Blackmagic Fiber CCU


Interface The DB-25 intercom and tally connector lets you connect to third party intercom and tally systems. A pin out diagram is provided below if you need to build a custom cable. Once you have wired up to the pins for engineering, production, tally or program audio input, you will need to set the menu accordingly on your Blackmagic Studio Fiber Converter.

This is a standard 4-wire (analog audio) interface. If connecting to a Encore/2-wire system, you will need an adapter.

For connection to a 4-wire interface, you will want to use pins 1-5 for the Engineering connection.
