PortaCom is a flexible, high performance wired intercom built smart and simple so it won't knock a hole in your budget. For the price of many single channel systems, PortaCom gives two channels, delivering powerful, low-noise, broadcast quality sound. The PortaCom system tailors to your needs as it is expandable to fit your situation. Two channels offers the advantage of extensive communication, so you won't get tangled in crosstalk. A director can cue cameras or talent on one channel ad a lighting or sound crew on the other channel. Coaches on offense can call plays at the same time their defensive coaches are reviewing strategy, while the head coach communicates back & forth with both of them.The main components include a power console, belt packs and headsets. Station-to-Station communication is made using standard microphone cable with 3-pin XLR connectors. The PC-100 power console has four outputs and can be expanded and configured in a variety of ways using the B3-100 branch boxes. Start with a basic two person system and expand step by step all the way up to a 20 person system - all running from a single AC power supply over standard mic cable. A typical 6-headset system is shown below.PC-100 Power ConsoleThe PC-100 has a power switch, an AC power input, and four 3-pin XLR output jacks.
