Primacoustic CrashGuard Drum Microphone Shield IsoTools
The Primacoustic CrashGuard is a unique sound-shielding device that isolates the drum microphone to attenuate the sound of cymbals during the recording process. This has the net effect of reducing interference between the two sources thus enabling greater control over the sound of the drum.
Compact and light weight, the CrashGuard is designed to fit most popular drum microphones and mounts directly on the boom stand using the microphone's clip to hold it in place. The high impact ABS construction is tough enough to withstand the hit of a drum stick by even the most aggressive drummer.
To ensure the microphone performance is maintained, the under-belly is fully coated on the inside with high density open-cell foam to absorb internal reflections and reduce phase cancellation. Plus the innovative design features an extended cable cutout that allows the microphone to be articulated for precise placement, further optimizing the performance.
Once in place, the Primeacoustic CrashGuard surrounds the microphone with a sonic barrier. By reducing the spill from the cymbals, more of the drum can be captured. This enables the engineer to add EQ to the drum such as increasing high end for more attack without accentuating the sound of the cymbal. On close proximity sources such as the high-hat and snare, the engineer enjoys greater balance over each sound.
The CrashGuard by Primeacoustic is an easy to use instrument shield designed to control the spill of cymbals entering the drum for greater control during the recording process.
- Reduces sound of cymbals from spilling into drum mics
- Light weight design fits most popular microphones
- Allows drum mic to be articulated for precise aiming
- Improves isolation for added control over each drum
Percussion instruments cut through the din on stage and bleed into other percussion mics. Crashguard allows greater seperation between mics.
CrashGuard attenuates the sound from the crash and ride cymbals reducing bleed on the floor tom mics.
When used for snare drum the CrashGuard attenuates sound from the high-hat allowing for better isolation and EQ for the snare mic.

Cymbals and high frequency splash
When the hi-hat is played, the high frequency sound from the cymbals will travel outward in a straight line in all directions. You can be certain that some of it will end up right at the nearby snare drum mic. By shielding the snare mic with the CrashGuard, the direct sound from the hi-hat is attenuated. It is important to note that high frequencies easily bounce off of hard surfaces. This can include drum shells, other cymbals and even the drum skin.
Even with the CrashGuard in place, some of the cymbal sound will find its way into the drum mic. The CrashGuard is merely reducing the level to give the engineer more control. This is particularly important when trying to add some attack to a drum. This is normally done using an EQ by adding high frequencies. If the cymbals are left unchecked to spill into the drum mic, their high frequency content will also be accented.
The shield and internal acoustic absorption
The CrashGuard is made from ABS plastic. ABS is a fabulous material… it is rugged yet springy. This means that when you hit it with a drum stick, it will not break. You can find photos of extreme measures where engineers have taped forks and other shields over microphones in effort to protect them from overly aggressive drummers. The CrashGuard offers a good measure of protection and is also heavy enough to actually attenuate some of the high frequency sound. You will also notice that the CrashGuard incorporates angles on both sides. This helps reflect energy away from the microphone inside. In fact, this is exactly the same approach used to build the Stealth bombers: the angular shape of a Stealth bomber is designed to reflect energy away so that it makes it difficult for Radars to pinpoint their location.
Who would have thought that such as simple device would actually such in-depth science behind the design… When it really comes down to it, the most important issue here is performance. And the CrashGuard does exactly what it is supposed to do.
The CrashGuard is a drum microphone shield designed to isolate the drum microphone to reduce it from picking up the spill from nearby cymbals. This allows the engineer to increase the attack of the drum by adding high frequencies without the cymbals becoming overly present.

How To Use The CrashGuard
The CrashGuard is extremely simple to use. It is designed to fit any standard boom arm or gooseneck. Begin my taking the mic clip off your mic stand boom arm. Make sure you leave the knurled washer on that usually comes with most booms. The CrashGuard comes equipped with a spare in case you do not have one.
Push the CrashGuard onto the mic stand boom arm. Then, take the mic clip and screw it onto the boom to hold the CrashGuard in place. Do not over tighten. Rotate the CrashGuard so that the microphone clip is pointing in the right direction and then slide the mic into the clip. You can now connect the mic by passing it through the rear access port. Snug tight the mic clip and boom so that everything is secure and you are set to go.
The CrashGuard is designed to fit most microphones and since most microphone clips allow the mic to be adjusted forward and backward plus be articulated up and down, you will find positioning the mic easy.
Keep in mind that for the most part, the CrashGuard will be used with a cardioid microphone. The cardioid pattern is created by mixing the sound coming in the front of the mic with the sound going in the rear, behind the capsule. Since the rear sound hits the diaphragm on the back side, it is out of phase and therefore causes cancellation. Try to leave some space between the mic head (capsule) and the inside top of the CrashGuard. This will reduce any effect the shell may have on the polar pattern.
