The Audio-Technica ATM350S Surface-Mount Instrument Microphone system provides a professional solution for capturing clear, well-balanced audio from accordions and other instruments with difficult mounting surfaces. This system utilizes the ATM350a cardioid condenser microphone, which handles high sound pressure levels (SPL) while maintaining a crisp response. The cardioid polar pattern minimizes sound pickup from the sides and rear to improve the isolation of the primary sound source.
The ATM350S includes the UniMount mounting system to ensure secure attachment and precise microphone placement. The AT8491S surface mount attaches either permanently or temporarily to instruments, offering integrated shock resistance for the microphone. The system features a rugged AT8490 5-inch gooseneck that maintains its shape during aggressive performances, keeping the microphone accurately positioned.
An in-line power module provides the necessary interface for the microphone and includes a switchable 80 Hz high-pass filter. This filter helps control undesired low-frequency noise and ambient interference. For expanded versatility, the system supports interchangeable elements to provide hypercardioid and omnidirectional polar patterns.
The low-profile design of the ATM350S ensures minimum visibility during performances. In addition to the surface mount, the package includes an AT8468 violin mount with a hook-and-loop fastener for alternative instrument configurations. A protective carrying case is included to safeguard the components during transport.
