2.1 Installation of Rear Connector Panels
Miranda Densité-series cards are each associated with a rear connector panel, which must be installed in the Densité
frame before the card can be inserted.
The AMX-3981 card is designed to fit into Miranda’s Densité-3 frame. Four different rear connector panels are
available:
• AMX-3981-75D-3SRP
Single-slot-width panel with 75
Ω audio
• AMX-3981-110-3SRP
Single-slot-width panel with 75
Ω audio
• AMX-3981-75-3DRP-F
Double-slot-width panel with 75
Ω audio and fiber I/O
• AMX-3981-110-3DRP-F
Double-slot-width panel with 110
Ω audio and fiber I/O
See section 2.4 for details of the signal connections available on each of these panel types.
All cards and rear panels can be installed with the frame power on. The card has connectors which plug into a mid-
frame mother board for distribution of power and for connection to the controller card, and a second connector which
plugs directly into the rear connector panel for input and output.
The rear connector panel must be installed with the card out of the frame.
• To remove an existing card from the slot, tilt up the swivel handle on the front of the card to lever the connectors
apart, then use the handle to pull the card straight out of the slot.
