The unique Primacoustic CrashGuard isolates your drum microphone to attenuate the sound of cymbals while you re recording. The net effect: reduced interference between the 2 sound sources for greater control over the drum sound. Compact and lightweight Primacoustic CrashGuards fit most popular drum microphones. Just mount directly on your boom stand using the microphone s clip to hold the CrashGuard in place. The high impact ABS construction is tough enough to withstand drumstick hits by even the most aggressive drummer. To ensure the microphone performance is maintained the CrashGuard s under-belly is fully coated with high-density open-cell foam to absorb internal reflections and reduce phase cancellation. Part of the innovative CrashGuard is an extended cable cutout permitting precise microphone positioning further optimizing performance. Once in place the CrashGuard surrounds the microphone with a sonic barrier. By reducing cymbal sound spill you ll capture more drum sound. This enables engineers to EQ the drum increasing high end for more attack without accentuating cymbal sound. Engineers will also have an improved ability to balance each sound on close proximity sources like hi-hats or snares.
