TOA SPECIALTY ELECTRONICS
SPOT ANNOUNCING MACHINE
AM-821
DESCRIPTION
The TOA Model AM-821 is a fully automatic spot
announcing machine for initiating recorded messages at
specific time intervals or on command during background/
foreground music play. Instant live announcements may
also be made. The biggest advantage of the AM-821 is that
it accepts any standard audio cassette tape, for recording
and playback of messages, however long. Unrecorded
sections needed for automatic playback can easily be
taped. The built-in AGC aids provides constant output
levels, for user-made message tapes. Unneeded
message(s) from #1 to #9 may be skipped. Time intervals
may be set by the built-in timer or by an external one. The
microphone serves for recording and paging. The AGC
keeps the paging level constant. An input is provided for
background music. Announcements have priority over
music. Optional mounting kits allow mounting in a standard
EIA 19" rack. An RM-820 optional remote microphone can
be used either for recording messages for playback on the
AM-821, or for direct live announcements.
