dbx RTA-M measurement microphone

The dbx RTA-M is a precision measurement microphone designed for accurate sound system analysis and room equalization. Featuring a 1/2-inch electret condenser capsule with an omnidirectional polar pattern, it captures sound evenly from all directions, making it ideal for real-time analyzers and acoustic measurement software. The microphone offers a flat frequency response of 20 Hz to 20 kHz within ±1 dB, ensuring reliable and repeatable measurements for professional audio engineers.

Built with a rugged metal housing and a standard XLR connector, the RTA-M requires 48V phantom power for operation. Its low self-noise and high SPL handling capability allow for precise measurements in both quiet and loud environments. Whether used for setting up PA systems, tuning studio monitors, or conducting acoustic research, the dbx RTA-M delivers consistent performance and accuracy.
