Introduction
SourceCon™ Bluetooth receiver module
The BMP42 is a professional Bluetooth receiver module 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 conguration.
The BMP42 receiver offers wireless connection possibilities for audio playback from any Bluetooth compatible portable device
including laptops, smartphones, tablets or any other. Long-range transmission distance (up to 30 meters in an unobstructed open
area) is possible depending on the installed environment. Device discovery and pairing protection with a storage up to 8 authorized
devices shall prevent playback from unauthorized users in public area’s.
All media information such as track and artist information can be retrieved from the BMP42 (if supported by the connected device,
more info on P15: technical specications), while playback control is possible from the connected device or remote control.
The antenna input is implemented by an SMA-type (50 Ω) connector on its panel, allowing connection of the included (2 dBi)
antenna while extension is possible in situations where its installed in a closed / shielded cabinet. The balanced stereo line output
is connected through two 3-pin terminal block connections.

Overview BMP42
The BMP42 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 the panel.
1) 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 amplier or pre-amplier.
2) SMA-type antenna connection:
The antenna (input) connection is implemented using an SMA-type (male) connector whereto the supplied antenna should
get connected. Depending of the installation conditions (e.g. when installed in a closed / shielded cabinet), it can be extended
using optional available accessories for optimal reception conditions.
3) Connection external pairing contacts:
When the BMP42 is installed in a device located in something
like a locked rack, it may be difcult to enable Bluetooth pairing
for new devices. For this purpose, an external pairing connector
can be connected that contains the combination LED and button.
When the button is pressed, Bluetooth pairing is enabled. This is
conrmed by the ashing of the LED.
If a device was connected, the connection is broken. The LED will
icker for 60 seconds and the BMP42 is visible to make a (new)
connection. If a device connects, the LED will remain lit. After 60
seconds without connection, the BMP42 is no longer visible to
new devices but old devices can still connect. After 60 seconds
the LED will be off.
The connection can be made according to this wiring diagram:

Using the BMP42
Module screen
Since the BMP42 is a SourceCon™ module, it can be combined with a variation of supporting main units. The operating and
conguration interface may differ depending on the device it is installed on, but the functionality offered is the same. Some
devices will support control and conguration through a front panel graphical control interface on a display, while others are
also supporting web-control.
This manual describes the control and conguration possibilities via a front-panel graphical control interface display. For
applications with more control possibilities, refer to the user manual of the main device used for further instructions.
Player:
The (player) button gets you to the player mode screen where track information is displayed (if supported by the connected
transmitter) and previous or next audio track selection can be done.
Home:
The (home) button gets you back to the main screen of the device where the BMP42 is installed to.

Connecting:
The main module screen of the BMP42 indicates the connection
status of the receiver. To avoid audio playback by unauthorized users
in public installations, transmitter and receiver pairing is required when
connecting for the rst time.
The receiver cannot be discovered from the transmitting device
unless the receiving and transmitting devices have been previously
paired. In this case, press the button to make it discoverable.
Once connected, the main module screen displays the name of
the connected device and it will become undiscoverable for other
devices.
Once both transmitter and receiver have been paired, the receiver
will remain connectable for that particular transmitter, even when the
connection button hasn’t been pressed. The BMP42 memory
stores up to 8 authorized device ID’s.
When the button is pushed, the connection with the current device
is broken and the BMP42 becomes discoverable again.

Player mode
Track selection:
The playing track can be selected by pressing the (previous track) and (next track) buttons. When selected, the rst
next supported track will be selected and start playing.
Play / pause:
Toggling between play and pause is done by pressing the play/pause button with (play) or (pause) symbols. Depending
on the current mode, the displayed symbol on the icon will toggle.
Return:
The (return) button gets you back to the main module screen of the BMP42.
In this screen, all available media information about the currently
playing les is shown including track, artist or any other information,
while previous and next audio track selection can be done.
Note that the displayed information in this screen depends on the
supported functions of the connected transmitter.

Various adjustments can be made on the BMP42 using our simplied design and control platform - AUDAC Touch™.
AUDAC Touch™ is available for free on the Apple App store,Touch™ app can be downloaded from the Apple App store,
Google play store or audac.eu/eu/software/ audac-touch.
The BMP42 is visible on the overview page of the parent device in the Audac Touch™ platform.
Select the BMP42 to make adjustments.
Gain:
The gain is synchronized from the device connected to the BMP42. If it is not to the desired level, it can be adjusted on the
BMP42. The gain can be adjusted within a range of 0 dB and -82 dB, allowing optimization of the output level according to
the input sensitivity of the connected amplier or pre-amplier.
Advanced settings - Factory reset:
Factory reset will recall all settings to factory defaults and all previously made settings and congurations will be lost. After
selecting factory reset, a conrmation will be asked whether all settings denitely need to be reset to factory defaults. When
conrmed, all settings will be lost.

module screen)
Devices can be removed from this list by pressing the delete icon.
When the ‘Pair new device’ button is used, the receiver is discoverable and allows connection for about 60 seconds from
any transmitting device.

BMP42 - User manual 013
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.
Chapter 5
Installing the BMP42
CAUTION
Before installing the BMP42 to any SourceCon™ compatible device, make sure the power is switched off.
Malfunctions or electrical shocks may occur otherwise.

BMP42 - User manual014
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 correctly installed, the system can be powered-on and the module functionality will be automatically
discovered.
