Shure MX405R/MS 5 Inch Shock-Mount Gooseneck Mini Shotgun Microphone with LED Ring/Preamplifier

The MX405 is a gooseneck microphone with a Bi-Color LED or red light ring status display. It has a 12.7 cm / 5 inch gooseneck and is suitable for boardrooms and other sites where aesthetics are important.

Features:

• Gooseneck length: 5 inch / 12.7 cm
• Low profile, aesthetic design
• Wide dynamic range and smooth frequency response
• RF filtering with CommShield™ technology
• Status indicator: Bi-Color LED at gooseneck bottom or red light ring on gooseneck top

Specifications:
