The SHURE's 515S-BG18XF is a tough portable dynamic microphone with a 5/8"-27 thread for attachment on common microphone stands. The frequency response has been tuned to reduce low-frequency noise and record speech with the highest level of intelligibility possible. The cardioid polar pattern eliminates feedback and noise from the capsule's off-axis regions. The 515BSM comes with a 5-conductor cable that is permanently connected and has an unterminated end, allowing you to wire in a connector that is suited for your configuration. The cable's two additional leads are utilised to connect an external relay or control circuit.
