AB-100 Digital
Audio
Repeater
Amp Ext. Inputs
Because it is completely solid state, a Digital Audio Repeater never re-
quires any maintenance. A sound which is recorded on a Digital Audio
Repeater will sound just as good twenty or thirty years from now.
Each AB-100, AB-Clock, AB-50 or DR-50 is a complete Digital Audio
Repeater. Their features include:
¥ Each card is a single complete audio playback system (except for
power amplification and speakers).
¥ Any sound that can be recorded can be digitized into a Digital
Audio Repeater. This includes any type of chimes, bells, voice an-
nouncements, music, alarms or sound effects.
¥ Message length is virtually unlimited on the AB-100 and AB-Clock.
Memory expansion cards can be added as needed. AB/DR-50s
each hold a single Eprom.
¥ Bandwidths of up to 15 KHz supported (35.1 KHz sample rate). This is
roughly equivalent to a new cassette audio tape. Each card will also
reproduce at 10, 7.5, 5, 4, 3, and 2 KHz bandwidths as well.
¥ Dynamic range of up to 72 dB, again roughly equivalent to a new
cassette audio tape.
¥ Up to 255 different messages can be stored on each repeater. On
an AB-100, any of these can instantly be accessed through the RS-
485 serial port or switch inputs. This lets you easily build interactive
audio systems by just adding the buttons to select different spiels! Up
to 99
1 of these can instantly be accessed by the AB-Clock through
the switch inputs. Multiple spiels can be accessed sequentially in the
AB/DR-50s.
¥ An AB-100 or AB-Clock can actually stop using any memory at all if
an instant of silence occurs.
¥ Two opto-isolated switch inputs, as well as a parallel auxiliary port
and RS-485 serial port on each card (AB-100 & AB-Clock only).
¥ OP-100 optoisolator available for auxiliary port. 1/4 J6 input is com-
patible with all our animation systems (AB-100 & AB-Clock only).
¥ Operating hours for the AB-Clock can be set for 24 hours a day or
specific times for each day of the week.
¥ The AB-Clock is factory laser trimmed to within +/- 10 PPM. A lithium
battery provides protection against power failures.
¥ Clock can be programmed for daily, weekly, monthly or annual ad-
justments to correct for slow or fast timekeeping.
¥ All AB-100 & AB-Clock configuration is done through the serial port
with easy to use menus. Configuration is stored in nonvolatile
EEprom memory. AB/DR-50s are configured using dipswitches.
¥ One optically isolated status output for remote ÔrunningÕ indicators
(AB-100 & AB-Clock only).

1 Although the AB-Clock can hold up to 255 different spiels, the software in the AB-Clock
limits your access to the first 97 messages from the two start inputs, push button on the
front, or keyboard. The real time clock can trigger any of the first 98 spiels for the
chimes and tolling of the hours. It can select and play any of the first 31 spiels from the
special show tables. Only the optional 1/4 J-6 input can access all 255 messages.
