High-quality audio
The VPM220 supports a sampling rate of up to 48 kHz and a full frequency range. It is
able to sample sound at rates lower than 22 kHz, which means that it can completely
pick up any sound recognized by human ears. The VPM220 significantly reduces signal
loss caused by analog transmission cables, while offering a hi-fi stereo experience. These
capabilities are made possible through the integrated digital signal processing and
transmission technology and the Acoustic Echo Cancellation (AEC), Automatic Gain
Control (AGC), and Automatic Noise Suppression (ANS) functions.
Superior sound experience
Embedded with three heart-shaped microphones, a single VPM220 supports 360-degree
sound pickup with an optimal range of six meters. This allows participants at the local
site to hear every sound nuance coming from participants at the remote site.
Power saving
Highly energy-efficient, the VPM220 requires no more than 2.5 W of power when
running.
