The Utah-400
If your UT-400/64 was ordered with internal SC-400 control cards and no other UT-400 frames
were ordered with your system, both MX-Bus ports should contain terminators. If your system
has internal SC-400 cards and there are multiple UT-400 frames, use the following illustration
as a cabling guide.
FIGURE 2-6.
Basic UT-400/64 cabling
Each 400/64 frame contains two looping reference BNCs. The signal type to be applied to the
input is different for audio and video frames.
Audio frames -- with or without internal SC-400 control cards -- require an AES-3 reference
signal for synchronous operation. This signal can be a standard AES-3 source that is timed
with the rest of the sources.
Video frames with internal control cards require analog NTSC, PAL, or Tri-level black burst
signals. This signal must be terminated in 75 Ohms, and is used as the vertical interval
switching reference for the SC-400. Video frames containing no internal SC-400 cards require
no connection to these BNCs.
