Operating Instructions
The Series 4000 IFB System is very easy to use. The discussion below covers initial setup as well as the actual operation of the
equipment. Field setup and connection of the Model 4020 User Station vary considerably depending on you needs and on the
physical configuration of the studio, truck, arena, theatre, golf course, etc. you have to equip. The basics for Model 4020 setup
are discussed throughout this chapter.
Setup and Operation of the Central Electronics, Model 4010
After you have made all connections, do the following:
1. Plug a stereo headset into the test jack on the front panel of the input 1.
2. Turn the monitor switch to PGM 1.
3. Verify program.
Then check programs 2 and 3.
CAUTION: The program level is louder than the mic monitor and the output monitor levels.
To set program level to the User Stations, do the following:
1. Turn the monitor selector switch to OUT 1.
2. Set program-select switches under OUTPUT 1 to the desired channels.
3. Set the program level to its midpoint.
4. Have someone depress an IFB 1 button on a Control Station and speak into the microphone.
5. Compare the interrupt level with the program level and adjust program levels as needed for a balance
between the program and interrupt audio.
6. Repeat this procedure for the remaining outputs.
When the monitor-select switch is in the SA position, the left headphone receives the SA program before it is
interrupted. The right headphone receives SA audio after the interrupt switch.
