Installation
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. The
control on the IFB-828 front panel can be used to mix the NON-INTERRUPT audio into the INTERRUPT audio.
