Option Card Slots
There are three slots for the optional audio Input/Output

The space for the SMPTE/V SYNC card is located directly
under the MASTER OUT XLR connectors. Audio option
cards are next to the power switch. The audio option cards
can be used in any of the audio slots, but for TANDEM
operation, the TANDEM card MUST be used in Slot 3.
Video Sync Input [V SYNC]
This is used to connect a vertical synchronizing signal from
a video device.
See Chapter 17, Options in the Users' Guide for more
