d:series amplifiers manual
startup air flow and thermal management
2.4 - air flow and thermal management
The d:series unit is a powerful amplifier. Due to the idle loss and the heat arising under heavy working
conditions, it is necessary to cool the circuits adequately. Therefore, the amp is equipped with five fans
with an air flow direction ‘front-to-rear’ and additional air slots for passive convection cooling.
Therefore, it is mandatory to ensure an unrestricted airflow of the cooling system. When mounting the
amplifier in a rack, it is important that cool airflow is provided at the front panel of the amplifier and warm
air can be exhausted from the rear.
We highly recommend to leave 1RU space above and underneath each amplifier in the rack. If the
amplifier was not maintained correctly, all necessary repairs and consequential costs will not be
covered by the warranty.
The system screen on the control surface allows you monitoring relevant temperature states of the amplifier
(see chapter 5.2 ‘system screen’, page 24).
A detailed graphic of the fan curves can be found in chapter 5.6 ‘stealth screen’ (page 37).
Never block the ventilation louvers of the d:series amplifier! Without
sufficient cooling, the amplifier will automatically enter a protection mode
and shut down the power supply for the amplifier modules if necessary.
Don’t place the d:series amplifier near heat sources, like blowers, stoves
or any other heat radiating devices. We also highly recommend not to
place the amplifier directly above or underneath other devices in racks.

startup protection circuitries
2.5 - protection circuitries
Soft-startup
To ensure that the main fuse does not trip if one or more power amplifiers are switched on simultaneously,
the amplifier is equipped with a low inrush circuitry for soft-startup of the system.
To avoid damage of system components such as speakers and the amplifiers electrical components, the
d:series amplifier has got safeguard mechanisms for DC error, overcurrent and over voltage at the
speaker outputs.
Overcurrent protection
To avoid the damage of the amplifier due to short circuit, the output current is limited to 15A per amplifier
channel.
Per-Channel-Error protection
In case of a DC error at the amplifier outputs, the power supply of the affected amplifier channels is being
shut down immediately for security reasons.
In case of defects of an amplifier module, two fine wire fuses will cut the power supply for the affected
module to protect the loudspeakers.
The fuses have to be replaced by sonible. Please contact us for further information.
Overtemperature protection
The d:series amplifier is equipped with three temperature sensors to protect the electrical components
in case of overtemperature. One sensor is located at the end of the cooling tunnel and the other two are
located at the power supplies. If the overall temperature is reaching 90°C for any reason, the protection
shuts down the power supply. The amp modules operated by the affected power supply will be shut down
as well. When the normal operating temperature is reached, the power supply will be activated again.
To avoid thermal shut down, ensure enough airflow and ventilation as described in the previous section
(see chapter 2.4 ‘air flow and thermal management’, page 10).

d:series amplifiers manual
startup responsibility of the user
2.6 - responsibility of the user
Operating voltage
The power amplifier receives its power supply via the mains connector, which is provided as a powerCON
connector.
Depending on the ordered unit, the d:series amplifier supports mains voltage with 100-120 VAC or
220-240 VAC (50-60 Hz). The power supply unit which has an impact on the mains voltage is factory-fitted
and cannot be changed arbitrarily on site.
During installation, always separate the power amplifier from the mains. Connect the power
amplifier only to a mains network which corresponds to the requirements.
The d:series amplifier is delivered with a prefabricated power cord. If you have to change the main
plug for any reason and if you are not 100% confident of your competence to replace the mains
plug, engage qualified personnel to do that job.
In case of questions concerning this matter, please contact sonible via e-mail: [email protected]
Grounding
Your amplifier has to be connected to a grounded socket outlet. Use balanced input connections and
cabling to avoid hum and interference noise.
Dangers at the loudspeaker outputs
The d:series amplifiers are capable of producing dangerously high voltage output that is present at
the output connectors. To protect yourself from electric shock, do not touch non insulated parts of the
speaker cables during operation of the power amplifier.
The external wiring connected to the speaker terminals have to be installed by a qualified instructed
person or ready-made leads or cords of appropriate capacity shall be used.
As the amplifier outputs produce high voltage, do not connect or disconnect speaker cables when the
mains power is on. Also, attach the safety cover on the speaker terminals for safe operation and to comply
with electrical product approvals.
The powerCON is a connector without breaking capacity, i.e. the powerCON must not be connected
or disconnected under load or live.
Speaker system damage
The d:series power amplifiers provide high power output that might be dangerous for human beings
as well as for the connected speaker systems. High output voltages can damage or even destroy the
connected speaker systems, especially, when the d:series amplifier outputs are bridged by the user. Prior
to connecting any loudspeakers, make sure to check the speaker system’s specifications for continuous
and peak power handling capacities.
Maintenance
For safe and reliable operation, the dust filter of the front panel, behind the grilles, can be removed and
cleaned to ensure maximum airflow through the device.
If the dust filter is not maintained when needed there will be safety risks. There is also a risk that the unit
will malfunction since it is dependent on constant airflow from front to rear. If the dust filters are not clean
and the unit malfunctions, any resultant problems will not be covered by the warranty.
A detailed instruction on maintenance work can be found in chapter 8 ‘maintenance & update’ (page 45).
If the amplifier malfunctions due to dirty dust-filters, any required repairs
or resultant drop out costs are not covered by the warranty.

