Monaural Earset Pin Out

Installation

•Connect the IFB program audio source to the intercom port that you defined as the program input port of the matrix (in step 4) and connect the IFB program audio source to the direct program input of the selected channel of the IFB-828.

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. To change the setting open the belt pack and reset the H3 shorting plug so that pins 4 and 5 are shorted. Refer to your IFB-325 manual for further information.

11.Connect an earset to the IFB belt pack.

NOTE: The Model IFB-325 accepts only monaural earsets. The Models 4020 and 4030 accept either monaural or stereo earsets. However, for the standard application of the IFB-828, only a monaural earset is required.

12.Set all belt pack volume controls and all level controls on the IFB-828 to minimum.

13.Plug in the IFB-828 power cord.

The main power LED on the front panel should light, and each channel LED lights indicating power is being supplied to the belt pack output on that channel. Verify the matrix is operational and that all program sources are operational.

14.During normal operation (no IFB interrupts activated), have each talent position adjust their belt pack volume control for a comfortable program listening level. (Use the INTERRUPT control on a model 4020 or 4030 belt pack.)

15.For each IFB:

•Activate the keypanel key assigned to the IFB. The program audio should be interrupted at the associated IFB belt pack, and the mic audio from the keypanel should become audible.

•While the IFB key is activated, adjust the appropriate level control on the front panel of the IFB-828 to mix the desired amount of direct program audio back into the keypanel’s mic audio signal.

When the IFB key is released, the mic audio should cut off, and the normal program audio should be restored.
