The NMP40 is a professional network audio player featuring SourceCon™ modular
technology. This unique technology guarantees true plug & play implementation to any
compatible device. When inserted to a supporting slot, the module is instantly installed,
discovered and ready for operation without requiring any additional internal wiring or
complex configuration.
The NMP40 SourceCon™ network audio player enables the possibility to stream audio
files from a personal computer or mobile device directly to a professional audio system
while maintaining the best available sound quality.
Through Spotify Connect, you’re able to stream music straight to your professional audio
system directly from the cloud while using your computer or mobile device only as a
controller. This avoids any unwanted interruptions and maintains higher sample rates.
The balanced stereo line output is implemented on its panel using two 3-pin terminal
block connections.

Overview NMP40
The NMP40 is a SourceCon™ compatible module featuring an (internal) board-edge
connector which carries all signals for getting it connected to any supporting main unit.
All external in & output connections shall be made using the available connectors on

Balanced stereo line output:
The balanced stereo line output is implemented using two 3-pin terminal block
connectors. The audio output available on this connector allows it to be fed to any
amplifier or pre-amplifier.

Chapter 3
Installing the NMP40
CAUTION
Before installing the NMP40 to any SourceCon™ compatible device,
make sure the power is switched off. Malfunctions or electrical shocks
may occur otherwise.
Step 1:
Make sure that the slot whereto the module should be installed is open and ready for
installation. Depending of the main unit, some module slots will be covered by blind
panels when delivered. The corresponding blind panels should be removed by releasing
the screws on both ends.
Step 2:
Before removing the modules from their protective bag, we recommend touching a
grounded metal chassis (or any other grounded point) to prevent electrostatic discharges
affecting the sensitive electronic components. It is recommended to always hold the
module card by the metal connection panel and avoid touching of the components on
the circuit board directly.
Step 3:
Align both edges of the module with the guide rails inside the slot and carefully insert
the module into the slot. It should slide into the slot without any considerable resistance
when well positioned into the guide rail.

10
Step 4:
Some resistance might occur when the module’s board edge connector reaches the
connection counterpart on the main board. Gently push the module all the way into the
slot to ensure that the contacts are correctly inserted. The module is well inserted when
its connection panel touches the metal chassis of the main device where inserted to.
Step 5:
Fasten the module into the slot using the included screws. Be aware that damage or
malfunctions may occur if the module is not correctly fastened.
Step 6:
Once the module is correctly installed, the system can be powered-on and the module
functionality will be automatically discovered.

Chapter 4
Using the NMP40
Since the NMP40 is a SourceCon™ module, it can be combined with a variation of
supporting main units. The operation and configuration interface might be different of
the unit where installed, however the offered functionality is identical. Some devices
will support control and configuration through a front panel graphical control interface
on a display, while others are also supporting web-control.
This manual describes the control configuration possibilities using front panel control. For
applications where more control possibilities are offered, check the instruction manual
of the used main device for more instructions.
Module screen
The module screen of the NMP40 gives an
overview of the currently playing track, and
can be used to play and pauze the music and
to select the next or previous track.
The left section of the module screen includes 4
quick buttons which can be controlled through
the tactile buttons on the left screen side.
