Specification Sheet
DESCRIPTIONS
The Phonum speakerphone is the ideal solution for
mobile conferences over the internet in the office or at
home. The primary operation is via Bluetooth® with a PC,
laptop or smartphone. In addition, Phonum has a USB
port as a secondary interface, so that the device can be
used even with poor radio communication.
Phonum allows small conferences, including video or
teleconferencing, with participants at remote locations.
In the office or conference room on site, the maximum
number of participants is 8 people.
Phonum is powered by a Li-Ion battery, which is charged
via the USB port. If necessary, the device can also be
operated via USB, the battery is then charged parallel to
the application.
Phonum is operated via capacitive touch sensors with
which the user accepts or ends calls, increases or
decreases the volume, selects the polar pattern and can
mute or activate the microphone.
Phonum has three microphone modes: omnidirectional,
cardiod and beamforming. When the microphone is
operating in the beamforming mode, the microphone
automatically adjusts to the direction of the person
speaking. The selected microphone mode is indicated by
line-shaped lights.
