The digital audio store unit uses MPEG-1 Audio Layer 3, more commonly
referred to as MP3, digital audio encoding/decoding format to store and play
audio information. It uses a USB memory stick as the physical storage media
and is non-volatile, which means it does not require any backup supply or
battery. This removable memory stick must be pre-loaded with MP3 files and
then plugged into the socket located on the circuit board. The unit comes
supplied with a memory stick containing sample messages, chimes, alarms
and background music.
These audio files are organised into four distinct groups; the first three can
each contain up to five files, but the fourth group (background music) has
no practical limit to the amount of files it can store. These groups have been given
descriptive names so as to help organise and ease access to the data. The files and
their groups have a hierarchical priority structure and an adjustable interval timer is
available on the second file in group 1.
The files in the first three groups are triggered by means of a simple contact closure
applied to the relevant screw terminals on the main circuit board. Files in the fourth
group are played in a random manner automatically when the background music
facility is activated.
The quality of the audio output is dependent on the bit rate of the audio files used; low
bit rates are suitable for speech, whereas higher bit rates are suitable for high quality
music (commercial CD quality).
Audio output is at line level either via stereo phono connectors or a balanced mono
signal by means of screw terminals. A stereo 3.5mm headphone jack socket is
provided to allow monitoring of the unit’s output.
The unit is housed in a durable metal case and is powered by a 12v DC ‘plug top’
power supply (supplied).
