dbx RTA-M Reference Microphone

dbx RTA-M Reference Microphone

The dbx RTA-M captures your instrument or vocals with transparent, articulate clarity—no coloration, just the true character of your sound. Built tough with a metal housing that can take whatever the road throws at it, this reference mic performs equally well live on stage, in the studio, or as a measurement tool. A presence peak in the midrange cuts through dense mixes and lets your tone shine, while the smooth low-end rolloff keeps the mud out of your signal.

Design & Build

The RTA-M is engineered with a durable metal housing built to survive years of gigging and studio work without losing its voice. Powered by a back electret condenser element, it delivers rock-solid operation no matter how demanding your gig schedule gets. Its omnidirectional polar pattern makes it equally useful for capturing your amp, recording vocals, or taking acoustic measurements in any space.

Audio Performance

With a frequency response that spans 20 Hz to 20 kHz and sensitivity rated at -63 dB ±3 dB, the RTA-M gives you the full frequency coverage and input accuracy you need to capture honest, usable tone in any session. An impedance of 250 Ohms ± 30% means it pairs seamlessly with standard mixing consoles and audio interfaces without signal loss or impedance headaches.
