The Main Camera is generally mounted on top of the primary display. The Main Camera is a high
quality color camera with a fast pan/tilt/zoom action. The Main Camera is controlled by the touch panel
control, or the system's infrared remote control. You can pre-store up to 40 camera positions using
Camera Presets.

Digital Natural Audio Module
The Digital Natural Audio Module (D-NAM) is designed to enhance audio quality during a
videoconference. The D-NAM provides natural sounding audio - as if the person, or another sound
source, in conference is present in the same room as you. The D-NAM is a frequency-compensated
sound system optimized for voice and other sounds that appears in modern videoconferencing. It is
designed and dedicated specifically for videoconferencing requirements. Use of the highest quality
speaker elements as well as proper amplifier- and software techniques minimizes signal distortion.
Monitor- or television speakers are disabled, and the sound is completely handled by the D-NAM.
D50326.05
TANDBERG's award-winning AudioScience microphone is a transparent, ceiling-mounted, wide-
coverage, boundary microphone, which can eliminate the need for table microphones. It is
designed to pick up the audio from all conference participants seated within in its pick-up area,
defined by hemisphere of approximately 14-foot (4.25m) radius extended in front of, and to the
sides of the microphone. Using the Automatic Gain Control (AGC) on the codec maintains the
audio signal level at a fixed value by attenuating strong signals and amplifying weak signals.
The optional high-quality table microphones are designed to lie on a table during a
videoconference. The ideal location for the microphone is on a flat surface at least 6.5 ft (2m)
from the front of the system. The microphone cable should always point towards the system.
The system will automatically equalize sound levels. Loud and soft voices are picked up and
transmitted to the far end at approximately the same level.
The optional TANDBERG Touch 'n' Talk microphones are high-quality, unidirectional table
microphones with camera tracking capabilities. The touch-sensitive on/off switch on the
microphones can be configured and utilized for the videoconference environment to call
attention to the person who is speaking at any given moment.
This option connects to line level input 4 on the TANDBERG codec and provides up to 10 Touch
'n' Talk microphones per unit. Up to four units may be daisy-chained.
