Introduction
SourceCon™ DAB/DAB+ & FM tuner module
The DMP42 is a professional DAB/DAB+ & FM tuner 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 DMP42 provides access to a wide variation of radio stations while guaranteeing a high quality audio reproduction. Station
selection can be done manually or automatically, while up to 10 preferred channels can be internally stored and recalled.
Radio station information carried by RDS / Radiotext can be retrieved, while other functions such as mono/stereo switching
(FM) always guarantee the best possible audio clarity.
The signal output level is user congurable, while dynamic range compression (DRC) is supported, improving the intelligibility
for low volumes in applications with high levels of background noise. Signal reception strength can be retrieved from the
module and indicated on the graphical interface of the controlling device.
The antenna input is implemented by an F-type connector on its panel, allowing connection of the included antenna cable
or any other external antenna using 75 Ωcoaxial cabling. The balanced stereo line output is connected through two 3-pin
terminal block connections.

Output gain;
The gain can be adjusted within a range of +8 dB and -32
dB, allowing optimization of the output level according to the
input sensitivity of the connected amplier or pre-amplier.
For adjusting the output gain, rotate the function dial until
‘Gain’ is highlighted and press it for proceeding to the gain
settings. The level can be adjusted by rotating clockwise
(tuning up) or counter-clockwise (tuning down). Press the
rotary dial for conrming the currently set output level.
Mono:
The FM reception is standard set to stereo mode, however it will switch automatically to mono mode if the signal reception
strength is insufcient. This reduces the noise and improves the sound quality when having poor signal reception.
Manual switching the output to mono mode is possible using this function, allowing the output to be fed to mono systems,
such as 100V public address ampliers. Toggling between mono and stereo mode can be done by single pressing the
function dial.
DAB DRC:
The DRC (Dynamic Range Compression) increases the loudness of the signal in the quieter parts of the audio signal and
decreases it in the louder parts. This technique allows quieter parts of the audio signal still being audible in situations with
high background noise without blasting out. It can be switched between Off, Low and High. DRC data is carried by an
additional side channel of DAB radio station and is only functional when the selected radio station carries the DRC data.
DAB info:
Gives additional information about the currently playing DAB radio station. Displayed information includes station name,
currently playing program or track name, signal reception strength, bitrate, ...

Installing the DMP42
015
NOTE
Before installing the DMP42 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 where to 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.

DMP42 - User manual016
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.
