Reprogramming of dp-speakers with preset audio files
By default, the built-in DSP controller is in a default configuration state that conforms to the descrip-
tion in the User Manual. The installation of special presets on the DSP controller can be done by
the user himself, since only a special preset audio file must be loaded. The programming of these
audio files via the LPI (Loudspeaker Programming Interface) can only be done by the manufactur-
er.
The preset is getting installed on the DSP by playing the preset audio file in the XLR input. This can
be done in different ways (MP3 player, smart phone, PC, CD player, ...). Installation via PC is done
as follows:
1. Use a mini-jack-XLR (stereo) cable to connect the headphone output to the XLR input of
the self-powered box. Use only one of the XLR connectors.
2. Mute the box by pressing the Set button in Status Mode. The Mute LED lights up. The DSP
controller can only receive data in the muted state.
3. Make sure your computer's volume is set to 100%.
4. Load the ".wav" file received from SEEBURG acoustic line into a music player.
5. Press the play button.
6. After a successful programming operation, the Mute LED turns off.
It is very important to ensure that the preset audio file is played in
single mode. Other music files in the playlist or on the data storage
medium will otherwise be played at full volume.
