By external activation
External equipment can be used to activate the EV-20A's
playback of a selected message by transmitting a pulse
exceeding 200ms. In this case the broadcast is one time
only and will not be repeated unless the contact is
maintained.
Digital high quality sound
Fully digital, the EV-20A maintains the same high level of
sound quality that is CD-level over time as there are no
moving components to wear out. The EV-20A's frequency
response is specifically tailored to enhance announcement
audio quality. Announcements can also be punctuated with
chimes. Being fully digital reduces mechanisms so the
EV-20A is totally reliable.
Useful software CD-ROM accessory
EV-20A software containing a variety of useful files
including a library of music files* is provided. System
requirements: PC running Windows 2000/XP.
