Production Intercom’s IP901 Connect features self-balancing DSP and intelligent echo cancellation, addressing issues associated with full duplex IP audio communications, such as echo, level balancing, and compression. The system’s “learning” DSP has been adapted from a design developed for the VOIP telephone industry, and a joint venture with Barix, an IP communications company, make this unit an advanced means of intercom-over-internet communications. Connections include 3-pin XLR and Cat5, and programming is similar to setting up a router. Balancing of audio and echo cancellation is preformed via the “learn” button on the front panel. In addition, the input and output levels may be adjusted independently using the recessed screws on the front panel. A built in VU meter assists in determining the level adjustments. The unit is compatible with internet-capable devices such as laptops, desktops, and PDAs. Two units may be used in a point-to-point configuration to give uninterrupted full duplex communication between two intercom systems virtually anywhere in the world.
