CHAPTER 1 Description and Specifications Description The IFB-828 interfaces up to eight (8) RTS System’s Model IFB-325, 4020, or 4030 IFB Belt Packs to any RTS Digital Matrix Intercom System, and it provides power to belt packs. The IFB-828 may also be used as a simple program interface to feed two (2) separate program sources to each of eight (8) 4020 or 4030 belt packs (16 program sources to eight (8) belt packs total).

Description and Specifications Specifications Dimensions 19” wide x 1.75” high x 7.5” deep (483mm x 44.
CHAPTER 2 Installation Installation in an RTS Digital Matrix IFB-828 Location The XLR connector output from the IFB-828 provides unbalanced audio and DC operating power to IFB belt packs. Therefore, very long cable runs (over several hundred feet) from the IFB-828 to the belt packs may result in diminished performance due to DC resistance in the cabling and noise induced by surrounding equipment.
Installation • 10. Connect the appropriate 3-pin XLR output connector of the IFB-828 to the LINE (or LINES) connector of the IFB belt pack. Typical cable wiring is shown in Figure 2. NOTE: In the factory default configuration, the IFB-325 belt packs receive IFB audio on pin 3 of its XLR connector. In this configuration, the belt pack’s internal shorting plug J3 is set to pins 2 and 3 shorted. This is NOT the correct configuration for use with the IFB-828.
Installation FIGURE 2. IFB Belt Pack Interconnect Cable Wiring Diagram Using the IFB-828 as a Simple Program Interface with 4020 and 4030 Belt Packs Use Table 1 on page 6 and the cable wiring sources to each IFB-828 channel. In this application, each direct program input at the IFB-828 feeds to the NON-INTERRUPT channel of the belt pack, and the level is adjusted by the NON-INTERRUPT control on the belt pack; each IFB input feeds to the INTERRUPT channel and is adjusted by the INTERRUPT control.
