Figure 1-2: MA-704 and AX-704 Units
A PIC-4704 unit is required for every four talent positions, or fraction thereof.
For example, a system with five to eight talent positions will require two
PIC-4704s. The same IFB system with three access locations will require three
MA-704s and three AX-704s, but will still need only two PIC-4704s. The
PIC-4704 performs the program feed and interrupt functions for each talent
position, and also terminates the IFB lines.
Figure 1-3: PIC-4704 Controls and Connectors
The PIC-4704 controls and connectors shown in Figure 1-3 are:
1. Program input level adjustment
2. Selector for non-interruptible program feed
3. Selector for interruptible program feed
4. Audio dip adjustment control
5. IFB inputs
6. Connectors to power supply (station or power supply)
7. Outputs to talent receivers
8. Program 1 loop through
9. Program 2 loop through
