Skutch Electronics DL-11 V1.02 - Manual

• Introduction
Thank you for purchasing the DL-11 Digital MP3 Repeater. This unit is
an easy to use, reliable audio source, for all Promotion-On-Hold applications.
The DL-11 will automatically play, any one or more, MP3 audio file(s) that
are stored on the standard USB Flash Drive. Once the last MP3 file has
finished playing, the DL-11 will immediately repeat the play sequence, over
and over again. 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. Once it is plugged in, it automatically starts playing. The unit has
an audio power amplifier with about 200mW of power so it can handle a
wide range of audio inputs, from key systems to pre-amp inputs. The DL-11
has a "button" controlled, adjustable volume control. The preset volume is
maintained even through power outrages. Please note that audio is taken
from the LEFT channel on stereo MP3 files. The DL-11 also comes with an
internal TEST speaker so that you can always test to see if your DL-11 is
playing properly.
• Max Length of Audio
The DL-11 can store up to one hour of audio on the supplied USB Flash
Drive. Stereo MP3 files use about 1MB of storage for each minute of audio.
With the DL-11 audio storage time is never a problem. To increase your
audio storage time, you simply buy a new larger inexpensive USB Flash
Drive. They are widely available, even at Wal-Mart. The following shows
the approximate play times with the different sizes of USB Flash Drives:
Drive Size Play Time
32MB 30 Minutes
64MB 1 Hour ***** (Supplied with DL-11)
128MB 2.13 Hours
256MB 4.26 Hours
512MB 8.52 Hours
1 GB 17 Hours
Based on an MP3 file at 44,100 Hertz Sample rate, at 128KBPS.
Works with both USB1.1 and USB2.0 Flash Drives
• Updating Audio Programs
There are two different ways which can be used to update the audio
program on your DL-11. The easiest method is to use the "Promotion-On-
Hold Update" software that is available at no charge on our web site. In this
case when your DEALER emails you a new audio program, a screen will
automatically pop up on your computer and instruct you to insert the USB
Flash Drive from the DL-11 into your computer. The software automatically
deletes your old program and will copy the new program on to the Flash
Drive. When finished, in approximately 6 seconds, it will prompt you to
remove the USB Flash drive and will instruct you to insert it back into your
DL-11. It's that simple! You don't have to know anything about computers.
You don't even have to check your emails! This software ONLY runs on
Windows based computer systems (XP/Vista/NT).
The second method is to manually delete the old file(s) and copy the
new MP3 file(s) on to the USB Flash Drive at your computer. This is for the
more experienced computer people. In this case, to prevent damage to the
USB Flash Drive REMEMBER that you MUST click on the "GREEN
ARROW" Safe To Remove Hardware ICON on the bottom right corner of
your TASK BAR on your Desktop, BEFORE removing the USB Flash Drive
from the USB Port. Sorry…This is a Windows thing! . This is not required
on the DL-11 AUTO LOAD software because our software is SMART! It
automatically does this for you!
• To Remove USB Flash Drive (DL-11)
Press both the UP and DOWN Volume buttons, at the same time, for
one second, then release. You can now safely remove the USB Flash Drive.
Pressing the buttons stops the DL-11 from playing. If you fail to remove the
Flash Drive within 3 minutes, after stopping it, the DL-11 will automatically
start to play again.
• To Insert USB Flash Drive (DL-11)
Simply insert the USB Flash Drive into the USB Port and the DL-11
will start playing within 10 seconds. If you did not remove the Flash Drive
correctly, you might have to remove the USB Flash Drive for 2 seconds, then
re-insert it again to start it. As long as you remove it properly, it will always
start the first time when you re-insert it!
