Description
The NanoPlayer box delivers WAV/MP3 audio content automatically upon the switching on of the player (autoplay), interactively via an input contact or via the infrared remote control.
From a small size, the NanoPlayer box gets settled in various contexts. The audio files are stored on a SD card and organised simply, with a file manager. The naming and the structure of the audio files define their playback.
The double amplifier allows the connection of two headsets or two audio solutions MonoEarphone ID-AL©. The NanoPlayer box features a 2×8 W amplifier in order to connect two passives speakers.
The interactivity of the NanoPlayer box resides in the trigger of the audio files with an input contact via a push button, a motion sensor or any other electric event. The trigger and the change of the playback as well as the volume setting can also be managed by the infrared remote control (in option).
Ideal to bring an audio perspective into any spaces, in money-saving installations, to spread messages to an audience or to install a sound system in public spaces, the NanoPlayer box is a versatile and cost-effective audio solution.

- The WAV file I created with Protools makes an odd noise each time it starts up.
WAV files created with Protools as well as with certain types of audio software are not standard WAV files. These are WAV Broadcast files which contain ‘metadata’ as well as the standard audio data. The player plays the ‘metadata’ zones in the same way as the audio data, which causes an odd noise at the start of the file reading. To resolve this problem, you can make your WAV files conform by taking out all ‘metadata’ so that only audio data useful to the player is kept. If you do not possess the necessary audio editor to carry out this operation, you can make a copy of your audio file using the software Audacity. This software is under a GPL licence and is free to use whatever your operating system (Windows, Mac OS X or Linux).
-
- Some MP3 files are not correctly play by my player.
At first make sure that the audio file characteristics are same as the specifications of your player (bit rate, number of channels, resolution, encoding types). If everything looks correct, make sure that all metadata (TAG ID3v1 and ID3v2) of your MP3 file is deleted to keep only useful audio data. Some types of TAGs can prevent to playing the file. There are many utilities to manage and remove tags of your files, but if you do not have a reference application, you can use Winamp (Windows) software.
-
- I carefully followed the instructions to naming files and folders explained in the manual but the files and folders do not seem to follow the desired logic.
The problem probably comes from the names of files and folders that you used. Names of files and folders use three characters, neither more nor less. Each character must make a sense according to the user manual and be entered in uppercase. Otherwise, the player apply the default function.
-
- Can I use a Mac OS X system to prepare the contents of my SD card or USB flash drive?
When using a Mac OS, the hidden system (. DS_Store, etc.) files generated by this system and which interfere with the proper operation of your player must be deleted manually:
-
-
- On the MAC computer, insert the storage device.
- Format the storage device as FAT 32 and give it a volume name.
- Store on it useful files according to the organization demanded by the player.
- In the terminal of MAC OS X (folder « Applications » -> « Tools »), enter and execute the following command: dot_clean -m /Volumes/(volume name)
- Eject the storage device with the ejecting process of the system.
- Turn the player on with the storage device prepared as follow.
-
- I don’t know how my file is encoded. Which software can i use to know precisely which are the caracteristics of my file? (format, type, encoding, bitrate…)
If you have not any software for this, you can use MediaInfo software (http://mediaarea.net/fr/MediaInfo). This software, provided under BSD license, is free and opensource on all operating system (Windows, Mac OS X or Linux).
-
- I hear drop in the sound when I read some MP3 files. What is the problem?
With some audio players of the « NanoPlayer » range of products, your MP3 files must not be encoded more than 128 kbps. This is sufficient in the large majority of uses. It is not recommended to use files encoded at 192kbps, 256 kbps or 320 kbps. If you need a higher quality 128 kbps, use the WAV format instead of the MP3 format.
