The PR 40 Dynamic Cardioid Studio Microphone from Heil Sound is a high-performance dynamic microphone ideal for use as a vocal mic for talk-show hosts and other voice-over applications. The large dynamic element produces a smooth response with an articulate and natural midrange. The size of the diaphragm, combined with a low mass and an efficient NdFeB magnet structure, allow the microphone to achieve a wide dynamic range and capture high SPLs, making it a great kick drum mic as well.

This front-address microphone has 4 rear ports to reject off-axis noise, resulting in a smooth, tight cardioid pickup pattern with reduced proximity effect. The steel body and internal humbucking coil shield the microphone, making it safe for use near video monitors and noisy lighting fixtures. An internal Sorbothane shockmount decouples the microphone's dynamic element from the body to reduce the effects of handling noise.
