CHAPTER 1 Introduction and Specification Introduction The IFB System is a one-way IFB (Interruptible Feedback) 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.
Inside the Model 4010, a single large circuit board is used to mount all electronic components. A rear panel terminal strip provides connections for the program inputs, IFB outputs, SA output, and relay contacts. Connection between the Control Stations and the Central Electronics is made through a 50-pin micro-ribbon connector.
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.
Specifications Gain Model 4010 Central Electronics 54dB to 14dB Frequency Response Nominal Output Level 30Hz to 16kHz, +1,-2dB -10dBu, balanced, Z=300 Ohms Noise Size And Weight Interrupt Channel, <-75dBu 4001/4001M Non-Interrupt Channel, <-83dBu 1.72”H x 8.5”W x 3.4”D Total Harmonic Distortion 2.1lbs/2.7lbs...
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.
Control Station’s switchboard, the priority of that Control Station can be changed. See Figure 11 through Figure 13. If desired, the priority may be defeated by removing U6 and U16 in the Model 4010 Central Electronics. In this mode all Control Stations have equal priority.
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. Power Connection to Series 4000 Control Stations...

A Typical Configuration FIGURE 2. The system may be expanded for up to 12 User Stations, three (3) Central Electronics, three (3) Splitter Assemblies, and four (4) Control Stations. A Configuration– 2 System FIGURE 3.
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: Plug a stereo headset into the test jack on the front panel of the input 1.
Substituting TW Intercom Stations for IFB User Stations Any RTS TW intercom station may be substituted for a 4020 User Station. The BP-501 User Stations provide stereo IFB. Any other User Stations should have the channel-select a switch set to channel 1to receive the interrupted monaural audio. A TW User Station with the LP (Local Power) option can be used to operate on a dry pair IFB feed providing long distance operation up to 8 kilometers (5 miles) with stepup and stepdown transformers.
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.
