dbx RTA-M Reference Microphone — Calibrated Room Analysis for DriveRack Systems

The dbx RTA-M is the manufacturer's dedicated measurement microphone for the DriveRack PA, PX, PA+, PA2, and 260 processors. As a flat-response omnidirectional reference tool, it captures the full acoustic signature of a venue so the Auto EQ Wizard can apply accurate corrections during system setup. This instrument is the right choice for live sound engineers who need a repeatable measurement chain for room tuning and pink-noise analysis.

Built for the DriveRack Ecosystem and the Road

Unlike generic measurement mics, this model shares its capsule with the M2 mic that ships with the DriveRack PX. The metal housing is more rugged than the M2's plastic body, and the included hardcover case protects the capsule between gigs. Phantom power is drawn straight from the DriveRack unit, so no external supply or battery is needed in the signal chain.

Technical Specifications — Designed for Accurate Real-Time Analysis

Every spec on this measurement microphone is tuned to deliver a clean, uncolored capture of room acoustics for the DriveRack's analysis routines.

• Element: Back Electret Condenser — stable response across the audible band
• The omnidirectional polar pattern picks up reflections and direct sound equally for a true room picture, without proximity bias from a single source direction.
• Frequency Response: 20 Hz - 20 kHz — covers the full range used by the DriveRack's pink-noise analysis
• Sensitivity: -63 dB ± 3 dB (0 dB = 1 V/microbar at 1 kHz, open circuit) — predictable output for system calibration
• Operating Voltage: 9-52 V DC phantom power — draws power directly from the DriveRack, no external supply needed

Who Should Use the RTA-M

This model is the right choice for live sound engineers, venue technicians, and AV integrators who already own or plan to deploy a DriveRack PA, PX, PA+, PA2, or 260 processor. Equally useful for house-of-worship teams, touring cover bands, and club installers, it helps tame difficult rooms before the first note plays.
