The Heil Sound PR 20 SUT is a handheld cardioid dynamic microphone designed for articulate reproduction of vocals, speech, instruments, amplifier cabinets, and drums in studios, clubs, houses of worship, and live stage applications. Though sonically identical to the PR 20, the PR 20 SUT sports a stainless steel grille in place of the PR 20's interchangeable silver, black, and gold grilles. The dynamic microphone element features a composite magnet for increased strength and a cardioid polar pattern, which provides significant rear rejection and immunity to feedback. With a 145 dB maximum SPL and a frequency response of 50 Hz to 18 kHz, it is well suited to a wide variety of sources.Plosives and wind noise are attenuated via the included foam windscreen. An on/off switch allows easy muting between announcements, bands, or sets. The balanced XLR 3-pin output ensures compatibility with most microphone preamps, mixer inputs, portable PA systems, and audio interfaces. A mic clip and carrying bag are also included with the PR 20 SUT.
