Description:
The SM87A with the UR2 transmitter features the SM87A supercardioidPicks up most sound in front of the microphone and very little from the sides, making it more directional than a cardioid mic.

The flagship UR2 Wireless Handheld Transmitter offers the most advanced features and controls including a bit-mapped backlit LCD display, infrared automatic transmitter sync and switchable RF power. It also has frequencyThis is how many times a sound or radio wave oscillates in one second.Read moreGo to the glossary and power lockout cabability and can be used continuously for up to 8 hours using 2 x AA Batteries (included). The UR2 is made from an all-metal die-cast construction for maximum durability.
This transmitter requires the UR4D or UR4S receiver to complete the system.
All Shure wireless transmitter designs allow for interchangeable microphone heads

- NOTE: Overall system frequency responseThis is the range of frequencies, from the lowest to the highest, that a mic can pick up.
- Gain Adjustment Range: –10 to +20 dB
- Modulation: FM (45 kHz max. deviation), compander system with pre- and de-emphasis
- RF Power Output: 10 / 50 mW
- Dynamic RangeThis is the difference between the queitest and loudest sound that a mic can pick up.Read moreGo to the glossary: >105 dB, A-weighted
- Signal Polarity: Positive pressure on microphone diaphragm produces positive voltage on XLR output pin 2 with respect to XLR pin 3 and on the tip of the 1/4-inch output jack.
- System Distortion (ref. ± 45 kHz deviation, 1 kHz modulation): <0.3% Total Harmonic DistortionTotal Harmonic Distortion is a measure of how much electrical noise a device produces.
