Using the MMP40

Since the MMP40 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 MMP40 gives an
overview of the current operation mode and can
be switched between media player mode and
media recorder mode. In media player mode,

Media recorder settings

The recorder settings menu for MMP40 is loaded when pressing the (settings) button
in recorder mode.

Filename:

The filename of the recorded tracks can be
configured in this screen. When selected, a
screen with keyboard overview allows to enter
the filename through using the rotary selection
dial. When entered, select ‘OK’ to confirm the
currently entered track name. ‘Delete’ removes
the latest entered character, while ‘Cancel’
brings you back to the settings overview screen
without any applied changes.

When making multiple recordings in a row, each audio recording will be stored as an
individual file (when the recording was stopped). When the filename is not changed in
between various recordings, the subsequent recordings will be indicated with a number
(e.g. recording(2).mp3) in the stored filename.

Filetype:

The filetype of the recordings can be selected between MP3, OGG Vorbis and Wav. Toggle
between the various recording filetypes by highlighting ‘Filetype’ (navigate through rotary
dial) and pressing the rotary dial.

OGG Vorbis

Mono/stereo:

The recording for MP3 filetypes can be switched in various types of mono / stereo
modes, including ‘Joint stereo’, ‘Dual stereo’, ‘ Mono (left input)’ and ‘Mono mix’.
Toggle between various recording modes by highlighting ‘Mono / stereo’ and (navigate
through rotary dial) and pressing the rotary dial.

Using ‘Joint stereo’ mode, the similarities and differences between both left and right
channels are individually encoded. This improves the compression efficiency at a slight
loss of separation.

Using ‘Dual stereo’, both left and right channels are individually encoded as completely
separate signals. Each channel uses half of the available bitrate, for example by a 128
kbit recording, each channel would take 64 kbit.

15

Using ‘Mono (left input)’, only the signal available on the left recording input will be
recorded as a single (mono) audio signal.

Using ‘Mono mix’, both left and right signal inputs will be summed to a mono signal,
which will be recorded as a single (mono) audio signal.

MP3:
The MP3 recording settings can be selected between ‘Variable bitrate’ and ‘Constant
bitrate’. In constant bit rate mode, a fixed bitrate is used for the entire track resulting

in consistent and predictable file sizes. In variable bitrate mode, the bitrate is adapted
according to the complexity of the audio. For simple passages, the system automatically
turns the bitrate down, saving valuable data bits while retaining audio quality. During more
complex passages, the system automatically turns the bitrate up, using more databits to
retain the same level of audio quality. In general, the variable bitrate gives better results
in terms of audio quality, while the constant bitrate is better for compatibility (mainly
with older systems).

The bitrate for the audio recording can be selected between 64 kbps, 96 kbps, 128
kbps, 192 kbps, 256 kbps and 320 kbps. A bitrate of 192 kbps is generally accepted
as good-quality, while a 256 kbps recording corresponds with CD quality. For constant
bitrate recordings, the selected bitrate is constant throughout the entire track, while for
variable bitrate recordings the nominal bitrate is defined, which could be influenced by
the complexity and detail of the audio.

OGG Vorbis:

For OGG Vorbis recordings, the quality settings can be selected by a number from ‘0’
to ‘9’, whereby ‘0’ corresponds with a nominal bitrate of 64 kbps and ‘9’ corresponds
with a nominal bitrate if 320 kbps. Starting from ‘6’ (192 kbps) the recording is generally
accepted as a good-quality recording, while ‘8’ (256 kbps) corresponds with CD quality.
An OGG recording provides the same quality for a lower filesize, compared to MP3.

WAV:

For WAV recodings, the sampling rate can be selected between 8 kHz, 16 kHz, 24 kHz, 32
kHz and 48 kHz with a fixed bit depth of 16 bits per sample. Depending on the application,
the suitable sample rate can be selected. For high-quality music recordings, it is
recommended to always select the 48 kHz sample rate, while for voice announcements
or other spoken message recordings, lower sample rates can be sufficient.

Installing the MMP40

CAUTION

Before installing the MMP40 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.

17

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.
