You can easily store and maintain the VPM220W without disconnecting cables. Incorrect
cable disconnection may lead to microphone unavailability.
High-Quality Audio
The VPM220W supports 360-degree audio pickup at a radius of up to 6 meters.
The VPM220W delivers high-quality audio using frequency compensation technologies.
The VPM220W supports both mono and stereo applications.
Low Power Consumption
The VPM220W utilizes an energy-efficiency design. It consumes less than 2 W of power
in active mode and less than 0.7 W in standby mode.

which reduces the VPM220W's power consumption.
