CHAPTER 1 Introduction and Specification Introduction The IFB System is a one-way IFB (Interruptible Feedback)1 communications system (a program interrupt system) created especially to meet the critical requirements of the television broadcast industry, as well as other live or recorded media applications. The system is composed of User Stations, Central Electronics and Control Panels. A modular approach assures the optimum configuration for each installation.
Central Electronics – Model 4010 The Central Electronics unit contains all the necessary control functions and electronics to provide the active link between the Control Station and the User Station. It accepts three (3) program inputs, four (4) microphone inputs and with keying signal inputs from up to four (4) Control Stations.
Splitter Assembly – Models 4022 and 4025A The splitter assemblies connect the control stations with the central electronics via 25-pair cable with micro-ribbon connectors. The Model 4022 features a single male connector paralleling two (2) female connectors to connect two (2) controls/stations to the central electronics. The Model 4025A features a single male connector with four (4) female connectors for use with up to four (4) control stations.

CHAPTER 2 Installation Standard Installation The Central Electronics, Model 4010, is a rack mounted unit. The rear of the Model 4010 must be supported with the brackets provided. Installation dimensions and outline drawings for all components of the Series 4000 IFB System are located in the Service Manual. The Central Electronics, Model 4010, provides a rear panel terminal strip for connection to the Model 4020 User Stations.
The Stage Announce output is balanced and provides an average signal level of about -5dBu. See Figure 6. The program inputs accept balanced lines with a signal level of +4 to +8dBu. See Figure 6. Connection To Existing Microphones, TW Type User Stations and Other Sources Any series 4000 Control Station can be connected to existing microphones (Figure 7 and Figure 8) and TW type user stations. A series 4000 Control Station can use the microphone in an existing TW type user station.
Expanding the Control Stations All Function The IFB ALL button on the Control Station causes all of the IFB buttons to be activated. The SA button is not activated. To make the SA work with the IFB ALL button, add the following diodes. Model Diode(s) 4001(M) D25 4002(M) D56, D61 4003(M) D100, D105, D110 Mono IFB When the switches inside the 4010 Central Electronics are switched to the right, both left and right channels at the user station will receive the interrupted program feed. See Figure 16.
FIGURE 2. A Typical Configuration The system may be expanded for up to 12 User Stations, three (3) Central Electronics, three (3) Splitter Assemblies, and four (4) Control Stations. FIGURE 3.

CHAPTER 3 Operation 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.
Control Station Operation, Models 4001, 4001M, 4002, 4002M, 4003, 4003M To use a Control Station, do the following: > Press the button or buttons of the channel(s) you wish to interrupt and speak into the microphone. User Station Operation, Model 4020 To use the model 4020 user station, do the following: 1. Connect the User Station to the Central Electronics via the 3-pin XLR-3 connector on the rear of the User Station. Polarity and correct connections are important for proper operation. 2.
Operating Distances With a telco pair, maximum operating distance averages 800 meters (1/2 mile). Doubling up the conductors in a telephone quad extends the operating range to 1600 meters (1 mile). Utilizing an extra power supply and transformers, the range can be extended to 8 kilometers (5 miles) on telco dry pair. See Figure 17. FIGURE 17.
