Customer Review Summary

The DBX DriveRack RTA-M microphone is an exceptional tool for sound analysis and equalisation, particularly when paired with the DBX DriveRack PA2. Its compact design and impressive frequency response make it ideal for various applications, from live sound reinforcement to studio recordings.

This microphone excels in capturing real-time audio analysis, allowing users to optimise the sound quality of their systems effectively. Many have noted its ability to deliver a flat frequency response, which is crucial for accurate sound measurements. While some users have mentioned the need for a calibrated measurement specification to achieve the best results, the overall performance remains commendable, especially considering its price point.

Durability is another strong point, as the microphone is designed to withstand robust environments, making it a reliable choice for both professionals and enthusiasts. The included case, although somewhat bulky, provides excellent protection during transport, ensuring the microphone remains safe and secure.

However, it’s important to be aware of a few quirks, such as the reversed polarity, which can potentially lead to measurement inaccuracies if not noted. Despite this, the microphone is praised for its ease of use, making it a solid investment for anyone looking to enhance their audio setup.
