Stop and Listen Digital Message Recorder 'S': Operating Instructions

OVERVIEW
The DMR 'S' is a solid-state monaural audio recording and playback device that operates much
the same as a tape recorder. Because it is solid state there are no parts to wear out, ensuring
year after year of trouble free service, with no loss in fidelity.
The DMR 'S' is capable of recording and storing an audio track of up to 4 minutes total duration,
depending on how a series of internal dip switches has been set.
Audio is loaded into the DMR 'S' from an audio source with a line level or headphone output and
is then converted into a digital format and stored on state-of-the-art DRAM memory chips. On
playback audio is converted back into it's original (analog) form.
An internal memory backup battery maintains standby power to the memory, ensuring that
messages are safe even after a long power failure. An automatic float-charging system is built-in
to maintain the internal battery in peak condition.
The internal amplifier allows the DMR 'S' to be played back directly into an external speaker with
no need for additional equipment. A line level output is provided for applications where the audio
will be played back through other equipment.
Playback is initiated using a number of different methods, whether from the front control panel or
from a variety of external switches or triggering devices. The system can also play continuously
using a simple start jumper connected across the rear switch contacts.
At Stop and Listen we have gone to great lengths to ensure that your new DMR 'S' represents the
ultimate in durability and ease of use. As you become more familiar with the DMR 'S' you will find
that the on-board recording features can add a whole new dimension to your application. You will
soon be able to communicate much more effectively with your audience.
