PJP-50R

PJP-50R has three built-in terminals. The LAN port provides high sound quality conferencing between Projectphones. The LINE port (for analog phone lines) facilitates calls with land line phones, cell phones, and analog phone terminals. And to connect to a PC as a microphone speaker for Web conferencing or "soft phone" use, you can use the AUDIO (IN/OUT) port. PJP-50R offers a multiinterface voice conference system that can be used in various ways according to the application.

With its various connectors, PJP-50R can open calls with simultaneous IP, analog phone, and audio connections. Parties away from the office can join IP audio conferences from their cell phones, or join Web conferences from a telephone (voice only).
* Participant can talk with location A by cell phone through PJP-50R at location B

IP connections offer 7 kHz of voice bandwidth, or approximately twice that of analog phone lines (3.4 kHz). Because the PJP covers almost all frequencies of the human voice, it creates a realistic conferencing experience where you know who is talking simply by the sound of their voice.

The PJP-50R/PJP-100H supports audio conferences of up to 8 locations without an MCU (multi-point control unit). The PJP-50R/PJP-100H support an audio conference of up to 8 locations without an MCU. They are able to connect 4 locations with a mesh connection and 8 locations with a cascade connection.

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.

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.

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.

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.

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.

Microphone array's talker detection function and the speaker array's virtual sound source generation function combine to facilitate the "talker position reproduction mode", which modifies audio output according to the seating arrangement of the callers. Sound is output to different positions making it easy to distinguish between multiple voices (up to three talkers per location over a two-location IP conference).

Easily distinguishable voices without crossing, even during multipoint conferences The voices can be reproduced from different speakers according to the locations of the talkers. Outputs without crossing not only make voices easily audible, but also enable easy identification of the location of the current talker.
