:
Each AB/DR-3000 has eight optically isolated inputs along with one manual start button on its front
panel. The manual start button is generally used for maintenance and testing purposes. The eight opti-
cally isolated inputs are Ôswitch closure inputsÕ normally used to trigger the AB/DR-3000.
The eight optically isolated inputs are arranged in the same 1/4 J6 standard pinout used in all of
Gilderfluke & CompanyÕs Animation Control Systems. The AB/DR-3000 checks both the rising (switch clo-
sure) and falling (switch opening) edges of each input. This allows you to configure a AB/DR-3000 to do
one action on one edge of a switch opening or closing, and then take a different action on the oppo-
site edge. An example of this feature would be if you told the AB/DR-3000 to start looping on finding a
closure on one of the inputs, and then stop when the same input is opened again. The manual start but-
ton and 1/4 J6 inputs can be configured to tell the AB/DR-3000 to do any of the following things:
1) MUTE AUDIO: This sets the left, right or both channels immediately to their minimum output
level.
2) HALF MUTE AUDIO: This sets the left, right or both channels immediately to the half muted level
you have selected.
3) UN-MUTE AUDIO: This sets the left, right or both channels immediately to the normal output
levels you have selected.
4) FADE IN: This ramps the left, right or both channels to the normal level you have selected. The
length of the fade ins can be selected from .1 to 9.9 seconds.
5) FADE OUT: This ramps the left, right or both channels to the muted level. The length of the
fade outs can be selected from .1 to 9.9 seconds.
6) STOP REPEATER IMMEDIATELY: This immediately stops the left, right or both channels.
7) STOP REPEATER AT END OF CURRENT SPIEL: This stops the left, right or both channels at the end
of the current iteration of a loop.
8) START TRACK: This immediately starts the left, right or both channels. If no request for a specific
spiel has been received, then whatever spiel is next in line will be played.
Modifiers which can be used with the START TRACK command are:
a) LOOPING: When used with a START TRACK or START GROUP command, the spiel will con-
tinue to repeat. It can be stopped by either a STOP IMMEDIATELY or STOP AT END com-
mand is received. If the delay has been set on the repeaterÕs main menu, then this time
will be inserted between each iteration of the loop. The range of delay is from .1 to
999.9 seconds. This can be set independently for the left and right outputs if you are
using the repeater with mono spiels.
b) DELAYED START: When this modifier is set it will tell the repeater to wait for the amount of
time specified on the main menu before it actually starts playing. The range of delay is
from .1 to 999.9 seconds, and can be set independently for the left and right outputs if
you are using the repeater with mono spiels.
c) START GROUP: When the Group Start modifier is set, the Start command works just like
normal, except that it is relayed down the Digital Audio Bus. Any card that is assigned to
the requested group will be started within 44,100 of a second of all the others. This is
how perfect sync is achieved in bin loop applications. Delayed Start and Looping modi-
fiers can be used normally. All of the repeaters that are assigned to the same Group will
follow whatever this repeater is told to do.
9) REQUEST A SPECIFIC SPIEL: Any one bit can be used to select a specific spiel, or a group of
bits can be used to make up a binary address. The latter can be used to select a number of
different spiels using only a few inputs. The same bit(s) that are used to request a spiel can also
be used to perform any of the above input commands at the same time as the request is
made. This means that a separate command is not needed to start the repeater after a re-
quest is made. The request alone can also start the requested spiel playing.
There are several options that you can select for early start commands. These are start commands
that come while the AB/DR-3000 is still playing the last spiel. You can tell the AB/DR-3000 to:
