Technical Features for Polycom SoundStation Premier
w/ Expansion Microphone

Item # 2200-01900-001 + 2200-02138-001
The Polycom SoundStation Premier EX w/ Extension Microphone (2200-01900-001 + 2200-02138-001) has 2 microphone ports for extra coverage. The Premier EX ensures the highest sound quality with 3 microphones and a digitally-tuned speaker for 360-degree coverage of an office or conference room. Polycom's Acoustic Clarity Technology uses digital signal processing with analog telephone lines to eliminate the clipping and fading that plague most speakerphones.

This technology improves speaker and microphone performance over the full bandwidth of the telephone line, 300 Hz to 3,500 Hz. Other features that boost system sound quality include dynamic telephone-line echo cancellation, dynamic room-echo cancellation, signal depression, microphone switching and digital filtering of voice signals. The Premier EX also features a separate echo canceller for each of its 3 console mics, optimized local speech quality and sub-band echo cancellation for incredible stability, even at maximum volume.

Key Term Definitions
Analog:
Analog is the original telephone technology, a system that converts air vibrations (like those created by the human voice) into similar electrical frequencies. Analog lines can support phones, fax machines, and modems and are typically found in homes or small office settings. Analog systems measure data in one continuous variable while digital breaks down and manipulates the data. One of the advantages of analog systems is that they dot not require a filter for band-limiting. Several SoundStation models operate on an analog system with features that are specifically designed for day to day communication.

Automatic Gain Control:
This adaptive technology is a standard feature in most electronic devices. Automatic Gain Control (AGC) takes the average output signal level and adjusts the gain to the appropriate level for input signal levels. For example, when a signal is too strong the AGC reduces its volume and when the signal is too weak the AGC increases the volume. In telephones the AGC is most commonly used when a conversation is recorded. The AGC will take the large signal from the local user and the small signal from the long distance user and produce a recording that is well balanced.

Cardioid Microphones:
All microphones have directional characteristics, which are determined by the way a microphone picks up sounds. Microphones can pick up signals from several directions or from one focused point. A cardioid microphone, the most popular of conferencing systems, picks up sound/signals primarily from the front of the microphone. When the pattern of cardioid sound pickup is graphed the shape resembles that of a heart, hence the name. These microphones focus on the sound in front of them and lessen ambient noise from the back or sides.

Dynamic Noise Reduction:
One of Polycom's signature features, Dynamic Noise Reduction (DNR) eliminates the unwanted background noise that plagues more traditional conferencing methods. This technology was first introduced in the 1980's and targeted noise reduction in long distance communications. DNR can cut down clatter by as much as 10 decibels and can be paired with similar systems. The Polycom systems that carry this feature provide the user with optimum microphone sensitivity while removing dynamic noise. DNR can really make a difference when conferencing with client's long distance, the level of professionalism will be much appreciated.

Echo Cancellation and Suppression:
With this technology you are able to enjoy echo free communication. With the cancellation and suppression processes, information is only sent across the line when someone is actually speaking. So when a person stops talking the signal is cut off, leaving no room for background noise to filter in and create an echo.

Full Duplex Operation:
The full duplex feature allows simultaneous flow of audio signals between your conferencing phone and that of the outside caller. Polycom systems carry a full duplex speakerphone, which can transmit and receive audio signals at the same time, in both directions.
