These extra microphones are for use on the Polycom SoundStation VTX 1000 conference system.
The pack consists of two microphones that plug directly into the VTX 1000 main unit. The microphones, when attached to the unit, increase the standard coverage.
The microphones, like the VTX 1000 sit on top of the meeting room table and stretch to the farthest end to pick up the voices of participants who may be outside of the standard 20 feet pick up range. This then makes the VTX 1000 when used in conjunction with the extra microphones suitable for larger meeting areas with more participants.
The microphones are styled to compliment the attractive VTX 1000 conference system.
