About the Product
INTRODUCTION
The PJP-EC200 is a high-performance echo canceller box that enables smooth simultaneous talk during a
videoconference or a webconference.

■Echo canceller
Echo is a phenomenon that occurs when microphones pick up the audio reproduced from the speakers. The echo
canceller of this unit eliminates echo elements from sounds picked up by the microphones to enable smooth simultaneous
talk.
■Feedback suppressor
The feedback suppressor detects generation of acoustic feedback which occurs when a sound loop exists between speaker
output and microphone input and applies the notch filter to minimize the acoustic feedback.
■Auto analyzer
The auto analyzer optimizes this unit's audio settings to minimize the generation of echoes and acoustic feedback by
automatically analyzing the characteristics of a microphone and speakers connected to this unit and the acoustic
characteristics of your conference environment.
■Noise reduction
The noise reduction automatically detects ambient noises (generated by a fan or an air conditioner) and removes the
noises from sounds picked up by the microphones. By combining with the echo canceller, it effectively eliminates
unwanted noises from the pickup sounds and delivers clear sounds to the other end. The noise reduction of this unit also
works on the sounds from the other end.
■Auto gain controller
If you are using a boundary microphone, the volume level of sounds picked up by the microphone varies depending on
the distance between the talker and microphone. The auto gain controller automatically adjusts the pickup gain to
optimize the volume level of pickup sounds and minimize the volume differences caused by the distance to a talker.

Automatic Setup by Auto Analyzer
The auto analyzer function automatically sets the echo
canceller and feedback suppressor settings best suited for
your environment (types of microphone and speakers, size
of conference room, etc.).
Note
• During the measurement, the microphone picks up test tones
output from the speakers. To achieve the best results, keep the
room as quiet as possible during the measurement.
• Since this unit measures MIC/LINE INPUT IN 1 and IN2
individually, this unit proceeds in the next step if any of
measurements are successful. In case any measurement is
failed, this unit will notify you of the status of the channel after
the acoustic analysis.
If a measurement is failed
y
You can turn off the audio guidance which notifies you of
events during the auto analyzer process. For details, refer
to “Turning On/Off the Audio Guidance” (page 34).
■Before starting the auto analyzer
To achieve the best results, carry out the following
procedures before starting the auto analyzer.
• Install the microphone and speakers at places where
they will be located during a conference.
• Adjust the speaker volume to an appropriate level for a
conference.
• Adjust the input gain for MIC/LINE INPUT so that the
INPUT LEVEL LED does not turn on in red.
• Set whether audio input through MIC/LINE is output to
LINE OUT.
1 The auto analyzer starts.
By pressing AUTO ANALYZER, this unit outputs a
long beep to indicate the start of the auto analyzer
process and then plays back the audio guidance.

To quit the auto analyzer, press AUTO ANALYZE again.
2 Test tones are output.
This unit outputs test tones used for measuring your
acoustic environment. Since this unit measures MIC/
LINE INPUT IN 1 and IN2 individually, test tones
are output twice. The INPUT LEVEL LEDs on the
front panel blink during the measurement.
The auto analyzer quits. This unit outputs short beeps to
indicate an abnormal end and then plays back the audio
guidance which explains the cause of the error.
3 The acoustic analysis starts.
This unit analyzes your acoustic environment and
then optimizes the echo canceller and feedback
suppressor settings automatically. The INPUT
LEVEL LEDs on the front panel blink in a direction
from right to left during the analysis.
y
The analysis time varies depending on your environment
(types of microphone and speakers, size of conference
room, etc.).
4 The auto analyzer ends.
This unit outputs a short beep to indicate a normal
end or short beeps to indicate an abnormal end and
then plays back the audio guidance which explains
the result. Also, the front panel LEDs indicate the
result of the auto analyzer.
Note
If you move the microphone or speakers, the current settings
optimized by the auto analyzer may lose effectiveness or increase
the generation of echo or acoustic feedback. In this case, run the
auto analyzer again.
If you cannot feel the effectiveness
Run the auto analyzer again. If you are using this unit in
an environment where echo or acoustic feedback is rarely
generated, it may be difficult to feel the effectiveness. In
this case, you do not need to run the auto analyzer again
since your environment is already suited for a conference.
If the auto analyzer abnormally ends
Follow the audio guidance or check the status of the front
panel LEDs to change the installation location. For details
on LED statuses, refer to “List of Error Messages”
(page 55).

PREPARATION
The auto analyzer configures the settings based on the relative
position of a microphone and speakers. It is effective when a fixed
microphone such as a gooseneck microphone and a boundary
microphone is used.

Using the Web Menu
By using the web menu, you can configure this unit's settings in more detail. The web menu is accessible from the PC
connected to this unit. To configure this unit's settings from the web menu, set the DIP switch (DIP SW) to ETHER.
Notes
• If you set DIP SW to ETHER, the web menu settings are prioritized. The settings items you have configured using the DIP switch
should be reconfigured on the web menu. If you set the DIP switch to DIP SW after configuring the settings on the web menu, setting
items that are not available by the DIP switch are decided by the web menu settings.
• To access the web menu, Internet Explorer 6.0 (or later version) for Windows is required.
