- AB-100 and AB-Clock Connections -
The connections to the AB-100 and AB-Clock are identical. See the sec-
tions of this manual that cover the AB-50 and DR-50 for their connections.

Line Level Output:
The output of the AB-100 and AB-Clock is a +10 dB balanced output.
The connection is through a 1/4Ó stereo phone plug. If this output is operat-
ed in single ended mode, the unused output MUST be grounded. If it is not,
then the output will be excessively noisy. As shown by the illustration on the
end of the case, using a mono 1/4Ó phone plug will automatically ground
this unused output in single ended applications. Use a 1/4Ó stereo phone
plug only in balanced applications.
Aux. Port & 1/4-J6 Input:
The AUX PORT is used to select a specific spiel on a single AB-100 or AB-
Clock. You will need to select the OP-100 AUX PORT OPTO-ISOLATOR option if
you want to use the Aux. port. The input to the Aux. Port is the same 1/4 J-6
connection used by all of our Animation Control Systems. If you are using a
source other than our Animation Control Systems, the connections are as
follows:

JP-11 is used to select whether the 1/4-J6 input is to be run from external
power or from the same power supply as the AB-100 or AB-Clock. With JP-11
in the Left position, the inputs use same power supply as the AB-100 or AB-
Clock. Any switch closure between the data bits and ground will trigger a
spiel. With JP-11 in the Right position, an external source of power is needed
by the 1/4-J6 input. This is the safer method of operating this port, since any
spikes on these input lines wonÕt be coupled into the AB-100/AB-Clock
through its power supply. The input to the 1/4 J-6 connection is simply eight
opto-isolators. Each input is equivalent to turning on a LED with a 4.7 Kohm
in series.
