File Format
The Waveplayer is using the multi hannel wav format. All tra ks are saved in one file. This is very
omfortable, be ause you don't need to handle a lot of mono files. Some audio software will be able
to reate multi hannel files. But the re ommend software to be used for this task is the freeware
„Auda ity“. Why? It is free, well tested with Waveplayer and it is simple to do.
Here a very brief instru tion:
1. Start the software.
2. Create as many tra ks as you need (1-8).
3. Fill the tra ks with you ontent.
4. Export you work into a file (WAV PCM , 16 or 24 bit)
5. Done!
Note: There is a very important setting edit->preferen es->import/export. This has to be set to
„ ustom mix“. If this is not done, you will get stereo or mono files all the time.
SD Cards
Cards of any size an be used. The only requirement is to format the ard to FAT/FAT32 with the
minimal luster size of 32kB. Cards bigger than 32GB will be supplied with exFAT and have to be
reformatted to FAT32. This is not possible under Windows. You will need a spe ial tool for that.
For example: Fat32 Format
Playing Parameter
Waveplayer is playing wav files from 1-8 hannels in 16bit or 24 bit.
The supported sample frequen ies are 32kHz, 44,1kHz and 48kHz.
Main and Channel Volume Settings
By repeatedly pressing the „Play“ button, while the devi e is playing a file, you an a ess the main
and hannel volume settings. You an go ba kward by pressing the „Pause“ button, if you want to
go ba k to other parameters in the list. The „+“ and „−“ button will hange the volume in stages of
0.5dB. The individual settings are saved when hanging to the the next („Play“) or to the last
(„Pause“) parameter.

Configuration Menu
By pressing the „Menu“ button you will rea h the onfigurations menu. The „+“ or „−“ button will
hange the available parameter. If you want to hange a parameter press „Play“. Now you are in the
edit mode. The ursor is blinking. Change the parameter with the „+“ or „−“ button. You an save
the setting by pressing the „Play“ button. Press „Stop“ to dis ard the hanges.

Start Mode
• Manual → Songs will be played by hand
• Auto → If this parameter is set to on, the Waveplayer will automati ally start to play after
power is on. There is a requirement to make this fun tion work orre tly. We need a
playable song at position 1. What is position 1? After the Waveplayer is swit hed on it will
sort through all files of the root dire tory alphabeti ally and will display the first. This is the
file in position 1. If this file not playable auto play will do nothing!
• Time ode → If a valid time ode is re eived the player will start playing automati ally.
If the time ode is missing for more than 5s the player will stop.

Play Mode
• Single Play → is playing one file from start to end .
• Continuous Play → is playing all playable files of the folder and stops. Non-playable files
will be skipped.
• Random Play → is playing the files randomly. In this mode only playable files are allowed
to be in the folder.
• Song Loop → is playing the same file repeatedly.
• Album Loop → is the same as Continuous Play, but with repeating.
Baud Rate Serial
The baud rate setting is relevant only if the serial proto ol via RS232 is used. Values between 1200
and 256000 baud are possible.
Data Port Mode
The normal setting for using a single devi e is „standard“.
If you plan to use more than one devi e than both modes are of interest.
In „standard“ mode the Waveplayer responds only to ommands whi h have the same ID.
Commands whi h have not the same ID will be forward to the next devi e. Commands with the
ID=255 are broad asts and will be responded and forwarded to the next devi e in the hain.
In „bus master“ mode the buttons „Stop, Pause, Play“ will be forwarded via broad ast to the other
devi es. This way you an use more than one devi e via one keypad. When „Start Mode“ is „auto“
then the devi e will simulate a play ommand, at power on, to start all other onne ted devi es too.
In „Play Mode“ „song loop“ a play ommand will be send at start of every new loop y le to resyn
the other devi es. In „bus master“ mode no telegrams will be forwarded.
Device ID
If you plan to use the data port of the Waveplayer this ID ould be of interest. You an set this value
from 0 to 255. If the se ond parameter of a ommand mat hes the devi e ID, the ommand will be
exe uted and you will get an answer. Note: The 255 is the broad ast ID of all devi es. All devi es
will exe ute this ommand but never get a response.
LCD contrast
Set the ontrast of the LCD display.
LTC Timecode
The devi e has a LTC time ode input and output. The output displays the urrent play time of the
running tra k. The time ode is using a 25f/s format. The time ode input is permanently a tive. Is a
valid signal on the input dete ted, the urrent playtime will fit to the input time. If you want to use
the time ode input, the datas on ard must not be fragmented!

*) This ommand will get a response 0x84 only if a CRC error o urs.
**) This means the error of a forwarded answer.

CRC Calculation
The CRC is al ulates all bytes of the message, whereas the CRC itself is 0. The result of this
al ulation has to be the repla ement for the initial CRC value (0) before sending. To he k if the
message is valid at the other side, al ulate the CRC for the whole message. If the result is zero the
message is valid.
Software Update
1. Copy the file with the name „wp3image.bin“ to a SD ard.
2. Insert the ard in a running devi e.
3. If more than one file on ard use the +- keys and go to the file.
4. The player will re ognize the update and offer to press „Play“.
5. After starting the update pro edure you will see „Burning done!“ after a few se onds.
Additionally the info how mu h pages are burned.
6. Restart the devi e and the update is finished.
Connections
• 8x audio out (unbalan ed, 0dBu maximum Level, 10kOhm output resistan e)
• LTC tim ode in/out
• Data port for RS232 proto ol
