The dbx RTA-M Reference Microphone is a precision omnidirectional measurement microphone designed specifically for use with dbx DriveRack series loudspeaker management systems. It provides an accurate acoustic snapshot of a room, allowing sound engineers, DJs, and installers to fine-tune PA systems for optimal clarity, balance, and performance.

With its flat frequency response and omnidirectional pickup pattern, the RTA-M captures an accurate representation of the sound field for reliable real-time analysis and “pink noise” system calibration. When paired with a compatible DriveRack processor, the microphone enables automated EQ adjustments that adapt your system to the acoustics of each venue.

Built with a rugged metal housing, the RTA-M is designed for professional use in live sound, touring, installations, and recording environments. It operates on standard phantom power (9–52 VDC) supplied by DriveRack units and includes a microphone clip and protective hard case for safe transport and storage.
