4 Line Telephone Digital
Announcement System

Introduction
Thank you for purchasing the Skutch
DL-4 four line Announcement System.
This unit was designed for heavy duty
applications, such as movie theaters,
that requires a pre-recorded
announcement to be played to a high
volume of incoming callers. Each caller
always hears the announcement from the
beginning, no matter how many lines are currently in use.
The DL-4 is a totally digital system. This means that there are no moving parts during
the play back process which makes this unit much more reliable then tape based systems.
Best of all the audio quality will not degrade with usage or time. The DL-4 stores the
audio data on a user replaceable manufacture specific SD memory card. Each SD card
can only hold one pre-recorded announcement. This card can easily be replaced or
swapped with another by the end user. This gives the end user the ability to have many
different pre-recorded announcements available to switch out at any time. This is an
awesome feature. The DL-4 can use SD cards from 128MB to 2GB in size. Not all SD
Cards are compatible with the DL-4. You should only use one of the recommended
brands as stated in the SD Card section of this manual.
A 2GB SD card, the maximum size that can be used, will record annoucements up to
17 Hours, 28.5 minutes in length.
The DL-4 uses a standard WAV file format that is compatible with Windows based
computers. This makes it possible for the end user to produce and/or store audio files
directly on their computer. The DL-4 uses a sampling rate of 16K per second, at 16 bits,
uncompressed, Mono. This provides an audio quality twice as good as most
telecommunication devices which only use a sampling rate of 8K per second.
The DL-4 is easy to use and is the perfect choice for high volume, announcement only
applications.
