This microphone system allows you to put up to 4 microphones around a room and control the level of each mic independently so that all subjects in the room can be heard easily and equally. The combined audio from each mic is fed into the USB sound adapter where you can add noise filtering and echo cancellation as needed. The audio is then sent into your recording software as usual.
This system includes the following gear:
Andrea USB-SA - USB sound adapter with active noise filters and echo cancellation
4 x MS-COURT-BOUNDARY - Ultra-high sensitivity Omnidirectional Boundary microphones
4 x Rode VXLR+ - microphone XLR adapter with power conversion
Rolls MX124 - 4 microphone mixer
SP-XLRF-MINI-2 - 24" cable to connect mixer output to USB sound adapter
