Drive Modules
The DNA SC48 processor has a new way of ordering and grouping channels in order to give a more
loudspeaker-based approach to controlling, designing and recalling loudspeaker configurations;
these are called Drive Modules. A Drive Module is the Processing provided by one Input DSP Block,
and a number of Output DSP Blocks, which are associated with one-another by means of routing. For
example, if Input DSP Block B is routed to Outputs 3 and 4, then this is a 2-way Drive Module with
Input DSP Block B forming the ‘Master’ control, and Output DSP Blocks 3 and 4 providing the driver-
related control. Overall, this forms the processing typically for one loudspeaker sub-system. The
System Engineer Drive Module control panel for this sub-system may then be used for control and
monitoring of the associated loudspeaker.

13
Drive Modules may be included in Module Groups, which use the Parameter Overlay feature in the
SC48 to achieve trouble-free Grouping in the System Engineer application.
The Presets in the SC48 are Drive-Module centric, and are used to configure individual Drive
Modules rather than the whole device.
Importantly, Drive Modules move the focus away from the processing device, and onto the
loudspeaker systems.
Component Presets allow the Drive Module Presets to be broken apart, allowing any output to be
used for any component within a Drive Module Preset (i.e. any driver in a loudspeaker subsystem).
See Overview of Modules
Overlays
When the SC48 is used in Modules view in System Engineer, this allows the modules to be grouped
into Overlay Groups. These groups allow various Input (master) parameters to be adjusted in all
modules in that group, whist maintaining independent parameter values across each group. This is
achieved in the device by combining the parameters for all the layers for a given section (Gain Delay,
EQ etc.). When an Overlay parameter is active, the Overlay indicator will become illuminated. The
combined Gain or Delay etc. associated with a given section is shown on the module panel in System
Engineer, within square brackets [ ] under the Delay and Gain for each input channel. The combined
EQ curve is shown in an olive color. The Input Mute button in System Engineer will flash if an overlay
mute is active. On the device, the presence of an active overlay is generally indicated by square
brackets “[]” after the parameter value on the display. An input overlay mute is indicated on the
mute/clip indicator for that channel flashing. Note that overlay parameters cannot be adjusted on
the SC48 device itself; these can only be controlled by the System Engineer application. However,
overlay parameters may be removed on the device –see Overlay Flush.
LIR Linear Phase Crossover Filtering
The SC48 also includes a new type of crossover filtering “Linear Impulse Response” (LIR) crossover
filtering, which results in a Linear Phase crossover that has a constant delay regardless of frequency
(unlike other types of crossover which delay different frequencies to a different extent, thus
smearing the arrival time). The LIR crossover can thus be described as having a flat Group Delay
response, and thus entirely free of Group Delay Distortion.
The shape of the LIR crossover filter is quite similar to a 4th order or 24dB/Oct Linkwitz-Riley filter,
and maintains zero phase difference between the adjacent bands across the crossover region to
keep the polar response rock steady.
FIR Linear Phase Equalization
The Input High-Shelf Equalizers use Finite Impulse Response (FIR) filtering to produce Linear Phase
Equalization; that is all frequencies are delayed by the same amount, perfectly preserving the
transient response. This can also be important in applications where different amounts of EQ are
applied to different parts of a loudspeaker cluster, such as to add 'Throw' EQ boost so that parts of
cluster which are throwing further can have HF absorption correction added. If this EQ is not linear
phase, then the zones where the loudspeakers combine may suffer frequency response anomalies.

Audio Connections
Input Connections
For each input channel there is a female XLR input connector. Even channel numbers are for Analog
inputs only. Odd channel numbers are either for Analog inputs (when in Analog input mode) or for
AES3 input pairs (when in AES3 input mode).
The HOT, +, or ‘in polarity’ connection should be made to pin 2 of the XLR connector.
The COLD, -, or ‘out of polarity’ connection should be made to pin 3 of the XLR connector.
Pin 1 of the XLR connectors is internally connected to the chassis. The shield of the input cable
should always be connected Pin 1 of the XLR to ensure that EMC performance and regulations are
met.

Using unbalanced connections
Please note that the use of unbalanced connections is not recommended, however, when
connecting the device to an unbalanced audio source, the signal conductor should be connected to
XLR pin 2. The ‘Cold’ conductor or cable screen should be connected to XLR pin 3 with a short
connection made between pin 1 and pin 3.

Input XLR unbalanced connection
An unbalanced input may be driven by connecting pin-3 ‘cold’ signal to the ground connection of the
unbalanced destination input. The cable shield is connected to pin 1 at the source (this device), and
to ground at the destination device (along with the pin 3 ‘cold’ connection). Alternatively, if the
cable is a single core plus shield, the cable shield should be terminated to both pins 1 and 3.

