Echo is a phenomenon that often occurs when the microphones pick up the audio reproduced from the speakers in an audio conference system. The Projectphone incorporates a high-performance adaptive echo canceller and an ideal design to eliminate echoes and reproduce voices with higher clarify. In addition, the PJP-100H incorporates 3-channel adaptive echo canceller that enables you to remotely specify audio output from each speaker position (Divide mode).

Removes echo even in a room with high reverberation
The Projectphone's adaptive echo canceller automatically adjusts the echo-filter factor to the optimum setting for a given environment.
With the Projectphone, you can hold a meeting in any type of room or space.
