Shure Model 512 combines an efficient “open-air” headphone with a close-talking dynamic microphone. The unit is unobtrusive, durable, comfortable, and provides a wide frequency range.

The 512 was designed for sports and news announcing, intercommunications systems, and special events remote broadcasting. It offers convenient hands-free operation, and a lightweight frame to reduce user fatigue. The unidirectional pickup pattern reduces unwanted background noise, permitting its use in noisy environments. The microphone characteristics are tightly controlled resulting in consistent response and output, and the headphone response is tailored to enhance voice intelligibility.

The headband easily adjusts to fit a variety of head sizes and hairstyles, and the microphone boom can be adjusted to accurately place the microphone cartridge at the corner of the user’s mouth.

The microphone is supplied with a foam windscreen to reduce explosive “popping” sounds, and a cable clip to secure the cable to clothing.

USING THE MICROPHONE

Snap the microphone boom into the rotating holder below the left earpiece. Put on the headset and adjust the earpads to the most comfortable position. The headset is designed for use with the microphone mounted on the left side. Slide and twist the microphone boom and rotate its holder until the microphone is located as close as possible to the left corner of the mouth (not directly in front).
