dbx RTA-M Reference Microphone
Description
dbx RTA-M Reference Microphone
The dbx RTA-M delivers transparent, articulate sound reproduction that captures the true character of your instrument or vocals without coloration. Built for studio recording, live performance, and acoustic measurement work, this reference microphone's rugged metal construction and balanced weight distribution ensure consistent results across sessions. A presence peak in the midrange adds clarity that sits well in dense mixes, while the smooth low-end rolloff keeps muddy frequencies from clouding your recordings.
Design & Build
Constructed with a metal housing designed for durability and consistent performance in professional environments, the RTA-M features a back electret condenser element that delivers reliable operation across demanding applications. The omnidirectional polar pattern captures sound equally from all directions, making it a versatile tool for tracking instruments, recording vocals, and performing acoustic room analysis during mixing and mastering work.
Audio Performance
With a frequency response spanning 20 Hz to 20 kHz and sensitivity rated at -63 dB ±3 dB, the RTA-M provides the frequency coverage and input level accuracy needed for honest, usable tone in any recording situation. An impedance of 250 Ohms ± 30% ensures proper interface with standard mixing consoles and audio interfaces without signal loss or impedance mismatch complications.

Frequently Asked Questions
What polar pattern does the RTA-M have, and what is it best for miking?
The RTA-M features an omnidirectional polar pattern, meaning it captures sound equally from all directions. This makes it versatile for instrument miking, vocal recording, and room measurement work in both studio and live settings.
What phantom power does the RTA-M require?
The RTA-M requires 9 to 52 VDC phantom power, which is standard on most modern mixing consoles and audio interfaces. The 250 Ohm impedance (±30%) ensures proper interface without signal loss or impedance mismatch.
How does the frequency response and presence peak affect recordings?
The RTA-M spans 20 Hz to 20 kHz with a presence peak in the midrange that adds clarity and definition to cut through dense mixes, while a smooth low-end rolloff removes muddy frequencies and keeps recordings tight.
What is included with the RTA-M?
The RTA-M ships with a microphone clip and hardcover case for protection and transport.
How does the RTA-M compare to similar reference mics like the Shure SM137 or Audio-Technica AT4021?
The RTA-M delivers transparent, articulate sound with a presence peak designed to cut through and a smooth low-end rolloff, positioning it as a budget-friendly reference mic comparable to the Shure SM137 and Audio-Technica AT4021, with rugged metal construction and reliable phantom-powered operation across studio, live, and measurement applications.