Menu Buttons- There are three buttons to determine which section of the device to view or edit. The <OUTPUT>
button displays pages of parameters associated with a particular output channel. The <INPUT> button displays pages of
parameters associated with a particular input socket or input DSP channel. Pressing <INPUT> or <OUTPUT> buttons
repeatedly will scroll through the inputs/outputs of the processor. After the last channel, navigation returns to the
Home screen. The <UTILITY> button displays pages of miscellaneous parameters not associated with any particular
channel. Whilst in Edit mode, one of these three buttons will be illuminated. They are mutually exclusive –pressing one
of the buttons will deselect any others that are active. Pressing Utility will escape back to the Home screen.
Page Selection Buttons- When one of the buttons <INPUT>, <OUTPUT> or <UTILITY> is illuminated, the up <> and
down <> arrows will also illuminate, informing the user that these buttons may be used to scroll through the various
pages of parameters that may be viewed and edited. The <ENTER> button is used to confirm an operation such as
storing or recalling a preset or snapshot. It will illuminate when the user is being invited to press it. It will flash when
warning the user that pressing this button will activate an important function.
Input Signal Indicators- A set of five indicators show “Sig”, “-12”, “0dBu”, “+6” and “+12” for each of the DSP inputs
“A” “B” “C” “D”. The signal present Indicators operate at approximately –40 dBu, giving a useful indication of even
relatively low input signal levels. The “0dBu” indicators are intended to show nominal operating level and can also be
useful for setting system gain structure.
Input Clip/mute Indicators - warn the user of input overload and operate at 1dB before clip. The “CLIP” Indicator will
only come on when all other signal lights are illuminated. This indicator also shows a muted input state, and will remain
illuminated at all times whilst mute is active. Input mute is turned on/off in the <INPUT> gain page. This indicator will
also flash regularly if a Module Group has muted this channel.
Graphical Display- When the device is switched on, it will show the Home screen. This provides a useful overview of
channel allocation and Drive Module presets. The screen contrast can be changed by pressing the <UTILITY> button to
navigate to “Screen” and using encoder “A” will change the percentage; this can also optimise the viewing angle. In
most pages the currently selected channel and parameter information is displayed on the upper part of the screen and
the parameter value on the lower part of the screen.
Status Indicators- The “OVERLAY” indicator shows when there are parameters active on a group layer, which the user
cannot access through the front panel of the device (see Overlay Flush). The “NETAUDIO” indicator shows that a
networked digital audio card is installed and routed (Such as Dante™). The “ONLINE” indicator has three states: Off –
the unit is offline and not connected to a computer or network. Flashing- the unit is searching for an IP address; if the
unit does not find an IP address the unit will assign itself an IP address automatically and the indicator will stop
flashing. On- the unit is online and connected with software. IP settings can be viewed or changed within the <UTILITY>
pages.
Parameter Encoders- Three velocity sensitive parameter encoders are used to adjust parameters shown on the
display. Up to three parameters at a time are displayed on the screen. The parameter name is shown above the
parameter value in each of the three screen sections.
AES3 Active Indicators- The “AES3” active indicators show when the AES3 input/output is active for that pair of
channels. AES3 transmits two channels on one XLR cable. Channels 1 and 2 will be carried on connector 1; channels 3
and 4 will be carried on connector 3 and so on.
Mute Buttons- DSP output mute status is indicated and controlled by an illuminated button for each channel. These
buttons flash when the entire unit is muted from the AUX port or from System Engineer Mute-All.
Limiter Indicators- The output indicators show the status of the limiter and output level. The <SIG> indicator shows
signal presence and will illuminate when a signal is present in the output. The second indicator <-6dB> shows that the
signal has reached 6dB below the limiter threshold. The third <LIMIT> indicator indicates that the threshold of that
output channel has been reached. The fourth <+6> indicates a signal 6dB higher than the limiter threshold. The <+6dB>
indicator also refers to the excursion limiter and will illuminate when the threshold of the excursion limiter has been
exceeded. The <˚C> indicator shows that the thermal limiter is active, protecting against long term thermal stress.
Please note that because of the long release time of the thermal limiter, the <˚C> indicator may remain illuminated for
several seconds after signal on that channel is reduced.
Selection Indicators- Each page that is visited when navigating will usually show either one, two or three parameters
labelled “A”, “B”, and “C”below the display, each of which can be edited by turning the encoder associated with that
parameter also labelled “A”, “B”, and “C”below the encoder.

