Audio-Technica ATM350U - Cardioid Condenser Instrument Microphone with Universal Clip-On Mount
Product Details
Product Features
The Audio-Technica ATM350U pairs the ATM350a miniature cardioid condenser microphone with a universal clip-on mounting system for brass, saxophone and other instruments. It handles very high sound pressure levels with a clear, balanced response.
The rubber-lined metal AT8491U clip locks onto the instrument bell, and the 5-inch gooseneck holds its position during play. 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
- AT8491U universal clip-on mount attaches to the instrument bell and resists shock
- 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