d:series amplifiers manual
connections, pinout and cabling inputs and mains connection
Dante
Dante is a multi-channel digital media networking technology created by Audinate with near-zero latency
and synchronization. By the use of the optional Dante input card the d:series amplifier provides a primary
and secondary port for redundant wiring by a RJ45 connection over gigabit transmission via CAT5e or
higher network cable.
Note: When using the Dante input card the sample rate is set in the Dante Controller software.
MADI (AES10)
The MADI input card is providing two individual MADI inputs and outputs (BNC/coaxial and optical – one
of each type). If needed, both MADI input streams can be used simultaneously and routed or mixed and
merged per channel.
The MADI input option providing one BNC wordclock output, ensuring seamless syncing even in larger
line-ups with other products and brands.
Note: When using the MADI input card, the clock source has to be set in the routing menu via
the touch display or in the web application. The default sync setting of the amplifier is ‘slave’.
Dante | Daisy chaining
For daisy chaining the secondary port can be used. To daisy chain more than two devices we recommend
to connected via Ethernet switches in star network topology. If you are using the secondary port for
redundancy, the relevant devices have to be connected to a second switch.
To be able to set up the Dante network and the routing of the channels it is necessary to install the Dante
Controller which is a software application provided by the company ‘Audinate’. It can be downloaded at
Audinate’s website.
All Dante routing can be configured via 6.5"touch display as described in chapter 5.3 ‘routing screen’
(page 28) or via the remote application (described in chapter 6 ‘remote control, page 38)
MADI | Daisy chaining
The MADI input signals on the BNC and optical connectors are directly patched to the corresponding
MADI output connectors – enabling daisy chaining for several d:series amplifiers without latency.
For wiring of multiple amplifiers within a rack, suitable coaxial cables (RG59, 75 ohm) or optical wires are
recommended.

connections, pinout and cabling outputs and bridging
4.3 - outputs (euroblock)
speaker outputs
4.4 - bridging
The d:series amplifier is supplied with 2-pin Euroblock connectors for each amplified output channel.
Compatible plug connectors are part of the delivery. To guarantee the operating safety and the proper
function, sonible recommends to use only prebuilt or professionally built speaker cables with minimum
cable cross-sections of 1.5mm2.
The amplifier offers to bridge channels in pairs of two. The main benefit of bridging is a doubling of output
voltage. Therefor you have to route one input signal to two amplifier channels, whereas one amplifier
channel is fed by the original signal and the other channel with the phase reversed counterpart. When
using digital inputs, the following steps have to be performed:
Step 1:
When using bridged mode, the same input source
has to be routed to both output channels in the
routing menu (e.g. input channel 1 to output
channels 1+2). The second input channel has to
be phase inverted in the routing sub menu of the
amplifier as shown in the graphic.
Further information about routing can be found in
chapter 5.3 ‘routing screen’ (page 28).
Step 2:
The 2-pin output speaker cable has to be connected with one pin to the plus
pole of the first channel (1+) and with the second pin the plus pole of the
second channel (2+) as shown in the graphic on the left.
If analog inputs are used for bridging amplifier channels you have to ensure
that the input signals comply similar to the description mentioned above. That
means that one amplifier channel has to be fed with the original signal, the
other with the inversed counterpart. The phase inversion of the input has to be
performed beyond the amplifier.
NOTE: Please be VERY careful when bridging channels! Incorrect
wiring can damage the corresponding amplifier channels as well as the
connected speaker. The bridged loudspeaker may not be connected to
the ground under no circumstances.

The d:series amplifier offers remote control via an Ethernet connection. To establish a connection, the
remote device (e.g. Laptop) has to be wired to the ‘network’-port at the rear of the d:series amplifier.
Remote control for multiple devices:
To access a remote control for multiple amplifiers
in a network a star topology via Ethernet switch is
needed.
The instructions to configure the network
connection via the touch screen can be found in
chapter 5.4 ‘network screen’ (page 32).
A detailed description concerning the estab-
lishment of a connection between the amplifier
and the remote device can be found in chapter 6.1
‘establishing a connection’ (page 38).
Remote control via wireless connection:
The d:series amplifier can also be remote controlled via a wireless connection by using a wireless access
point. To guarantee an impeccable functionality we recommend to use a wired connection. The web
interface is optimized for remote control via laptop or desktop computer.
