The ITC-100 is a half-duplex system, which means only one person can speak at a time, as audio is carried over a single wire both ways. It does not support full-duplex or party-line communication.
The ITC-100 only supports wired communication.
Max Cable Length
You can run 5-pin XLR cables between the base station and belt-pack up to 200 Meters.
Please see this support article for more information.
Number of Conductors in Cable
The ITC-100 intercom cable utilizes 5 conductors and a foil shield. Datavideo offers pre-made cables in a variety of lengths. CB-3 (20 Meters or 65ft), CB-4 (50 Meters or 164ft) and CB-76 (76 Meters or 250ft available only in the USA).
The 5-pin XLR cable conductors are 20 gauge wire.
How to Feed Program Audio
The ITC-100 does not feature an Aux input for your program audio, but one of our customer's designed a solution and detailed it in this video.
Audio Level of the 2-Wire Line: 0 dBm or -15 dBm?
Compatible 3rd Party Headsets
Many headsets will work with the ITC-100, but some professional sets have 4-pin XLR connectors. The Datavideo CB-8 adapter allows you to connect a 4-pin XLR headset to the ITC-100SL belt pack. The wiring schematic for the CB-8 is available in this support article.
The ITC-100 has a built-in noisegate. This reduces the background noise in a busy environment to be heard when speaking, by not allowing low volume sounds to come through. The side effect is that it will also do that when you are too far from the microphone. That can be heard as interrupted speech or even no audio at all. Best way is to speak closely to the microphone or to use a headset such as HP1 or HP2 and keep the microphone positioned closely to your mouth.
