Page 9: Thanks And Unpacking
Thanks and Unpacking Thank you for choosing a Danley Sound Labs DNA SC48 advanced system controller for your application. Please spare a little time to study the contents of this manual, so that you obtain the best possible performance from this unit. -
Page 10: Installation Instructions
INSTALLATION INSTRUCTIONS THIS PRODUCT MUST BE EARTHED. Use only a flexible cable or cord provided with a green or green and yellow core which must be connected to the protective earthing terminal of a suitable mains plug or the earthing terminal of the installation. The cord must be of maximum length 7.5 meters, rated SJ, SJT, or SJE, 10A minimum and be marked VW-1. -
Page 11: The User Guide
This user manual gives a progressively more detailed description of the functions of the Danley Sound Labs DNA SC48 series advanced system controller. A single page quick reference guide is provided for those users who are experienced with this type of equipment and just need to know how to ‘drive’... -
Page 12: Introduction And Key Features
High performance ‘universal mains’ switch mode power supply, designed in-house 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;... - Page 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.

Page 14: Audio Connections
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’... -
Page 15: Using Unbalanced Connections
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. -
Page 16: Panel Layouts
Panel Layouts 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. - Page 17 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.

Page 18: Operation
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. -
Page 19: Drive Modules
Output 8 component number 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. - Page 20 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.

Page 21: Navigation And Designing Crossovers
Navigation and Designing Crossovers The DNA SC48 has 50 Drive Module preset locations. These can be stored and recalled from the <INPUT> pages, for the channel being viewed. To design a new crossover, press the desired <INPUT> or <OUTPUT> button to enter the pages where the parameters for each of the channels are shown. -
Page 22: Storing Module Presets
Storing Module Presets Once a drive module has been created it can be stored by pressing the <INPUT> button until the edited channel is reached, then pressing the down <> button until store page is reached. Using encoder “A” will change the preset number. When the destination preset is reached, pressing the <ENTER>... -
Page 23: Input
Also see Snapshots. Input AES3 / Network Inputs In addition to the usual analog inputs, the SC48 can also accept AES3 digital inputs. The same physical XLR sockets are used for both Analog and AES3 inputs; the function of these being determined by the Source parameters in the Input Route menu. -
Page 24: Gain And Polarity
Gain and Polarity The gain page of the input channel selected allows users to increase or decrease the amount of signal going into the selected input. Using encoder “A” will change the value in 0.2dB steps from -40dB to +20dB. The presence of an active Group Overlay parameter is indicated by the ‘[]’ symbol (See Overlays). -
Page 25: Routing
controlled by encoder “B” and ranges from 0.10 octaves to 5.2 octaves. Bandwidth can be shown and adjusted as Q or Octaves (Oct). Gain is controlled by encoder “C” and is adjusted in 0.2dB increments. The presence of an active Group Overlay parameter is indicated by the ‘[]’ symbol being appended to the Gain value. -
Page 26: Lir Crossover Filtering
Utilities. Limiters The DNA SC48 includes three limiters in the output signal path. Please note that whilst the Limiters in this product offer protection for amplifiers and drivers, they can never protect from all possible scenarios, therefore Danley Sound Labs is not responsible for any damage which might occur. - Page 27 When VX mode is engaged, the user can choose the crossover point of a ‘virtual crossover’, which incorporates two limiters per output so the user can individually limit the drivers in a passive 2-way enclosure using individual thresholds, and optimised attack and release characteristics for each. The Threshold of the second ‘Hi’...

Page 28: Amplifier Gain
A further parameter “Min” may also be available for more advanced applications. This allows the increasing limiting action at lower frequencies to level-off below a certain frequency. In most application, this would be left set to its default value of 5Hz. Amplifier Gain Expressed in dB, this is the gain of the amplifier which the output of the SC48 is feeding. -

Page 30: Static-Ip
Static-IP If the device or the computer has a static IP address set, System Engineer may not be able to 'see' the device if it is in a different IP Address range (i.e. in a different subnet). Unless there are good reasons it is best to avoid the use of static IP addressing if at all possible. - Page 31 • None - No operation 2+Mute (Event or State) – Either Snapshot 1 or Snapshot 2 may be recalled by applying a • momentary or static connection to an Aux port terminal, or the device may be muted by Grounding both Aux port terminals 3 Snaps (Event or State) –...

Page 33: Latency Delay
Latency delay All Digital Signal Processing, and conversion between different formats of signal – analog/digital/network etc, necessarily introduce some delay (latency) to the signal path. Of course, we strive to minimise these latencies. Small as they are, it is sometimes useful to know their precise values. -
Page 34: Secure Mode
Example: Input/Output Analog Input 0.385ms Analog Output 0.402ms Processing Input HiShelf FIR (Off) LIR Linear Phase crossover (500Hz) 2.38ms VxLim Lim (VX mode on, 1KHz Fsplit) 0.358ms Total 3.525ms Note that the latencies within a Drive Module are equalised among outputs of that Drive Module. That is, padding delay will be automatically added to some outputs such that the total latency is the same in each output of a Drive Module. -
