developer", choose "Preset" → "Clear all Read-Only Presets".

● 9.3 Features and Benets
● 9.3.1 Presets
The DSP-428 is organized into 100 programmable presets, each completely dening the
conguration of all inputs and outputs along with their respective audio components.
DSP-428 has included 2 factory presets that preloaded into the unit which are simply starting
points for common applications, and all can be modied, rename, and save to suit the end user.
From the DSP Control software, a “Power ON Preset” can be congured that will be loaded
upon powered up of the unit, it is the one selected out of the 100 existing presets, alternatively,
a so called “Last-Setting” preset can be choose as “Power ON Preset”, which is a constantly
refreshed working preset used to take a "snapshot" of all current settings should the unit be
turned off before changes can be saved.
Any modications made to the currently use preset before saving, it will remain in the working
preset until either the modied preset is saved, or a fresh preset is recalled.
Note: that preset recall will overwrite the working preset, so make sure the current conguration
is saved before continuing or it will be lost.
When modications made to the currently use preset without saving, on the front panel LCD
an asterisk mark (＊) will show up at the right end side of the preset name for 3 seconds and
the preset number will changed to an exclamation mark ( ! ). If choosing one of the existing
presets as a “Power ON Preset”, beware of that if you change any setting without saving, this
change will be void after power cycling the unit and the original preset will be loaded again.
The presets can also be saved and recalled as preset les on the connected PC.
● 9.3.2 Input Channel A, B, C, D; Analog Audio, AES-3 Digital Input and
Optional Dante Network
The DSP-428 has provided four audio input channels, all equipped with XLR connectors, each
input is processed independently and may be routed to one or several output, signal routing
occurs in the output section.
Any input channel can be selected to edit its Gain, PEQ, and Delay, Compressor or Limiter
functions etc.
The unit is also equipped with an AES-3 (AES/EBU) digital input and optional Dante network
input, the Dante network input is fed to the unit via the same RJ-45 connector that is also used
for control.
Analog audio, AES-3 digital or Dante network audio sources can be chosen for input channel
C & D but input channels A & B can accepted only analog audio source.
● 9.3.3 Output Channel-1 to 8
There are eight analog outputs on the DSP-428, all equipped with XLR connectors, each output
can obtain its audio source from any input or multiple input mixes, any output channel is
processed independently to edit its Source, Gain, Polarity, PEQ, Delay, Cross-over, Compressor
or Limiter functions etc.
32
DSP Audio Processor
● 9.3.4 LED Indicators
Each input and output channel has a 4 segment LED array for audio level display, ranging from
-48dB (SIGNAL) through clipping (CLIP); the 0dB LED indicate that the signal level is at 0dBu
(0.775Vrms), the LIMIT LED light up indicate the limiter is activated; The red LED aside the
MUTE button indicate that the output channel has been muted when light up.
The LED array of AES / EBU and DANTE lights up indicate that AES-3 digital audio or DANTE
network audio is connected and the audio signal is fed into the unit.
● 9.3.5 Audio Functions
● 9.3.5-1 Gain
Input and Output Gain are separately adjustable from -48dB to +12dB in 0.1dB increments.
The output gain menu also provides for selection of input source(s) for a given output channel,
as well as polarity of the outgoing signal. Any input or combination of inputs can be routed to
any or all outputs. Beware of that two signals which share signicant content, such as a stereo
source, will be up to 6dB louder when combined.
● 9.3.5-2 EQ
The DSP-428 EQ section offers full parametric EQ lters on inputs and outputs, each input
and output channel has 10 selectable EQ lters, lter type is selectable between Bell, Notch,
Low Shelf, High Shelf, All Pass, BandPass, Low Pass and High Pass.
Filter's Center/Cutoff/Corner frequency is adjustable from 20Hz to 20 kHz; ±12dB of boost/cut
control range and -40dB of attenuation range for the Notch lter.
Q factor or BW (Bandwidth) of Bell type lter is adjustable from Q= 0.2 to 25, for Notch lter
Q=10 to 80, for Low & high Shelf lter Q=3 to 25, for Low-pass & High-pass lter Q=0.5 to 2, for
All-pass & Bandpass lter Q=0.2 to 25.
● 9.3.5-3 Delay
Within the DSP-428, up to 2000 milliseconds of time delay are available for input channels,
allowing secondary loudspeaker clusters to be time aligned with the primary speakers up to 2,252
feet (686m) away from the main stage area.
Output channels have the same time delay as well; output delay is best used to align discrete
drivers within a speaker cabinet or cluster, the delay time unit can be selected as Second,
Millisecond, Feet, Inch, Mil-inch, Meter and Millimeter.
33
DSP Audio Processor
● 9.3.5-4 Crossover (X-over)
Crossover functions are available only on the output channels. Every channel's crossover
consists of a high pass lter (HPF) and a low pass lter (LPF), along with the frequencies and
lter types used.
The frequency range for the high pass lter (HPF) is adjustable from 20Hz to 20 kHz, with
an option to turn the lter off at the low end of the frequency selection, the low pass lter (LPF)
offers the same adjustable frequency range, with the "off" option at the high end of the
frequency selection.
