•Introduction
Thank you for purchasing the DL-11 Digital MP3 Audio Player. The
DL-11 is an easy to use, reliable audio source, for all Promotion-On-Hold
applications. The unit is shipped with a demonstration MP3 audio file stored
on the Flash Drive named "Generic.mp3". The DL-11 will automatically
start playing the MP3 file when it is connected to power. When it gets to the
end, it will immediately re-play the file. It repeats this over and over again to
supply constant audio. If you should loose power, the DL-11 will
automatically re-start, from the beginning when power is re-stored. The DL-
11 plays the audio directly from the USB Flash drive, so there is no initial
LOAD sequence on power up. The unit has a built in 200 milliwatt audio
power amplifier so it has plenty of power for all telecommunication
applications. DO NOT use the headphone jack next to the USB Drive as your
audio output. The RCA Audio Output, on the front panel of the unit, is the
only output that should be used. It has been design to work with both 8 ohm
and 600 ohm inputs. The DL-11 has a 64 step user adjustable volume
control. To change the VOLUME you must tap the UP or DOWN buttons.
The preset volume is maintained even through power outages. If a stereo
MP3 file is used, audio is taken from the LEFT channel on the file. The DL-
11 also comes with an internal TEST speaker so that you can easily test to
see if your DL-11 is playing properly. The DL-11 is very versatile. It can be
used as either a single message system, or as a multi-message system. The
maximum audio playback length for an individual production is 1 hour.
•Updating the Audio Program
The first step is to get a new MP3 audio file to the end-user. Small MP3
files, less then 9 minutes in length, can usually be emailed to the end-user. If
needed, you can use a 3rd party site such as "YouSendIt.com" to transfer
larger MP3 files.
Once the MP3 file is on the end-user's computer, the Flash Drive must
be removed from the DL-11, then inserted into a USB port on a computer.
The old MP3 file must be deleted, then the new MP3 file can be copied to
the Flash Drive. There are detailed "Drag & Drop" instructions for Windows,
with pictures, on our web site at www.skutchelectronics.com/dl-11.asp.
Make sure that you use the "Safely Remove Hardware" icon (Shown on top
of next page) before removing the Flash Drive from your computer. This will
prevent data corruption on the Flash Drive.
•Multi-Messaging
You can store up to 20, six minute audio productions on the 128MB
flash drive. The DL-11 allows you to easily switch between these messages.
The first step is to store multiple MP3 files on the Flash Drive. This must be
done from an external computer. Once the files are stored, put the Flash
Drive back into the DL-11 and perform the first Switching operation.
Switching Between Productions
1- While the current production is playing, hold down both the UP and
DOWN Volume buttons until the GREEN LED starts to flash, then release.
(takes about 4 sec). The number of times that the GREEN LED flashes,
indicates how many productions are currently stored on the Flash Drive.
2- Press down the TEST button to verify if this is the desired promotion.
If not, simply repeat step one and two, until the desired promotion is
selected.
Notes:
1- If you release the buttons before the GREEN LED starts to Flash, it
simply RESETS the DL-11 with the current production.
2- The DL-11 accomplishes multi-messaging by renaming the files
stored on the Flash Drive. The selected production will have an "MP3"
extension, while a non-selected production will have an "MPP" file
extension.
•Using the Speaker
To test for proper operation, press and hold down the TEST button. You
will hear the audio that is being played. The speaker is connected directly to
the output, so if you hear audio through the speaker, it's coming out the
output. The speaker is for monitoring purposes ONLY and is not an
indication of audio quality.
•MP3 Audio Files
The DL-11 has no record capabilities at all. You must create new audio
programs on a computer, then convert them to an MP3 format before you
