Do one of the following depending on your configuration:
• If your Mix Rack has a ribbon cable with
three connectors
(the Clock Source Jumper cable) connecting the ports la-
beled “Snake” on the first and second Mix Engine cards to
the port labelled “P1 Mix Engine” on the Hub 48 card (see
Figure 12), disconnect this cable from both Mix Engine
cards. Do
not disconnect this cable from the Hub 48 card.
– or –
• If your Mix Rack has a standard dual-connector ribbon ca-
ble connecting the port labeled “Snake” on the first (inner-
most) Mix Engine card to the port labeled “P1 Mix Engine”
on the Hub 48 card (see Figure 13), disconnect this cable
from the Mix Engine card. Do
not disconnect the cable
from the Hub 48 card.
7
Disconnect the ribbon cable from the port labeled “FOHA” on
the first (innermost) Mix Engine card. This cable connects the
main IO card to the first Mix Engine card.
8
If any ribbon cables are attached to the ports labelled
“FireWire” (located to the right of the “FOHA” ports) on ei-
ther or both Mix Engine cards, disconnect them, noting their
location. These cables are connected to any installed VENUE
record/playback option cards and/or the Ethernet Snake card.
In most cases there is only one cable present, and it is attached
to the first (innermost) Mix Engine card.
