Neumann BCM 705 Dynamic Microphone

The frequency response is tailored to compensate bass boost due to the proximity effect. The headgrille and pop screen can be removed without the use of tools, permitting easy cleaning or replacement.

Features

• Headgrille twists off easily for quick cleaning.
• Individual headgrilles available for each user.
• Does not require a power supply.
• Integrated elastic suspension.
