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).

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. Select a location for the
IFB-828 that is as close as possible to the belt packs or use appropriate precautions (shielded cable, heavier gauge stranded
wire, routing away from unsaddled equipment, etc.)
NOTE:
For broadcast applications, you typically locate the IFB-828 in the audio booth near the talent location, and no
special precautions are required.
To install an IFB-828 in an RTS Digital Matrix, do the following:
1.
2.
Mount the IFB-828 in an equipment rack or bay. It should be positioned near eye height when sitting or standing to
permit adjustment of the IFB program levels and to check the power indicator lights. There are no special ventilation
requirements.
Set the voltage selector switch on the back panel:
•
•
Select 110 for 110/120V, 50/60Hz operation
Select 220 for 220/240V, 50/60Hz operation
3.
Connect a 25-pair telco cable to J9 on the back of the IFB-828. Run this cable back to the audio distribution point for
the intercom system (punch blocks, etc.).
4.
Setup IFBs at the digital matrix intercom system using the intercom system configuration software.
5.
In AZedit, select the IFB icon on the AZedit toolbar.
6.
Double-click an IFB resource.
The Edit IFB window appears.
7.
Configure the IFB ports, as needed.
8.
Once you have configured the required IFBs, assign the IFBs to keypanel keys.
NOTE: For keypanel setup information, see the AZedit User Manual (p/n 93507769000).
9.
For each IFB that you setup, do the following:
•
Connect the output port from the matrix (that you defined in step 4) to an available IFB input of the IFB-828.
Make the connections at the audio distribution point where you have connected the cable from J9 of the IFB-828.
See Table 1 on page 6 for pin numbers.
5
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. 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 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.
Connect an earset to the IFB belt pack.
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.

Description
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:
•
6
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.

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