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.Mount the IFB-828in 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.
2.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.
