For capturing audio, the QLXD2/KSM8 Handheld Wireless Microphone Transmitter by Shure is a good choice to get the job done. Featuring a cardioid polar pattern and transparent 24-bit digital audio quality, it is used for wireless vocals in presentation spaces, music venues, houses of worship, DJ setups, and more. It features a 20 Hz to 20 kHz frequency response and has more than 60 available channels per frequency band. Powered by 2 AA batteries, the QLXD2 quickly syncs with a wireless receiver – sold separately – over IR at the push of a button and maintains clear, uninterrupted signal over its entire 100m (328') range. All-metal construction ensures durability, and a wide selection of compatible microphone choices is ideal for your presentation.
Patented cartridge design featuring two ultra-thin diaphragms (one active and one passive) and groundbreaking inverted airflow system
Exceptional control of proximity effect vastly increases working distance without on-axis coloration
Accurate frequency response due to controlled proximity effect which allows for neutral mid-and-high frequency reproduction
Off-axis attenuation is flat and broad resulting in superior quality of rejection of unwanted sound sources for increased vocal clarity
Shock Mount design for exceptional rejection of handling noise without any loss of low frequency response
Dent-resistant, hardened carbon-steel grille design lined with hydrophobic woven fabric provides exceptional plosive and wind protection, while offering virtually waterproof protection
