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.
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.
The PJP-MC24 can further enhance the effectiveness of the PJP-100H/PJP-50R.
Open simultaneous connections with up to 24 locations
"Convener" function for summoning conferences from a Web browser
Manage extensions and usage status with SIP server functions
The PJP-50R/PJP-100H can be used as extensions under IP-PBX by linking with a SIP
server (NEC's UNIVERGE SV7000 SIP telephony server).
* The PJP-50R/PJP-100H are UNIVERGE certified products.
* Please inquire about SIP-linking with an IP-PBX other than the NEC SV7000.
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.
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.
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.
This program enables entry of various settings from a Web browser, including communication settings for connection with SIP servers and audio mode settings.