There are 10 types of lters available in the crossover section:
1-Butterworth 6dB/Oct
2-Butterworth 12dB/Oct
3-Butterworth 18dB/Oct
4-Butterworth 24dB/Oct
5-Bessel 6dB/Oct
6-Bessel 12dB/Oct
7-Bessel 18dB/Oct
8-Bessel 24dB/Oct
9-Linkwitz-Riley 12dB/Oct
10-Linkwitz-Riley 24dB/Oct
● 9.3.5-5 Butterworth Filter
Butterworth lters individually are always -3dB at the displayed crossover frequency and are
used because they have a "maximally at" passband and sharpest transition to the stopband.
When a Butterworth HPF and LPF of the same crossover frequency are summed, the combined
response is always +3dB.
With 12dB per octave Butterworth crossover lters, one of the outputs must be inverted or else
the combined response will result in a large notch at the crossover frequency.
● 9.3.5-6 Bessel Filter
Bessel lters individually are always -3dB at the displayed crossover frequency and are used
because they have a maximally flat group delay, in other words, they have the most linear
phase response.
When a Bessel HPF and LPF of the same crossover frequency are summed, the combined
response is +3dB for 12dB/oct and 18dB/oct Bessel lters, and -2dB for 24dB/oct Bessel lters.
One of the outputs must be inverted when using either 12dB/oct or 18dB/oct Bessel crossover
lters or else the combined response will have a large notch.
● 9.3.5-7 Linkwitz-Riley Filter
The 12 dB/oct and 24dB/oct Linkwitz-Riley lters individually are always -6dB at the displayed
crossover frequency.
When a Linkwitz-Riley HPF and LPF of the same displayed crossover frequency are summed,
the combined response is always flat. With 12dB/oct Linkwitz-Riley crossover filters, one of
the outputs must be inverted or else the combined response will have a large notch at the
crossover frequency.
34
DSP Audio Processor
● 9.3.5-8 Compressor & Limiter
A full function RMS Compressor and a Peak Limiter are included on each input and output
channel.
The limiter is commonly used to prevent transient audio signal spikes from damaging
loudspeakers, the compressor is used to maintain the dynamic range consistency of the audio
signal and to "thicken" the sound of the audio source; the adjustable parameters include
Threshold, Ratio, Attack Time, Release Time and make-up Gain.
The DSP-428 limiter threshold range is adjustable from -48dB to +24dB, this setting determines
the signal level above which gain reduction begins, and is indicated by the yellow (LIMIT) LED
in the output meter section.
The increase of the audio level exceeding the threshold will be limited because the limiter ratio
is xedly set to INF: 1, and the Release time can be adjusted from 10dB/sec to 100dB/sec.
The DSP-428 compressor threshold range is adjustable from -48dB to +24dB, the compression
ratio control determines the amount of gain reduction above threshold; the compression ratio
can range from a mild 1.2: 1 adjustment to a brick wall INF: 1.
The Attack time and Release time settings adjust the time it takes the compressor/limiter to
engage and then disengage when the signal increases above threshold and then subsequently
falls back below threshold.
The attack time is adjustable from 1.0ms through 10.0s, while the release time ranges from
1.0ms through 10.0s. Compressor’s Hold time is adjustable from 1.0ms to 10.0s and make-up
Gain from -12dB to +12dB.
● 9.3.6 Copy and Paste
The Copy and Paste function is used to quickly transfer the settings from a currently selected
item’s parameter to another input or output channel.
Press the COPY key to copy the currently displayed item parameter values to the clipboard.
Use the CH.UP or CH.DOWN keys to navigate to the same item of the desired target channel
to paste the data into it.
Press the PASTE key to paste the parameter value into the target channel item, and then press
the encoder to conrm completion.
● 9.3.7 Mute
Mute button allow muting of an Output channel, pressing the Mute button will toggle its mute
function, the output's red Mute LED will lit when muted.

DSP Audio Processor
● 9.3.8 Interconnection
● 9.3.8-1 Audio Connections
The DSP-428 analog audio connections use three pin XLR connectors, with pin 2 (+), pin 3 (-),
and pin 1(G). Inputs and outputs are electronically balanced.
If an unbalanced signal is fed to an input, the signal should be on the (+) connection (pin 2) and
pin 3 must be tied to ground or signicant signal loss will result.
The AES-3 digital input signal can be fed via (AES / EBU) XLR socket on the controller rear
panel.
Note: This unit is designed to clip at signal levels above +20dBu = 7.75Vrms which places the
noise oor lower than -90dBu. The optimum input signal level which should be fed into the DSP428 is 0dBu = .775Vrms. This input level will allow 20dB of headroom while giving a nominal
signal that is >90dB above the noise oor.
● 9.3.8-2 Ethernet & Dante Network Connections
A RJ45 Ethernet port is provided on the rear panel for networked control.
The Dante input is fed to the units via the same RJ45 connector that is also used for control
.
For detailed information regarding the implementation of Ethernet control please see the UNiKA
DSPControl Software section.
● 9.3.8-3 USB Connection
The DSP-428 has provided an USB port on the front panel, a USB-A to USB-B cable is provided
with every DSP-428 unit to connect to a computer running Unika DSPControl software.
