Shure SLX - Countryman E6i Combination System   This Wireless Earset/Headset package includes: (1) Countryman E6i Earset Microphone (1) Shure SLX Wireless System   Countryman E6i earset microphone The ultimate microphone for your pastor. The Countryman EarSet microphone is a world-class vocal mic so unobtrusive it’s barely seen as it delivers high quality voice pickup, while rejecting surrounding noise and feedback. An ultra-miniature electret condenser element is held close to the mouth by a thin boom and comfortable earclip. The entire assembly weighs less than one-tenth ounce and virtually disappears against the skin, so performers forget they’re even wearing a mic. The Omnidirectional element is nearly immune to wind and breath pops, even when used without a windscreen, while the boom keeps it very close to the mouth for excellent isolation. The Directional Earset is a top choice for any spoken word application with excessive background noise or potential for feedback. How do I choose the right color for my skin tone? Tan is the most popular color choice, because it works perfectly for average Caucasian skin tones, as well as olive complexions. Light beige works well in theatrical applications due to its slightly pink undertone, which is also appropriate for extremely fair skin. Cocoa is the ideal choice for African American skin tones ranging from very light to chocolate, and black is appropriate for extremely dark skin, or for situations where you want the mic to be visible. When in doubt, choose the darker option. That's because a mic that's too light can resemble a scar or blemish, while a mic that's slightly darker than the background tends to blend much better and draws less attention. Which sensitivity should I choose? Making a microphone more sensitive to catch soft sounds means it will overload sooner for loud sounds. Because sound pressure levels vary between individuals and applications, we provide three sensitivities with three overload or clipping characteristics. The most sensitive (W5, no band) is for general speaking, such as presentations or sermons The middle sensitivity (W6, blue band) is for vocals and strong speaking, such as in theater The most powerful vocals require the least sensitive mic (W7, purple band) with the highest overload sound level Which cap should I use? The Earset should always be used with a protective cap in place to keep sweat, makeup and other foreign material out of the microphone. The three omni caps each have a different high frequency response characteristic that controls the amount of "crispness" or "sibilance" (response at 15 kHz). The omni ships with the +4 dB protective cap fitted to the mic. We have found that this cap's frequency response meets the needs of the majority of users, providing a slightly increased response in the 15 kHz range. This will boost the perceived amount of "presence" in your sound, while leaving the lower frequencies unchanged. If you experience problems with high-frequency feedback, you should switch to the 0 dB cap.
