Auralex Acoustics Microphone Isolation Shield w/ Hardware Mounting Kit - MudGuard V2 Convex technology redirects internal sound energy away from the microphone Solid shell reduces external noise while filtering unwanted overtones Minimizes excessive room ambiance and off-axis sound Uses Auralex Studiofoam for maximun absorption performance Mounts easily to most microphone stands If the mic capsule is positioned about <span class="a-text-bold">1/3 of the way into the device</span> (~5.5 inches from the rear) <span class="a-text-bold">a nice balance is achieved</span> betweenthe <span class="a-text-bold">reduction of room sound</span> and the <span class="a-text-bold">natural sound of the mic without phasing.</span> If the mic capsule is <span class="a-text-bold">positioned further into the MudGuard</span> (~3.5 inches from the rear), the absorptive effect of the Studiofoam liningwill be apparent as a <span class="a-text-bold">very dry and somewhat dark presentation</span> tothe vocals. This is due to a<span class="a-text-bold">reduction in the upper mids and higher frequencies</span> making the lower mids more apparent. If the mic capsule is positioned <span class="a-text-bold">toward the front</span> of the MudGuard <span class="a-text-bold">a more live sound is realized</span> as the micis exposed to a greater amount of room reflections,without the device adding its own colorations.
