ATM75 specifications

The Audio-Technica ATM75 is a highly regarded headset microphone designed for applications that require high-quality audio capture in a lightweight and discreet format. Perfect for broadcasting, theater performances, and other live sound situations, this microphone combines innovative technology with user-friendly features.

One of the standout characteristics of the ATM75 is its lightweight and low-profile design. Weighing in at just a few ounces, it is engineered for comfort and long usage periods. This design is especially advantageous for performers and presenters who need to communicate clearly and effectively without the distraction of bulky equipment. The unobtrusive nature of the microphone allows for natural movement, making it an excellent choice for actors on stage or speakers engaged in dynamic presentations.

The ATM75 is equipped with a hypercardioid polar pattern, which helps isolate the sound source while minimizing background noise. This feature is pivotal in environments where unwanted ambient noise can interfere with clarity. The hypercardioid design captures sound primarily from the front, ensuring that the speaker's voice is the focus, providing exceptional audio quality.

Another defining aspect of the ATM75 is its frequency response. Engineered to deliver a wide frequency range, it ensures that voices sound natural and rich. The microphone performs exceptionally well in various settings, from musical performances to corporate events, consistently capturing the nuances of speech and vocal expression.

The microphone also incorporates a detachable cable, allowing users to easily replace or upgrade the cable as needed. This feature not only enhances the microphone's durability but also adds to its versatility. The rugged construction of the microphone ensures reliability, critical in live performance situations where equipment must withstand the rigors of travel and stage use.

In terms of compatibility, the ATM75 is designed to work seamlessly with a broad range of wireless systems, making it an ideal choice for those already invested in Audio-Technica products. The microphone can be easily paired with different transmitters, providing flexibility for users across multiple platforms.

An adjustable headband and a variety of included accessories, such as windscreen and microphone clips, further enhance the user experience, allowing for customized fitting and positioning.

With its combination of advanced technology, user-oriented design, and robust build, the Audio-Technica ATM75 remains a top choice for professionals seeking reliable audio solutions in demanding environments. Whether for performance, presentations, or videography, the ATM75 provides quality sound that professionals can trust.
