IISX 4-Place Intercom Prefer to go portable? Put this in your flight bag. Our IIsx is a 2-place, voice activated mono intercom with modular design. Powerful. Functional. Expandable to 4-place. And it can run off your aircraft battery through the included cigarette lighter. It's an intercom you can carry anywhere into the wild blue yonder. Just plug it in and take off. Efficient, modular design with 2 to 4-place expansion capability. Includes voice activated circuitry, adjustable volume and squelch, auxiliary input and output jacks, pilot isolate and cigarette lighter adapter. Plus, it's lightweight and easy to carry. This versatile portable unit provides communication to go. The modular design offers expansion capability to the backseat if needed. And because the SR-4 expansion module has a 6-foot cable, passengers in back don't have to strain their headset cords to reach an intercom box located next to the pilot.
