Model 78
Central Controller Version 1
The
Model 78 Central Controller can be ordered from Studio Technologies to
perform an 8-channel make-before-break A-B input select function. This implementation is
identified as the Model 78 Special Version 1. With this version either
input A or input B can be selected to be routed to the output. A special
10mSec make-before-break switching sequence has been implemented. The
input-to-output gain is configured for unity, with a +4dBu nominal
operating level. The input trim potentiometers allow signals over a wide
nominal level to be adjusted to achieve a +4dBu nominal output level.
The
Model 78 Special Version 1 may be appropriate for use in post-production
audio, broadcast, and other specialized multi-channel applications.