Ethernet Communications Port- The device may be controlled entirely from another controller, typically a Personal
Computer, running an application that is compliant with the ObCom standard such as System Engineer. Connection will
normally be made to the controller via this Ethernet port connector. This port is also used for updating the firmware in
the unit.
Auxiliary Port- The auxiliary port may be configured to recall snapshots or apply muting.
Networked Audio Ports- The DNA SC48 has the option for networked audio ports; if none are required a blanking plate
will be fitted. There are several options for networked audio including Dante™ and AES 67. For a full list please consult
your vendor.
Power Inlet- The Linea Research DNA SC48 unit should be connected to a suitable mains electricity supply using an
earthed IEC C14 connection power lead. The processor has a switch mode power supply that is capable of operating
with a nominal mains voltage of 85V to 240V, 50/60Hz without re-configuration.
NOTE: The DNA SC48 must be earthed to a suitable power earth; failure to do so may affect performance and/or
operation and will invalidate warranty and could be potentially hazardous.
Audio Input Connectors- All audio connections are fully balanced and wired: pin-1 to ground (as required by the AES48
standard), pin-2 hot & pin-3 cold. When AES3 operation is selected on an input pair, the odd channel connector is used
for both channels (e.g. Input 1 is used for channels 1 and 2).
Audio Output Connectors- The processed outputs are impedance balanced, and wired: pin-1 directly bonded to
ground (as required by the AES48 standard), pin-2 hot and pin-3 cold. When AES3 operation is selected on an output
pair, the odd channel connector is used for both channels (e.g. Input 1 is used for channels 1 and 2).

18
Operation
Starting up the unit
The unit will power up as soon as power is applied to the IEC power inlet; there is no power switch.
When power is present the unit will go through its start-up cycle - first all the indicators will
illuminate then go off, while the screen displays the boot loader information. Next the screen will
display the application firmware information, and all the mute buttons will illuminate. The display
will then show the Home screen indicating drive module configurations; the mutes will then return
to the state they were in when the unit was powered off.
Overview of Modules, Presets Components and Snapshots
A Drive Module represents a loudspeaker subsystem, and comprises one input channel and a
number of output channels, associated with one-another by routing. The size of the Drive module is
determined by the number of outputs in it. The device may contain up to four Modules.
DSP Input A
Output 1
Output 2
A Module Preset is a collection of settings (parameters) for a Drive Module of a particular size. The
Preset contains a set of parameters for one input and a set of parameters for each of the outputs in
the module. When a Module Preset is recalled, it will automatically change the routing between
Input DSPs and Outputs, consuming a number of outputs according to the size of the Drive Module.
Recalling a Module Preset thus always creates a Drive Module with consecutive outputs.

Drive Modules
The DNA SC48 uses Drive Modules to represent loudspeaker sub-systems. Drive modules result in a
less processor-centric and more loudspeaker-orientated system design. A drive module is defined as
the processing provided by one Input DSP, and a number of outputs, which are associated with one-
another by means of routing. For example, if Input DSP B is routed to outputs 3 and 4, then this is a
2-way Drive Module; input DSP B forming the ‘master’ control, and output DSP 3 and 4 providing the
driver-related control. The Input DSP parameters then control the Drive Module (and thus the
loudspeaker sub-system). The Drive Module control panel in the System Engineer application is then
used for control and monitoring of this sub-system.
Drive Module Presets
Presets do not change the settings device-wide. Rather, recalling a Module Preset creates a Drive
Module by ‘consuming’ a number of consecutive outputs and setting up routing between the Input
the preset was recalled on and those outputs. The parameters in that Drive Module are then set
according to the parameters in the components in the Module Preset.

Note however, that modules with non-consecutive outputs can be created by manually manipulating
the routing, and then recalling Component Presets to the individual outputs. The resulting system
can then be stored in a Snapshot. Such a Module cannot be saved in a Module Preset.
Note: DSP inputs are not the same as physical inputs. The DNA SC48 has four audio inputs and four
DSP inputs. This is a matrix mixing system where any physical inputs, be they analog, AES3 or
networked audio feeds, can drive any number of DSP inputs.
Component Presets
A Component Preset represents the processing for just one output. Any part of a Module Preset may
be recalled to any one output. A Drive Module comprised of parameters which have been recalled to
its outputs using Component Preset Recalls can then be saved into another Module Preset provided
the outputs remain consecutive (i.e. you have not changed the routing manually). If the routing has
been changed manually, then the whole arrangement may be saved into a Snapshot.Also see
