Audio-Technica ATM350S - Cardioid Condenser Instrument Microphone with Surface Mount
Product Details
Product Features
The Audio-Technica ATM350S pairs the ATM350a miniature cardioid condenser microphone with a surface mounting system for accordions and other instruments that are hard to mic with clamps. The mic stays in place while the performer moves.
The AT8491S surface mount and AT8475 surface mounting kit allow permanent or temporary attachment, and the 5-inch gooseneck sets the capsule position. The AT8543 power module provides the XLR output and a switchable 80 Hz high-pass filter.
Key Features:
- Low-profile ATM350a cardioid condenser capsule for minimal visibility
- Clear, balanced response even at high sound pressure levels (159 dB SPL max)
- Cardioid pattern reduces pickup from the sides and rear
- AT8491S surface mount and AT8475 kit attach permanently or temporarily
- Rigid UniMount 5" gooseneck holds position during energetic playing
- AT8543 power module with switchable 80 Hz high-pass filter
- Optional UE-H hypercardioid and UE-O omnidirectional elements available separately
- Includes AT8468 violin mount and protective carrying case
