    • Amazing 14 hour battery life
Style: Handheld Transmitter w/ Mic Capsule Only Pattern Name: H9 Band (512-542 MHz)
This is replacement for another brand. Previous model had an LED screen, showing you if it was on, or muted. You need to use the Shure chart to ensure that your mic is legal in your area of the country (US). I have no idea what folks who travel a lot (musicians/speakers) do to meet these requirements. I thought I'd miss the mute button. I don't. Users at church start playing with the buttons, and that takes the control away from the folks at the sound board. They can turn it off, or on. Remove the battery cap, and you'll find the controls to connect to a Shure receiver. I don't have enough receivers, so I connected this to one of the existing ones ... can't use the headset, and this at the same time, however, you can use one at a time. The gain is different, therefore I set our x32 Behringer to the lower gain value. I have to turn this mic up each time (only since I'm sharing a receiver). Battery life is amazing! We also have some 9v mics (this one uses (2 AA) that don't last nearly that long. We regularly use rechargeable batteries, and that's worked out really well. Just to be sure we check the battery level before use. After several uses no battery issues. This mic you can use at lips or about 8" away without issue. As with any mic it works best when closest to the sound source. Overall very pleased, and will be purchasing a receiver so we don't have to share a channel between mics. We're slowly moving to all Shure equipment for compatibility. ... show more
