Audient RM1 Reference Calibration Mic

The Audient RM1™ Reference Microphone is an individually calibrated, omnidirectional MEMS measurement microphone with a 20 Hz to 20 kHz frequency range for RoomTune™ Monitor Correction on Audient iDMK3 audio interfaces.

Individual Calibration for Accurate Room Measurement

Audient calibrates every RM1 individually and assigns each microphone a unique frequency response profile. During setup, RoomTune loads the correct profile when the engineer enters the microphone’s serial number. This calibration allows the software to account for the response of that specific microphone when measuring the monitoring system.

The MEMS capsule supports consistent measurements over time, while its omnidirectional pickup captures sound from all directions. Its 20 Hz to 20 kHz frequency range spans the audible spectrum, providing the measurement coverage that RoomTune needs to assess monitor playback in the listening environment.

Automatic RoomTune™ Setup

RoomTune automatically configures 48 V phantom power, microphone gain, monitor level and latency compensation. The engineer positions the microphone and enters its serial number, while the software manages the measurement settings without manual gain or level adjustment.

Audient develops the microphone, software and compatible interfaces together, allowing RoomTune to coordinate the measurement process and check for errors as it proceeds. This integrated approach simplifies setup and helps engineers obtain reliable measurements with less manual configuration.

Monitor Correction for Audient iDMK3 Interfaces

The RM1 requires an Audient iDMK3 interface and works with the iD1, iD2, iD2+ and iD4+. Audient includes RoomTune software at no extra cost with every iDMK3 interface, and RoomTune requires the RM1 to set up monitor correction.

RoomTune uses the measurement data to apply monitor correction on the interface, reducing the room’s influence on playback. This helps engineers assess tonal balance more accurately and make mix decisions that translate more reliably across other playback systems. The RM1 also allows fresh measurements whenever monitor positions or room layouts change.

Every compatible iDMK3 interface shares Audient Console Mic Preamps for microphone amplification, 32-bit audio conversion and the Analogue Tone Suite for tonal shaping, alongside RoomTune Monitor Correction.

XLR Connectivity and Measurement Performance

The RM1 connects to the interface via XLR and requires 48 V phantom power, which RoomTune configures during setup. Its 56 g weight makes repositioning straightforward during measurement sessions.

A 70.5 dB signal-to-noise ratio supports clear measurement capture, while Audient specifies 0.1% total harmonic distortion and a maximum sound pressure level of 130 dB. Together, these figures describe the microphone’s noise performance, harmonic distortion and sound pressure handling capability.
