Mount Primacoustic's VoxGuard VU on your mic stand and keep room reflections to a minimum. Sweetwater Sales Engineers know that unwanted reflections will ruin any recording in a hurry, causing phase cancellations which ultimately distort the tone you're trying to capture. The VoxGuard VU acts as an acoustic shield while the Plexiglass window lets you maintain a sight line between vocalist and engineer. It features a 15" x 18" curved absorption panel with pressure-release slots to eliminate resonance. An adjustable mic-clamp slider is also included. Perfect for any vocal recording session, the Primacoustic VoxGuard VU is a great solution for keeping the room sound out of your microphone.
