nounce: “NO SOURCES AVAILABLE”
Once an audio device has been connected, the unit will pronounce:
“PLAYING FROM IPOD / USB / AUX IN” and the playing will start.
The same message is pronounced at the switching on, if a device is already connected to MAE-
STRO 2.0 .
If the user doesn’t connect any devices to MAESTRO 2.0 , the unit will switch off after 30
seconds and it will pronounce “GOODBYE”
All functions handled by MAESTRO 2.0 are also written in English on the display.
Menu headings and files titles contained into the audio sources are displayed thanks to MAE-

case of OEM radio, they are visualized also on the vehicle display (if the OEM radio can write
also on this one).
The displayed menu headings are the same for all the languages and they are set by default in
English. Instead, for what concerning files titles, MAESTRO 2.0 controls the information deriving
from the mp3 TAG: if the TAG is present the unit displays up to a maximum of 64 characters; if it
is not available, MAESTRO 2.0 will display the file name but up to a maximum of 64 characters!
Folders name are displayed on the display too; also in this case, MAESTRO 2.0 displays only the
first 64 characters, so it’s advisable to name the folders with maximum of 64 characters.

AUDIO QUALITY
MAESTRO 2.0 is able to handle the audio files with a re production quality similar to the CD one.
To have this result, the user must use excellent quality audio files.
About the iPod, MAESTRO 2.0 respects the audio levels decided by Apple; this means that the
user will have a perfect listening result only if the tracks have been elaborated by iTunes.
In case of a low quality file, it should happen some distortions (if the recording volume is too high)
or some worsening about the ratio between the signal and the noise (if the recording volume is
too low).
About the USB, MAESTRO 2.0 respects the audio levels decided by Paser; this means that the
user will have a perfect listening result only if the track have been regulated according to an AU-
DIO LEVEL, by using the free software called MP3GAIN, available on the web site www.paser.it.
Please regulate the audio level at 89.0dB
About the track of different origin, the quality is good, even if the user can find some differences
about the volume among the playing of a file and another.
In case of a low quality file, it should happen some distortions (if the recording volume is too high)
or some worsening about the ratio between the signal and the noise (if the recording volume is
too low).
About the JACK AUX IN input, it’s possible to regulate the audio quality directly from the device
that the user will connect.
Paser can’t guarantee that all available USB pens will be compatible with MAESTRO 2.0 .
In the case that the module cannot recognize a USB pen, please format it in FAT32 and try
again.
