The RD 2008 digital recorder can be used for recording and delivering announcements, alarm messages, advertising spots, etc. It offers two operating modes:
a) recording/playback of 4 messages of 30 seconds each
b) recording/playback of 2 messages of 60 seconds each.
As a source for recording messages, you can use the microphone on the front panel, an external dynamic microphone, or an external audio source (e.g. cassette player). At the moment of recording, you can decide whether to have the announcement preceded or followed by a warning signal (siren).
The RD 2008 is equipped with an input for an external musical source, which is normally played in the areas covered when there is no announcement playback in progress. When an announcement is being played, this source is automatically excluded.
TAPE IN input with adjustable sensitivity. MUSIC IN input. Input for external microphone, with adjustable sensitivity.
