The PJP is a conference microphone speaker with a built-in high performance echo canceller. When connected to a PC with a USB or audio cable, the PJP enhances your softphone* or Web conferencing system for multiperson response that is as smooth as video conferencing.

Smooth duplex performance
Echo can occur in an audio conference system when the microphones pick up the audio reproduced from the speakers. To counter this, the Projectphone incorporates a high-performance adaptive echo canceller that eliminates any of its own sounds that may be picked up. Combining this with a design that minimizes feedback of reproduced sound, it offers smooth full-duplex performance that is easy on both the talkers and listeners.
Adaptive echo canceller for use in any kind of room
The Projectphone's adaptive echo canceller "studies" the operating environment and automatically adjusts the echo-filter factor accordingly. And since it performs well in many different acoustic conditions, you can easily hold conferences in whatever room or space is available.
Even when next to a projector, noise reduction eliminates the sound of the fan
Built-in noise reduction eliminates noise even in rooms with constant sound such as from projectors and air conditioners . Noise is removed from the ambient sound picked up by the microphones. The listener hears only clear voices.
Zone mode ideal for quiet rooms
Zone mode is recommended for quiet rooms because of its wide audio pickup range. Thanks to the high audio pickup performance of the arrayed microphones, voices are picked up accurately even when distant from the microphones. Because the pickup range can be adjusted, you can ensure that even noises such as from air conditioners and projectors are not picked up.
Spot mode ideal for noisy environments
In this mode, the narrow directivity of the arrayed microphones allows you to pick up sound only from a specific direction. It is the optimal mode for conferences limited to one or two participants, or in noisy environments. Even in open spaces or when surrounded by noise, only the unadulterated voices of the talkers are heard by the other party.
Tracking mode automatically detects the talker
A microphone beam position detection function automatically tracks in the direction of the talker. Only the unadulterated voice of the talker is picked up. Also, by setting the PJP to pick up in a certain direction, you can ensure that it will not track noise sources such as projectors. Because pickup is directed toward the talker, this mode is useful for multiperson conferences where noise sources are present.
Design based on acoustic engineering
The PJP has been structurally designed based on acoustic engineering principles to achieve conferences that are easy on both listeners and talkers. The left-to-right microphone array is optimal for pick up and echo cancelling. The undermounted speakers are acoustically designed so that sound reflected off the tabletop reaches the ears.
Connecting to a video conference system
By connecting with audio cables, the PJP-100UH can be used as an echo canceller — equipped microphone speaker in a video conference system.
Switching the audio section creates a smoother conferencing experience for both listeners and talkers.
Supports daisy chaining for conferences of 10 or more persons
Whether you want to set up in a large conference room or join a multiperson conference, connecting PJP-100UH with an audio cable lets you expand the pick up range. You can even hold conferences with dozens of people, because up to four units can be daisy chained.
* Connecting extra units introduces additional noise and can lower the sound quality.
** PJP-100UH can also be connected to PJP-50R and PJP-100H.
