How To Use The VoxGuard

The VoxGuard is a simple device designed to control the ambiance around a microphone. When recording voice over tracks in the studio, it is often preferred that the tracks be completely void of any room ambiance or noise. This allows the engineer to add in digital reverb, echo to suit the mix. The VoxGuard is supplied with hardware adapters and an extension bar to accommodate many types and sizes of microphones.

The large curved baffle creates an acoustic boundary around the microphone that reduces room reflections from entering the mic. The high-density absorbing layer on the inside neutralizes reflections within the baffle. Slots cut through the ABS plastic shell eliminate resonance and open up the sound without sacrificing the isolation. The combination allows your mic to capture more of the direct sound and less room reflections.

Unlike other mic guards that employ heavy and cumbersome steel parts, the VoxGuard is lightweight and extremely easy to use. Its high-impact ABS outer shell fits snugly on a mic stand and secured using the microphone's clip, a shockmount or the included threaded stand adapter. The lightweight VoxGuard is easy to set in place without the usual fear of the stand falling over and damaging your microphone.

Setup directly on stand
The usual setup is to place the VoxGuard onto a mic stand using the threaded hold-down ring that is supplied to secure the VoxGuard in place. The microphone clip is then attached onto the protruding threaded stud. The lightweight baffle allows for very stable mounting on tripod mic stands and booms.

 

Setup with extension bar
Alternatively, the included extension bar may be employed to allow for more flexible mic placement. The extension bar slips over the mic stand and both it and the VoxGuard baffle are secured with a hold-down ring. The threaded adapter slips through the extension bar and mates with the mic clip or shockmount.

 

Pencil condensers and hand held mics
For added flexibility, the VoxGuard has been designed with a cable access slot to allow front address condenser and hand-held microphones to be used. Begin by attaching the mic clip to the knurled threaded attachment. Then, bring the microphone cable through the access port and connect to the microphone. The access port has been designed in such a way that the microphone can still be articulated so that it can move up or down to suit. That makes setting up the VoxGuard much more efficient.

 

Application 1 – Recording Vocals In The Control Room

The most common application for the VoxGuard is using it to control the spill and reverberant field in a recording studio. Simply mount the microphone in the VoxGuard and you are set to go. For greater acoustic control, having the artist’s back to a treated wall surface can further reduce the ambient field. Often, artists find that singing in the control room to be uncomfortable. The VoxGuard provides an instant vanity screen that can calm the artist and improve the performance.

Application 2 – Isolating An Acoustic Guitar Instrument Microphone

When recording several instruments at the same time, spill between them can pose problems. The VoxGuard’s innovative design allows hand-held or instrument microphones to be used while providing an excellent means of attenuating other instruments from spilling into the mic. Simply mount the VoxGuard onto the microphone stand and the mic onto the VoxGuard… point and record! With VoxGuard you hear more of what you want and less of what you do not!

Application 3 – Recording A Podcast In The Field

With today’s world of instant messaging, fast paced news and field reporting, setting up a remote broadcast or recording arrangement in less than ideal environments has become common place. The VoxGuard opens the door to improved audio by eliminating powerful first order reflections while attenuating outside noise. This makes it ideal for quick table-top setups, hotel lobby interviews and on-site dialog replacement. Simply mount on a mic stand to create a boundary around the microphone.
